Complicações da comunicação buco-sinusal em cirurgias bucais: fatores de riscos, complicações e intervenções / Complications of oral-sinusal communication in oral surgery: risk factors and interventions

A comunicação buco-sinusal, uma conexão direta entre boca e seios maxilares, ocorre comumente pela extração de dentes próximos ao seio maxilar e outros procedimentos. O diagnóstico precoce é crucial para prevenir complicações graves. A abordagem terapêutica varia conforme o tamanho do defeito, presença de infecção e localização específica. Realizou-se uma breve revisão de literatura qualitativa abordando as principais complicações da comunicação buco sinusal na cirurgia bucal e como intervi-las. Buscou-se artigos científicos indexados nas seguintes bases de dados: Google Scholar, Pubmed e Biblioteca Scielo com lapso temporal de 2013 a 2023. Foram utilizados para esta busca os seguintes descritores: Comunicação buco-sinusal; Complicações; Seio maxilar. Os critérios de inclusão desta pesquisa foram artigos em inglês, português e espanhol, sendo selecionados 26 trabalhos. Os principais critérios de exclusão foram artigos com mais de 10 anos de publicação. A prevenção e gestão eficaz das complicações na comunicação oral em cirurgias são essenciais. Identificar fatores de risco, usar técnicas cirúrgicas precisas e agir imediatamente diante de sinais de comunicação com os seios da face são medidas cruciais para garantir a segurança do paciente e aprimorar os resultados cirúrgicos.

Oral-sinusal communication, a direct connection between the mouth and maxillary sinuses, commonly occurs due to the extraction of teeth close to the maxillary sinus and other procedures. Early diagnosis is crucial to prevent serious complications. The therapeutic approach varies according to the size of the defect, presence of infection and specific location. A brief qualitative literature review was carried out looking at the main complications of oral sinus communication in oral surgery and how to intervene. We searched for scientific articles indexed in the following databases: Google Scholar, Pubmed and Scielo Library with a time span from 2013 to 2023. The following descriptors were used for this search: Oral-sinus communication; Complications; Maxillary sinus. The inclusion criteria for this study were articles in English, Portuguese and Spanish, and 26 papers were selected. The main exclusion criteria were articles published more than 10 years ago. The prevention and effective management of oral communication complications during surgery are essential. Identifying risk factors, using precise surgical techniques and acting immediately in the event of signs of communication with the sinuses are crucial measures to ensure patient safety and improve surgical outcomes.

Prevalence and Correlates of Intimate Partner Violence Among Women and Men in Mexico: A Systematic Review and Meta-analysis.

This article presents the first systematic review and meta-analysis of the prevalence and correlates of different forms of intimate partner violence (IPV) among women and men in Mexico. To identify studies, a comprehensive search strategy was developed and executed across 11 databases (Academic Search Complete, APA PsycInfo, CINAHL, Cochrane CENTRAL, Embase, International Bibliography of the Social Sciences, LILACS, MEDLINE, SciELO, Sociological Abstracts, Web of Science). From the 1,746 studies screened, 155 full-text articles were reviewed, and this systematic review included 27 studies involving 249,557 participants to determine the prevalence of physical, psychological, sexual, threats, and other forms of IPV, according to gender and other sociodemographic characteristics. Overall IPV prevalence was 16.4%, with significant differences across pregnant and non-pregnant women. Physical IPV prevalence was 14.7%, revealing higher rates in men (29.5%) compared to women (14.2%). Psychological IPV prevalence was 27.3% and sexual IPV was at 6.6%, with differences across evaluation periods. Threats and other IPV forms showed a prevalence rate of 14.2% and 21.5%. Meta-regression analyses included gender, education, marital status, rural residency, pregnancy, age, and evaluation period. This study demonstrates that IPV is a critical public health concern in Mexico, impacting both women and men. It shows the vulnerability of rural residents, youth, and pregnant women. However, understanding IPV complexities in Mexico requires nuanced considerations of demographic and situational contexts. Urgent initiatives from municipal, state, and federal governments are needed to combat IPV, focusing on prevention and support for affected individuals.

