Hipotermia terapéutica: estudio descriptivo de una cohorte de 10 años en un hospital público de alta complejidad / Therapeutic hypothermia: A descriptive, cohort study conducted over 10 years at a tertiary care public hospital

Introducción. La hipotermia terapéutica (HT) reduce el riesgo de muerte o discapacidad en niños con encefalopatía hipóxico-isquémica (EHI) moderada-grave. Objetivo. Describir una población de pacientes con EHI que requirió HT y su evolución hasta el alta hospitalaria. Población y métodos. Estudio descriptivo de cohorte retrospectivo. Se analizaron todos los pacientes que ingresaron a HT entre 2013 y 2022. Se evaluaron datos epidemiológicos, clínicos, de monitoreo, tratamiento, estudios complementarios y condición al alta. Se compararon los factores de riesgo entre pacientes fallecidos y sobrevivientes, y de estos, los que requirieron necesidades especiales al alta (NEAS). Resultados. Se incluyeron 247 pacientes. Mortalidad: 11 %. Evento centinela más frecuente: período expulsivo prolongado (39 %). Inicio del tratamiento: mediana 5 horas de vida. Convulsiones: 57 %. Eritropoyetina intravenosa: 66,7 %. Patrón anormal de monitoreo de función cerebral: 52 %. Normalización del monitoreo: mediana 24 horas. Resonancia magnética patológica: 42 %. Variables predictoras de mortalidad: Sarnat y Sarnat grave, y ecografía patológica al ingreso. Conclusión. La mortalidad global fue del 11 %. Las derivaciones aumentaron en forma más evidente a partir del año 2018. El horario de inicio de HT fue más tardío que en reportes anteriores. Los signos neurológicos de gravedad según la escala de Sarnat y Sarnat y la ecografía cerebral basal patológica fueron predictores independientes de mortalidad al alta. Los pacientes con NEAS presentaron normalización del trazado del electroencefalograma de amplitud integrada más tardío. El hallazgo más frecuente en la resonancia fue la afectación de los ganglios basales. No se encontraron diferencias clínicas ni de complicaciones estadísticamente significativas entre los pacientes que recibieron eritropoyetina.

Introduction. Therapeutic hypothermia (TH) reduces the risk of death or disability in children with moderate to severe hypoxic ischemic encephalopathy (HIE). Objective. To describe a population of patients with HIE that required TH and their course until discharge. Population and methods. Retrospective, descriptive, cohort study. All patients admitted to TH between 2013 and 2022 were studied. Epidemiological, clinical, monitoring, and treatment data were assessed, together with supplementary tests and condition at discharge. Risk factors were compared between deceased patients and survivors; and, among the latter, those requiring special healthcare needs (SHCN) at discharge. Results. A total of 247 patients were included. Mortality: 11%. Most common sentinel event: prolonged second stage of labor (39%). Treatment initiation: median of 5 hours of life. Seizures: 57%. Intravenous erythropoietin: 66.7%. Abnormal pattern in brain function monitoring: 52%. Normalization of monitoring: median of 24 hours. Pathological magnetic resonance imaging: 42%. Predictor variables of mortality: severe Sarnat and Sarnat staging and pathological ultrasound upon admission. Conclusion. The overall mortality rate was 11%. Referrals increased more markedly since 2018. The time of TH initiation was later than in previous reports. Severe neurological signs as per the Sarnat and Sarnat staging and a pathological baseline cranial ultrasound were independent predictors of mortality at discharge. Patients with SHCN at discharge showed a normalized tracing in the amplitude-integrated electroencephalography performed later. The most common finding in the magnetic resonance imaging was basal ganglia involvement. No statistically significant differences were observed in terms of clinical characteristics or complications among patients who received erythropoietin.

Iatrogenic urinary injuries in colorectal surgery: outcomes and risk factors from a nationwide cohort.

