RESUMEN

Lactational mastitis, a common condition affecting nursing mothers, is characterized by mammary gland inflammation during lactation. This inflammatory response typically occurs due to bacterial infection. The discomfort and pain associated with lactational mastitis can significantly impact a mother's ability to breastfeed comfortably and may lead to the cessation of breastfeeding altogether if left untreated. Antibiotics are commonly prescribed to target the bacteria causing the infection and alleviate symptoms, aiming to treat the infection. Nevertheless, a notable worry linked to antibiotic use is the emergence of antibiotic resistance, compounded by the possible persistence of antibiotics in milk. Additionally, lactational mastitis is characterized by its polymicrobial nature. In this study, bacteria were isolated from infected breast milk samples and whole-genome sequencing was performed on eleven isolates to accurately identify the bacteria and assess their antibiotic resistance profiles. Using Galaxy tools and the ResFinder database, we identified Bacillus paraanthracis, Bacillus altitudinis, Staphylococcus aureus, Bacillus cereus, Escherichia coli, Alcaligenes faecalis, and Bacillus licheniformis, along with antibiotic-resistant genes like fosB1, cat86, erm (D), blaZ, and mdf (A). ABRicate aided in antimicrobial resistance (AMR) gene analysis, and CARD visualized their distribution. Our study demonstrates that the severity of infection is directly proportional to an increase in somatic cell count (SCC). This research sheds light on microbial diversity in lactational mastitis milk and provides crucial insights into antibiotic-resistance genes. Utilizing bioinformatics tools, such as those employed in this study, can inform the design of effective treatment strategies for lactational mastitis infections.

RESUMEN

Introduction: Globally, oral health diseases surpass all other non-communicable diseases in prevalence; however, they are not well studied in underserved regions, where accessibility to dental services and oral health education is disparately worse. In Ecuador, further research is needed to understand such disparities better. We aimed to assess the effect of oral health disease on individuals' quality of life and how social disparities and cultural beliefs shape this. Methods: Individuals 18 or older receiving care at mobile or worksite clinics from May to October 2023 were included. A mixed-methods approach was employed, involving semi-structured interviews, Oral Health-Related Quality of Life (OHRQoL) measures, and extra-oral photographs (EOP). Results: The sample (n = 528) included mostly females (56.25%) with a mean age of 34.4 ± 9.44. Most participants (88.26%) reported brushing at least twice daily, and less than 5% reported flossing at least once per day. The median OHRQoL score was 4 (min-max), significantly higher among individuals ≥40 years old, holding high school degrees, or not brushing or flossing regularly (p < 0.05). Identified barriers to good oral health included affordability, time, and forgetfulness. Participants not receiving care with a consistent provider reported fear as an additional barrier. Participants receiving worksite dental services reported these barriers to be alleviated. Dental providers were the primary source of oral hygiene education. Most participants reported oral health concerns, most commonly pain, decay, dysphagia, and halitosis - consistent with EOP analysis. Discussion: Findings underscore a need for multi-level interventions to advance oral health equity.

RESUMEN

Curcumin serves as a photosensitizer (PS) in the context of microbial inactivation when subjected to light exposure, to produce reactive oxygen species, which exhibit efficacy in eradicating microorganisms. This remarkable property underscores the growing potential of antimicrobial photodynamic therapy (aPDT) in the ongoing fight against bacterial infections. Considering this, we investigate the efficacy of various in vitro curcumin formulations within a PDT protocol designed to target Staphylococcus aureus. Specifically, we conduct a comparative analysis involving synthetic curcumin (Cur-Syn) and curcumin derivatives modified with chlorine (Cl), selenium (Se), and iodine (I) (Cur-Cl, Cur-Se, Cur-I). To assess the impact of aPDT, we subject S. aureus to incubation with curcumin, followed by irradiation at 450 nm with energy doses of 3.75, 7.5, and 15 J/cm2. Our investigation encompasses an evaluation of PS uptake and photobleaching across the various curcumin variants. Notably, all three modifications (Cur-Cl, Cur-Se, Cur-I) induce a significant reduction in bacterial viability, approximately achieving a 3-log reduction. Interestingly, the uptake kinetics of Cur-Syn and Cur-Se exhibit similarities, reaching saturation after 20 min. Our findings suggest that modifications to curcumin have a discernible impact on the photodynamic properties of the PS molecule.

