Effectiveness of pelvic floor muscle biofeedback electrical stimulation combined with pelvic floor muscle training for mild to moderate postpartum stress urinary incontinence / 中华围产医学杂志

Objective:To analyze the effects of pelvic floor muscle biofeedback electrical stimulation (PEMS) combined with pelvic floor muscle training (PFMT) and PFMT alone on mild to moderate stress urinary incontinence (SUI) after delivery.Methods:This retrospective study involved 1 087 postpartum women with mild or moderate SUI who were admitted to the Affiliated Hospital of Jining Medical University from January 2017 to January 2021. According to the treatment approaches, they were divided into two groups: the PMES+PFMT group ( n=504) and the PFMT group ( n=583). Chi-square test, independent sample t-test and rank sum test were used to compare the objective indicators (pelvic floor muscle strength test, vaginal dynamic pressure value test, 1-h pad test) and subjective indicators [incontinence impact questionnaire short form (IIQ-7), incontinence questionnaire-urinary incontinence short form (ICI-Q-SF), pelvic organ prolapse/urinary incontinence sexual function questionnaire (PISQ-12)] before, immediate and three months after treatment between the two groups. Results:There was no significant difference between the two groups in the values of vaginal dynamic pressure before treatment, 1-h pad test results and subjective indicators (all P>0.05). Comparison within groups: Indicators were improved in both groups immediate and three months after treatment compared with before treatment, including strength of type Ⅰ muscle [PMES+PFMT group: grade 4 and 5 (normal): 43.5% (219/504) and 42.1% (212/504) vs 1.2% (6/504), χ 2=864.27 and 861.46; PFMT group: grade 4 and 5:19.2% (112/583) and 20.1% (117/583) vs 1.5% (9/583), χ 2=1 148.26 and 1 038.29] and class Ⅱ muscle strength [PMES+PFMT group: 48.4% (244/504) and 50.8% (256/504) vs 4.8% (24/504), χ 2=862.96 and 819.24; PFMT group: 37.4% (218/583) and 38.9% (227/583) vs 5.0% (29/583), χ 2=1 029.47 and 998.54; all P < 0.05].Vaginal dynamic pressure increased [PMES+PFMT group: (89.3±5.4) and (82.2±4.6) vs (67.5±12.7) cmH 2O (1 cmH 2O=0.098 kPa), t=802.13 and 845.54; PFMT group:(80.2±4.3) and (78.6±4.5) vs (66.9±14.2) cmH 2O, t=288.37 and 244.94], and 1-hour urine leakage reduced [PMES+PFMT group: 2.0 g (2.0-3.0 g) and 2.0 g (1.0-3.0 g) vs 6.0 g (5.0-6.0 g), Z=825.39 and 802.13; PFMT group: 4.0 g (3.0-5.0 g) and 3.0 g (3.0-4.0 g) vs 5.0 g (4.0-6.0 g), Z=836.34 and 811.25], and IIQ-7 scores [PMES+PFMT group: scores of 3 (2-4) and 4 (3-4) vs 8 (7-9), Z=959.52 and 825.87; PFMT group: 5 (4-5) and 5 (4-6) vs 8 (7-10), Z=916.27 and 903.18], and ICI-Q-SF score [PMES+PFMT group: 3.5 (3-4) and 4 (3-5) vs 10 (9-12), Z=952.79 and 924.94; PFMT group: 6 (4-7) and 6 (5-7) vs 11 (10-12), Z=1 049.89 and 998.15], and PISQ-12 score [PMES+PFMT group: 10 (7-12) and 9 (7-12) vs 21 (17-24), Z=862.55 and 887.17; PFMT group: 13 (11-16) and 14 (12-16) vs 22 (18-25), Z=1 026.73 and 934.86, all P<0.05) decreased. Compared with the PFMT group, the above indexes were all better in the PMES+PFMT group (all P<0.05). Conclusion:PFMT alone or in combination with PMES can both enhance pelvic floor muscle strength, increase vaginal dynamic pressure, alleviate urine leakage and improve the quality of life and PMES+PFMT is better and more effective.

Aleitamento materno: prevalência e fatores condicionantes em uma cidade do interior da região da zona da mata mineira / Breastfeeding: prevalence and conditioning factors in na inland city in the region of the mata mineira zone

: O aleitamento materno, de acordo com a Organização Mundial da Saúde, deve ser o único alimento para os bebês até 6 meses de idade e o principal para as crianças de até 24 meses de idade. Entre suas inúmeras vantagens destaca-se menores índices de morbidade infantil por diarreia, infecções respiratórias, otite média, proteção contra sobrepeso e diabetes. Objetivo: O objetivo do estudo foi analisar a prevalência e os fatores condicionantes ao aleitamento materno das gestantes e lactantes investigadas, notando os padrões à implementação na rotina materna e suas dificuldades à essa prática. Metodologia: Trata-se de um estudo descritivo, quantitativo com delineamento transversal. A coleta de dados foi realizada através de um questionário semiestruturado, para conhecimento materno em aleitamento, realizado com gestantes e puérperas cadastradas em uma Unidade de Saúde localizada no município de Ubá, Minas Gerais, caracterizando uma amostragem não-probabilística de 118 mulheres. Resultados: Considerando o conhecimento do termo Aleitamento Materno Exclusivo, 56,7% das mulheres entrevistadas relataram não saber, no momento da entrevista, seu significado; 23,7% relataram achar que existem situações em que o bebê não deva ser amamentado ou que a prática deva ser interrompida; 19,4% das mulheres relataram achar que existe "leite fraco", enquanto 100% acreditam ser um alimento adequado ao bebê. Conclusão: Neste estudo foi verificado que a disseminação de informações a respeito do aleitamento materno, apesar de já ter alcançado muitas mulheres, o número de mães que amamentam de forma correta, mesmo tendo recebido informações a respeito e as que amamentam até a idade adequada, ainda é baixo

