RESUMO
BACKGROUND: Heavy menstrual bleeding (HMB) is a common menstrual disorder associated with multiple risk factors of cardiovascular disease (CVD) in women. In addition, HMB is often present with irregular menstruation (IM) which is a risk factor for CVD outcomes. However, the relationship between HMB and CVD outcomes is unexplored in the presence or absence of IM. We determined the association of HMB with multiple CVD outcomes using a nationally representative sample of female hospitalizations in the US. METHODS: All hospitalizations of females with HMB diagnosis and normal menstrual cycles from ages of 18 to 70 years were extracted from the National Inpatient Sample Database, 2017. The HMB was defined using the International Classification of Diseases (ICD)-10 for excessive and frequent menstruation bleeding and included any current or history of HMB diagnosis. Outcomes including major adverse cardiovascular events (MACE), coronary heart disease (CHD), stroke, heart failure (HF), atrial fibrillation (AF) or arrhythmia, myocardial infarction (MI), and diabetes (DM) were defined using ICD-10 codes. Adjusted logistic regression and prosperity scores-matched logistic regression analyses were conducted to summarize adjusted associations with an odds ratio (OR) and a 95% confidence interval (CI). RESULTS: Among 2,430,851 hospitalizations, HMB was observed in 7762 (0.68%) females with age ≤ 40 years and 11,164 (0.86%) females with age > 40 years. Among hospitalizations with age ≤ 40 years, HMB was significantly associated with increased odds of CVD outcomes including MACE (OR = 1.61; 95% CI: 1.25, 2.08), CHD (OR = 1.72; 95% CI: 1.10, 2.71), stroke (OR = 1.95; 95% CI: 1.12, 3.40), HF (OR = 1.53; 95% CI: 1.15, 2.03), and AF/arrhythmia (OR = 1.84; 95% CI: 1.34, 2.54). These associations were confirmed in multiple sensitivity analyses. In contrast, HMB was not robustly associated with CVD events among hospitalizations of women with age > 40 years. HMB without IM was strongly associated with DM, HF, AF, and MACE outcomes while HMB with IM was strongly associated with CHD and AF outcomes in hospitalizations of young women. CONCLUSIONS: HMB is associated with CVD events among US hospitalizations of young women. A routine investigation and screening of menstrual disorders, especially HMB, is useful for CVD risk stratification and management in young women.

PURPOSE OF REVIEW: Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder in women of reproductive age. It has been associated with metabolic, reproductive, and psychiatric disorders. Despite its association with insulin resistance (IR) and cardiovascular disease (CVD) risk factors, the association between PCOS and CVD outcomes has been conflicting. This review reports the updated evidence between PCOS, insulin resistance, and CVD events. RECENT FINDINGS: IR is highly prevalent occurring in 50 to 95% of general and obese PCOS women. The etiology of PCOS involves IR and hyperandrogenism, which lead to CVD risk factors, subclinical CVD, and CVD outcomes. Multiple studies including meta-analysis confirmed a strong association between PCOS and CVD events including ischemic heart disease, stroke, atrial fibrillation, and diabetes, particularly among premenopausal women, and these associations were mediated by metabolic abnormalities. PCOS is highly familial and has substantial CVD risk and transgenerational effects regardless of obesity. A personalized approach to the CVD risk assessment and management of symptom manifestations should be conducted according to its phenotypes. Lifestyle modifications and reduction in environmental stressors should be encouraged for CVD prevention among PCOS women.

PURPOSE OF REVIEW: Although environmental exposure such as air pollution is detrimental to cardiovascular disease (CVD), the effects of different air pollutants on different CVD endpoints produced variable findings. We provide updated evidence between air pollutants and CVD outcomes including mitigation strategies with meta-analytic evidence. RECENT FINDINGS: An increased exposure to any class of air pollutants including particulate matter (PM), gas, toxic metals, and disruptive chemicals has been associated with CVD events. Exposure to PM < 2.5 µm has been consistently associated with most heart diseases and stroke as well as CVDs among at-risk individuals. Despite this, there is no clinical approach available for systemic evaluation of air pollution exposure and management. A large number of epidemiological evidence clearly suggests the importance of air pollution prevention and control for reducing the risk of CVDs and mortality. Cost-effective and feasible strategies for air pollution monitoring, screening, and necessary interventions are urgently required among at-risk populations and those living or working, or frequently commuting in polluted areas.