Predictors of ischemic stroke in Chagas disease: Insights into mechanisms beyond cardiomyopathy severity.

BACKGROUND: Chagas disease is a risk factor for ischemic stroke, which causes high mortality rates and significant disability. This study aims to determine the incidence and risk factors for ischemic strokes in a large cohort of Chagas cardiomyopathy patients, with a particular focus on the mechanisms involved in the pathophysiology of stroke in this condition. METHODS: The study enrolled 517 patients with Chagas cardiomyopathy who were referred to our institution from March 2000 to December 2021. All patients underwent systematic cardiological and neurological assessments. The primary outcome was the occurrence of ischemic stroke during the follow-up period, classified based on the SSS-TOAST and CCS criteria. Natural cubic splines functions were applied to examine the potential nonlinear association between continuous variables and stroke risk. RESULTS: The mean age of the cohort was 52 ± 13 years, and 299 (58 %) were men. During a mean follow-up period of 4.8 years (interquartile range-IQR 1.1 to 7.1 years), a total of 72 patients (14.8 %) had an ischemic stroke, being fatal in 10. The overall incidence rate of ischemic stroke was 3.0/100 patient-years (95 % confidence interval 2.4 to 3.8). The stroke subtypes were cardioembolic (n = 41), undetermined (n = 11), and other subtypes (n = 20). The predictors of stroke were age, left atrial volume, left ventricular ejection fraction (LVEF), LV thrombus and prior stroke with thrombus. There was a nonlinear relationship between stroke risk, LVEF, and left atrial volume. A bimodal distribution of stroke occurrences was observed according to the severity of LV dysfunction, with a threshold for LVEF of 45 %. The final model for stroke risk prediction showed good discrimination, with a C statistic of 0.775. CONCLUSIONS: In a contemporary cohort of Chagas disease patients with a broad spectrum of disease severity, stroke incidence remains high despite anticoagulation. Stroke risk shows a nonlinear association with ventricular dysfunction and left atrial size, highlighting a distinct bimodal pattern of stroke occurrence in Chagas disease.

Eighteen-year trends in the rates of intra-operative cardiac arrest and associated mortality at a public university hospital in Brazil.

BACKGROUND: Intra-operative cardiac arrest is a rare but life-threatening event. Over the past two decades, various initiatives have improved the care of patients undergoing surgery at our quaternary teaching hospital in Brazil. We aimed to evaluate the epidemiology of intra-operative cardiac arrest and associated 30-day mortality over an 18-year period. A secondary aim was to identify associated risk factors. METHODS: We conducted a retrospective observational study using data collected from 1 January 2005 to 31 December 2022. Factors associated with cardiac arrest and mortality were identified using multivariable logistic regression analysis. RESULTS: Among the 154,178 cases, the overall rates of intra-operative cardiac arrest (n = 297) and associated 30-day mortality (n = 248) were 19.3 (95%CI (16.6-21.9)) and 16.1 (95% CI 13.9-18.3) per 10,000 anaesthetics, respectively. These decreased over time (2005-2010 vs. 2017-2022) from 26.3 (95%CI 21.0-31.6) to 15.4 (95%CI 12.0-18.7) per 10,000 anaesthetics, and from 23.4 (95%CI 18.8-28.1) to 13.7 (95%CI 10.8-16.7) per 10,000 anaesthetics, respectively. Factors associated with intra-operative cardiac arrest included children aged < 1 year (adjusted OR (95%CI) 3.51 (1.87-6.57)); ASA physical status 3-5 (adjusted OR (95%CI) 13.85 (8.86-21.65)); emergency surgery (adjusted OR (95%CI) 10.06 (7.85-12.89)); general anaesthesia (adjusted OR (95%CI) 8.79 (4.60-19.64)); surgical procedure involving multiple specialities (adjusted OR (95%CI) 9.13 (4.24-19.64)); cardiac surgery (adjusted OR (95%CI) 7.69 (5.05-11.71)); vascular surgery (adjusted OR (95%CI) 6.21 (4.05-9.51)); and gastrointestinal surgery (adjusted OR (95%CI) 2.98 (1.91-4.65)). DISCUSSION: We have shown an important reduction in intra-operative cardiac arrest and associated 30-day mortality over an 18-year period. Identification of relative risk factors associated with intra-operative cardiac arrest can be used to improve the safety and quality of patient care, especially in a resource-limited setting.