BACKGROUND: Iatrogenic urinary injury (IUI) can lead to significant complications after colorectal surgery, especially when diagnosis is delayed. This study analyzes risk factors associated with IUI and delayed IUI among patients undergoing colorectal procedures. METHODS: Adults undergoing colorectal surgery between 2012 and 2021 were identified in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP®) database. Multivariable regression analysis was used to determine risk factors and outcomes associated with IUI and delayed IUI. RESULTS: Among 566,036 patients, 5836 patients (1.0%) had IUI after colorectal surgery, of whom 236 (4.0%) had delayed IUI. Multiple preoperative risk factors for IUI and delayed IUI were identified, with disseminated cancer [adjusted odds ratio (aOR) 1.4, 95% confidence interval (CI) 1.2-1.5; p < 0.001] and diverticular disease [aOR 1.1, 95% CI 1.0-1.2; p = 0.009] correlated with IUI and increased body mass index [aOR 1.6, 95% CI 1.2-2.1; p = 0.003] and ascites [aOR 5.6, 95% CI 2.1-15.4; p = 0.001] associated with delayed IUI. Laparoscopic approach was associated with decreased risk of IUI [aOR 0.4, 95% CI 0.4-0.5; p < 0.001] and increased risk of delayed IUI [aOR 1.8, 95% CI 1.4-2.5; p < 0.001]. Both IUI and delayed IUI were associated with significant postoperative morbidity, with severe multiorgan complications seen in delayed IUI. CONCLUSIONS: While IUI occurs infrequently in colorectal surgery, unrecognized injuries can complicate repair and cause other negative postoperative outcomes. Patients with complex intra-abdominal pathology are at increased risk of IUI, and patients with large body habitus undergoing laparoscopic procedures are at increased risk of delayed IUI.

Preliminary investigation of MMP8 (rs11225395) and MMP9 (rs3787268) polymorphisms association with breast cancer risk in pashtun women of Pakistan.

BACKGROUND: Single Nucleotide polymorphisms (SNPs) in MMP8 and MMP9 have been widely associated with breast cancer risk in different ethnicities with inconsistent results. There is no such study conducted so far in the Pashtun population of Khyber Pakhtunkhwa, Pakistan. Therefore, this study was conducted to check MMP8 (rs11225395) and MMP9 (rs3787268) polymorphism with breast cancer risk in the selected population. METHODS: This study, consisting of 300 breast cancer patients and 168 gender and age-matched healthy controls was subjected to confirm MMP8 and MMP9 polymorphisms. Clinicopathological data and blood samples were taken from all the participants. DNA was extracted and SNPs were confirmed using the T-ARMS-PCR protocol. RESULTS: Based on our study results, significant associations were observed between the MMP8 rs11225395 risk allele (G) and increased breast cancer risk, with the G allele frequency higher in patients (65%) compared to controls (51%) (OR = 1.752, 95% CI = 1.423-3.662, p = 0.002). Genotypes GG (OR = 4.218, p = 0.005) and AG (OR = 7.286, p = 0.0001) of MMP8 rs11225395 were also significantly associated with elevated breast cancer risk. Similarly, MMP9 rs3787268 exhibited a higher frequency of the risk allele (A) in breast cancer cases (81%) compared to controls (41%), correlating strongly with increased risk (OR = 6.320, p = 0.0001). Genotypes AA (OR = 14.500, p = 0.0001) and AG (OR = 2.429, p = 0.077) of MMP9 rs3787268 containing the risk allele showed significant associations with heightened breast cancer risk. Subgroup analyses based on age, disease progression, tumor size, and grade revealed noteworthy associations for both MMP8 rs11225395 and MMP9 rs3787268. MMP8 rs11225395 genotypes displayed significant correlations with age (p = 0.066), disease progression (p = 0.0001), larger tumor size (p = 0.005), and higher tumor grade (p = 0.006). Similarly, MMP9 rs3787268 genotypes were significantly associated with age (p = 0.001), disease progression (p = 0.010), larger tumor size (p = 0.018), and higher tumor grade (p = 0.037). Logistic regression analyses further underscored these genetic variants' potential role as biomarkers in breast cancer, particularly in relation to specific hormone receptor statuses such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) positivity. CONCLUSION: The results revealed significant associations between the mutant alleles and genotypes of MMP8 (rs11225395) and MMP9 (rs3787268) with increased breast cancer risk in the Pashtun population of Khyber Pakhtunkhwa, Pakistan. However, more investigation will be required on large data sets to confirm the selected SNPs and other SNPs in the selected and other related genes with the risk of breast cancer.

Socioeconomic Status and Major Adverse Transplant Events in Pediatric Heart Transplant Recipients.