Breastfeeding, according to the World Health Organization, should be the only food for babies up to 6 months of age and the main food for children up to 24 months of age. Among its many advantages, there are lower rates of infant morbidity due to diarrhea, respiratory infections, otitis media, protection against overweight and diabetes. Objective: The aim of the study was to analyze the prevalence and conditioning factors for breastfeeding among the investigated pregnant and lactating women, noting the standards for implementation in the maternal routine and their difficulties with this practice. Methods: This is a descriptive, quantitative study with a cross-sectional design. Data collection was carried out through a semi-structured questionnaire for maternal knowledge about breastfeeding, carried out with pregnant and postpartum women registered at a Health Unit located in the city of Ubá, Minas Gerais, featuring a non-probabilistic sample of 118 women. Results: Considering the knowledge of the term Exclusive Breastfeeding, 56.7% of the women interviewed reported not knowing, at the time of the interview, its meaning; 23.7% reported thinking that there are situations in which the baby should not be breastfed or that the practice should be interrupted; 19.4% of the women reported that they thought there was "weak milk", while 100% believed that it was a suitable food for the baby. Conclusion: In this study, it was verified that the dissemination of information about breastfeeding, despite having already reached many women, the number of mothers who breastfeed correctly, even having received information about it and those who breastfeed until the appropriate age, is still low

Malformación arteriovenosa uterina como causa de hemorragia puerperal tardía / Uterine arteriovenous malformation as a cause of late puerperal hemorrhage

Resumen ANTECEDENTES: Las malformaciones arteriovenosas uterinas constituyen una causa infrecuente de hemorragia puerperal, en la bibliografía solo se encontraron 150 casos. Su conocimiento es importante porque son potencialmente mortales y porque se ha registrado un aumento en los últimos años. Suelen estar relacionadas con intervenciones en el útero: legrados, cesáreas o miomectomías o asociadas con neoplasias (enfermedad trofoblástica gestacional o adenocarcinoma endometrial), aunque otras son congénitas. CASO CLÍNICO: Paciente de 32 años, con una conización cervical y ablación de un mioma uterino mediante radiofrecuencia como únicos antecedentes de interés. A los 15 días posteriores a un parto eutócico, que fue el primero en su historial, tuvo un episodio de abundante metrorragia. En el puerperio inmediato tuvo una hemorragia abundante que requirió la transfusión de dos concentrados de hematíes. En la ecografía transvaginal el útero se observó de 22 x 44 mm, que podría corresponder a un cotiledón retenido. Ante la persistencia del sangrado se colocó un taponamiento intracavitario con una sonda de Foley con lo que se consiguió el cese del sangrado. Luego de descartar la embolización de las arterias uterinas debido al gran tamaño de la malformación arteriovenosa, se procedió a la histerectomía total simple por vía laparotómica. CONCLUSIÓN: Las malformaciones arteriovenosas uterinas, aunque son una causa infrecuente de hemorragia puerperal, deben ser sospechadas en virtud de ser potencialmente mortales.

Abstract BACKGROUND: Uterine arteriovenous malformations are a rare cause of puerperal hemorrhage, with only 150 cases reported in the literature. Their knowledge is important because they are life-threatening and because there has been an increase in recent years. They are usually related to interventions in the uterus: curettage, caesarean section or myomectomy or associated with neoplasms (gestational trophoblastic disease or endometrial adenocarcinoma), although others are congenital. CLINICAL CASE: A 32-year-old patient with a cervical conization and ablation of a uterine myoma by radiofrequency as the only history of interest. Fifteen days after a euthecological delivery, which was the first in her history, she had an episode of abundant metrorrhagia. In the immediate postpartum period, she had a heavy hemorrhage that required the transfusion of two red blood cell concentrates. Transvaginal ultrasound showed a uterus measuring 22 x 44 mm, which could correspond to a retained cotyledon. In view of the persistent bleeding, intracavitary tamponade was placed with a Foley catheter, which led to cessation of bleeding. After ruling out embolization of the uterine arteries due to the large size of the arteriovenous malformation, a simple total hysterectomy by laparotomy was performed. CONCLUSION: Uterine arteriovenous malformations, although an infrequent cause of puerperal hemorrhage, should be suspected because they are potentially fatal.

Mother-infant bonding and postpartum depression during the COVID-19 pandemic — a risk for nurturing care and child development / Vínculo mãe-bebê e depressão pós-parto durante a pandemia de COVID-19 — um risco para o nurturing care e o desenvolvimento da criança

ABSTRACT Objective: The COVID-19 pandemic Increased the risk of impairing the mother-infant bonding. The objectives of this study were to evaluate the early bond established between mother and infant and postpartum depression (PPD) in pregnancies that occurred during the pandemic period, to identify the factors that may have influenced these outcomes and to verify if there was an association between bonding and probable PPD. Methods: This is a cross-sectional study of postpartum women from a public maternity hospital in the city of São Paulo conducted from February to June 2021, involving 127 mother-baby dyads. The initial data were collected in the immediate postpartum period and between 21-45 days after birth, using a semi-structured questionnaire on sociodemographic characteristics, gestational and birth conditions, and baby characteristics; the Edinburgh Postnatal Depression Scale (EPDS) and Postpartum Bonding Questionnaire (PBQ) were used to evaluate PPD and bonding, respectively. Results: The presence of probable PPD and unplanned pregnancies were associated with higher PBQ score and risk to impaired bonding (p = 0.001 and p = 0.004, respectively). EPDS showed a high prevalence of PPD (29.1%) and was not associated with any Studied variable. Probably, this high prevalence of probable PPD was due to the context of insecurity secondary to the pandemic. Conclusions: We observed an increase in the prevalence of probable PPD and unplanned pregnancies during the first 18 months of the pandemic, which were associated with worse scores in mother-infant bonding. The impaired bond can affect the future development of children born during this period.

RESUMO Objetivo: A pandemia do COVID-19 aumentou o risco de o vínculo entre mãe-bebê ser prejudicado. Os objetivos deste estudo foram avaliar o vínculo mãe-bebê estabelecido precocemente e a depressão puerperal (DP) em gestações que ocorreram durante a pandemia, identificar os fatores que podem ter influenciado esses resultados e verificar se houve associação entre o vínculo e a provável depressão puerperal. Métodos: Foi realizado um estudo transversal com puérperas de uma maternidade pública da cidade de São Paulo, no período de fevereiro a junho de 2021, envolvendo 127 díades mãe-bebê. Os dados foram obtidos no puerpério imediato e 21 a 45 dias após o parto, utilizando-se um questionário semiestruturado sobre as características sociodemográficas, as condições de gestação e nascimento e características do recém-nascido; a escala de depressão puerperal de Edimburgo (EPDS) e o questionário de vínculo pós-parto (PBQ) foram utilizados para avaliar a presença de provável DP e o vínculo mãe-bebê, respectivamente. Resultados: A presença de provável DP e as gestações não planejadas foram associadas a maiores escores no PBQ e no risco de vínculo prejudicado (p = 0,001 e p = 0,004, respectivamente). A escala de Edimburgo mostrou alta prevalência de risco de depressão puerperal (29,1%) e não foi associada a nenhuma variável estudada. Provavelmente, a alta prevalência de provável DP foi secundária ao contexto de insegurança decorrente da pandemia. Conclusões: Observamos aumento na prevalência da provável DP e das gestações não planejadas durante os primeiros 18 meses da pandemia, os quais estiveram associados a piores escores no vínculo mãe-bebê. O prejuízo no vínculo pode afetar o desenvolvimento futuro das crianças geradas durante esse período.