PURPOSE OF REVIEW: Diet and lifestyle patterns are considered major contributory factors for cardiovascular disease (CVD) and mortality. In particular, consuming a diet higher in carbohydrates (not inclusive of fruits and vegetables, but more processed carbohydrates) has been associated with metabolic abnormalities that subsequently may increase the risk of CVD and related mortality. Glycemic index (GI) and glycemic load (GL) are values given to foods based on how fast the body converts carbohydrates into glucose also referred to as the glycemic burden of carbohydrates from foods. Conflicting associations of how high GI and GL influence CVDs have been observed even in high-quality meta-analysis studies. We synthesize and report the associations of high GI and GL with various CVDs by sex, obesity, and geographical locations using an updated review of meta-analysis and observational studies. RECENT FINDINGS: We identified high GI or high GL is associated with an increased risk of CVD events including diabetes (DM), metabolic syndrome (MS), coronary heart disease (CHD), stroke, and stroke mortality in the general population, and the risk of CVD outcomes appears to be stratified by sex, obesity status, and preexisting CVD. Both high GI and GL are associated with DM and CHD in the general population. However, high GI is strongly associated with DM/MS, while high GL is strongly associated with an increased risk of CHD in females. In addition, high GL is also associated with incident stroke, and appears to be associated with CVD mortality in subjects with preexisting CVD or high BMI and all-cause mortality in non-obese DM subjects. However, high GI appears to be associated with CVD or all-cause mortality only in females without CVD. High GI/GL is an important risk factor for CVD outcomes in the general population. High GI seems to be markedly associated with DM/MS, and it may enhance the risk of CVD or all-cause mortality in both sexes and predominately females. Although both high GI and high GL are risk factors for CHD in females, high GL is associated with CVD outcomes in at-risk populations for CVD. These data suggest that while high GI increases the propensity of CVD risk factors and mortality in healthy individuals, high GL contributes to the risk of severe heart diseases including CVD or all-cause mortality, particularly in at-risk populations. These data indicate dietary interventions designed for focusing carbohydrate quality by lowering both GI and GL are recommended for preventing CVD outcomes across all populations.

BACKGROUND: Coronavirus disease (COVID-19) has been associated with adverse pregnancy outcomes. Due to the lack of effective treatments for COVID-19, it becomes imperative to assess the geographical differences and trends in the current clinical care and outcomes of COVID-19 in pregnant women. METHODS: A PubMed search was performed to screen articles reporting therapeutics and outcomes of confirmed COVID-19 in pregnant women prior to August 27, 2020. We performed searches, quality assessments of eligible studies, extracted and reported data according to PRISMA guidelines. Meta-analyses and cumulative meta-analyses of proportions were performed for estimating each outcome and their pattern over time respectively. RESULTS: One thousand two hundred thirty nine pregnant women with COVID-19 from 66 studies were analyzed. In case series analysis reflecting average-risk patients, the proportion of oxygen support, antibiotics, antivirals, and plasma therapy administration except for hydroxychloroquine was substantially higher in Asian studies (55, 78, 80, 6, and 0%) compared to the US (7, 1, 12, 0, and 7%) or European (33, 12, 14, 1, and 26%) studies, respectively. The highest preterm birth and the average length of hospital stay (35%, 11.9 days) were estimated in Asian studies compared to the US studies (13%, 9.4 days) and European studies (29%, 7.3 days), respectively. Even in case reports reflecting severe cases, the use of antivirals and antibiotics was higher in Asian studies compared to the US, Latin American, and European studies. A significant decline in the use of most therapeutics along with adverse outcomes of COVID-19 in pregnant women was observed. CONCLUSIONS: Geographical differences in therapeutic practice of COVID-19 were observed with differential rates of maternal and clinical outcomes. Minimizing the use of some therapeutics particularly antibiotics, antivirals, oxygen therapy, immunosuppressants, and hydroxychloroquine by risk stratification and careful consideration may further improve maternal and clinical outcomes.