The burden of pre-operative anaemia and postoperative outcomes in 15 166 surgical patients from a public hospital in Brazil: A retrospective cohort study.

BACKGROUND: Preoperative anaemia is associated with poor postoperative outcomes; however, few studies have reported its prevalence in developing countries and its association with significant postoperative outcomes. OBJECTIVE: We aimed to identify the prevalence of anaemia and its association with postoperative outcomes in a major public hospital in Brazil. DESIGN: Retrospective cohort study. SETTING: Single-centre, 860-bed, quaternary university-affiliated teaching hospital in Southern Brazil. PATIENTS: We included adult patients who had undergone surgery between 2015 and 2019. Main outcome measures: The main outcome was the in-hospital 30-day postoperative mortality. According to the World Health Organisation, we defined anaemia and its sub-classification (mild, moderate, and severe). We developed Poisson regression models to examine the association between preoperative anaemia and outcomes. RESULTS: We included 15 166 patients, of whom 6387 (42.1%) were anaemic. After adjustment for confounding factors, patients with anaemia had an increased risk of in-hospital 30-day postoperative mortality (relative risk (RR) 1.69, 95% confidence interval (CI) 1.44 to 1.99, P  < 0.001). Mild [relative risk (RR) 1.38, 95% CI 1.12 to 1.71, P  = 0.003], moderate (RR 1.73, 95% CI 1.43 to 2.10, P  < 0.001), and severe anaemia (RR 2.43, 95% CI 1.92 to 3.07, P  < 0.001) were associated with the primary outcome. Anaemia increased the transfusion risk (RR 4.44, 95% CI 3.90 to 5.06, P  < 0.001) and postoperative intensive care unit (ICU) admission (RR 1.09, 95% CI 1.04 to 1.16, P  = 0.001). CONCLUSIONS: Four out of 10 patients had anaemia. These patients had an increased risk of adverse postoperative outcomes. Comprehension of the magnitude and impact of anaemia is essential to establish interventions in low-resource scenarios to optimise the patient's journey.

Epidemiological characterization of clubfoot: a population-based study of a surveillance program in Colombia.

Clubfoot is a common musculoskeletal congenital abnormality, with a prevalence of 5-20 cases per 10 000 live births in low to middle-income countries. If left untreated, clubfoot causes severe consequences for the child: gait disturbances, reduced quality of life, and limited work opportunities. Our objective was to characterize clubfoot and determine its prevalence and associated risk factors in Bogotá and Cali, Colombia, from 2002 to 2020. A retrospective case-control study design was employed, analyzing data from birth defect reports provided by the Program for the Prevention and Follow-up of Congenital Defects and Orphan Diseases surveillance system. Cases included live births or stillbirths with clubfoot, while controls consisted of infants without congenital abnormalities, matched in terms of birth date and hospital. Prevalence was calculated considering a 95% confidence interval using Poisson distribution, and risk factors were assessed through adjusted odds ratios obtained by logistic regression model. Of 558 255 births, 861 cases of clubfoot were identified, 48.20% were postural clubfoot, and 15 cases were syndromic clubfoot. In Bogota, prevalence rate was 15.1 per 10 000 live births, whereas in Cali it was 17.29 per 10 000 live births. Family history of clubfoot within first-degree relatives was identified as a risk factor for clubfoot. Investigating risk factors for clubfoot holds significant importance in terms of preventing and reducing morbidity within this population. Helping to drive government and healthcare initiatives aimed at providing timely and effective treatment.