Importance: Low socioeconomic status (SES) has been associated with higher risk of rejection and graft loss in pediatric heart transplant (HT) recipients. The association of SES with other posttransplant morbidities is unknown. Objective: To assess whether low SES is associated with higher risk of a major adverse transplant event (MATE) among pediatric HT recipients. Design, Setting, and Participants: Retrospective single-center cohort study at a children's hospital in Boston with consecutive primary HT recipients from 2006 to 2019 and follow-up through 2022. Data were analyzed from June 2023 to March 2024. Exposure: Very low or low, moderate, and high or very high Childhood Opportunity Index (COI) for neighborhood (census tract) of patient residence. Main Outcomes and Measures: Primary outcome was 3-year MATE-6 score assessed in 6-month survivors as cumulative burden of acute cellular rejection, antibody-mediated rejection, coronary vasculopathy, lymphoproliferative disease, kidney dysfunction, and infection, each as an ordinal score from 0 to 4 (24 for death or retransplant). Secondary outcomes were freedom from rejection during first 6 months, freedom from death or retransplant, MATE-3 score for events 1 to 3 (under immune suppression) and events 4 to 6 (chronic immune suppression effects), and each MATE component. Results: Of 153 children analyzed, the median (IQR) age at HT was 7.2 (1.5-14.8) years, 99 (65%) were male, 16 (10%) were Black, 17 (11%) were Hispanic, and 106 (69%) were White. Fifty patients (33%) lived in very low or low, 17 (11%) in moderate, and 86 (56%) in high or very high COI neighborhoods. There was no significant group difference in mean (SD) 3-year MATE-6 score (very low or low COI, 3.4 [6.5]; moderate COI, 2.4 [6.3]; and high or very high COI, 4.0 [6.9]). Furthermore, there was no group difference in mean (SD) MATE-3 scores for underimmune suppression (very low or low COI, 1.9 [3.5]; moderate COI, 1.2 [3.2]; and high or very high COI, 2.2 [3.6]), chronic immune suppression effects (very low or low COI, 1.6 [3.3]; moderate COI, 1.1 [3.2]; and high or very high COI, 1.8 [3.6]), individual MATE components, rejection during the first 6 months, or death or retransplant. Conclusions and relevance: In this cohort study of pediatric HT recipients, there was no difference in posttransplant outcomes among recipients stratified by SES, a notable improvement from prior studies. These findings may be explained by state-level health reform, standardized posttransplant care, and early awareness of outcome disparities.

Fear of Cancer Recurrence in Adult Survivors of Childhood Cancer.

Importance: Fear of cancer recurrence is common among survivors of adult-onset cancer and associated with increased distress, functional impairment, and health care utilization. However, little is known about the prevalence and risk factors of fear of cancer recurrence among adult survivors of childhood cancer who are also at high risk for subsequent malignant neoplasms. Objective: To characterize the prevalence of and risk factors for clinically significant fear of cancer recurrence in adult survivors of childhood cancer. Design, Setting, and Participants: This cross-sectional investigation included participants recruited from the Childhood Cancer Survivor Study, a retrospective cohort study of long-term childhood cancer survivors treated at 31 institutions between 1970 and 1999 across North America. Participants were recruited and completed psychosocial measures via online survey between October 2018 and April 2019. Cancer and treatment-related variables were abstracted from medical records. Data were analyzed from May 2023 to July 2024. Main Outcomes and Measures: Clinically significant fear of cancer recurrence was assessed via the Fear of Cancer Recurrence Inventory-Short Form. Poisson regression models estimated prevalence ratios (PRs) with 95% CIs adjusted for age and sex to examine the associations of demographic, disease, treatment, and psychosocial variables with fear of cancer recurrence. Results: The final sample included 229 adult survivors of childhood cancer (115 female [50.2%]; mean [SD] age, 39.6 [9.9] years; mean [SD] time since diagnosis, 31.7 [8.4] years). Among survivors, 38 (16.6%; 95% CI, 11.6%-21.6%) reported clinically significant fear of cancer recurrence, and an additional 36 (15.7%) reported high fear of cancer recurrence. Clinically significant fear of cancer recurrence was associated with unemployment (PR, 2.5; 95% CI, 1.3-4.8), presence of neurologic chronic health conditions (PR, 3.3; 95% CI, 1.8-6.1), treatment with pelvic radiation (PR, 2.9; 95% CI, 1.5-5.6), and amputation or limb sparing surgery (PR, 2.4; 95% CI, 1.2-4.9). Higher risk of clinically significant fear of cancer recurrence was also associated with having either elevated anxiety or depression (PR, 2.6; 95% CI, 1.2-5.9), having both elevated (PR, 3.2; 95% CI, 1.2-8.4), and perceived poor health status (PR, 3.0; 95% CI, 3.1-9.7). Conclusions and Relevance: Decades following treatment, one-third of childhood cancer survivors in this study reported elevated fear their cancer will recur or a subsequent malignant neoplasm will develop. Findings suggest that fear of cancer recurrence should be routinely screened, and clinically significant symptoms intervened upon as a part of survivorship care.

Epidemiological characteristics and prevention of pressure injury in older inpatients of Zhuang and Han ethnicity in Guangxi, China: a cross-sectional study.