PURPOSE OF REVIEW: The prevalence of obesity and cardiovascular disease (CVD) has been increasing worldwide. Studies examining the association between adiposity and CVD outcomes have produced conflicting findings. The interplay between obesity and CVD outcomes in the general population and in specific subpopulations is complex and requires further elucidation. RECENT FINDINGS: We report updated evidence on the association between obesity and CVD events through a review of meta-analysis studies. This review identified that obesity or high body mass index (BMI) was associated with an increased risk of CVD events, including mortality, in the general population and that cardiac respiratory fitness (CRF) and metabolic health status appear to stratify the risk of CVD outcomes. In patients with diabetes, hypertension, or coronary artery disease, mortality displayed a U-shaped association with BMI. This U-shaped association may result from the effect of unintentional weight loss or medication use. By contrast, patients with other severe heart diseases or undergoing cardiac surgery displayed a reverse J-shaped association suggesting the highest mortality associated with low BMI. In these conditions, a prolonged intensive medication use might have attenuated the risk of mortality associated with high BMI. For the general population, a large body of evidence points to the importance of obesity prevention and maintenance of a healthy weight. However, for those with diagnosed cardiovascular diseases or diabetes, the relationship between BMI and cardiovascular outcomes is more complex and varies with the type of disease. More studies are needed to define how heterogeneity in the longitudinal changes in BMI affects mortality, especially in patients with severe heart diseases or going under cardiac surgery, in order to target subgroups for tailored interventions. Interventions for managing body weight, in conjunction with improving CRF and metabolic health status and avoiding unintentional weight loss, should be used to improve CVD outcomes.

Background: Sex hormones play a critical role in sex differences and cardiovascular disease risk associated with metabolic syndrome (MS) and inflammation. However, the associations of sex hormone ratios with metabolic and inflammatory markers are unclear according to sex and age differences. We evaluated the associations of sex hormone ratios with MS and inflammation among males and females. Methods: A retrospective cross-sectional study was conducted by including all adults from the National Health and Nutrition Examination Survey cycles 2013-2016 and excluding any pregnant women, heart disease, diabetes, and those currently taking insulin. MS was defined using the National Cholesterol Education Program criteria and a high-sensitivity C-reactive protein (CRP) level>3 mg/L was defined as a high CRP. Measures of MS components and CRP concentrations were also analyzed. The primary exposures were testosterone to estradiol (excess androgen index), testosterone to sex hormone-binding globulin (free androgen index), and estradiol to sex hormone-binding globulin (free estradiol index). The adjusted associations were summarized with a relative risk (RR) and 95% confidence interval (CI). Results: This study included 9167 subjects with 4360 males and 4807 females. Increases in free estradiol index were positively associated with MS (RR=1.48; 95%CI: 1.39, 1.58; RR=1.31; 95%CI: 1.22, 1.40) and high CRP (RR=1.49; 95%CI: 1.25, 1.77; RR=1.26; 95%CI: 1.06, 1.50) in men with age<50 years and age≥50 years, respectively. Similarly, higher free estradiol index was also robustly associated with increased prevalence of MS (RR=1.22; 95%CI: 1.15, 1.28) and high CRP (RR=1.68; 95%CI: 1.48, 1.90) in women with age ≥50 years. Among women with age<50 years, a higher free androgen index was associated with MS (RR=1.34; 95%CI: 1.25, 1.42) and high CRP (RR=1.13; 95%CI: 1.02, 1.25). These associations were unchanged even after adjusting for all sex hormones. Conclusion: Free estradiol index was consistently and positively associated with MS and high CRP in males of all ages and older females. Free androgen index was positively associated with MS and high CRP in females with age<50 years.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disorder characterized by a wide range of symptoms related to ovulatory dysfunction and androgen overproduction. Although PCOS is associated with multiple cardiovascular disease (CVD)-risk factors, previous studies have reported controversial associations between PCOS and different types of CVD events. We sought to determine the association of PCOS with various CVD outcomes among hospitalized women. METHODS: All women hospitalizations between the ages of 15 and 65 years recorded in the National Inpatient Sample database, 2017 were analyzed with sampling-weighted logistic regression analysis. The International Classification of Diseases, 10th revision, codes were used to define outcomes including composite CVD, major adverse cardiovascular events (MACEs), coronary heart disease (CHD), stroke/cerebrovascular accident (CVA), heart failure (HF), arterial fibrillation (AF) or arrhythmia, pulmonary heart disease (PHD), myocardial infarction, cardiac arrest, and diabetes. RESULTS: Among the total hospitalizations of women, 13 896 (0.64) had a PCOS diagnosis. Polycystic ovary syndrome was found to be associated with most CVD outcomes, including composite CVD (adjusted odds ratio [aOR] = 1.73, 95% CI, 1.55-1.93, P < .001), MACE (aOR = 1.31, 95% CI, 1.12-1.53, P < .001), CHD (aOR = 1.65, 95% CI, 1.35-2.01, P < .001), stroke/CVA (aOR = 1.46, 95% CI, 1.08-1.98, P = .014), HF (aOR = 1.30, 95% CI, 1.07-1.57, P = .007), AF/arrhythmia (aOR = 2.20, 95% CI, 1.88-2.57, P < .001), and PHD (aOR = 1.58, 95% CI, 1.23-2.03, P < .001) among hospitalized women with an age of ≤40 years. However, the associations between PCOS and CVD outcomes were mediated by obesity and metabolic syndrome conditions. CONCLUSIONS: Polycystic ovary syndrome is associated with CVD events and the association is mediated by obesity and metabolic syndrome conditions, particularly among hospitalized women aged ≤40 years in the United States.