Introduction: The advancement of the COVID-19 pandemic has resulted in changes in the sleep patterns of the population. Sleep disorders are related to major mental health changes and are also associated with psychosocial factors. Objective: To estimate the prevalence and factors associated with sleep quality changes among users attended in Primary Health Care during the COVID-19 pandemic. Methods: This was a cross-sectional study involving adults (age >18 years) of both genders who were being followed at a healthcare unit. Information was gathered from the unit's electronic medical records, and during home visits (between August and September 2021), socioeconomic data, risk factors, vital signs, anthropometric variables, lifestyle habits, current medications, healthcare service utilization, hospitalization, and consultations in the past year were collected. Quality of life was assessed using the SF-36 questionnaire, and the Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Results: The sample consisted predominantly of women (82.9%) with an average age of 60.5±11.7 years, of white ethnicity (70.7%), with a partner (61%), and belonging to class C (65.8%). 53.7% of the sample had up to two comorbidities, 87.8% were overweight/obese, and 80% were using antihypertensive medication. The prevalence of poor sleep quality was 87.8% (95%CI 73.1­95.0). The findings indicate a relationship between poor sleep quality and alcohol consumption, the presence of ≥3 comorbidities, systolic blood pressure levels, use of anxiolytics, education level, and the use of healthcare services during the pandemic. Conclusions: The high prevalence of poor sleep quality in the study sample suggests that sociodemographic determinants, presence of comorbidities, and lifestyle habits should be considered to minimize the effects of sleep disturbances during the pandemic.

Prevention and Control of Noncommunicable Diseases and Mental Health Conditions in Peru: The Case for Investment

Noncommunicable diseases (NCDs) and mental disorders are the leading causes of morbidity and mortality in Peru. NCDs account for seven out of every 10 deaths in the country, and nearly half of all people who die from NCDs in Peru are under the age of 70. In addition to the burden they impose on health, these diseases represent a significant burden on the national economy: treating them is expensive and those who suffer from them are more likely to stop working, be absent from work, or work with reduced capacity. Moreover, this situation generates high social costs, since mental health is fundamental to personal well-being, relationships, and making a positive contribution to society. This investment case was conducted in collaboration with the Ministry of Health of Peru, the World Health Organization/Pan American Health Organization, and UNDP. It is intended to strengthen the country's capacity to generate economic evidence on NCDs and mental disorders and to develop, finance, and implement national prevention and control strategies across sectors. The calculated return on investment for the next 15 years is based on three groups of interventions: 1) policies to control tobacco, alcohol, and salt consumption; 2) measures to control cardiovascular disease and diabetes; and 3) expanded treatment of mental disorders, particularly depression, anxiety, and psychotic conditions. Although NCDs and mental disorders represent a considerable burden on health and the economy, this investment case shows that Peru can greatly reduce the burden if it implements the measures recommended by WHO to tackle these diseases more effectively.

Acute infections of the central nervous system in children and adults: diagnosis and management.

Central nervous system infections are due to different microorganisms such as viruses, bacteria, mycobacteria, fungi, amoebas, and other parasites. The etiology depends on multiple risk factors, and it defines the infection location because some microorganisms prefer meninges, brain tissue, cerebellum, brain stem or spinal cord. The microorganisms induce diseases in the nervous system through direct invasion, neurotoxin production, and the triggered immune response. To determine the infection etiology, there are several diagnostic tests which may be conducted with cerebrospinal fluid, blood, respiratory and stool samples. These tests include but are not limited to direct microscopic examination of the sample, stains, cultures, antigenic tests, nucleic acid amplification tests, metagenomic next-generation sequencing, immunologic biomarker and neuroimaging, especially contrast-enhanced magnetic resonance imaging. The treatment may consist of specific antimicrobial treatment and supportive standard care. Since viruses have no specific antiviral treatment, antimicrobial treatment is mainly targeted at non-viral infections. This article will focus on diagnosis and treatment of acute acquired infections of the central nervous system beyond the neonatal period. The discussion defines the disease, provides the clinical presentation, explains the etiology and risk factors, and briefly mentions potential complications. This updated review aims to provide the reader with all the elements needed to adequately approach a patient with a central nervous system infection. Mycobacterium tuberculosis infection, Cryptococcus spp. infection and vaccines are not within the scope of this article.