Puerperium Online: interactions of a virtual support group / Online no puerpério: interações de um grupo de apoio virtual

Abstract Objectives: due to the accessibility, online support groups have been used as an alternative in the constitution of a support network for women in the puerperium period. Thus, this resource is given relatively a short time of use, the present work sought to present an overview of the virtual group of puerperal women's interactions. Methods: qualitative and exploratory study that analyzed a virtual group composed of 9 pregnant women's interactions, predominantly during the puerperium period, users of basic health services in the city of Currais Novos/RN, during the period of January to June 2020. The corpus, duly previously prepared, was submitted to Análise da Classificação Hierárquica Descendente (ACHD) (Analysis of Descending Hierarchical Classification) via IRAMUTEQ software, followed by content analysis, according to Bardin. Results: the ACHD resulted in convergence around three themes, with class 1 - "Puerperium Itinerary", which represented 56.1% of the elementary context units (ECUs) of the total corpus, being the object of interest in the present study. The main dimensions extracted from this class dealt with difficulties inherent to daily life and demands for support and care during the puerperium period, as well as the limitations inherent to this moment. Conclusions: it was noticed that virtual groups can strengthen the support network necessities to face the difficulties of the puerperium by exchanging experiences.

Resumo Objetivos: por sua acessibilidade, os grupos de suporte online vem sendo utilizados como alternativa na constituição da rede de apoio às mulheres no puerpério. Assim, dado o relativo pouco tempo de utilização deste recurso, o presente trabalho buscou apresentar uma visão geral das interações de um grupo virtual de puérperas. Métodos: estudo de caráter qualitativo e exploratório que analisou as interações de um grupo virtual composto por 9 mulheres gestantes, predominantemente durante o puerpério, usuárias dos serviços básicos de saúde do Município de Currais Novos/RN, durante o período de janeiro a junho de 2020. O corpus, devidamente previamente preparado, foi submetido a Análise da Classificação Hierárquica Descendente (ACHD) via software IRAMUTEQ, seguida de análise de conteúdo, de acordo com Bardin. Resultados: a ACHD resultou em convergência em torno de três temas, sendo a classe 1 - "Itinerários do Puerpério", que representou 56,1% das unidades de contexto elementar (UCE) do corpus total, o objeto de interesse do presente estudo. As principais dimensões extraídas desta classe trataram de dificuldades inerentes ao cotidiano e demandas de apoio e cuidados durante o puerpério, bem como as limitações inerentes a este momento. Conclusão: percebeu-se que grupos virtuais podem atuar fortalecendo a rede de apoio necessária ao enfrentamento das dificuldades do puerpério a partir da troca de experiências.

Psaudoaneurisma de la arteria hipogástrica izquierda, una causa extremadamente rara de sangrado puerperal tardío / Pseudoaneurysm of the left hypogastric artery, an extremely rare cause of late puerperal late puerperal bleeding

Resumen ANTECEDENTES: La hemorragia puerperal tardía implica una importante morbilidad y mortalidad que requiere una actuación urgente. Su causa es muy variada y requiere una cuidadosa valoración que permita detenerla, sin complicaciones. CASO CLÍNICO: Paciente de 42 años que a las cinco semanas posteriores a una cesárea acudió a Urgencias debido a un sangrado puerperal abundante. Enseguida de un legrado y exhaustiva revisión en el quirófano en la ecografía se identificó un área parauterina anecogénica sugerente de dilatación aneurismática comunicada con la cavidad uterina. El diagnóstico se estableció con base en la angiografía y se confirmó luego de la embolización mediante radiología intervencionista, sin contratiempos, y resolución del cuadro. La paciente se dio de alta del hospital en los siguientes dos días, con posteriores revisiones que se reportaron normales. CONCLUSIONES: La patología vascular debe formar parte del diagnóstico diferencial del sangrado puerperal tardío y, si se diagnostica adecuadamente, puede facilitar el procedimiento terapéutico mediante radiología intervencionista y evitar, así, otros tratamientos más invasivos.

Abstract BACKGROUND: Late puerperal hemorrhage is a major morbidity and mortality that requires urgent action. Its cause is very varied and requires careful assessment to stop it without complications. CLINICAL CASE: A 42-year-old woman came to the emergency department five weeks after cesarean section for heavy puerperal bleeding. After curettage and thorough examination in the operating room, ultrasound identified an anechogenic parauterine area suggestive of aneurysmal dilatation in communication with the uterine cavity. The diagnosis was established based on angiography and confirmed after embolization by interventional radiology, without mishap, and resolution of the picture. The patient was discharged in two days, with subsequent revisions reported as normal. CONCLUSIONS: Vascular pathology should be part of the differential diagnosis of late puerperal hemorrhage and, if properly diagnosed, may facilitate the therapeutic procedure by interventional radiology and thus avoid other more invasive treatments.