OBJECTIVE: Determine if providing basic contraceptive counseling during prenatal visits increases pregnant Hispanic women's acceptance of immediate postpartum long-acting reversible contraception (LARC). STUDY DESIGN: Respondents completed a short survey consisting of demographic information, an acculturation scale, and perceptions of immediate postpartum LARC use. After reading a brief educational excerpt on intrauterine devices (IUDs) and the subdermal contraceptive implant, LARC acceptability was reassessed. The study included 198 Hispanic women, ages 14 and older, in the 2nd or 3rd trimester of pregnancy receiving care at an academic practice along the United States-Mexico border in West Texas. Analysis was performed using a McNemar test, univariate and multivariable relative risk (RR) regression. RESULTS: Prior to an educational intervention, 34.5% of respondents indicated that they were planning to use immediate postpartum LARC. Following the educational intervention, 74.5% of respondents indicated they would consider a postpartum LARC. The pre/post comparison on the intent to use postpartum LARC showed that a significant number of respondents changed their intention to use LARC after reading the educational intervention (RR= 2.54, p<0.0001). LARC acceptability was high among single women, those less than 25-years-old, women with current unintended pregnancies, and women using a contraceptive method that failed when they became pregnant. CONCLUSION: In communities with a high proportion of Hispanic women, postpartum contraceptive counseling is crucial for patient education and family planning. When women are provided with brief, structured contraceptive counseling during prenatal visits, they are more willing to consider use of an immediate postpartum LARC for their future family planning.

Importance: Obesity and metabolic syndrome are highly prevalent among the US population and are associated with the dysregulation of sex hormones. An increase in obesity and metabolic syndrome may also be associated with exposure to phthalates. The association of exposure to phthalate metabolites with sex hormones and metabolic health has been understudied in the female population. Objective: To evaluate the association between exposure to common phthalate metabolites with total testosterone (TT) levels, sex hormone-binding globulin (SHBG) levels, obesity, and metabolic syndrome among women. Design, Setting, and Participants: This cross-sectional study used data collected from the National Health and Nutrition Examination Survey during 2013 to 2016. Female participants aged 15 years or older with urinary profiles containing common phthalate metabolites were included in this study. Statistical analyses were performed from March 15, 2021, to April 30, 2022. Exposures: Urinary concentrations of phthalate metabolites were classified into tertiles, and the lowest tertile was used as a reference category. The concentrations of phthalate metabolites and their composite scores based on clustering were also used in the analysis. Main Outcomes and Measures: Serum concentrations of TT and SHBG were dichotomized into high TT levels (>46 ng/dL [to convert to nanomoles per liter, multiply by 0.0347] for age <50 years and >32 ng/dL for age ≥50 years) and low SHBG levels (<2.85 µg/mL [to convert to nanomoles per liter, multiply by 10.53]) as established for the female population. Obesity was defined as a body mass index of 30 or more (calculated as weight in kilograms divided by height in meters squared), and metabolic syndrome was defined using the National Cholesterol Education Program criteria. The serum concentrations of TT and SHBG were also included in the validation analyses. Modified Poisson models were used to estimate the adjusted relative risk (RR) with 95% CIs for the associations. Results: Among the 2004 women included in this study, the mean (SD) age was 46.6 (18.5) years (14.7% Hispanic participants, 62.7% non-Hispanic White participants, and 13.2% non-Hispanic Black participants; 17.4% of participants were born outside the US [weighted percentages]; 230 (11.8%) had high TT levels, 210 (10.4%) had low SHBG levels, 825 (39.8%) had obesity, and 965 (45.5%) had metabolic syndrome (weighted percentages). Of the 13 phthalate metabolites, 8 had the highest tertile level greater than 6.2 ng/mL (range, 0.5-75.2 ng/mL). High levels of exposure to mono(2-ethyl-5-carboxypentyl) phthalate (RR, 1.84 [95% CI, 1.33-2.54]), mono(2-ethyl-5-oxohexyl) phthalate (RR, 1.77 [95% CI, 1.21-2.59]), mono(2-ethyl-5-hydroxyhexyl) phthalate (RR, 1.94 [95% CI, 1.34-2.81]), and monobenzyl phthalate (RR, 1.75 [95% CI, 1.21-2.54]) were associated with low SHBG levels but not with high TT levels. High levels of exposure to some of these metabolites were also associated with obesity and metabolic syndrome. Most associations were specific to premenopausal or postmenopausal women. Conclusions and Relevance: In this cross-sectional study, exposure to certain phthalate metabolites could be associated with low SHBG levels, obesity, and metabolic syndrome depending on menopausal status.

