Summary: Background: Hyperemesis gravidarum (HG) is the most widespread reason for admission to the hospital during the first half of pregnancy. HG etiology is not clear in many cases. However, maternal body composition and pre-pregnancy diet are suggested as possible factors. This hospital-based case-control study aims to determine the link between the Mediterranean diet score (MDS) and pre-pregnancy anthropometric indicators with Hyperemesis gravidarum. Methods: A total of 45 women with incident HG and 126 controls were entered into this case-control study between April 2020 and June 2021. A repeatable and accurate 168-item semi-quantitative food frequency questionnaire was used to define the MDS. The association between MDS and HG odds was examined through adjustment by possible confounders by the estimation of multivariate regression models. Results: The median (interquartile range) pre-pregnancy body mass index of participants was 22.7 (21.7–25.9) and 22.9 (21.4–25) Kg/m2 in cases and controls, respectively (P=0.284). The adjusted analyses found that the MDS was associated with a 25% reduced odds of HG (odds ratio (OR): 0.75, 95% confidence interval (95%CI): 0.24–0.91). Body mass index and waist circumference before pregnancy were not significantly associated with HG odds in both regression models. Conclusions: The odds of HG during pregnancy are lower in women with a higher MDS before pregnancy. Also, a high intake of fruits and nuts, vegetables, legumes, and fish before pregnancy is liked with a lower HG odds.

Abstract Background and Aims Targeted research on physiological and psychological changes during menopause is crucial. Most studies have prioritized the investigation of psychological disorders during menopause, with a limited comparison of mental health among women in the various stages surrounding menopause. This study aims to explore the difference in depression and anxiety prevalence between women in premenopausal and menopause. Methods This cross‐sectional study was conducted on 242 female participants referred to Imam Hossein (AS) Educational and Therapeutic Hospital affiliated with Shahid Beheshti University of Medical Sciences. These 242 individuals were selected through accessible sampling. 122 individuals were placed in the menopausal group and 120 individuals in the premenopausal group. First, the medical history of all participants was taken, and then the Beck questionnaire was administered to examine the levels of depression and anxiety. The association between the occurrence and severity of depression and anxiety in menopausal and premenopausal groups was statistically analyzed. Results In this study, the age range of the participants was 45−70, the overall prevalence of depression was estimated to be 33.5% and the overall prevalence of anxiety was estimated to be 54.2%. The prevalence of depression was 30.2% and 36.6% in the menopausal and premenopausal groups, respectively. The prevalence of anxiety was estimated to be 52.5% and 55.7% in the menopausal and premenopausal groups, respectively. No significant difference was observed between the two groups in terms of the occurrence and severity of depression and anxiety. Conclusion our study found a higher incidence of depression during premenopause compared to menopause, possibly due to greater hormonal fluctuations. Despite this, there wasn't a significant confirmation of this hypothesis compared to other groups. Nonetheless, there's a higher prevalence of depression and anxiety among premenopausal women, emphasizing the need for screening and intervention, such as hormone therapy, to prevent severe outcomes.

Background and aimsDifferent factors, such as environmental, epigenetic, genetic and immunological, have been identified as potential risks for developing endometriosis. However, the correlation between dietary patterns and endometriosis is currently unknown. The aim of this study was to explore the potential link between fertility diet score and the odds of endometriosis.MethodsThis study was a hospital-based case–control study that took place in a gynecology clinic in Tehran, Iran, between February 2021 and January 2022. A total of 107 newly diagnosed endometriosis cases and 210 controls were included. The participants' habitual diets were evaluated using a food frequency questionnaire, and their fertility diet score was estimated using a point system based on Chavarro et al.'s criteria. The logistic regression was utilized to calculate the odds ratios (OR) with 95% confidence intervals (CIs).ResultsThe study found that women who adherence to fertility diet have a lower odds of endometriosis. This was observed in both the base model and the adjusted model, with a significant decrease in odds of endometriosis by 66% (OR = 0.44, 95%CI = 0.27–0.71, p = 0.001) and 54% (aOR = 0.46, 95%CI = 0.23–0.90, p = 0.022), respectively. Additionally, consuming vegetable proteins and multivitamins were also associated with lower odds of endometriosis. On the other hand, consuming animal proteins, heme iron, and having a high glycemic load were associated with significantly higher odds of endometriosis.ConclusionOur research supports the hypothesis that following a fertility diet may decrease the odds of endometriosis in Iranian women. However, these findings should be verified through extensive, prospective studies.