RESUMEN

BACKGROUND: Colorectal carcinoma (CRC) is one of the common carcinomas with a rising incidence of metastasis due to its advanced stage of presentation. The existing biomarkers such as CEA (Carcinoembryonic antigen) etc., for prognosis, have low sensitivity and specificity. Hence a need for a newer definitive biomarker. Obesity is the leading cause of CRC. Leptin and adiponectin secreted by adipose tissue have been studied as potential biomarkers in the field of CRC. The present study helps to understand the association of leptin and adiponectin receptors with clinicopathological parameters. OBJECTIVE: To correlate the various clinicopathological parameters with the tissue expression of leptin and adiponectin receptors in CRC. METHODS: It is a cross-sectional prospective study conducted at a tertiary care hospital. Formalin fixed paraffin blocks of all radical resection CRC cases were collected and immunohistochemistry (IHC)was carried out on tumor tissue for leptin and adiponectin receptor. Tumor characteristics and clinical parameters were collected from the hospital medical records. Pearson's correlation coefficient test was used. RESULTS: Immunohistochemistry was performed on 60 cases of CRC. Significant positive correlation of leptin was observed with size, lymph node metastasis, advanced stage, and grade of tumor (P<0.05). A significant correlation between adiponectin receptor and CRC was observed concerning age, stage, lymph node metastasis, distant metastasis and grade of tumor. CONCLUSION: Positive expression of leptin and negative expression of adiponectin receptors in CRC helps to predict the risk of metastasis.

RESUMEN

Introduction: Sexually transmitted infections (STIs) pose a significant public health challenge in contemporary society, exacerbated by evolving sexual behaviors and societal shifts. Despite advancements in medical science, the prevalence of STIs continues to rise, necessitating a multifaceted approach to combat this epidemic. This opinion article examines the prospect of addressing the surge in STIs through a comprehensive strategy that encompasses educational reforms, destigmatization efforts, enhanced resource accessibility, and technological innovations. Objective: The primary objective of this article is to underscore the urgency of implementing a comprehensive approach to combat the escalating rates of STIs. By elucidating the limitations of existing educational frameworks and societal attitudes towards STIs, this article seeks to advocate for transformative measures that bridge the educational gap and foster a more informed and empowered populace capable of preventing and managing STIs effectively. Methods: This opinion piece is based on existing literature on STIs, educational strategies, and public health interventions to formulate a comprehensive approach to addressing the STI epidemic. Drawing upon empirical evidence and expert opinions, the article identifies key areas for intervention and proposes actionable recommendations for stakeholders, including policymakers, educators, healthcare providers, and community leaders. Results: The analysis underscores the pressing need for a paradigm shift in STI education and prevention efforts. Current educational modalities often fail to resonate with modern sexual behaviors and perpetuate the stigma surrounding STIs, impeding effective prevention and treatment initiatives. By adopting a comprehensive approach that integrates accurate information, destigmatization campaigns, enhanced access to resources, and innovative technologies, significant strides can be made in curbing the spread of STIs and promoting sexual health and well-being. Conclusion: In conclusion, combating the surge in STIs demands a concerted effort to bridge the educational gap and address the root causes of the epidemic. By embracing a comprehensive approach that acknowledges the complexities of modern sexuality, destigmatizes STIs, and empowers individuals with knowledge and resources, we can pave the way toward a healthier and more sexually literate society. Policymakers, healthcare professionals, educators, and community stakeholders must collaborate to enact meaningful change and mitigate the profound impact of STIs on public health and well-being.