Dietary patterns contribute to cancer risk. Separately, microbial factors influence the development of several cancers. However, the interaction of diet and the microbiome and their joint contribution to cancer treatment response needs more research. The microbiome significantly impacts drug metabolism, immune activation, and response to immunotherapy. One of the critical factors affecting the microbiome structure and function is diet. Data demonstrate that the diet and microbiome composition affects the immune response. Moreover, malnutrition is a significant confounder to cancer therapy response. There is little understanding of the interaction of malnutrition with the microbiome in the context of cancer. This review aims to address the current knowledge of dietary intake patterns and malnutrition among cancer patients and the impact on treatment outcomes. Second, this review will provide evidence linking the microbiome to cancer treatment response and provide evidence of the potentially strong effect that diet could have on this interaction. This review will formulate critical questions that will need further research to understand the diet-microbiome relationship in cancer treatment response and directions for future research to guide us to precision nutrition therapy to improve cancer outcomes.

Growth factors (GF) regulate normal development to cancer progression. GFs interact with extracellular matrix (ECM) biomolecules, such as heparin sulfate (HS) glycosaminoglycan (GAG), to enhance their stability and angiogenic signaling. Biomaterials that modulate GF activity by mimicking interactions observed in the native ECM could be designed as an effective treatment strategy. However, these materials failed to attenuate angiogenic signaling site-specifically without sparing normal tissues. In this work, we investigated the effect of a GAG-based biomaterial, which binds to the tumor endothelial cells (TEC), on the interaction among vascular endothelial growth factor (VEGF), its receptors-VEGFR2 and HS-and angiogenesis. Heparin-bile acid based conjugates, as ECM-mimicking component, were synthesized to selectively target the TEC marker doppel and doppel/VEGFR2 axis. The most effective compound LHbisD4 (low molecular weight heparin conjugated with 4 molecules of dimeric dexocholic acid) reduced tumor volume concentrated over doppel-expressing EC, and decreased tumor-interstitial VEGF without affecting its plasma concentration. Doppel-destined LHbisD4 captured VEGF, formed an intermediate complex with doppel, VEGFR2, and VEGF but did not induce active VEGFR2 dimerization, and competitively inhibited HS for VEGF binding. We thus show that GAG-based materials can be designed to imitate and leverage to control tumor microenvironment via bio-inspired interactions.

OBJECTIVE: Hyperandrogenism in females leads to multiple endocrine and metabolic disorders including polycystic ovary syndrome (PCOS) that yields adverse health outcomes across all ages. We sought to estimate the prevalence of hyperandrogenemia and at-risk hyperandrogenism among the US females of different age groups, racial/ethnic, and metabolic characteristics. MATERIALS AND METHODS: A retrospective population-based cross-sectional study of females 6 years or older having serum testosterone measures using the National Health and Nutrition Examination Surveys, 2013-2016 was conducted. Age-appropriate thresholds as per assay methods were used for evaluating high total testosterone, low sex hormone binding globulin (SHBG), and high free androgen index (FAI) levels. The weighted analysis was performed to estimate prevalence and 95 % confidence interval (CI). RESULTS: The prevalence of at-risk hyperandrogenism was estimated as 19.8 % (95 %CI: 18.6 %, 21.2 %) in the overall sample, 11.8 % (95 %CI: 9.5 %, 14.5 %) in prepubertal, 20.5 % (95 %CI: 18.9 %, 22.2 %) in premenopausal, and 21.1 % (95 %CI: 18.7 %-23.7 %) in postmenopausal females with considerable heterogeneity by racial/ethnic and metabolic characteristics. In the entire sample, hyperandrogenemia was estimated as 10.4 % and 4.3 % using total testosterone and FAI respectively while 10.7 % cases had a low SHBG. CONCLUSIONS: At-risk hyperandrogenism is equally prevalent in premenopausal and postmenopausal women with a considerable amount in prepubertal females and varied by racial/ethnic groups depending on specific ages. Regular screening of hyperandrogenism using SHBG and total testosterone measures among at-risk subjects for specific ages is critical for treating and preventing adverse consequences of abnormal hormonal parameters.