Características relacionadas à ocorrência de infecção puerperal em mulheres submetidas ao parto cesáreo / Characteristics related to the occurrence of puerperal infection in women submitted to cesarrel delivery

Objetivo: Este artigo de revisão sistemática tem como objetivo analisar as principais características relacionadas à infeção puerperal em mulheres submetidas ao parto cesáreo. Fonte dos dados: Foi realizada busca nas bases de dados on-line Biblioteca Virtual de Saúde (BVS) e PubMed. Seleção dos estudos: Selecionaram-se artigos publicados nos últimos 11 anos (2010-2021), totalizando 12 artigos analisados. Coleta de dados: Realizou-se a busca dos artigos a partir dos descritores infecção puerperal, mortalidade materna, cesárea, fatores de risco em inglês e português. Em seguida à adequação aos critérios de inclusão (artigos em inglês, português e espanhol, com publicação nos últimos 11 anos, realizados em humanos) e exclusão (artigos duplicados, revisão de literatura, estudos de caso e dissertações), a análise dos títulos e dos resumos dos artigos encontrados permitiu a exclusão daqueles que se afastavam do tema em estudo. Síntese dos dados: Dentre os fatores sociodemográficos, destacam-se mulheres nos extremos de idade, negras, residentes na zona rural, com baixo nível econômico e escolar, primíparas e tabagistas. Em relação aos fatores clínicos, obesidade, HIV, diabetes mellitus, doenças cardiovasculares, hipertensão arterial, pré-eclâmpsia e eclâmpsia, anemia e infecções geniturinárias apresentaram-se como fatores de risco para infecção puerperal. Fatores obstétricos também foram avaliados, identificando-se como variáveis importantes o parto cesáreo, rotura prematura de membranas, tempo de membrana rota, trabalho de parto maior que 12 horas, parto prematuro e trabalho de parto induzido, hemorragia pós-parto, transfusão prévia e mecônio em líquido amniótico. Por fim, as características assistenciais trazem o baixo número de consultas de pré-natal e número de toques vaginais antes e após a ruptura de membranas como variáveis de risco. Conclusão: Muitos dos fatores identificados são passíveis de controle, e a sua reversão contribui para a redução dos índices de infecção puerperal e, consequentemente, de mortalidade materna.(AU)

Objective: This systematic review article aims to analyze the main characteristics related to puerperal infection in women undergoing cesarean delivery. Source of data: A search was performed in the online databases Virtual Health Library (VHL) and Pub- Med. Selection of studies: Articles published in the last 11 years were selected, totaling 12 analyzed articles. Data collection: Articles were searched based on the keywords puerperal infection, maternal mortality, cesarean section, risk factors in English and Portuguese. Following the adaptation to the inclusion criteria (articles in English, Portuguese and Spanish, publication in the last 11 years, carried out in humans) and exclusion (duplicates, literature review, case studies and dissertations), the analysis of the titles and abstracts of the found articles allowed the exclusion of those who departed from the topic under study. Summary of the findings: Among the sociodemographic factors, women of extreme age, blacks, residents in the rural area, with low economic and educational status, primiparous women and smokers, stand out. Regarding clinical factors, obesity, HIV, Diabetes Mellitus, Cardiovascular Diseases, Hypertension, Pre-eclampsia and Eclampsia, Anemia and genitourinary infections were risk factors for puerperal infection. Obstetric factors were also evaluated, identifying as important variables cesarean delivery, premature rupture of membranes, ruptured membrane time, labor longer than 12 hours, premature labor and induced labor, postpartum hemorrhage, previous transfusion and meconium in amniotic fluid. Finally, the care characteristics bring the low number of prenatal consultations, the number of vaginal touches before and after rupture of membranes as risk variables. Conclusion: Many of the identified factors are possible to control and their reversion contributes to the reduction of puerperal infection rates and consequently maternal mortality.(AU)

Early recognition and management of sepsis during pregnancy and puerperium / 中华围产医学杂志

Sepsis and septic shock are obstetric emergencies, which bring clinical issues for obstetricians to pay attention to, such as early identification and emergency intervention before transferring the patients to intensive care. Physiological changes during pregnancy and puerperium result in difficulty in identifying the clinical features of sepsis. Simple bedside screening tools can be used for early identification and screening for possible sepsis. If initial sepsis screening is positive with suspected or evidence of infection, regardless of the presence of fever, further evaluation of organ damage is required for the diagnosis of sepsis. Bundle therapy should be initiated within 1 h after the identification of sepsis: For pregnant women or puerpera with suspected or confirmed sepsis, bacterial culture (blood, urine, respiratory tract, and other body fluids) and serum lactate level detection should be conducted promptly, moreover, empirical broad-spectrum antibiotics given within 1 h are recommended; For patients with sepsis complicated by hypotension or organ hypoperfusion, it is recommended to administer 1-2 L crystal solution as soon as possible for liquid resuscitation; For those with persistent hypotension and/or organ hypoperfusion despite fluid resuscitation, vasopressors are recommended to maintain mean arterial pressure ≥65 mmHg (1 mmHg=0.133 kPa), with norepinephrine as the first-line vasopressor. When sepsis is suspected or confirmed, the focus of infection should be actively sought to effectively control the source. Termination of pregnancy should be considered individually and comprehensively on the basis of obstetric indications, gestational age, and maternal and fetal conditions, but not depend on sepsis alone. If intrauterine infection is confirmed, pregnancy should be terminated immediately. Cesarean delivery usually requires general anesthesia for pregnant women with sepsis and intraspinal anesthesia is relatively contraindicated. The diagnosis and treatment of sepsis in pregnancy and puerperium should be individualized in accordance with the corresponding guidelines.

Mechanism of Xiaoyong Sanjie Formula treating non-puerperal mastitis based on network pharmacology / 国际中医中药杂志

Objective:Based on network pharmacology and molecular docking to explore the targets and mechanism of Xiaoyong Sanjie Formula treating Non-Puerperal Mastitis (NPM).Methods:By retrieving the active components and the corresponding target information of each component in Xiaoyong Sanjie Formula with Pharmacology Database and Analysis Platform of Chinese Medicine System (TCMSP), and NPM-related genes in database like GeneCard, OMIM, PharmGkb, TTD, and DrugBank, the data of the core targets of Xiaoyong Sanjie Formula and disease-related genes was compared to obtain intersecting genes, and the STRING database was used to analyze the protein interaction network and find the core genes. With the help of Cytoscape 3.8.0, the active ingredient-target-pathway regulation network diagram of Xiaoyong Sanjie Formula for the treatment of NPM was established. The R language pack was used to enrich the targets with GO function and KEGG pathway enrichment, and the potential targets and mechanism of Xiaoyong Sanjie Formula in the treatment of NPM were explored. Finally, molecular docking verification was carried out to analyze the effecacy of key components and potential core targets of Xiaoyong Sanjie Formula.Results:Network pharmacological analysis showed that there were 47 active component and 1 692 NPM-related potential targets in Xiaoyong Sanjie Formula, and 235 core targets of NPM in the treatment of Xiaoyong Sanjie Formula. The key components of Xiaoyong Sanjie Formula in the treatment of NPM include Quercetin, Naringenin, Kaempferol, Diosgenin, Luteolin, etc., with the core targets of intercellular adhesion molecule-1 (ICAM-1), vascular endothelial growth factor (VEGFA), tumor necrosis factor (TNF), interleukin-6 (IL-6), Epidermal growth factor receptor (EGFR), interleukin-1β (IL-1B), chemokine-8 (CXCL8), chemokine-2 (CCL2), etc. GO enrichment obtained 1 492 biological process entries. The KEGG pathway is enriched to obtain 105 pathways, including the TNF signaling pathway, the PI3K-Akt signaling pathway, the NF-kappa B signaling pathway, and the JAK-STAT signaling pathway, IL-17 signaling pathway, C-type lectin receptor signaling pathway, etc. The final molecular docking verified that the key active ingredients of Xiaoyong Sanjie Formula could bind with the potential core targets closely.Conclusion:Xiaoyong Sanjie Formula can treat NPM with multi-component, multi-target characteristics,which plays a role of treating NPM through signaling pathways such as immuno-inflammatory response, the metabolism of the medicine, cellular adaptive stress response, and vascular function regulation.