BACKGROUND: Pressure injury (PI) is a significant health concern among older inpatients, particularly in regions with diverse ethnic populations. Understanding the epidemiological characteristics and preventive measures is crucial for improving patient outcomes. PURPOSE: To analyze the epidemiological characteristics, prevention status, and influencing factors of pressure injury (PI) in older inpatients of Zhuang and Han nationality in Guangxi, China. METHODS: A total of 2206 inpatients age 60 years or older in 2 class III grade A general hospitals in the Guangxi Zhuang Autonomous Region between April 1, 2021, and May 27, 2021, were included in this cross-sectional study. Epidemiological characteristics-including age, sex, educational background, race, ethnicity, and hospitalization information-were collected using a general information questionnaire designed by the researchers. The PI risk factors were evaluated using the Braden Scale. Prevention status was assessed using the Epidemiology and Prevention Skin Injuries in the Elderly Scale and Skin Injury Survey Scale. RESULTS: Of the total 2206 patients included in the study, 555 (25.16%) were of Zhuang nationality and 1651 (74.84%) were of Han nationality. The overall PI incidence was 2.58%, with PI prevalence of 1.80% and 2.85% in Zhuang and Han patients, respectively. The main influencing factor for PI in Zhuang patients was caregivers (P < .05), whereas in Han patients the main influencing factors were urinary conditions, Alzheimer disease, sedatives, and antihypertensive drugs (P < .05). CONCLUSION: The PI prevalence rates were similar in both ethnic groups. Health care staff in high-risk departments for PI must remain vigilant and take appropriate action.

Early postoperative complications of elective versus emergency stoma creation: a tertiary academic center experience.

BACKGROUND: Stoma creation is standard in general surgery, yet complication rates remain high. PURPOSE: This study investigated the incidence and risk factors for early postoperative stoma complications in elective vs emergency surgery. METHODS: All patients who underwent stoma creation between June 2015 and November 2020 were retrospectively reviewed and analyzed. Patients were divided into 2 groups based on the surgery type: elective vs emergency. RESULTS: A total of 375 patients were included in this study. Two hundred fifty-three patients (67.5%) underwent elective stoma creation, while 122 (32.5%) underwent stoma creation during an emergency surgery. In the emergency group, white blood cell, blood urea nitrogen, and creatinine levels were statistically significantly higher (P = .001, .001, and .002, respectively). Albumin levels were statistically significantly lower in the emergency group (P = .001). The mean Emergency Surgery Score was 5.17 ± 2.73 in the emergency group compared to 4.4 ± 2.44 in the elective group (P = .006). Colorectal cancer was the most common cause of stoma creation in both groups. In terms of stoma creation, colostomy was statistically significantly more common in the emergency group (59%, P = .001), compared to ileostomy in the elective group (58.9%, P = .001). Complications were observed in 135 of all patients (36%). Necrosis was statistically significantly more common in emergency cases (9.9%, P < .001). CONCLUSION: Surgeons should strive to optimize the patient's condition prior to the operation and, if possible, perform stoma marking or involve a stoma nurse in the operating room to select the most suitable site. In high-risk patients, where complications are more likely, the use of a stoma should be minimized and definitive management should always be pursued if feasible.

Influencing factors associated with peristomal skin complications after colorectal ostomy surgery: a systematic review and meta-analysis.

BACKGROUND: Peristomal skin complications (PSCs) are the most common complication among patients with ostomies after ostomy creation. PURPOSE: This systematic review and meta-analysis aimed to evaluate the factors influencing the occurrence of peristomal skin complications. METHODS: A systematic review was conducted across multiple databases by using a combination of subject terms and free words for online search. The databases were searched from their inception to October 31, 2023. All studies that met inclusion criteria were examined to identify risk factors for PSCs. Two researchers independently conducted literature screening and information extraction, evaluated the literature quality using the Newcastle-Ottawa Scale, and performed descriptive analysis of the results. RESULTS: Ten studies were included in this review. A total of 3753 patients with ostomies participated in the studies, and 981 patients suffered from PSCs, with PSC incidence ranging from 15.5% to 47.7%. Type of ostomy, diabetes, self-care knowledge, and chemotherapy were significant factors associated with PSCs. CONCLUSION: This review highlighted 4 factors that influence the occurrence of peristomal skin complications. The quality of included literature is generally low, with significant heterogeneity in study design and choice of outcome indicators. Therefore, further research involving high-quality studies with larger sample sizes is needed for deeper investigation.

Novel risk loci for COVID-19 hospitalization among admixed American populations.