Introdução: As infecções sexualmente transmissíveis (IST) representam um desafio significativo de saúde pública na sociedade contemporânea, exacerbado pela evolução dos comportamentos sexuais e pelas mudanças sociais. Apesar dos avanços na ciência médica, a prevalência de IST continua a aumentar, havendo necessidade de uma abordagem multifacetada para combater esta epidemia. Este artigo de opinião examina a perspectiva de abordar o aumento das IST por meio de uma estratégia abrangente, que engloba reformas educativas, esforços de desestigmatização, maior acessibilidade aos recursos e inovações tecnológicas. Objetivo: O objetivo principal deste artigo é sublinhar a urgência de implementar uma abordagem abrangente para combater as taxas crescentes de IST. Ao elucidar as limitações dos quadros educativos existentes e das atitudes da sociedade em relação às IST, este artigo procura defender medidas transformadoras que colmatem a lacuna educacional e promovam uma população mais informada e capacitada, capaz de prevenir e gerir eficazmente as IST. Métodos: Este artigo de opinião baseia-se na literatura existente sobre IST, estratégias educativas e intervenções de saúde pública para formular uma abordagem abrangente para enfrentar a epidemia de IST. Com base em evidências empíricas e opiniões de especialistas, o artigo identifica áreas-chave de intervenção e propõe recomendações práticas para as partes interessadas, incluindo decisores políticos, educadores, prestadores de cuidados de saúde e líderes comunitários. Resultados: A análise sublinha a necessidade premente de uma mudança de paradigma na educação e nos esforços de prevenção das IST. As atuais modalidades educativas, muitas vezes, não conseguem repercutir nos comportamentos sexuais modernos e perpetuam o estigma em torno das IST, impedindo iniciativas eficazes de prevenção e tratamento. Ao adotar uma abordagem abrangente que integre informações precisas, campanhas de desestigmatização, maior acesso aos recursos e tecnologias inovadoras, podem ser feitos avanços significativos na contenção da propagação das IST e na promoção da saúde sexual e do bem-estar. Conclusão:Em conclusão, o combate ao aumento das IST exige um esforço concertado para colmatar o fosso educativo e abordar as causas profundas da epidemia. Ao adotarmos uma abordagem abrangente que reconheça as complexidades da sexualidade moderna, desestigmatize as IST e capacite os indivíduos com conhecimentos e recursos, podemos preparar o caminho para uma sociedade mais saudável e com maior literacia sexual. Os decisores políticos, os profissionais de saúde, os educadores e as partes interessadas da comunidade devem colaborar para implementar mudanças significativas e mitigar o impacto profundo das IST na saúde pública e no bem-estar.

RESUMEN

OBJECTIVE: To compare brain magnetic resonance imaging (MRI) biomarkers and neurodevelopmental test scores in infants born preterm with and without prenatal opioid exposure (POE). STUDY DESIGN: We examined 395 preterm infants (≤32 weeks gestational age) who had term-equivalent brain MRIs, composite scores from the Bayley Scales of Infant and Toddler Development-III at 2 years corrected age, and POE data. MRI parameters included total/regional brain volumes and severe punctate white matter lesions (PWMLs). We conducted bivariable analysis and multivariable logistic regression analyses. RESULTS: The mean ± SD gestational age was 29.3 ± 2.5 weeks; 35 (8.9%) had POE and 20 (5.1%) had severe PWML. Compared with unexposed infants, those with POE exhibited higher rates of severe PWML (17.1% vs 3.9%, respectively; P = .002); findings remained significant with an OR of 4.16 (95% CI, 1.26-13.68) after adjusting for confounders. On mediation analysis, the significant relationship between POE and severe PWML was not indirectly mediated through preterm birth/gestational age (OR, 0.93; 95% CI, 0.78-1.10), thus suggesting the association was largely driven by a direct adverse effect of POE on white matter. In multivariable analyses, POE was associated with a significantly lower score by -6.2 (95% CI, -11.8 to -0.6) points on the Bayley Scales of Infant and Toddler Development-III Motor subscale compared with unexposed infants. CONCLUSIONS: POE was associated with severe PWML; this outcome may be a direct effect of POE rather than being mediated by premature birth. POE was also associated with worse motor development. Continued follow-up to understand the long-term effects of POE is warranted.