Reversible cerebral vasoconstriction syndrome characterized by postpartum headache: a case report / 中华围产医学杂志

We report the diagnosis and treatment of a case of reversible cerebral vasoconstriction syndrome characterized by postpartum thunderclap headache. The patient experienced a thunderclap headache on the second day after delivery, which gradually worsened. On postpartum day 4, she presented with sudden convulsion and hypertension on admission on May 19, 2020, and was initially diagnosed with postpartum eclampsia. We confirmed the diagnosis of reversible cerebral vasoconstriction syndrome based on the results of cranial magnetic resonance angiography (MRA) and other examinations and the consultation with neurologists. After antihypertensive and spasmolytic treatment, the patient's blood pressure returned to normal, and she was discharged on postpartum day 8. Reexamination with cranial MRA at 50 + days after delivery indicated that the cerebral vasospasm was relieved. No severe headaches or convulsions were observed during follow-up till June 2021.

Social networking and help-seeking behaviors in relation to the health of pregnant and puerperal Brazilian women in Japan / 国際保健医療

  Introduction  This study aimed to clarify social networking and help seeking behaviors in relation to the health of pregnant and puerperal Brazilian women in Japan, using unanalyzed data collected in the article titled “Socio-cultural factors affecting the health of pregnant and puerperal Brazilian women in Japan” published in this journal.Methods  We conducted semi-structured interviews of pregnant and puerperal Brazilian women aged ≥20 years in their homes in Prefectures A and B during 2013-2014. We used the Japanese version of the interview guide based on the cultural determinants of help seeking developed by Arnault. The analysis was guided by analytic ethnography, and core themes were derived.Results  The interviews were conducted with 18 women. Their mean age was 32.4 years (5 women in their 20s and 13 women in their 30s). The average length of stay was 12.6 years (6 women: <10 years and 12 women: ≥10 years). Regarding residential status, 12 women were permanent residents. Two categories for social networking were derived: (1) limited social interaction and (2) reliance on family and trusted others. Two categories for help-seeking behaviors were derived: (1) reliance on informal resources close to them and (2) self-reliant problem solving.Conclusions  The social networking and help-seeking behaviors of pregnant and puerperal Brazilian women in Japan were related to their way of cultivating relationships in their transnational life as migrant workers. Their behaviors were also related to their perception on the family, their religion, and their self-reliant problem-solving behaviors.

Fascitis necrotizante por Enterococcus gallinarum en una puérpera. Presentación de un caso / Necrotizing fasciitis due to Enterococcus gallinarum in a pospartum patient. Case report

RESUMEN Fundamento: La fascitis necrotizante es una infección que se desarrolla de manera rápida, afecta la piel, tejido celular subcutáneo, fascia superficial y en ocasiones la profunda, en heridas quirúrgicas al producir necrosis hística y severa toxicidad sistémica. Es una afectación sistémica acompañante, que a su vez a ella se asocian factores predisponentes endógenos como: diabetes mellitus, obesidad, alcoholismo, infección por VIH, y exógenos: cirugía ginecobstétrica, inyecciones, traumatismos; por lo que estos pacientes resultan ser enfermos críticos en las unidades de cuidados intensivos, con un curso clínico no uniforme, al llevar a una evolución fulminante cuando corresponde con la variante hiperaguda o fulminante. Objetivo: Describir la presencia de fascitis necrotizante hiperaguda causada por Enterococcus gallinarum, en una puérpera. Reporte de caso: Puérpera que se le practicó parto distócico por cesárea electiva a las 38.3 semanas, a las 24 h presentó manifestaciones generales que se acompañaron de lesiones en la piel; se le realizó cirugía ginecobstétrica, su evolución fue tórpida y falleció por fallo multiorgánico a los 3 días debido a las consecuencias de fascitis necrotizante hiperaguda o fulminante, causada esta por un Enterococcus gallinarum. Conclusiones: La fascitis necrotizante es una enfermedad poco frecuente y mortal si no se trata a tiempo; su diagnóstico resulta difícil en su fase inicial, debido a que casi siempre es clínico. El tratamiento quirúrgico debe ser urgente, combinarse este con antibióticoterapia sistémica, debido al germen causal y la toxicidad que producen.

ABSTRACT Background: Necrotizing fasciitis is an infection that develops rapidly, affecting the skin, subcutaneous cellular tissue, superficial fascia and sometimes deep fascia, in surgical wounds by producing hystenotic necrosis and severe systemic toxicity. It is a supplementary systemic affectation, which in turn is associated with endogenous predisposing factors such as: diabetes mellitus, obesity, alcoholism, HIV infection, and exogenous: gynecobstetric surgery, injections, traumatisms; so these patients are critical patients in intensive care units, with a non-uniform clinical progression, leading to a fulminant evolution when parallel to the hyperacute or fulminant variant. Objective: To describe the presence of hyperacute necrotizing fasciitis caused by Enterococcus gallinarum in a puerperal. Case report: A puerperal who suffered from dystocia delivery by elective cesarean section at 38.3 weeks, at 24 h presented general manifestations accompanied by skin lesions; she underwent gynecobstetric surgery, her evolution was torpid and she died of multiorgan failure after 3 days due to the consequences of hyperacute or fulminant necrotizing fasciitis, caused by Enterococcus gallinarum. Conclusions: Necrotizing fasciitis is a rare and fatal disease if not treated in time; its diagnosis is difficult in its early phase because it is often clinical. Surgical treatment should be urgent and combined with systemic antibiotic therapy due to the causative germ and the toxicity they produce.