The genetic basis of severe COVID-19 has been thoroughly studied, and many genetic risk factors shared between populations have been identified. However, reduced sample sizes from non-European groups have limited the discovery of population-specific common risk loci. In this second study nested in the SCOURGE consortium, we conducted a genome-wide association study (GWAS) for COVID-19 hospitalization in admixed Americans, comprising a total of 4702 hospitalized cases recruited by SCOURGE and seven other participating studies in the COVID-19 Host Genetic Initiative. We identified four genome-wide significant associations, two of which constitute novel loci and were first discovered in Latin American populations (BAZ2B and DDIAS). A trans-ethnic meta-analysis revealed another novel cross-population risk locus in CREBBP. Finally, we assessed the performance of a cross-ancestry polygenic risk score in the SCOURGE admixed American cohort. This study constitutes the largest GWAS for COVID-19 hospitalization in admixed Latin Americans conducted to date. This allowed to reveal novel risk loci and emphasize the need of considering the diversity of populations in genomic research.

Integrating Previous Suicide Attempts, Gender, and Age Into Suicide Risk Assessment Using Advanced Artificial Intelligence Models.

Objective: Suicide is a critical global health concern. Research indicates that generative artificial intelligence (GenAI) and large language models, such as generative pretrained transformer-3 (GPT-3) and GPT-4, can evaluate suicide risk comparably to experts, yet the criteria these models use are unclear. This study explores how variations in prompts, specifically regarding past suicide attempts, gender, and age, influence the risk assessments provided by ChatGPT-3 and ChatGPT-4.Methods: Using a controlled scenario based approach, 8 vignettes were created. Both ChatGPT-3.5 and ChatGPT 4 were used to predict the likelihood of serious suicide attempts, suicide attempts, and suicidal thoughts. A univariate 3-way analysis of variance was conducted to analyze the effects of the independent variables (previous suicide attempts, gender, and age) on the dependent variables (likelihood of serious suicide attempts, suicide attempts, and suicidal thoughts).Results: Both ChatGPT-3.5 and ChatGPT-4 recognized the importance of previous suicide attempts in predicting severe suicide risks and suicidal thoughts. ChatGPT-4 also identified gender differences, associating men with a higher risk, while both models disregarded age as a risk factor. Interaction analysis revealed that ChatGPT-3.5 associated past attempts with a higher likelihood of suicidal thoughts in men, whereas ChatGPT-4 showed an increased risk for women.Conclusions: The study highlights ChatGPT-3.5 and ChatGPT-4's potential in suicide risk evaluation, emphasizing the importance of prior attempts and gender, while noting differences in their handling of interactive effects and the negligible role of age. These findings reflect the complexity of GenAI decision-making. While promising for suicide risk assessment, these models require careful application due to limitations and real-world complexities.

Pelvic floor dysfunction in postpartum women: A cross-sectional study.

BACKGROUND: Pelvic floor dysfunction (PFD) is a disease of weakened pelvic floor support tissues, leading to changes in the pelvic organ position and function of pelvic organs, with long-term effects on women. This study aimed to assess pelvic floor function using electrophysiology and clinical symptoms, exploring the risk factors for PFD one month postpartum. METHODS: This cross-sectional study included 845 women from postpartum outpatient clinic of Nantong Affiliated Hospital from August 2019 to October 2021. Pelvic floor muscle strength was evaluated via pelvic floor surface electromyography. Clinical symptoms (urinary incontinence (UI) and pelvic organ prolapse) were diagnosed by gynecologists. Sociodemographic, pregnancy, and obstetrical data were obtained from self-reported questionnaires and electronic records. RESULTS: The study identified maternal age, parity, immigrant status, and economic income as factors were related to PFD. Gestational constipation increased the risk of abnormal resting muscle strength (OR:1.553, 95%CI: 1.022-2.359). Cesarean delivery was associated with higher rates of abnormal resting muscle strength than vaginal delivery (post-resting stage: OR, 2.712; 95% CI, 1.189-6.185), but a decreased incidence of UI (OR: 0.302; 95% CI, 0.117-0.782). Increased gestational weight gain was correlated with a greater risk of developing UI (OR:1.030, 95%CI: 1.002-1.058). Women with vaginal inflammation faced a higher risk of abnormal fast-twitch muscle (OR: 2.311, 95%CI: 1.125-4.748). CONCLUSIONS: In addition to uncontrollable factors like mode of delivery, age, and parity, interventions targeting weight gain and constipation during pregnancy and vaginal flora could mitigate the risks of PFD. Educational programs for pregnant women should emphasize a proper diet and lifestyle. For women with vaginal inflammation, clinical treatment should be carried out as soon as possible to avoid further aggravating the damage to the pelvic floor muscles.