RESUMO Contexto: O carcinoma colorretal (CCR) é um dos carcinomas comuns com incidência crescente de metástases devido ao seu estágio avançado de apresentação. Os biomarcadores existentes como CEA (antígeno carcinoembrionário) etc., para prognóstico, apresentam baixa sensibilidade e especificidade. Daí a necessidade de um biomarcador definitivo mais recente. A obesidade é a principal causa do CCR. A leptina e a adiponectina secretadas pelo tecido adiposo têm sido estudadas como potenciais biomarcadores na área do CCR. O presente estudo ajuda a compreender a associação dos receptores de leptina e adiponectina com parâmetros clinicopatológicos. Objetivo: Correlacionar os diversos parâmetros clinicopatológicos com a expressão tecidual dos receptores de leptina e adiponectina no CCR. Métodos: Trata-se de um estudo transversal, prospectivo, realizado em um hospital terciário. Blocos de parafina fixados em formalina de todos os casos de CCR de ressecção radical foram coletados e a imuno-histoquímica (IHQ) foi realizada no tecido tumoral para receptor de leptina e adiponectina. As características do tumor e os parâmetros clínicos foram coletados dos prontuários médicos do hospital. Foi utilizado o teste do coeficiente de correlação de Pearson. Resultados: A imunohistoquímica foi realizada em 60 casos de CCR. Correlação positiva significativa da leptina foi observada com tamanho e metástase linfonodal, estágio avançado e grau do tumor (P<0,01). Foi observada uma correlação significativa entre o receptor de adiponectina e o CCR em relação à idade, estágio, metástase linfonodal, metástase à distância e grau do tumor. Conclusão: A expressão positiva de leptina e a expressão negativa de receptores de adiponectina no CCR ajudam a prever o risco de metástase.

RESUMEN

Balloon cell melanoma is a rare presentation of malignant melanoma, usually on the skin, with less than 100 cases reported. Mucosal BCM is even rarer, with only one case of anorectal BCM reported in English literature. The diagnosis is based on the histopathologic findings of a tumor composed of large, foamy melanocytes, with or without pigmentation, and confirmed by immunohistochemical studies showing expression for melanocytic markers. The foam cell appearance of the tumor cells and the lack of melanin pigment lead to a diagnostic dilemma, mostly when presented at an unusual location. Herein, we report a case of balloon cell melanoma at the anorectal junction in a 73-year-old male patient complaining of constipation and bleeding per rectum. Surgical resection was performed with no evidence of recurrence after three years of close follow-up. We believe this case will raise awareness among the medical community to consider this tumor a differential diagnosis in rectal masses.

RESUMEN

Abstract Objective: To evaluate the efficacy and safety of trans-nasal Sphenopalatine Ganglion (SPG) block over other treatments for Post-Dural Puncture Headache (PDPH) management. Methods: A systematic literature search was conducted on databases for Randomized Controlled Trials (RCTs) comparing trans-nasal SPG blockade for the management of PDPH over other treatment modalities. All outcomes were pooled using the Mantel-Haenszel method and random effect model. Analyses of all outcomes were performed as a subgroup based on the type of control interventions (conservative, intranasal lignocaine puffs, sham, and Greater Occipital Nerve [GON] block). The quality of evidence was assessed using the GRADE approach. Results: After screening 1748 relevant articles, 9 RCTs comparing SPG block with other interventions (6 conservative treatments, 1 sham, 1 GON and 1 intranasal lidocaine puff) were included in this meta-analysis. SPG block demonstrated superiority over conservative treatment in pain reduction at 30 min, 1 h, 2 h, 4 h after interventions and treatment failures with "very low" to "moderate" quality of evidence. The SPG block failed to demonstrate superiority over conservative treatment in pain reduction beyond 6 h, need for rescue treatment, and adverse events. SPG block demonstrated superiority over intranasal lignocaine puff in pain reduction at 30 min, 1 h, 6 h, and 24 h after interventions. SPG block did not show superiority or equivalence in all efficacy and safety outcomes as compared to sham and GON block. Conclusion: Very Low to moderate quality evidence suggests the superiority of SPG block over conservative treatment and lignocaine puff for short-term pain relief from PDPH. PROSPERO Registration: CRD42021291707.