Factores asociados a anemia en post-cesareadas con y sin COVID-19 en el Hospital Nacional Alberto Sabogal Sologuren

Objetivo. Conocer los factores intrínsecos y extrínsecos asociados a anemia en pacientes post-operadas atendidas en las áreas de obstetricia COVID-19 y no COVID-19, del Hospital Nacional Alberto Sabogal Sologuren, EsSalud. Métodos. El estudio fue observacional, retrospectivo y transversal, enfoque cuantitativo, nivel explicativo, de modelo caso control, aplicado a 358 puérperas; de las cuales 179 fueron los casos, es decir aquellas puérperas con anemia en el post parto y 179 los controles, tomados de ambas áreas. Los datos fueron procesados con el estadístico SPSS 25. Resultados. Los factores intrínsecos: alimentación sin variación, sobrepeso u obesidad mórbida, paridad de 4 a más, número de cesáreas de 3 a más, y el periodo intergenésico menor de 2 años, fueron condiciones que representaron riesgo doble de producir anemia en el puerperio entre las mujeres del estudio, en relación a las que no tuvieron estas características. Además, el factor intrínseco o condición de haber tenido anemia durante el embarazo, resultó en una probabilidad 5 veces mayor a producir anemia en el puerperio entre las mujeres del estudio (Odds Ratio 5,156), en comparación a las mujeres que no tuvieron anemia. La ingesta de ácido fólico tuvo una probabilidad 3,4 veces menor (Odds Ratio de 3,408) de desarrollar la anemia respecto de aquellas que no lo hicieron y las complicaciones en el puerperio inmediato (Odds Ratio de 3,397) estuvieron asociados a la anemia en puérperas. Conclusiones. Los factores intrínsecos como el diagnóstico de anemia durante el embarazo y los factores extrínsecos como la no ingesta de ácido fólico y complicaciones en el puerperio inmediato, estuvieron asociados a la anemia en puérperas en el área de obstetricia COVID-19 y no COVID-19 del Hospital Alberto Sabogal.

Objective. To know the intrinsic and extrinsic factors associated with anemia in post-cesarean women treated in the COVID-19 and non-COVID-19 obstetric area of the Alberto Sabogal Hospital. Methods. The study was observational, retrospective and cross-sectional, quantitative approach, explanatory level, case- control model, applied to 358 puerperal women; of which 179 were the cases, that is, those puerperal women with postpartum anemia and 179 were controls, taken from both areas. The data were processed with the SPSS 25 statistic. Results. The intrinsic factors: diet without variation, overweight or morbid obesity, parity of 4 or more, number of cesarean sections of 3 or more, and the intergenetic period of less than 2 years, were conditions that represented a double risk of producing anemia in the puerperium among women in the study, in relation to those who did not have these characteristics. Also, the intrinsic factor or condition of having had anemia during pregnancy, resulted in a 5 times greater probability of producing anemia in the puerperium among the women in the study (Odds Ratio 5.156), compared to the women who did not have anemia. Folic acid intake was 3.4 times less likely (Odds Ratio of 3.408) to develop anemia compared to those who did not, and complications in the immediate puerperium (Odds Ratio of 3.397) were associated with anemia in puerperal women. Conclusions. Intrinsic factors such as the diagnosis of anemia during pregnancy and extrinsic factors such as folic acid not ingest and complications in the immediate puerperium were associated with anemia in puerperal women in the COVID-19 and non-COVID-19 obstetric area of Hospital Alberto Sabogal.

Use of CentriMag for refractory cardiogenic shock in a puerperal woman: case report

ABSTRACT CONTEXT: Heart failure in Brazil is a major public health problem and, even with advances in treatment, it still presents high morbidity and mortality. As a treatment option, mechanical circulatory assist devices (MCADs) have greatly increased in importance over the last decade. CASE REPORT: This report concerns a case of refractory cardiogenic shock due to acute myocarditis in a 35-year-old puerperal female patient who presented with retrosternal pain, fatigue and dyspnea. At the hospital, she was diagnosed with myocarditis. There was no improvement in perfusion even after receiving dobutamine, intra-aortic balloon passage (IAB) and venoarterial extracorporeal membrane oxygenation (VA-ECMO). Therefore, it was decided to implant a MCAD (CentriMag). During hospitalization, recovery from the bi-ventricular dysfunction was achieved. The CentriMag device was removed 10 days after it had been implanted, and the patient was discharged after another 8 days. The myocarditis was proven to be due to the Coxsackie virus. CONCLUSIONS: The decision to implant a MCAD should be individualized, as patient profiles do not always match the indications in the guidelines and protocols. In this study, clinical discussion of the case among the medical and multi-professional teams was essential in order to be able to successfully reverse the patient's severe clinical condition without sequelae, through using a CentriMag implant.

A propósito de un caso: presentación atípica de rotura uterina / A case report: unusual presentation of uterine rupture

RESUMEN La rotura del útero gestante se define como una solución de continuidad patológica de la pared uterina, situada con mayor frecuencia en el segmento inferior. La rotura de un útero intacto es muy rara, su incidencia está estimada entre 1/5700 y 1/20000 embarazos. Su prevalencia ha aumentado dado el incremento de parto vaginal con cesárea anterior. Actualmente oscila entre el 0.3 y el 1 %, siendo mayor en mujeres en las que tiene lugar un intento de parto vaginal tras cesárea (0,78%) que en aquellas en las que se lleva a cabo una cesárea electiva (0,22%). En cuanto a su diagnóstico, suele ser precoz, dada la clínica de gravedad con la que debutan. En este caso se presenta una evolución atípica de rotura uterina, donde la paciente se mantiene asintomática hasta que acude a urgencias cinco días después del parto con fiebre y dolor abdominal; gracias a la ecografía abdominal y trans-vaginal se pudo establecer rápidamente el diagnóstico y así proceder a su inmediata reparación quirúrgica.

ABSTRACT Rupture of the pregnant uterus is defined as a solution of pathological continuity of the uterine wall, most often located in the lower segment. The rupture of an intact uterus is very rare, its incidence is estimated between 1/5700 and 1/20000 pregnancies. Its prevalence has increased given the increase in vaginal delivery with previous caesarean section. Currently, it ranges between 0.3 and 1%, being higher in women with a vaginal delivery after caesarean section (0.78%) than in those who undergo an elective caesarean section (0.22%). Their diagnosis is usually early given by the severity of the debut. In this case, there is an atypical evolution of uterine rupture where the patient remains asymptomatic until she goes to the emergency room five days after delivery with fever and abdominal pain; Because of the abdominal and transvaginal ultrasound, the diagnosis could be quickly established and thus proceed to immediate surgical repair.