Deciphering changes in the incidence of hemorrhagic stroke and cerebral venous sinus thrombosis during the coronavirus disease 2019 pandemic: A nationwide time-series correlation study.

INTRODUCTION: Hemorrhagic stroke and cerebral venous sinus thrombosis (CVST) are associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and vaccination. We aimed to investigate changes in the incidence of hemorrhagic stroke and CVST in South Korea before and during the coronavirus disease 2019 pandemic and the factors associated with these changes. MATERIALS AND METHODS: We conducted a nationwide time-series study using population-based databases between 2007 and 2022. The real-world and forecasted incidences of acute non-traumatic subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and CVST during the pandemic period (2020-2022) were estimated and compared with the pre-pandemic period (2007-2019). The prevalence of conventional risk factors was measured using time-series data. Finally, a time-series correlation analysis was performed to examine the temporal association between conventional risk factors, SARS-CoV-2 infection, and SARS-CoV-2 vaccination. RESULTS: The incidence of hemorrhagic stroke (SAH and ICH) was lower during the pandemic than during the pre-pandemic period. This observed decrease was associated with a reduction in the prevalence of conventional risk factors but not with SARS-CoV-2 infection or vaccination. The incidence of CVST was higher during the pandemic than during the pre-pandemic period, which may be temporally related to SARS-CoV-2 vaccination (Pearson correlation coefficient [r] = 0.349, P = 0.031). CONCLUSION: We report reassuring evidence of hemorrhagic stroke associated with SARS-CoV-2 infection and vaccination. However, awareness of CVST may be required for future vaccine rollouts and SARS-CoV-2 outbreaks.

Asymptomatic bacteriuria and its associated fetomaternal outcomes among pregnant women delivering at Bugando Medical Centre in Mwanza, Tanzania.

BACKGROUND: Asymptomatic bacteriuria (ASB) affects 23.9% of pregnant women globally and, if left untreated, can lead to adverse fetomaternal outcomes. In Tanzania, ASB prevalence has ranged from 13% to 17% over the past decade. Yet, its impact on fetomaternal outcomes remains unexplored, hindering the development of screening strategies, antimicrobial therapies, and preventive measures for this vulnerable population. METHODS: A cross-sectional analytical study was conducted on 1,093 pregnant women admitted for delivery at Bugando Medical Center (BMC) in Mwanza, Tanzania, from July to December 2022. Socio-demographic, obstetric, and clinical data were collected from the women, along with mid-stream urine samples for analysis. Fetomaternal outcomes were assessed within 72 hours after delivery. RESULTS: The median age of participants was 29 years (range: 15-45 years). ASB prevalence among pregnant women was 16.9% (185/1093), with a 95% CI of 14.6-19.3%. Risk factors for ASB included anemia (OR: 5.3; 95% CI = 3.7-8.2, p-value <0.001) and a history of antenatal care admission (OR 4.2; 95% CI = 2.9-6.1, p-value <0.001). Among all participants, 82 (7.5%), 65 (5.9%), 49 (4.5%), and 79 (7.2%) experienced pre-term labor (PTL), premature rupture of membrane (PROM), preeclampsia, and delivered newborns with low birthweight (LBW), respectively. Among the 185 patients with ASB, the respective proportions of PTL, PROM, preeclampsia, and LBW were 25.4%, 17.3%, 9.2%, and 12.4%. Multivariable logistic regression analysis revealed significant associations between ASB and PTL [OR (95% CI): 8.8 (5.5-14.5); p-value <0.001], PROM [OR (95% CI): 4.5 (2.5-8.0); p-value <0.001], and LBW [OR (95% CI): 2.0 (1.2-3.5); p-value = 0.011]. Escherichia coli (50.8%) and Klebsiella pneumoniae (14.05%) were the most common pathogens, with low resistance rates to nitrofurantoin, amoxicillin-clavulanate, and cephalosporins-antibiotics considered safe during pregnancy-ranging from 8.2% to 31.0%. CONCLUSION: The prevalence of ASB among pregnant women in Tanzania remains high and is associated with adverse fetomaternal outcomes. Integrating routine urine culture screening for all pregnant women, irrespective of symptoms, and providing specific antimicrobial therapies during antenatal care can help prevent adverse pregnancy outcomes.

High blood eosinophils predict the risk of COPD exacerbation: A systematic review and meta-analysis.