Abstract Background: Changing the dietary pattern may be an alternative treatment for bacterial vaginosis, the prevalent vaginal infection in women. Methods: One hundred and forty-three bacterial vaginosis-affected women diagnosed by Amsel criteria and 151 healthy controls aged 18 to 45 entered the current case-control research. To calculate the alternative healthy eating index and dietary acid load score, food consumption was recorded with an accurate and precise food frequency questionnaire. The dietary acid load was measured by potential renal acid load (PRAL) and net endogenous acid production (NEAP) indices. Using logistic regression models, the association between the alternative healthy eating index and dietary acid load score with bacterial vaginosis was investigated. Results: The last tertile of the alternative healthy eating index had a 75% decreased odds of experiencing bacterial vaginosis in the adjusted model (adjusted odds ratio (aOR) = 0.25, 95% confidence interval (CI) = 0.12–0.53, P for trend = 0.001). Besides, vegetables (aOR = 0.34, 95% CI = 0.17–0.69, P for trend = 0.003), nuts and legumes (aOR = 0.44, 95% CI = 0.23–0.87, P for trend = 0.028), and meats (aOR = 0.31, 95% CI = 0.16–0.60, P for trend = 0.001) intake was linked to a decreased bacterial vaginosis odds. However, sugar-sweetened beverages and fruit juice (aOR = 3.47, 95% CI = 1.68–7.17, P for trend

Abstract Bacterial vaginosis (BV) is a predominant vaginal disturbance that affects about 25% of childbearing-aged women. Dietary consumption may have a crucial role in vaginal flora imbalances. This study was a hospital-based case–control study. In total, 144 incident BV cases and 151 healthy participants were recruited from the gynecology clinic in Tehran, Iran, between November 2020 and June 2021. Participants' typical diets were collected by a food frequency questionnaire. Vaginal flora was characterized based on the Amsel criteria. Factor analysis was used to pinpoint the principal dietary patterns. For logistic regression, the first tertile was assumed as a reference. Five principal dietary patterns emerged and were nominated as "Healthy diet," "Unhealthy diet," "Ovo-vegetarian diet," "Pseudo-Mediterranean diet," and "Western diet." The "Unhealthy diet" pattern were positively associated with BV (adjusted odds ratio (aOR) = 3.35; 95% confidence interval (CI) 1.41, 7.94; ptrend: 0.006), while adherence to the "Ovo-vegetarian diet" pattern was associated with a reduced odds of BV (aOR = 0.16; 95% CI 0.07, 0.34; ptrend

Abstract Background Bacterial vaginosis, BV, is a common inflammatory vaginal dysbiosis. The Mediterranean diet, MD, containing foods rich in antioxidant compounds, is shown to be beneficial for inflammatory conditions. This study aimed to investigate the association between MD adherence and dietary total antioxidant capacity (DTAC) with BV. Methods This case–control study was conducted on 143 BV-affected and 151 healthy individuals aged between 15 and 45 years. The Amsel criteria were used to detect newly diagnosed patients with BV by a gynecologist. The 168-item food frequency questionnaire (FFQ) was used to record participants' dietary intakes in the last year. The reported data in the FFQ was used to measure adherence to the MD by calculating the Medi-Lite score and to measure the DTAC by calculating ferric-reducing antioxidant power, FRAP, based on the related databases. Logistic regression models were used to determine the association between Medi-Lite and DTAC and BV odds. Results The highest tertile of Medi-Lite score was associated with a reduced odds of BV in the crude model (Odds Ratio, OR: 0.49, 95% Confidence Interval, 95% CI 0.25, 0.96, P for trend: 0.023). This significant inverse association was not observed in the last model adjusted for age, body mass index (kg/m2), waist circumferences (cm), cigarette smoking, frequency of pregnancy, and physical activity (MET/h/d). In crude and adjusted odels, BV odds decreased in the highest tertile of vegetable (adjusted OR, aOR: 0.32, 95% CI 0.16, 0.63, P for trend: 0.001), fish (aOR: 0.46, 95% CI 0.25, 0.84, P for trend: 0.009), legumes (aOR: 0.26, 95% CI 0.14, 0.50, P for trend