Peripartum Hysterectomies over a Fifteen-year Period / Histerectomias periparto ao longo de um período de quinze anos

Abstract Objective To determine the indications and outcomes of peripartum hysterectomies performed at Hospital de Clínicas de Porto Alegre (a university hospital in Southern Brazil) during the past 15 years, and to analyze the clinical characteristics of the women submitted to this procedure. Methods A cross-sectional study of 47 peripartum hysterectomies from 2005 to 2019. Results The peripartum hysterectomies performed in our hospital were indicated mainly due to placenta accreta or suspicion thereof (44.7% of the cases), puerperal hemorrhage without placenta accreta (27.7%), and infection (25.5%). Total hysterectomies accounted for 63.8% of the cases, andwefound no differencebetween total versus subtotal hysterectomies in the studied outcomes. Most hysterectomies were performed within 24 hours after delivery, and they were associated with placenta accreta, placenta previa, and older maternal age. Conclusion Most (66.0%) patients were admitted to the intensive care unit (ICU). Those who did not need it were significantly older, and had more placenta accreta, placenta previa, or previous Cesarean delivery.

Resumo Objetivo Determinar as indicações e os desfechos das histerectomias periparto realizadas no Hospital de Clínicas de Porto Alegre nos últimos 15 anos, bem como analisar as características clínicas das mulheres submetidas a esse procedimento. Métodos Estudo transversal de 47 histerectomias periparto realizadas no período de 2005 a 2019. Resultados Em nosso hospital, as histerectomias periparto foram indicadas principalmente por acretismo placentário ou sua suspeita (44,7% dos casos), hemorragia puerperal sem acretismo placentário (27,7%), e infecção (25,5%). Histerectomias totais corresponderam a 63,8% dos casos, e não encontramos diferença entre histerectomia total e subtotal para os desfechos estudados. Amaioria das histerectomias foi realizada dentro de 24 horas após o parto, o que estava associado a acretismo placentário, placenta prévia, e idade materna mais avançada. Conclusão A maioria (66,0%) das mulheres necessitou de internação em unidade de terapia intensiva (UTI); aquelas que não necessitaram eram significativamente mais velhas, e tinham mais acretismo placentário, placenta prévia, ou cesárea prévia.

O imaginário materno sobre os partos cesáreo e vaginal / The maternal imagery on cesarean and vaginal deliveries / El imaginario materno sobre los partos cesáreo y vaginal

Este artigo objetivou compreender o imaginário materno sobre os partos cesáreo e vaginal. Para isso, utilizou-se de revisão da literatura e entrevista semi-estruturada com quatro gestantes participantes do Grupo de Gestantes de uma maternidade pública de Goiânia. Os dados foram tratados pela análise de conteúdo e mostraram uma visão mais positiva sobre a via vaginal em contraposição ao cirúrgico, que se relacionou à intercorrência. Além disso, o imaginário das participantes se mostrou em grande parte permeado por sentimentos e ideias negativas como medo, ansiedade e preocupação sobre ambos os partos. As principais informações que baseiam as concepções das gestantes partem das experiências passadas por outras mulheres e não dos conhecimentos médicos, de modo que são constituídas principalmente por histórias de violência, dor e desrespeito. Conclui-se que o imaginário materno, formado a partir do contexto atual de saúde, compreende o parto como um evento temido, que se desejaria evitar. Percebe-se que a assistência em saúde prestada hoje ainda é insuficiente por não orientar corretamente a mulher e dificultar que ela domine a cena do parto, o que a deixa à margem da humanização. Ademais, o cuidado terapêutico voltado à mulher não se pauta na opinião e nos sentimentos da paciente para embasar sua atuação, o que de certa forma contribui para manutenção do imaginário negativo sobre parto e demanda maior empenho em relação às práticas e à educação permanente.(AU)

This article sought to understand the maternal imaginary on cesarean and vaginal deliveries. Data were collected by means of a literature review and semi-structured interviews conducted with four pregnant women, participants of the Group of Pregnant Women in a public maternity hospital in Goiânia, and treated by content analysis. The results indicate that mothers tend to have a more positive view of the vaginal route, associating surgical deliveries to pregnancy complications. Being mostly informed by the experiences of other women rather than by medical knowledge, and thus influenced by stories of violence, pain, and disrespect, the imagery of participants proved to be largely permeated by negative feelings and ideas about both types of birth, such as fear, anxiety, and concern. Thus, in the current health context, the maternal imaginary understands childbirth as a feared event, which one would want to avoid. This finding highlights the inappropriate healthcare provided to pregnant women, failing in properly guiding and preventing them from controlling the delivery scene, being left on the margins of humanization. This is because the therapeutic care aimed at women is not based on the patient's opinion and feelings, thus contributing to the maintenance of this negative imagery about childbirth and demanding greater commitment in relation to practices and permanent education.(AU)

Este artículo tuvo como objetivo comprender el imaginario materno sobre cesáreas y partos vaginales. Para eso, se hace una revisión de la literatura y una entrevista semiestructurada con cuatro mujeres embarazadas, participantes del Grupo de Mujeres Embarazadas en un hospital público de maternidad en Goiânia (Brasil). En los datos obtenidos se aplicaron análisis de contenido en que se reveló una visión más positiva de la ruta vaginal en comparación con la quirúrgica relacionada con la complicación. Además, en el imaginario de las participantes figuran sentimientos e ideas negativas como el miedo, la ansiedad y la preocupación por ambos tipos de parto. La información principal que respalda las concepciones de las mujeres embarazadas proviene de las experiencias transmitidas por otras mujeres, y no del conocimiento médico, que consiste principalmente en historias de violencia, dolor y falta de respeto. Se concluye que el imaginario materno, formado a partir del contexto de salud actual, entiende el parto como un evento temido, que hubieran querido evitar. Está claro que la atención médica brindada hoy en día aún es insuficiente porque no guía correctamente a las mujeres y les impide dominar la escena del parto, dejándolas al margen de la humanización. Se percibe que la atención terapéutica dirigida a las mujeres no se basa en su opinión y sentimiento para respaldar el desempeño, lo que de cierta manera contribuye al mantenimiento de esta imagen negativa sobre el parto y exige un mayor compromiso en relación con las prácticas y la educación permanente.(AU)

