Long-term use of gastric-acid-suppressive drugs is known to be associated with several adverse effects. However, the association between enteric infection and acid suppression therapy is still uncertain. This study aimed to evaluate the association between gastric acid suppression and the risk of enteric infection. Materials and Methods: We conducted a population-based case-control study using the data from Chang Gung Research Database (CGRD) in Taiwan. Between January 2008 and December 2017, a total of 154,590 adult inpatients (age > 18) were identified. A pool of potential eligible controls according to four propensity scores matching by sex, age, and index year were extracted (n = 89,925). Subjects with missing data or who received less than 7 days of proton pump inhibitors (PPIs) and/or H2-receptor antagonists (H2RAs) were excluded. Finally, 17,186 cases and 69,708 corresponding controls were selected for analysis. The use of PPIs and H2RAs, the result of microbiological samples, and co-morbidity conditions have been analyzed. Confounders were controlled by conditional logistic regression. Results: 32.84% of patients in the case group used PPIs, compared with 7.48% in the control group. Of patients in the case group, 9.9% used H2RAs, compared with 6.9% in the control group. Of patients in the case group, 8.3% used a combination of PPIs and H2RAs, compared with 2.7% in the control group. The most common etiological pathogens were Enterococcus (44.8%), Clostridioides difficile (34.5%), and Salmonella spp. (10.2%). The adjusted odds ratio (OR) for PPI use with enteric infection was 5.526 (95% confidence interval [CI], 5.274–5.791). For H2RAs, the adjusted odds ratio was 1.339 (95% confidence interval [CI], 1.261–1.424). Compared to the control group, persons with enteric infection had more frequent acid-suppressive agent usage. Conclusions: This study demonstrates that gastric-acid-suppressive drug use is associated with an increased risk of enteric infection after adjusting for potential biases and confounders.

<b><i>Aim:</i></b> The aim of this study is to examine possible associations between the transfusion of RBC or platelets (PLTs) and the development of retinopathy of prematurity (ROP) in infants. <b><i>Methods:</i></b> This retrospective, national, case-control study included all live births in Switzerland between 2013 and 2018. We investigated preterm infants at a gestational age of &#x3c;28 weeks, who developed higher stage ROP (≥stage 2, <i>n</i> = 178). Each case infant was matched to another of the same sex who did not develop ROP (<i>n</i> = 178, control group). <b><i>Results:</i></b> When compared with the control group, we observed higher numbers of RBC transfusions per infant and higher percentages of infants receiving PLT transfusions in the case group. An adjusted logistic regression analysis revealed that both RBC (odds ratio [OR] 1.081, 95% confidence interval [CI] 1.020–1.146) and PLT transfusions (OR = 2.502, 95% CI 1.566–3.998) numbers were associated with ROP development. <b><i>Conclusions:</i></b> Multiple RBC and PLT transfusions are associated with higher stage ROP development. Prospective studies are required to determine their potential as risk factors.

Control Study

From March thru April 1990 an unmatched case-control study had been conducted at the pediatric out-patient Clinic of Dr. Pirngadi Hospital Medan to assess risk factors of infantile diarrhea. The  study population were infants, aged younger than 21 months. The mothers of the infants were interviewed, using structured questionnaires. Sample size, calculated by means of formula, with 95 % level of confidence, 90 % power of study, 50% estimated proportion of exposure in the control-group and 2.0 estimated odds ratio, was 121. All infants with diarrhea were included in the case-group until a total number of 124 infants were reached. One control, an infant without diarrhea, was taken for each case from the nearest sequence of attendance after the case. A total of 20 risk factors were tested. Exposure was indicated from the last day before illness. Computerized statistical analysis was performed to calculate odds ratio, 95 % confidence interval and two tailed significance testing for qualitative dichotomic data by means of Chi square test. A total of nine factors were confirmed as risk factors of infantile diarrhea i.e mothers age than 20 years, working mother, not cleaning nipple before suckling the baby bottle feeding, having only one nursing botlle/teat, not ready for use nursing bottle/teat, giving left over supplementary food without reheating, no band-washing before giving supplementary food and malnutrition. The result of this study can be emphasized in health education, especially in diarrheal disease control of infancy; Further well-designed studies are needed.