Introduction: Endometriosis is a multifactorial disease. Limited studies have been published on the relationship between nutritional factors and endometriosis. This study was performed with aim to determine the association between dietary intake and anthropometric indices with endometriosis.Methods: This case-control study was performed in 2020-2021 on 317 women aged 18 to 49 years in Tehran. Endometriosis was diagnosed using laparoscopy and women were divided into case (n=107) and control (n=210) groups. Food intake was assessed using a semi-quantitative and reliable food frequency questionnaire including 168 food items and analyzed with N4 nutrition software. Data were analyzed using SPSS software (version 22) and logistic regression test. P

Introduction: Some of the etiological factors of hyperemesis gravidarum are increased fatty acid peroxidation and deficiency of vitamins and antioxidants. This study was performed with aim to determine the relationship between pre-pregnancy food group intakes and severe hyperemesis gravidarum.Methods: This case-control study was performed in 2020-2021 on 171 pregnant women aged 18-35 years referred to the hospitals of Tehran. Hyperemesis gravidarum was diagnosed using the American College of Obstetrics and Gynecology criteria, and participants were divided into the case and control groups. A semi-quantitative valid and reliable food frequency questionnaire containing 168 food items was used to assess food intake of participants in the past year before pregnancy. Data analysis was performed by SPSS statistical software (version 22), using Chi-square, Mann-Whitney and logistic regression tests. A p-value lower than 0.05 was considered statistically significantResults: The case group had significantly higher total fat and saturated fat intakes compared with controls. Median intakes of vitamin B groups, vitamin A and vitamin C were significantly higher among controls than cases. After adjusting for confounding variables, participants in the upper tertile of intakes of vegetables (OR=0.39, CI: 0.19-0.43) and fruits (OR=0.51, CI: 0.31-0.83) had a lower possibility of hyperemesis gravidarum. However, participants in the upper tertile of intakes of processed meats (OR=3.93, CI: 1.04-6.11) and organ meats (OR=2.39, CI: 1.23-5.03) were significantly more likely to be suffering from hyperemesis gravidarum.Conclusion: There was a significant inverse association between intake of vegetables, fruits, fish and seafood, whole grains, legumes, nuts, olives and olive oil with hyperemesis gravidarum. However, intake of high-fat dairy products, processed meats, organ meats, sweets, solid fats had a significant direct association with hyperemesis gravidarum.

Introduction: Bacterial vaginosis is the most common vaginal infection in women of childbearing age. Identifying nutritional risk factors as a potential therapeutic target can be important. This study was performed with aim to determine the relationship between the consumption of ultra-processed foods and bacterial vaginosis. Methods: This case-control study was performed in 2020 on 144 women with bacterial vaginosis and 151 healthy women aged 15-45 years referred to the gynecology clinic of Imam Hossein Hospital in Tehran. Bacterial vaginosis was diagnosed using the Amsel criteria and participants were divided into case and control groups based on it. Food intake of participants during 1 last year was collected using a valid semi-quantitative food frequency questionnaire with 168 food items. Ultra-processed foods were classified according to the NOVA classification system. A logistic regression test was used to investigate the association between the consumption of ultra-processed foods with bacterial vaginosis, and then the odds ratio was calculated. P< 0.05 was considered significant. Results: After adjusting for confounding variables, it was seen that participants in the upper tertile of intakes of the ultra-processed foods (OR=2.13, CI: 1.19-3.8, P=0.004), processed meats and fast foods (OR=2.27, CI: 1.23-4.2, P=0.008), oils and sauces (OR=2.47, CI: 1.34-4.54, P=0.004) and sweets (OR=2.82, CI: 1.5-5.3 P=0.001) were significantly more likely to be suffering from bacterial vaginosis than the group in first tertile. Conclusion: There was a direct relationship between the intake of ultra-processed foods, processed meats and fast foods, oils and sauces and sweets with bacterial vaginosis.