Performance of SARC-F and SARC-CalF scores to predict risk of mortality in hemodialysis patients: a cohort study.

This study aimed to evaluate the association between the questionnaires SARC-F and SARC-CalF with risk of mortality in patients undergoing hemodialysis (HD). A cohort study, with patients on HD age ≥ 18 years, both sex, between June 2019 and April 2023. Body composition (anthropometry and bioelectrical impedance), muscle functional (handgrip strength and gait speed), screening of sarcopenia using the SARC-F and SARC-CalF, nutritional status and laboratory data were assessed. Follow-up for mortality up to 47 months. The sample consisted of 243 participants and the prevalence of risk of sarcopenia using SARC-F and SARC-CalF were 30% and 45%, respectively; 65 died for all reasons and three patients were censored due to transplantation. Multivariate analysis identified SARC-CalF as predictor of mortality in HD patients [hazard ratio 1.96; 95% CI (1.01-3.79); p = 0.04]. The survival analysis showed that there was a significant difference in the survival curves among the groups stratified by SARC-F and SARC-CalF for log-rank test. A higher specificity was found for SARC-CalF than SARC-F (80% vs. 77%) in receiver operating characteristic (ROC) curve. Both questionnaires were associated with anthropometric, parameters of body composition, physical measurements, and SARC-CalF was predictor of risk for mortality in HD patients.

Perceptions and attitudes about the contribution of the environment to childhood cancer: a pilot study in a medical guild and undergraduate students.

BACKGROUND: Identifying and recognizing environmental risk factors for childhood cancer is crucial to prevent it. Medical guild are the first contact to monitor children's health. Therefore, courses about the contribution of chemical toxins in the environment and health outcomes such as cancer should be included in their professional training. This study aimed to evaluate the perceptions and attitudes of a medical guild and undergraduate students in health sciences about the contribution of the environment to childhood cancer. METHODS: A pilot study was conducted, an online survey including thirteen questions was shared among medical guild members and undergraduate students in health sciences. Frequencies, percentages, and chi-square homogeneity tests were calculated to compare groups. RESULTS: Genetic factors ranked as the first possible cause of childhood cancer (88.2% medical guild and 97.7% undergraduate students). However, 70.6% of medical guild and 64.6% of undergraduate students reported that they have ever suspected that childhood cancer could be related to the environmental conditions in which children live. More than 95% of the participants reported that they would find it useful to have more knowledge about environmental risks and cancer. When data were analyzed by profession (medical guild) and academic year (undergraduate students), no significant differences were observed. Nonetheless, comparisons by academic discipline between undergraduate students, showed that a higher percentage of medicine and environmental sciences and health (over 98%) reported environmental exposure as risk factors associated with childhood cancer compared to 75% from physiotherapy, (p = 0.001). CONCLUSIONS: In this study, the environmental contribution to childhood cancer is not clear among the medical guild and undergraduate students. They should be trained on the topic of cancer and the environment.

Depression symptoms are associated with demographic characteristics, nutritional status, and social support among young adults in Chile: a latent class analysis.

BACKGROUND: Depressive disorders are a critical public health concern in Chile. Nonetheless, there is a lack of evidence regarding the identification of depressive symptom clusters. The objective was to identify depressive symptom clusters among Chilean young adults and examine how demographic, and lifestyle factors as well as social support can influence and predict them. METHODS: Cross-sectional study conducted among 1,000 participants from the Limache cohort 2. A latent class analysis (LCA) was performed to identify depressive symptom clusters, using the Patient Health Questionnaire (PHQ-9). Multinomial logistic regression was then applied to explore the associations between identified classes and potential predictors. The models were adjusted by age and sex. RESULTS: Three latent classes of depressive symptoms were identified: minimal (25.7%); somatic (50.7%) and severe (23.6%). In the severe class for eight out nine depressive symptoms the probabilities were above 50%, and the probability of suicidal ideation was almost a third in this class. Being female (Adjusted Odds ratio [AOR], 2.49; 95% confidence interval [CI] [1.63-3.81]), current smoker (AOR, 1.74; 95% CI [1.15-2.65]), having basic education (AOR, 3.12; 95% CI [1.30-7.53]) and obesity (AOR, 2.72; 95% CI [1.61-4.59]) significantly increased the likelihood of belonging to severe class. Higher social support decreased the odds of being in the somatic (OR, 0.96; 95% CI [0.93-0.98]) and severe (OR, 0.92; 95% CI [0.90-0.94]) classes. CONCLUSIONS: These findings highlight the importance of individualized intervention strategies for depression management. Also, the study suggests that nutritional status and social support should be considered when addressing depression in this population.