Polycystic ovary syndrome (PCOS) affects several reproductive and endocrine features in females and has a poorly understood etiology. Treatment strategies for PCOS are limited and are based primarily on diet and nutrient supplementation. Recent studies have recommended some nutrients such as vitamins, minerals and vitamin-like nutrients for the therapy for PCOS. Therefore, it is claimed that the cause of PCOS could be vitamin or mineral deficiency. This review provides a narrative on the effect of nutritional supplementation on oxidative stress induced in PCOS. Oxidative stress plays a formative role in PCOS pathophysiology. This article reviews oxidative stress, its markers, nutritional supplementation and clinical studies. We also aim to show the effect of nutritional supplementation on genes affecting hormonal and glucose-mediated pathways.

Several comorbidities have been shown to be associated with coronavirus disease 2019 (COVID-19) related severity and mortality. However, considerable variation in the prevalence estimates of comorbidities and their effects on COVID-19 morbidity and mortality have been observed in prior studies. This systematic review and meta-analysis aimed to determine geographical, age, and gender related differences in the prevalence of comorbidities and associated severity and mortality rates among COVID-19 patients. We conducted a search using PubMed, Scopus, and EMBASE to include all COVID-19 studies published between January 1st, 2020 to July 24th, 2020 reporting comorbidities with severity or mortality. We included studies reporting the confirmed diagnosis of COVID-19 on human patients that also provided information on comorbidities or disease outcomes. We used DerSimonian and Laird random effects method for calculating estimates. Of 120 studies with 125,446 patients, the most prevalent comorbidity was hypertension (32%), obesity (25%), diabetes (18%), and cardiovascular disease (16%) while chronic kidney or other renal diseases (51%, 44%), cerebrovascular accident (43%, 44%), and cardiovascular disease (44%, 40%) patients had more COVID-19 severity and mortality respectively. Considerable variation in the prevalence of comorbidities and associated disease severity and mortality in different geographic regions was observed. The highest mortality was observed in studies with Latin American and European patients with any medical condition, mostly older adults (≥ 65 years), and predominantly male patients. Although the US studies observed the highest prevalence of comorbidities in COVID-19 patients, the severity of COVID-19 among each comorbid condition was highest in Asian studies whereas the mortality was highest in the European and Latin American countries. Risk stratification and effective control strategies for the COVID-19 should be done according to comorbidities, age, and gender differences specific to geographical location.

There is emerging evidence demonstrating an association between maternal polycystic ovary syndrome (PCOS) and autism spectrum disorder (ASD) in children, however, the cumulative effect of maternal PCOS on the development of ASD or other neuropsychiatry disorders (NPD) in children and separately for males and females has not been examined. We sought to systematically evaluate the influence of maternal PCOS on a wide range of NPD including ASD, attention deficit hyperactivity disorder (ADHD), chronic tic disorder (CDT), other behavior disorders, anxiety, depression, bipolar disorder, schizophrenia in children as well as in women of reproductive age only. We queried electronic databases including PubMed, EMBASE, and Google Scholar, until March 2021. We used DerSimonian and Laird (D-L) random effects method to compute pooled effect size in terms of odds ratio (OR). Nineteen studies (1667851 mothers, 2260622 children) were included in this study. Mothers with PCOS had an increased odds of children diagnosed with ASD (OR = 1.40, p < 0.001), ADHD (OR = 1.42, p < 0.001), CTD (OR = 1.44, p = 0.001), anxiety (OR = 1.33, p < 0.001), as well as other behavioral symptoms (OR = 1.45, p < 0.001) in the adjusted analysis. The association between maternal PCOS and ASD (OR: 1.43 vs. 1.66), ADHD (OR: 1.39 vs. 1.54), and CTD (OR: 1.42 vs. 1.51) was found to be significantly consistent between males and females, respectively. Our data do not suggest increased fetal testosterone exposure is associated with increased autistic traits in children. However, PCOS was significantly associated with increased odds of a wide range of NPD in women themselves. Maternal PCOS is a risk factor for various NPD with a similar extent in their children regardless of their underlying comorbidities. Managing PCOS is essential for women's health as well as for their children's health. More research is needed to determine the mechanisms and links between maternal PCOS and NPD in children.