IntroductionAcute kidney injury (AKI) has been associated with an increased mortality rate among hospitalized patients with Coronavirus disease 2019 (COVID-19). The current review aimed to evaluate the symptoms, complications, and treatments performed to manage AKI in patients with COVID-19.MethodsWe searched PubMed/Medline, Web of Science, and Embase for the relevant scientific literature published up to February 1, 2022. The following keywords were used: “COVID-19”, “SARS-CoV-2”, and “Acute kidney injury”.ResultsForty-four studies with a total number of 114 COVID-19 patients with AKI (Mean age: 53.6 years) were included in our systematic review. The most common comorbidities in patients with COVID-19 suffering from AKI were the history of diabetes, hypertension, and hyperlipidemia. Twelve out of the 44 included studies reported a history of chronic kidney disease (CKD) in this group of patients. Focal segmental glomerulosclerosis (FSGS) and acute tubular necrosis (ATN) were the most common pathological evidence. The average length of hospital stay was 19 days, and the average duration of need for mechanical ventilation was 3 days.ConclusionsThe current systematic review shows that AKI frequently complicates the course of COVID-19 hospitalizations and is associated with increased severity of illness, prolonged duration of hospitalization, and poor prognosis. Given the extent of the adverse impact of AKI, early detection of comorbidities and renal complications is essential to improve the outcomes of COVID-19 patients.

Background. Inconsistent findings have been reported for associations between dietary indices and bacterial vaginosis (BV). The aim of this study was to examine the association of dietary glycemic index (DGI), glycemic load (DGL), insulin index (DII), and insulin load (DIL) with BV among Iranian women. Methods. The current case-control study consisted of 144 new cases of BV and 151 controls. The diagnosis of BV was made based on the Amsel criterion in hospital clinics in Tehran, Iran, from November 2020 until June 2021. DGI, DGL, DII, and DIL were calculated from a validated semiquantitative food frequency questionnaire. The association between dietary carbohydrate indices and odds of BV were assessed adjusting for potential confounders through an estimation of two multivariate regression models. Results. The multivariate adjusted odds ratio (OR) comparing the highest tertile of dietary DGI and DGL with the lower tertile was 2.99 (95% confidence interval (CI): 1.47–6.81; Ptrend=0.003) and 4.01 (95% CI: 1.22–5.91; Ptrend=0.029), respectively. In a fully adjusted model, the top tertile of dietary fiber compared to the bottom was associated with 88% (95% CI: 0.14-0.33) lower odds of BV (Ptrend

Background: Cardiomyopathies (CMPs) due to myocytes involvement are among the leading causes of sudden adolescent death and heart failure. During the COVID-19 pandemic, there are limited data available on cardiac complications in patients with COVID-19, leading to severe outcomes.Methods: We conducted a systematic search in Pubmed/Medline, Web of Science, and Embase databases up to August 2020, for all relevant studies about COVID-19 and CMPs.Results: A total of 29 articles with a total number of 1460 patients were included. Hypertension, diabetes, obesity, hyperlipidemia, and ischemic heart disease were the most reported comorbidities among patients with COVID-19 and cardiomyopathy. In the laboratory findings, 21.47% of patients had increased levels of troponin. Raised D-dimer levels were also reported in all of the patients. Echocardiographic results revealed mild, moderate, and severe Left Ventricular (LV) dysfunction present in 17.13, 11.87, and 10% of patients, respectively.Conclusions: Cardiac injury and CMPs were common conditions in patients with COVID-19. Therefore, it is suggested that cardiac damage be considered in managing patients with COVID-19.

Introduction The association between Coronavirus Disease 2019 (COVID-19) and abortion has been debated since the beginning of the COVID-19 pandemic. We aimed to conduct this systematic review to understand better the potential effects of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) on fetal loss in infected mothers presented with abortion following this infection. Methods We included articles published in PubMed/Medline, Web of Science, clinicaltrials.gov, and Embase databases in 2019 and 2020 through a comprehensive search via appropriate keywords, including COVID-19 and abortion synonyms. All studies with the abortion data in COVID-19 confirmed pregnant females were collected. Results Out of 208 potentially relevant articles, 11 articles were eligible to include in the systematic review. The included reports were published because of the following reasons: (1) First-trimester miscarriage; (2) Late miscarriage; (3) complication of COVID-19 infection in pregnancy; (4) COVID-19 disease in artificial pregnancy. First-trimester abortion was found in 5 studies, and second-trimester abortion in 7 studies. Two patients acquired infection during the hospital stay while they were referred for abortion. Reports related to abortion in pregnant females with COVID-19 show that most miscarriages due to COVID-19 in the first trimester were due to placental insufficiency. Conclusions There is an increased risk of abortion in mothers with a positive test result of SARS-CoV-2, which several case reports and case series have identified during the pandemic. Placental inflammation during the viral infection may result in fetal growth retardation and induce abortion. There has not been any consistent evidence of vertical transmission of the virus from mother to fetus, which requires further investigation.