Acute kidney injury and mortality in patients with critical COVID-19 in Mexico: case-control study.

OBJECTIVE: We aimed to test the association between acute kidney injury (AKI) and mortality in critically ill patients with Coronavirus disease 2019 (COVID-19). METHOD: We conducted a single-center case-control study at the intensive care unit (ICU) of a second-level hospital in Mexico. We included 100 patients with critical COVID-19 from January to December 2021, and collected demographic characteristics, comorbidities, APACHE II, SOFA, NEWS2, and CO-RADS scores at admission, incidence of intrahospital complications, length of hospital and ICU stay, and duration of mechanical ventilation, among others. RESULTS: The median survival of deceased patients was 20 days. After multivariable logistic regression, the following variables were significantly associated to mortality: AKI (adjusted odds ratio [AOR] 6.64, 95% confidence intervals [CI] = 2.1-20.6, p = 0.001), age > 55 years (AOR 5.3, 95% CI = 1.5-18.1, p = 0.007), and arrhythmias (AOR 5.15, 95% CI = 1.3-19.2, p = 0.015). Median survival was shorter in patients with AKI (15 vs. 22 days, p = 0.043), as well as in patients with overweight/obesity (15 vs. 25 days, p = 0.026). CONCLUSION: Our findings show that the development of AKI was the main risk factor associated with mortality in critical COVID-19 patients, while other factors such as older age and cardiac arrhythmias were also associated with this outcome. The management of patients with COVID-19 should include renal function screening and staging on admission to the Emergency Department.

OBJETIVO: Probar la asociación entre lesión renal aguda y mortalidad en pacientes con COVID-19 grave. MÉTODO: Realizamos un estudio de casos y controles unicéntrico en la unidad de cuidados intensivos (UCI) de un hospital de segundo nivel en México. Incluimos 100 pacientes con COVID-19 grave de enero a diciembre 2021, recolectando características demográficas, comorbilidad, APACHE II, SOFA, NEWS2 y CO-RADS al ingreso, incidencia de complicaciones intrahospitalarias, duración de la estancia hospitalaria y en la UCI, duración de ventilación mecánica, etc. RESULTADOS: La mediana de supervivencia de los pacientes que fallecieron fue de 20 días. Al realizar el análisis de regresión logística multivariable, las siguientes variables se asociaron significativamente con la mortalidad: lesión renal aguda (odds ratio ajustada [ORa]: 6.64; intervalo de confianza del 95% [IC95%]: 2.1-20.6; p = 0.001), edad > 55 años (ORa: 5.3; IC95%: 1.5-18.1; p = 0.007) y arritmias (ORa: 5.15; IC95%: 1.3-19.2; p = 0.015). La supervivencia fue menor en pacientes con lesión renal aguda (15 vs. 22 días; p = 0,043), así como en pacientes con sobrepeso u obesidad (15 vs. 25 días; p = 0.026). CONCLUSIONES: Nuestros resultados muestran que el desarrollo de lesión renal aguda es el principal factor de riesgo asociado a mortalidad en pacientes con COVID-19 grave, mientras que otros factores, como la edad > 55 años y la presencia de arritmias cardiacas, también se asocian a mortalidad por COVID-19. El manejo de pacientes con COVID-19 debe incluir el tamizaje y la estadificación de la función renal al ingreso a urgencias.