RESUMEN

Abstract Dental age estimation is very important for individual identification in criminal and civil forensic investigations. One of the methods for age estimation is studying age related changes in pulp volume of teeth. The objective of the current study was to estimate dental age from the pulp volume of five different categories of teeth of a Peruvian sample using cone beam computed tomography (CBCT). Retrospective CBCT records of 231 patients (females (134), males (97), age: 12-60 years) were included in the study, categorized into five different age groups (12-19, 20-29, 30-39, 40-49, 50-59, 60 years and older). Dental pulp volume of five categories of teeth(upper canines, left upper central incisors, left upper first molars, lower left first premolars, first molars) were analyzed using Romexis® 5.3.3.5 software for each patient. There was a reduction in the pulp volume of upper right and left canine with age. The Pulp volume was lowest in people aged 60 years and over. Linear regression analysis of the pulp volume and chronological age showed a coefficient of determination of 30%, suggesting a weak correlation. A weak correlation between dental pulp and age is derived. But, a robust large homogenous sample of teeth in future for different age groups may establish a reliable regression equation.


Resumen La estimación de la edad dental en personas vivas y cadáveres es muy importante para la Odontología Forense, sobre todo en casos de identificación en investigaciones legales y sociales. El objetivo del estudio fue estimación de la edad dental mediante la medición del volumen pulpar de imágenes dentales en tomografía computarizada de haz cónico (TCHC) de pacientes peruanos. Fueron analizadas 231 TCHC de pacientes entre 12 a 60 años a más. (Mujeres (134), hombres (97)) se dividieron en seis grupos de edad (12-19, 20-29, 30-39, 40-49, 50-59, 60 años a más). El análisis volumétrico de la pulpa dental se realizó en un total de 1155 dientes (caninos superiores, incisivos centrales superiores izquierdos, primeros molares superiores izquierdos y primeros premolares inferiores izquierdos), mediante el software Romexis® 5.3.3.5. El análisis de regresión lineal mostró un coeficiente de determinación del 30% que sugiere una correlación débil entre la relación del volumen pulpar de los dientes y la edad. El volumen pulpar de los caninos superiores derecho e izquierdo disminuyó a medida que aumentaba la edad y el volumen pulpar en dientes de personas de 60 años a más fue el más bajo. Sin embargo, se pueden proponer estudios futuros para incluir una gran muestra homogénea de dientes en diferentes categorías y grupos de edad para confirmar la correlación y establecer una ecuación de regresión confiable.

RESUMEN

The objectives of this study were twofold: (1) to identify potential differences in the ruminal and fecal metabolite profiles of Nelore bulls under different nutritional interventions; and (2) to identify metabolites associated with cattle sustainability related-traits. We used different nutritional interventions in the feedlot: conventional (Conv; n = 26), and by-product (ByPr, n = 26). Thirty-eight ruminal fluid and 27 fecal metabolites were significantly different (P < 0.05) between the ByPr and Conv groups. Individual dry matter intake (DMI), residual feed intake (RFI), observed water intake (OWI), predicted water intake (WI), and residual water intake (RWI) phenotypes were lower (P < 0.05) in the Conv group, while the ByPr group exhibited lower methane emission (ME) (P < 0.05). Ruminal fluid dimethylamine was significantly associated (P < 0.05) with DMI, RFI, FE (feed efficiency), OWI and WI. Aspartate was associated (P < 0.05) with DMI, RFI, FE and WI. Fecal C22:1n9 was significantly associated with OWI and RWI (P < 0.05). Fatty acid C14:0 and hypoxanthine were significantly associated with DMI and RFI (P < 0.05). The results demonstrated that different nutritional interventions alter ruminal and fecal metabolites and provided new insights into the relationship of these metabolites with feed efficiency and water intake traits in Nelore bulls.