Analysis of early and late maternal complications associated with delivery using propensity score / Análise das complicações maternas precoces e tardias associadas à via de parto utilizando escore de propensão

ABSTRACT: Objective: To analyze early and late maternal complications associated with the mode of delivery in a birth cohort in Brazil, using the propensity score technique for analysis. Methods: This is a prospective cohort study, using data from the Pelotas Birth Cohort, RS, 2004. A total of 4,189 women were included and a descriptive analysis of the data and subsequent calculation of the propensity and pairing score of vaginal delivery women and cesarean delivery women with similar scores (1,366 pairs). We then assessed the difference in outcome risk between the groups. Results: Women in the cesarean group had 2.9 percentage points (pp) more risk of postpartum infection, 1.13 p.p. more risk of urinary infection, 1.10 p.p. more risk of anesthetic complications and 1.24 p.p. higher risk of headache compared to vaginal delivery, but less risk of anemia (-2.43 pp) and hemorrhoids (-1.24 p.p.). The use of propensity scores is extremely useful for reducing bias and increasing accuracy in observational studies when experimental studies cannot be performed. Conclusion: Cesarean sections have been associated with a higher prevalence of postpartum and urinary tract infections, anesthetic complications and headache and lower prevalence of anemia and hemorrhoids, so they should be performed with clear indications and when their benefits outweigh potential risks.

RESUMO: Objetivo: Analisar as complicações maternas precoces e tardias, associadas à via de parto, em uma coorte de nascimentos no Brasil, utilizando para a análise a técnica de escores de propensão. Métodos: Trata-se de estudo do tipo coorte prospectiva, utilizando dados da Coorte de Nascimentos de Pelotas (RS), de 2004. Incluíram-se 4.189 mulheres, e realizaram-se análise descritiva dos dados e posterior cálculo do escore de propensão e pareamento das mulheres de parto vaginal com as mulheres de parto cesárea com escores semelhantes (1.366 pares), avaliando a diferença no risco do desfecho entre os grupos. Resultados: As mulheres do grupo cesárea apresentaram 2,9 pontos percentuais (p.p.) a mais de risco de infecção pós-parto, 1,13 p.p. a mais de risco de infecção urinária, 1,10 p.p. a mais de risco de complicações anestésicas e 1,24 p.p. a mais de risco de cefaleia que as de parto vaginal, porém apresentaram menor risco de anemia (-2,43 p.p.) e hemorroidas (-1,24 p.p.). A utilização de escores de propensão é extremamente útil para a redução de vieses e o aumento da precisão em estudos observacionais, quando estudos experimentais não podem ser realizados. Conclusão: As cesáreas associaram-se a maiores prevalências de infecções pós-parto e urinária, complicações anestésicas e cefaleia e menores prevalências de anemia e hemorroidas, portanto devem ser realizadas com indicações claras e quando seus benefícios superam potenciais riscos.

Infecção do sítio cirúrgico após cesariana em uma maternidade de Manaus, Brasil: a importância do uso racional da antibioticoterapia / Surgical site infection after cesarean section in a maternity hospital in Manaus, Brazil: the importance of rational antibiotic therapy

Objetivo: Descrever o perfil epidemiológico e microbiológico das puérperas com diagnóstico de infecção após cesárea, caracterizando as infecções de sítio cirúrgico e o tratamento. Métodos: Coorte prospectiva de parturientes submetidas a parto cesáreo em maternidade pública de Manaus, Amazonas, Brasil, com diagnóstico de infecção de sítio cirúrgico, entre 1º de julho de 2019 e 30 de abril de 2020. Foram coletados dados epidemiológicos. Para a investigação do perfil microbiológico, foi realizada a identificação da cultura a partir da secreção da infecção do sítio cirúrgico e do antibiograma das culturas. Resultados: Um total de 81 pacientes foi diagnosticado com infecção de sítio cirúrgico durante o período de estudo. A taxa de infecção de sítio cirúrgico na maternidade em estudo foi de 6,0%. As pacientes possuíam baixa escolaridade e baixa renda mensal, com ocupações que requerem menor qualificação, sendo a maioria solteira. Entre as pacientes, 70,4% eram obesas e 28,4% apresentaram sobrepeso; 45,6% delas tiveram parto cesáreo de emergência e 29,6% não usaram antibióticos profiláticos. Staphylococcus aureus foi a cultura identificada mais frequentemente e apresentou resistência ao antibiótico mais prescrito: a gentamicina. Conclusão: A taxa de infecção do sítio cirúrgico foi alta durante o período do estudo. Ressaltamos a necessidade de um protocolo eficaz de identificação bacteriana e acompanhamento da puérpera. O conhecimento das características epidemiológicas e microbiológicas pode auxiliar no planejamento dos cuidados realizados pelas instituições de saúde para minimizar os casos de infecção de sítio cirúrgico e suas consequências.(AU)

Objective: To describe the epidemiological and microbiological profiles of puerperal women diagnosed with the infection after cesarean sections, characterizing the surgical site infections and treatment. Methods: Prospective cohort of parturients underwent cesarean delivery at a public maternity hospital in Manaus, Amazonas, Brazil, diagnosed with surgical site infection between July 1, 2019, and April 30, 2020. Epidemiological data were collected. To investigate the microbiological profile, both culture identification from surgical site infection secretion and antibiogram for the cultures were performed. Results: A total of 81 patients were confirmed to have surgical site infection during this study period; The surgical site infection rate in the maternity hospital under study was 6.0%. The patients presented a low level of education and monthly income, with occupations that require lower qualification, and most of them are single. Seventy point four percent of the patients were obese, and 28.4% were overweight. Forty-five point six percent of patients had an emergency cesarean delivery, and 29.6% did not use prophylactic antibiotics. Staphylococcus aureus was the most frequent culture identified from surgical site infection secretion and presented resistance to the most prescribed antibiotic, Gentamicin. Conclusion: The rate of surgical site infection was high during the study period. We highlight the need for an effective bacterial identification protocol and monitoring of puerperal women. Knowledge of epidemiological and microbiological characteristics can assist in the planning of care performed by the health institutions to minimize cases of surgical site infection and its consequences.(AU)