Tabular review of contemporary fenestrated-branched endovascular aortic repair experiences for treatment of thoracoabdominal aortic aneurysms.

INTRODUCTION: Repair of thoracoabdominal aortic aneurysms (TAAAs) represents a technical challenge regardless of which technique is used. Open surgical repair (OSR) is the time-tested option against which novel techniques must be compared and it is still considered the gold standard option for younger, fit patients with heritable aortic diseases. Endovascular repair offers a less-invasive alternative in patients with suitable anatomy. This article aims to present a tabular review of the contemporary published data on endovascular repair of TAAAs using fenestrated-branched techniques. EVIDENCE ACQUISITION: The published literature for single-center and multicenter studies evaluating the outcomes of FB-EVAR for TAAAs was searched using MEDLINE and Embase databases. Studies published between January 1st 2010 and July 11th 2024, in the English language which provided data on FB-EVAR of TAAAs with more than fifty reported cases were included. EVIDENCE SYNTHESIS: The average patient age at time of repair was 71 years old with majority of males (65.5%). Most patients presented with a Crawford Extent II TAAAs (21.6%), followed by Extent III (21.2%). Early mortality was 4.9% for the entire cohort. The most prevalent adverse event was acute kidney injury (9.4%), followed by spinal cord injury (8.0%). CONCLUSIONS: FB-EVAR of TAAAs continues to evolve. Pooled analysis of early mortality and morbidity is lower in this tabular review than historical outcomes of open TAAA repair.

Prevalence of syphilis and associated factors among pregnant women in Brazil: systematic review and meta-analysis.

Objective: This systematic review accompanied by a meta-analysis aimed to estimate the prevalence of syphilis in pregnant women in Brazil and describe its associated factors. Methods: Following the establishment the search strategies and the registration of the review protocol in PROSPERO, we conducted a search for relevant articles in the Pubmed, LILACS, Science Direct, SciELO and Web of Science databases. Our inclusion criteria were cross-sectional studies published between 2005 and 2023, with no language restrictions. The combined prevalence of syphilis infection was estimated using the random effects model in the R Software with a 95% confidence interval (95% CI) and p < 0.01 as statistically significant. Results: A total of 24 articles were recruited, which together investigated 221,884 women. The combined prevalence of syphilis in pregnant women in Brazil was 1.79% (95% CI: 1.24-2.57%), and the main factors associated with its occurrence were black and brown skin color, low education and factors related to the partner. Conclusion: There was a high prevalence of syphilis in pregnancy in Brazil, mainly associated with socioeconomic factors.

Risk factors associated with the occurrence of the adverse event phlebitis in hospitalized adult patients.

OBJECTIVES: to synthesize knowledge regarding risk factors associated with occurrence of adverse event phlebitis in hospitalized adult patients. METHODS: an integrative literature review, carried out in the CINAHL, PubMed, Virtual Health Library, Embase, Web of Science and Scopus databases. The stages were carried out independently by two reviewers, and the data were analyzed descriptively. RESULTS: from the analysis of 31 quantitative primary studies, the following risk factors were summarized: length of stay; use of antibiotics; peripheral intravenous catheter dwell time; receive less nursing care; catheter inserted multiple times; patients with infection and comorbidities; presence of pain at catheter insertion site; Teflon® catheter use; reduced patient mobility; quality of patient's vein; skin elasticity; unsuccessful insertion. CONCLUSIONS: it is necessary to standardize the format for measuring occurrence of this adverse event and develop new studies with a higher level of evidence.

Genetic and Anthropometric Interplay: How Waist-to-Hip Ratio Modulates LDL-c Levels in Mexican Population.