RESUMEN

PURPOSE: Timely radiation treatment (RT) is critical in cervical cancer treatment, but patients in low- and middle-income countries (LMICs) in sub-Saharan Africa often face barriers that delay care. Time to care was benchmarked in a multidisciplinary team (MDT) setting in Botswana. METHODS: Time intervals between steps in care were recorded for 230 patients reviewed at MDT between January 2016 and July 2018. Associations between RT delay and overall survival (OS) were evaluated using Kaplan-Meier curves and multivariable Cox proportional hazards models. RESULTS: For patients who received RT (n = 187; 81.3%), the median biopsy to pathology reporting interval was 25 (IQR, 19-36) days and was 57 (IQR, 28-68) days for patients who did not (P = .003). Intervals in care did not differ between patients who did and did not receive RT. Among treated patients, the uppermost quartile interval from pathology reporting to RT initiation was ≥111 days and that from RT simulation to initiation was ≥12 days. Among patients receiving a RT dose of ≥65 Gy (n = 100), the delay from RT simulation to initiation of >12 days was associated with worse median OS (2.0 v 4.6 years; P = .048); this association trended toward, although did not meet, statistical significance on multivariable analysis (hazard ratio, 2.35; 95% CI, 0.95 to 5.85; P = .07). CONCLUSION: The MDT-coordinated care model allows for systematic benchmarking of the patient treatment cascade. Barriers to timely treatment exist for this cohort in Botswana, and RT delay may be associated with OS of patients receiving curative treatment. Interventions to accelerate the timing of the radiation oncology care cascade may improve clinical outcomes in this LMIC setting.

RESUMEN

INTRODUCTION: Multimorbidity has emerged as a major healthcare challenge in low/middle-income countries (LMICs) such as India and Brazil. Life course epidemiology suggests that adverse events in early life contribute to an individual's later health in adulthood. However, little is known about the influence of early life health and social factors on the development of multimorbidity in adulthood in LMICs. We aimed to explore the association of adult multimorbidity with childhood health and social disadvantages among two LMICs, India and Brazil. METHODS: We conducted a secondary data analysis of older adults aged ≥50 years using nationally representative surveys from Longitudinal Ageing Study in India, 2017-2018 (n=51 481) and 'Estudo Longitudinal da Saude e Bem-Estar dos Idosos Brasileirous', 2015-2016 (n=8730). We estimated the prevalence of multimorbidity along with 95% CI as a measure of uncertainty for all weighted proportions. Log link in generalised linear model was used to assess the association between childhood health and disadvantages with multimorbidity, reported as adjusted prevalence ratio (APR). RESULTS: The prevalence of multimorbidity was 25.53% and 55.24% in India and Brazil, respectively. Participants who perceived their childhood health as poor and missed school for a month or more due to illness had the highest level of multimorbidity across both countries. After adjusting for age and gender, a significant association between adult multimorbidity and poor self-rated childhood health (APR: (India: 1.38, 1.16 to 1.65) and (Brazil: 1.19, 1.09 to 1.30)); and missed school for a month due to illness (AOR: (India: 1.73, 1.49 to 2.01) and (Brazil: 1.16, 1.08 to 1.25)) was observed. CONCLUSION: Early life health, educational and economic disadvantages are associated with adult multimorbidity and appear to contribute to the later course of life. A life course approach to the prevention of multimorbidity in adulthood in LMICs may be useful in health programmes and policies.