BACKGROUND: The association between blood eosinophils and COPD exacerbation has been controversial. This study aims to investigate whether high blood eosinophils predict the risk of COPD exacerbation across different thresholds and subgroups. METHODS: PubMed, Embase and Web of science were searched for randomized controlled trial (RCT) and observational studies regarding the relationship between blood eosinophils and COPD exacerbation. Pooled risk ratio (RR) for COPD exacerbation was calculated using the Mantel-Haenszel method with a random-effects model. RESULTS: A total of 21 studies (1 RCT and 20 observational studies) with 79868 participants were included. Thresholds of high blood eosinophils including absolute counts (200, 300 and 400 cell/µL) and percentages (2%, 3% and 4%) were analyzed respectively. Pooled analyses suggested that high blood eosinophils were significantly associated with increased risk of COPD exacerbation when using the thresholds of 300 cells/µL (RR 1.21, 95%CI 1.12-1.30, P <0.001, 16 studies), 400 cells/µL (RR 1.79, 95%CI 1.41-2.28, P <0.001, 3 studies), 2% (RR 1.26, 95%CI 1.02-1.55, P = 0.030, 10 studies) and 4% (RR 1.44, 95%CI 1.05-1.96, P = 0.022, 4 studies), but not 200 cells/µL and 3% (P>0.05). Moreover, high blood eosinophils contributed to moderate-severe exacerbation of COPD by the cutoffs of 300 cells/µL (RR 1.30, 95%CI 1.16-1.45, P<0.001, 11 studies) and 2% (RR 1.33, 95%CI 1.02-1.76, P = 0.037, 8 studies). In subgroup analyses, the pooled results further showed a significant association between high blood eosinophils (especially over 300 cells/µL) and risk of COPD exacerbation among patients from Europe and Asia, and whether with stable or exacerbation phase at baseline, and regardless of the follow-up time (≤ or > 1year). CONCLUSIONS: This study demonstrates that high blood eosinophils (over 300 cells/µL or 2%) could predict the risk of moderate-severe exacerbation of COPD in specific subgroups. However, large sample-sized, prospective, and well-designed studies are required to validate the present findings.

Factors associated with sexual violence against reproductive-age women in Ghana: A multilevel mixed-effects analysis.

BACKGROUND: Sexual violence against women is a pervasive public health challenge and human rights violation, with global prevalence rates of approximately one in three women affected, notably prevalent in African countries. Understanding its multifaceted determinants is crucial for developing targeted intervention strategies. Thus, this study aimed to investigate factors associated with sexual violence against reproductive-age ever-married women in Ghana. METHODS: A weighted sample of 3,816 reproductive-age ever-married women from the 2022 Ghana Demographic and Health Survey (DHS) was included. To accommodate the hierarchical nature of the DHS data and the binary outcome variable 'sexual violence', a multilevel mixed-effect logistic regression model was employed. The deviance value was utilized for selecting the best-fitted model. In the multivariable multilevel binary logistic regression analysis, adjusted odds ratios (AORs) along with their respective 95% confidence intervals (CIs) were utilized to gauge the association strength, with statistical significance set at a p-value < 0.05. RESULT: The prevalence of sexual violence was found to be 8.80% (95% CI: 7.94-9.74). Factors positively associated with sexual violence included women's decision-making autonomy (AOR = 1.39, 95% CI: 1.08-1.74), husband/partner's alcohol consumption (AOR = 3.88, 95% CI: 2.98-5.06), sex of household head (AOR = 1.31, 95% CI: 1.02-1.68), and justification of beating (AOR = 1.35, 95% CI: 1.01-1.81). Conversely, women's age showed a negative association with sexual violence (AOR = 0.68, 95% CI: 0.48-0.98). CONCLUSION: In conclusion, prioritizing initiatives that empower women in decision-making roles, provide support for those struggling with alcohol consumption, and raise awareness about its impact on interpersonal relationships and the risk of sexual violence is essential. Furthermore, addressing harmful gender norms, particularly those justifying violence, and considering demographic characteristics are vital components of comprehensive strategies to prevent and mitigate sexual violence.

Roles of low muscle strength and sarcopenic obesity on incident symptomatic knee osteoarthritis: A longitudinal cohort study.