Purpose: On the basis that spironolactone is involved in ACE2 expression and TMPRSS2 activity, previous studies have suggested that spironolactone may influence the infectivity of COVID-19. Research has suggested that cell entry of SARS-CoV-2, the virus that induces COVID-19, is associated with the ACE2 receptor and TMPRSS2. The purpose of this study was to investigate whether spironolactone has a protective effect against COVID-19 and the development of associated complications in patients with liver cirrhosis.Methods: We conducted a nationwide case-control study on liver cirrhosis patients with or without COVID-19 from the population-based data acquired from the National Health Insurance Systems of Republic of Korea. After 1:5 case-control matching, multivariable adjusted conditional logistic regression analysis was performed.Results: Among the patients with liver cirrhosis, the case group with COVID-19 was found to be significantly less exposed to spironolactone compared with the control group without COVID-19. The adjusted odds ratio (OR) and 95% confidence interval (CI) between the two groups was 0.20 (0.07–0.54). In addition, regardless of cumulative dose of spironolactone, exposure to spironolactone was associated with lower COVID-19 infection. In terms of the development of complications due to COVID-19, spironolactone did not show any significant association between the patients with and without complications (P = 0.43). The adjusted OR and 95% CI between the two groups was 1.714 (0.246–11.938).Conclusion: We conclude that spironolactone may reduce susceptibility to COVID-19 but does not affect the development of its associated complications; however, further studies are needed to confirm the exact association between spironolactone and COVID-19 infection.

Abstract Polyunsaturated fatty acids (PUFAs) are critical for brain development and have been linked with neurodevelopmental outcomes. We conducted a population-based case-control study in California to examine the association between PUFAs measured in midpregnancy serum samples and autism spectrum disorder (ASD) in offspring. ASD cases (n = 499) were identified through the California Department of Developmental Services and matched to live-birth population controls (n = 502) on birth month, year (2010 or 2011), and sex. Logistic regression models were used to examine crude and adjusted associations. In secondary analyses, we examined ASD with and without co-occurring intellectual disability (ID; n = 67 and n = 432, respectively) and effect modification by sex and ethnicity. No clear patterns emerged, though there was a modest inverse association with the top quartile of linoleic acid level (highest quartile vs. lowest: adjusted odds ratio = 0.74, 95% confidence interval: 0.49, 1.11; P for trend = 0.10). Lower levels of total and ω-3 PUFAs were associated with ASD with ID (lowest decile of total PUFAs vs. deciles 4–7: adjusted odds ratio = 2.78, 95% confidence interval: 1.13, 6.82) but not ASD without ID. We did not observe evidence of effect modification by the factors examined. These findings do not suggest a strong association between midpregnancy PUFA levels and ASD. In further work, researchers should consider associations with ASD with ID and in other time windows.

Abstract Objective: Reproductive disorders are a global health problem with high prevalence in all parts of the World. Their etiology can be attributed to several factors such as psychological, social, economical and physical. The aim of this study was to investigate the relationship between major dietary patterns with fertility status in Iranian men in Yazd province.Methods: In this case-control study, 400 infertile men were recruited into study during their fertility investigation in Yazd Reproductive sciences Institute by diagnosis an andrologist as the case group. The control group consisted of 604 healthy men without infertility history that selected from Shahedieh cohort study, recruitment phase from 2015 to 2016 (during one year),Yazd, Iran, according to the inclusion criteria. Multivariate logistic regression was used to determine the relationship between dietary patterns and infertility. All data of the major dietary patterns were analyzed using SPSS V. 22 software.Results: five dietary patterns were extracted. These dietary patterns were grouped as Western, Healthy, Traditional, Fat-based and Mixed. After adjusting for age and level of education, the third tertile of the mixed Dietary Pattern had the highest odds ratio (OR = 7.2; 95% CI, 4.4-11.7) for infertility. In Model 2, the second tertile of the traditional dietary pattern had the lowest Odds ratio (OR = 0.012;95%CI, 0.006-0.023) About infertility. In model 3, Third tertile of western (OR = 6.3; 95% CI, 3.3-12.1) and mix dietary patterns (OR = 2.9; 95% CI, 1.6-5.2) had the highest odds ratio for infertility. The first tertile of each dietary pattern was considered as the reference level.Conclusions: We concluded in this study that adherence to the Western dietary pattern in model 3, Mix and fat-based pattern in model 2 was associated with high risk for infertility. On the other hand, adherence to the traditional and healthy dietary pattern had a protective effect on male infertility. Further studies are needed to confirm the findings of this study.

Abstract Background In March 2020, the US Food and Drug Administration decided that the dangers related to neuropsychiatric events (NPEs) of montelukast, one of the leukotriene modifying agents (LTMAs), should be communicated through ‘boxed warning’. In case of NPEs, the prevalence has been the highest in elderly people. Because the characteristics of the elderly such as old age itself can act as risk factors. Therefore, an investigation on safety of LTMAs related to NPEs in elderly using LTMAs is needed. Method A nested case-control study using an elderly sample cohort from the Korean National Health Insurance Service database was used. The asthma cohort included asthma patients newly diagnosed between 2003 and 2013. Within the asthma cohort, the case group was defined as patients who were diagnosed with NPEs. Among patients who had never been diagnosed with NPEs, the control group was selected by matching 1:1 by propensity score. Patients who were prescribed LTMAs for 1 year prior to index date were defined as the exposure group. The logistic regression model was used to measure the effect of LTMAs on NPEs. Results We identified 141,165 patients with newly diagnosed asthma, and selected 31,992 patients per each case and control group. Exposure to LTMAs significantly increased the risk of overall NPEs about in comparison with the absence of exposure (crude odds ratio [OR] 1.58, 95% CI 1.50–1.68). After adjusting for confounding factors, the overall NPEs risk increased (adjusted OR, 1.67, 95% CI 1.58–1.78). Conclusion This study suggests that elderly asthma patients prescribed LTMAs had a higher risk of NPEs than patients who were not treated with LTMAs. Therefore, clinicians should be aware of the potential risks of LTMAs.