RESUMEN

Plant omics, which includes genomics, transcriptomics, metabolomics and proteomics, has played a remarkable role in the discovery of new genes and biomolecules that can be deployed for crop improvement. In wheat, great insights have been gleaned from the utilization of diverse omics approaches for both qualitative and quantitative traits. Especially, a combination of omics approaches has led to significant advances in gene discovery and pathway investigations and in deciphering the essential components of stress responses and yields. Recently, a Wheat Omics database has been developed for wheat which could be used by scientists for further accelerating functional genomics studies. In this review, we have discussed various omics technologies and platforms that have been used in wheat to enhance the understanding of the stress biology of the crop and the molecular mechanisms underlying stress tolerance.

RESUMEN

IMPORTANCE: Polypharmacy and multimorbidity are common in older adults but has not been well studied in the urogynecologic patient population. OBJECTIVES: The objective of this study was to determine the prevalence of polypharmacy and multimorbidity in a diverse outpatient urogynecologic population and to examine whether polypharmacy and/or multimorbidity were associated with lower urinary tract symptoms, pelvic organ prolapse, defecatory distress, and/or female sexual dysfunction. STUDY DESIGN: This is a secondary analysis of a dual-center cross-sectional study of new patients presenting for evaluation of pelvic floor disorders at 2 urban academic outpatient urogynecology clinics. Baseline demographics and clinical characteristics were obtained from the electronic medical record. Validated surveys were administered to determine severity of lower urinary tract symptoms (Overactive Bladder Validated 8-Question Screener, Urogenital Distress Inventory-6), pelvic floor dysfunction (Pelvic Organ Prolapse Distress Inventory-6, Colorectal-Anal Distress Inventory-8), and sexual dysfunction (6-item Female Sexual Function Index). Standard statistical techniques were used. RESULTS: One hundred ninety-seven women with mean age 58.8 years (SD, 13.4 years) were included, and most were of minority race/ethnicity (Black, 34.0%; Hispanic, 21.8%). The majority of participants met criteria for polypharmacy (58.4%) and multimorbidity (85.8%), with a mean prescription number of 6.5 (SD, ± 4.9) and mean number of medical comorbidities of 4.9 (SD, ± 3.3). Polypharmacy and multimorbidity were significantly associated with higher CRADI-8 scores. Specifically, polypharmacy was associated with straining with bowel movements and painful stools, whereas multimorbidity was associated with incomplete emptying and fecal urgency. There was no significant association between polypharmacy and multimorbidity with urinary symptoms, prolapse, or sexual dysfunction. CONCLUSIONS: Polypharmacy and multimorbidity are common in the urogynecologic population. There is a relationship between greater defecatory distress and polypharmacy and multimorbidity.

RESUMEN

OBJECTIVE: This meta-analysis aimed to compare the efficacy and safety of dexmedetomidine and clonidine as an adjuvant to local anesthetics in BPBs. METHODS: Two investigators independently searched databases to identify all RCTs comparing the efficacy and/or safety of dexmedetomidine and clonidine as an adjuvant to local anesthetics in BPBs. All outcomes were pooled using the inverse variance method with a random-effect model. An I2 test was used to assess heterogeneity. The source of heterogeneity was explored through meta-regression. The quality of the evidence was assessed using the GRADE approach. RESULTS: Out of 123 full texts assessed, 24 studies (1448 patients) were included in the analysis. As compared to clonidine, dexmedetomidine groups showed significantly longer sensory block duration (MD = 173.31; 95% CI 138.02‒208.59; I2 = 99%; GRADE approach evidence: high); motor block duration (MD = 158.35; 95% CI 131.55‒185.16; I2 = 98%; GRADE approach evidence: high), duration of analgesia (MD = 203.92; 95% CI 169.25‒238.58; I2 = 99%; GRADE approach evidence- high), and provided higher grade quality of block (RR = 1.97; 95% CI 1.60‒2.41; I2 = 0%; GRADE approach evidence: moderate). The block positioning technique (regression coefficient: 51.45, p = 0.005) was observed as a significant predictor of the heterogeneity in the case of sensory block duration. No significant difference was observed for the risk of hypotension (RR = 2.59; 95% CI 0.63‒10.66; I2 = %). CONCLUSION: Moderate to high-quality evidence suggests dexmedetomidine is a more efficacious adjuvant to local anesthetic in BPBs than clonidine.