BACKGROUND/OBJECTIVES: Genetic factors contribute to the physiopathology of obesity and its comorbidities. This study aimed to investigate the association of the SNPs ABCA1 (rs9282541), ADIPOQ (rs2241766), FTO (rs9939609), GRB14 (rs10195252), and LEPR (rs1805134) with various clinical, anthropometric, and biochemical variables. METHODS: The study included 396 Mexican mestizo individuals with obesity and 142 individuals with normal weight. Biochemical markers were evaluated from peripheral blood samples, and SNP genotyping was performed using PCR with TaqMan probes. A genetic risk score (GRS) was computed using an additive model. RESULTS: No significant associations were found between the SNPs ABCA1, ADIPOQ, FTO, and LEPR with obesity. However, the T allele of the GRB14 SNP was significantly associated with obesity (χ2 = 5.93, p = 0.01; OR = 1.52; 95% CI: 1.08-2.12). A multivariate linear regression model (adjusted R-squared: 0.1253; p < 0.001) predicting LDL-c levels among all participants (n = 538) identified significant (p < 0.05) beta coefficients for several anthropometric and biochemical variables, as well as for the GRS. Additionally, the interaction between the GRS and the waist-to-hip ratio (WHR) showed a negative beta coefficient (BC = -26.5307; p = 0.014). Participants with a WHR < 0.839 showed no effect of GRS on LDL-c concentration, while those with a WHR > 0.839 exhibited a greater effect of GRS (~9) at lower LDL-c concentrations (~50 mg/dL) and a lesser effect of GRS (~7) at higher LDL-c concentrations (~250 mg/dL). CONCLUSIONS: A significant interaction between genetics and WHR influences LDL-c in Mexicans, which may contribute to the prevention and clinical management of dyslipidemia and cardiovascular disease.

Continued Breastfeeding in a Birth Cohort in the Western Amazon of Brazil: Risk of Interruption and Associated Factors.

BACKGROUND: Continued breastfeeding reduces infant mortality and provides nutritional, immunological, and developmental benefits for the child. OBJECTIVES: A prospective cohort study conducted in 2015 followed 608 children who were breastfed between 6 and 24 months. The study assessed the risk of breastfeeding interruption at 12, 18, and 24 months, as well as the factors associated with this outcome, in a cohort of newborns in Rio Branco, using the life table method. METHODS: The factors associated with breastfeeding cessation and their 95% confidence intervals (CI95%) were analyzed using both crude and adjusted Cox proportional hazards regression in a hierarchical model. The risks of breastfeeding cessation at 12, 18, and 24 months were 19%, 65%, and 71%, respectively. RESULTS: Factors positively associated with the risk of breastfeeding cessation include the use of a pacifier before 6 weeks of age (HR = 1.62; CI: 95% 1.24-2.11) and the use of a bottle during the first year of life (HR = 1.41; CI: 95% 1.11-1.78). Maternal return to work after the birth of the baby (HR = 0.78; CI: 95% 0.62-0.97) was found to be negatively associated with the risk of breastfeeding interruption. CONCLUSIONS: Early pacifier use before 6 weeks and the introduction of a bottle in the first year affect continued breastfeeding. Maternal employment was associated with reduced risk of breastfeeding cessation, contrary to most studies.

The gut microbiota as a link between Alzheimer's disease and obesity.

Alzheimer's disease (AD) is a degenerative disease that causes a progressive decline in memory and thinking skills. Over the past few years, diverse studies have shown that there is no single cause of AD; instead, it has been reported that factors such as genetics, lifestyle, and environment contribute to the pathogenesis of the disease. In this sense, it has been shown that obesity during middle age is one of the most prominent modifiable risk factors for AD. Of the multiple potential mechanisms linking obesity and AD, the gut microbiota (GM) has gained increasing attention in recent years. However, the underlying mechanisms that connect the GM with the process of neurodegeneration remain unclear. Through this narrative review, we present a comprehensive understanding of how alterations in the GM of people with obesity may result in systemic inflammation and affect pathways related to the pathogenesis of AD. We conclude with an analysis of the relationship between GM and insulin resistance, a risk factor for AD that is highly prevalent in people with obesity. Understanding the crosstalk between obesity, GM, and the pathogenesis of AD will help to design new strategies aimed at preventing neurodegeneration.