Diffuse esophageal spasm, also known as distal esophageal spasm (DES), is a rare motility disorder among the population with symptomatic motility disorders. This disorder is most commonly reported in females, with a median age of 60 years. Multiple therapeutic options have been developed for the treatment of DES. There has been limited research regarding the use of peppermint oil in the treatment of DES. Here, we discuss the interesting case of an elderly female patient who received symptomatic relief from peppermint oil.
RESUMO
Acute liver failure is a rare, life-threatening illness accounting for about 7% of all liver-related deaths. Patients with acute liver failure are managed with supportive care initially, and if supportive care fails, liver transplantation is the definitive option for eligible candidates in liver failure. N-acetyl cysteine (NAC) has a well-established role in acetaminophen-induced liver failure and has been reported to reduce mortality in these patients. It has also been reported to provide benefit in non-acetaminophen-induced liver failure secondary to infection, drugs, and toxins. Here we report an interesting case of NAC use in an elderly patient with shock liver secondary to severe sepsis in whom liver transplantation was not an option.
RESUMO
OBJECTIVE: Coronavirus disease 2019 (COVID-19) has become a global pandemic and may adversely affect pregnancy outcomes. We estimated the adverse maternal and neonatal characteristics and outcomes among COVID-19 infected women and determined heterogeneity in the estimates and associated factors. STUDY DESIGNS: PubMed search was performed of confirmed COVID-19 pregnant cases and related outcomes were ascertained prior to July 8, 2020, in this systematic review and meta-analysis. Studies reporting premature birth, low birth weight, COVID-19 infection in neonates, or mode of delivery status were included in the study. Two investigators independently performed searches, assessed quality of eligible studies as per the Cochrane handbook recommendations, extracted and reported data according to PRISMA guidelines. Pooled proportions of maternal and neonatal outcomes were estimated using meta-analyses for studies with varying sample sizes while a systematic review with descriptive data analysis was performed for case report studies. Maternal and neonatal outcomes included C-section, premature birth, low birth weight, adverse pregnancy events and COVID transmission in neonates. RESULTS: A total of 790 COVID-19 positive females and 548 neonates from 61 studies were analyzed. The rates of C-section, premature birth, low birth weight, and adverse pregnancy events were estimated as 72 %, 23 %, 7 %, and 27 % respectively. In the heterogeneity analysis, the rate of C-section was substantially higher in Chinese studies (91 %) compared to the US (40 %) or European (38 %) studies. The rates of preterm birth and adverse pregnancy events were also lowest in the US studies (12 %, 15 %) compared to Chinese (17 %, 21 %), and European studies (19 %, 19 %). In case reports, the rates of C-section, preterm birth, and low birth weight were estimated as 69 %, 56 %, and 35 %, respectively. Adverse pregnancy outcomes were associated with infection acquired at early gestational ages, more symptomatic presentation, myalgia symptom at presentation, and use of oxygen support therapy. CONCLUSIONS: Adverse pregnancy outcomes were prevalent in COVID-19 infected females and varied by location, type, and size of the studies. Regular screening and early detection of COVID-19 in pregnant women may provide more favorable outcomes.

Tangential excision and autologous split-thickness skin grafting is the standard management of the burn wound, but autograft has limitation of donor-site availability and morbidity. Human skin allograft is an alternate option of wound coverage when autograft is not available. Various synthetic skin substitute dressings are now available in the market, and thus use of human skin allograft has decreased. This case report explores the role of human skin allograft in burn wound management. Allograft facilitates excision of burn wounds during acute phase of burn injury in pediatric patients. It is cost-effective, reduces pain and risk of infection, and avoids frequent dressing changes. Availability of allograft and risk of infection are the two main constraints in its regular use.