RESUMEN

BACKGROUND: Robotic-Assisted Hysterectomies (RAH) require Trendelenburg positioning and pneumoperitoneum, which further accentuate alteration in respiratory mechanics induced by general anesthesia. The role of Recruitment Maneuver (RM) as a lung-protective strategy during intraoperative surgical settings has not been much studied. We planned this study to evaluate the effect of RM on perioperative oxygenation and postoperative spirometry using PaO2/FiO2 and FEV1/FVC, respectively in patients undergoing RAH. METHODS: Sixty-six ASA I‒II female patients scheduled for elective RAH were randomized into group R (recruitment maneuver, n = 33) or group C (control, n = 33). Portable spirometry was done one day before surgery. Patients were induced with general anesthesia, and mechanical ventilation started with volume control mode, with Tidal Volume (TV) of 6-8 mL.kg-1, Respiratory Rate (RR) of 12 min, inspiratory-expiratory ratio (I: E ratio) of 1:2, FiO2 of 0.4, and Positive End-Expiratory Pressure (PEEP) of 5 cmH2O. Patients in group R received recruitment maneuvers of 30 cmH2O every 30 minutes following tracheal intubation. The primary objectives were comparison of oxygenation and ventilation between two groups intraoperatively and portable spirometry postoperatively. Postoperative pulmonary complications, like desaturation, pulmonary edema, pneumonia, were monitored. RESULTS: Patients who received RM had significantly higher PaO2 (mmHg) (203.2+-24.3 vs. 167.8+-27.3, p < 0.001) at T2 (30 min after the pneumoperitoneum). However, there was no significant difference in portable spirometry between the groups in the postoperative period (FVC, 1.40 ± 0.5 L vs. 1.32 ± 0.46 L, p = 0.55). CONCLUSION: This study concluded that intraoperative recruitment did not prevent deterioration of postoperative spirometry values; however, it led to improved oxygenation intraoperatively.

RESUMEN

BACKGROUND: Nasogastric tube insertion and confirmation of its position can be difficult in the anesthetized patient. The purpose of the present study was to compare the bubble technique with the conventional method for confirmation of nasogastric tube placement in these patients. METHODS: Two hundred sixty adult patients, aged between 20...70 years, posted for surgeries requiring general anesthesia, tracheal intubation, and a nasogastric tube were enrolled in this study. Patients were randomized into 2 groups: Group B (Bubble group) and Group C (Control group). In Group C, a conventional technique using a lubricated nasogastric tube was positioned through the nostril with head remained neutral. In Group B, 2% lidocaine jelly was added to the proximal end to form a single bubble. The correct placement of the nasogastric tube in the stomach was confirmed by fluoroscopy by an independent observer intraoperatively. RESULTS: The duration of nasogastric tube insertion was 57.2..13.3seconds in Group B and 59.8..11.9seconds in Group C (p=0.111). The confirmation rate of the bubble technique was 76.8% (95% CI: 68.7...83.3), which was significantly better than the conventional method where the confirmation rate was 59.7% (95% CI 50.9...67.9), p<0.001. When compared to fluoroscopy, bubble technique was found to have a sensitivity of 92.3% (95% CI: 85.6...96.1) with specificity of 81.0% (95% CI: 60.0...92.3), positive predictive value of 96.0% (95% CI: 90.2...98.4), and a moderate negative predictive value of 68.0% (95% CI: 48.4...82.8). CONCLUSIONS: The bubble technique of nasogastric tube insertion has a higher confirmation rate in comparison to the conventional technique. TRIAL REGISTRY NUMBER: Clinical Trial Registry of India (CTRI/2018/09/015864).