Abstract Background Coronary hearth diseases are among the main causes of death in adults. Increase of oxidative stress and defects in antioxidant defense play a major role in endothelium performance and are an effective factor in progress of atherosclerosis. Some studies have also reported different malondialdehyde and total antioxidant capacity among the atherosclerosis patients.Methods In this case-control study, 44 atherosclerosis patients referring to Shahid Madani treatment-education center were considered as the case group; while 44 healthy peoples were placed in the control group. Demographic data and anthropometric indices were measured. Food frequency questionnaire and international physical activity questionnaires were also completed. After 12 hours of fasting, 10 ml blood was sampled from the participants. Uric acid, vitamin C, TAC and MDA were also measured. The data were finally analyzed by SPSS Ver 22 software.Results A significant difference was observed between the two groups in terms of uric acid (P<0.001) and vitamin C (P<0.03). However, mean MDA and TAC showed no significant difference between the two groups. The two groups’ difference in terms of vitamin A, E and beta carotene, zinc and selenium intake was not significant. A significant difference was however detected between the two groups in terms of vitamin C (P<0.047). A significant relationship was also observed between the systolic pressure and CHD (P<0.028).Conclusion Results of this study indicated that the uric acid and vitamin C levels of atherosclerosis patients had significant increase and decrease in comparison with the healthy subjects, respectively. Mean TAC and antioxidant levels of their diets (except for vitamin C) showed no significant difference. Systolic blood pressure of the patients was significantly higher than the controls.

Abstract Background The association between anxiety and atrial fibrillation (AF) remains unclear. Moreover, this association has rarely been studied in Chinese individuals aged 60 years or older. This study investigated the association between anxiety and AF in a community-based case-control study of older adult residents in urban China. Methods The cases and controls were from a community-based study conducted in the Jingansi community in Shanghai, China, between January 2010 and December 2012. A total of 3622 residents aged 60 years or older without severe vision, hearing, or speaking impairments were eligible to participate in the physical examinations and questionnaire survey. AF was assessed based on a previous physician’s diagnosis, electrocardiogram, ambulatory electrocardiogram, or echocardiogram. Anxiety was evaluated using the Zung Self-Rating Anxiety Scale (ZSAS). Using the AF group as a reference, the control group consisted of randomly selected age- and sex-matched individuals in a 1:5 ratio (case:control = 1:5). The association between anxiety and AF in the AF group and the multifactor-matched control group was explored using logistic regression. Results In the AF and control groups, after adjusting for a history of coronary heart disease, valvular heart disease, hypertension, stroke, hyperlipidemia, and diabetes, as well as depression score, ZSAS scores (odds ratio 1.07; 95% confidence interval 1.02–1.12; p = 0.003), and anxiety symptoms (odds ratio 3.94; 95% confidence interval 1.06–14.70; p = 0.041) were associated with AF. Conclusions Anxiety symptoms were associated with AF in a Chinese older population. This suggests that older adults who have anxiety symptoms may need psychological intervention or treatment in daily life and care.

Background: Polycystic Ovarian Syndrome (PCOS) is one of the most common causes of infertility in women. Objective: The current study investigated mental and personality disorders in infertile women with and without PCOS. Methods: This case-control study evaluated 400 infertile women who referred to the Infertility Center in Babol city (North of Iran). Participants were categorized into the case group (201 PCOS) and the control group (199 without PCOS). All of the participants completed the Millon Clinical Multi-axial Inventory-III (MCMI-III). Results: The mean scores for clinical personality patterns were significantly higher for six personality disorders (schiz- oid, avoidant, antisocial, depressive, sadistic, and negativistic) and for three classes of severe personality disorder patterns (schizotypal, borderline, and paranoid) in infertile women with PCOS than in women without PCOS. The mean scores for eight clinical disorders (somatoform, manic disorder, dysthymia, alcohol-dependence, drug-dependence, post-trauma stress disorder, major depression, and delusion disorder) were also higher in infertile women with PCOS than in women without PCOS. Conclusion: The scores of many mental and personality disorders are higher in infertile women with PCOS than in women without PCOS. Thus, clinicians should prioritize recognizing and treating psychological problems of infertile women with PCOS. Keywords: Polycystic ovarian syndrome; infertility; personality disorders.