OBJECTIVES: Sarcopenia is prevalent in middle to old age. We aimed to investigate the association between muscle strength and the incident knee osteoarthritis (OA). METHODS: 12,043 participants were collected from the China Health and Retirement Longitudinal Study. The effects of sarcopenic obesity (defined by obesity in combination with possible sarcopenia) on knee OA onset were calculated using Poisson regression models. Mediation analysis was fit to estimate mediating proportion of muscle strength on the association between obesity and incident knee OA. RESULTS: The study all enrolled 12,043 participants with 2,008 progressed to knee OA. Poisson analyses demonstrated causal association of general obesity (RR:1.23, 95% CI: 1.08 to 1.39) and abdominal obesity (RR:1.23, 95% CI: 1.11 to 1.35) with knee OA onset. For the risk of incident knee OA, participants with the highest level of normalized grip strength had a decreased risk of incident knee OA by 0.33 (RR:0.67, 95% CI: 0.60 to 0.75) times compared to the control group, and chair-rising time was associated with increased risk of incident knee OA by 0.65 (RR:1.65, 95% CI: 1.17 to 2.33) times. Sensitivity analysis identified similar results. Participants with sarcopenic obesity were about 2 times risk of incident knee OA than reference group. Normalized grip strength and chair-rising time mediated the association between obesity and incidence of knee OA. CONCLUSIONS: Sarcopenic obesity is correlated with an increased risk of knee OA. Muscle strength recovery may alleviate the risk of incident knee OA in middle to old age with obesity.

Ten-year trends in lipid management among patients after myocardial infarction in South Korea.

BACKGROUND: Dyslipidemia is an important risk factor for acute myocardial infarction. However, real-world data on its prevalence and lipid management trends for Korean patients with acute myocardial infarction are limited. This study aimed to determine the 10-year temporal trends in dyslipidemia prevalence and lipid management in this patient population. METHODS AND FINDINGS: The study used a merged database of two nationwide observational cohorts (2011-2020) that included 26,751 participants. The primary endpoints were the achievement rates of the (1) absolute low-density lipoprotein cholesterol (LDL-C) target of <70 mg/dL (<1.8 mmol/L), (2) relative LDL-C target reduction of >50% from the baseline, (3) absolute or relative LDL-C target (American target), and (4) both absolute and relative LDL-C targets (European target). The dyslipidemia prevalence increased from 11.1% to 17.1%, whereas the statin prescription rate increased from 92.9% to 97.0% from 2011 to 2020. The rate of high-intensity statin use increased from 12.80% in 2012 to 69.30% in 2020. The rate of ezetimibe use increased from 4.50% in 2016 to 22.50% in 2020. The high-intensity statin and ezetimibe prescription rates (0.20% to 9.30% from 2016 to 2020) increased gradually. The absolute and relative LDL-C target achievement rates increased from 41.4% and 20.8% in 2012 to 62.5% and 39.5% in 2019, respectively. The American (45.7% in 2012 to 68.6% in 2019) and European (16.5% in 2012 to 33.8% in 2019) target achievement rates also increased. CONCLUSIONS: The adoption of lipid management guidelines in clinical practice has improved. However, continued efforts are needed to reduce the risk of recurrent ischemic events.

Behavioral Risk Profiles of Stroke Survivors Among US Adults: Geographic Differences Between Stroke Belt and Non-Stroke Belt States.

Introduction: Stroke, a leading cause of illness, death, and long-term disability in the US, presents with significant disparities across the country, most notably in southeastern states comprising the "Stroke Belt." This study intended to identify differences between Stroke Belt states (SBS) and non-Stroke Belt states (NSBS) in terms of prevalence of stroke, sociodemographic and behavioral risk factors, and health-related quality of life (HRQOL). Methods: We analyzed data from the 2019 Behavioral Risk Factor Surveillance System to compare demographic characteristics, risk factors, physical activity adherence, functional independence, and HRQOL among stroke survivors in SBS and NSBS. Results: Of 18,745 stroke survivors, 4,272 were from SBS and 14,473 were from NSBS. Stroke was more prevalent in SBS (odds ratio [OR] = 1.39; 95% CI, 1.35-1.44; P < .001), with significant differences by age, sex, and race and ethnicity, except for Hispanic ethnicity. Selected stroke risk factors were more common in every category in SBS. Stroke survivors in SBS were less likely to meet physical activity guidelines for aerobic (OR = 0.77; 95% CI, 0.69-0.86; P < .001) and aerobic and strengthening combined (OR = 0.77; 95% CI, 0.70-0.86; P < .001) activities. Stroke survivors in SBS were more likely to not meet either physical activity guideline (OR = 1.31; 95% CI, 1.22-1.41; P < .001). Conclusions: Living in SBS significantly increased the odds of stroke occurrence. Stroke survivors from SBS reported lower HRQOL and insufficient physical activity as well as lower functional independence. Specific strategies are needed for residents of SBS, with a focus on policies and primary and secondary prevention practices across healthcare professions.
