Objectives To determine the risk of having OSA in a cohort of female subjects who are infertile and the odds of being infertile in women with OSA. Patients and methods A nationwide, case-control study of female patients 20 years or older diagnosed with female infertility living in Taiwan, from January 1, 2000, through December 31, 2013 (N = 4,078). We identified women who were infertile and created a 2:1 matched control group with women who were not infertile. We used multivariable logistic regression analysis to further estimate the effects of OSA on female infertility. Results In this 14- year retrospective study, we included 4,078 patients having an initial diagnosis of female infertility. Of those women with infertility, 1.38% had a history of OSA compared with 0.63% of fertile controls (p = 0.002). The mean ages in the study groups were 32.19 ± 6.20 years, whereas the mean ages in the control groups were 32.24 ± 6.37years. Women with OSA had 2.101- times the risk of female infertility compared to women without OSA (p<0.001). Conclusion Our study showed that OSA is more commonly seen in infertile women and increases the odds that a woman will be infertile. More studies need to be done on the whether or not diagnosing and treating OSA can decrease the rate of infertility.

A case-control study conducted in the Department of Dermatology and Venereology of Bangabandhu Sheikh Mujib Medical University, Dhaka from July 2008- December 2010. A total 60 female patients of telogen effluvium attending in outpatient department (OPD) were enrolled in the study with 30 having hair loss considered as case (Group-A) and another 30 females had no history of hair loss were considered as control (Group-B). The study included 60 patients and the mean age were 25.4±7 years ranging from 18 to 42 years in group A and 24.8±5.6 years ranging from 17 to 36 years in group B. Maximum number was found in the age group of 21- 30 years in both groups and nearly three fourth (73.4%) patients were unmarried in group A and 18(60.0%) in group B. Most of the patients were student in both groups, which were 21(70.0%) and 17(56.7%) in group A and group B respectively and majority of the the patients were HSC level in both groups, 15(50.0%) and 14(46.7%) in Group A and Group B respectively. Most of the patients came from middle class, which were 20(66.7%) and 16(53.3%) in group A and group B respectively. The mean serum ferritin were 18.8±8.1 g/L ranging from 4.5 to 36.54 g/L and 36.6±9.9 mg/L ranging from 18.46 to 56.3 mg/ L in group A and group B respectively. The mean Hb level was 11.5±1.4 gm/dl ranging from 8.5 to 14.0 gm/dl in group A and 12.8±1.1 gm/dl ranging from 10.5 to 14.5 gm/dl in group B. The mean difference of Hb level was statistically significant (p<0.05) between two groups in unpaired t-test. It can be concluded that low iron level is associated with telogen effluvium in women.

ABSTRACT:To determine whether a history of exposure to rural environmental factors leads to an increased likelihood of developing idiopathic Parkinson's disease, we conducted a case-control study of 130 cases and 260 randomly selected community controls (matched with the cases by sex and age ± 2.5 years at a ratio of 2 controls: 1 case) in the city of Calgary. The data were collected by personal interviews and were analyzed using conditional logistic regression for matched sets. The ages of the cases ranged from 36.5 to 90.7 years (mean = 68.5 ± 11.3 years). The mean age at diagnosis was 61.1 ± 12.4 years. The mean duration of disease was 7.8 ± 0.6 years. Eleven (9.1%) cases were diagnosed before age 40. In this sample from the Province of Alberta, Canada, no significant increase in risk for Parkinson's disease was associated with a history of rural living, farm living, or well water drinking in early childhood or at any time during the first 45 years of life.

Abstract Introduction The ICSD-3 describes NREM-related parasomnias as abnormal sleep related complex movements where motor behavior occurs in the setting of absent or very minimal higher cognitive function. A population-based twin study reported that 3.9% of men and 3.1 % of women sleepwalk (SW) with 30% reported experiencing injury (Hublin 1997). Sleep related eating disorder (SRED) may be a variant of SW with a reported prevalence of 0.5-5 % (Michalska 2016). This study examined SW and SRED in a population-based sample permitting review of associated features, risk factors and outcomes. Methods The records-linkage system of the Rochester Epidemiology Project that includes all adults residing in Olmsted County MN was searched for documentation of patients seeking care for at least two episodes of sleepwalking and/or sleep eating. Records from 2007-2016 were included. Results 56 cases were identified with 50 (89 %) having SW and 16 (29%) SRED. The gender breakdown was 50% male and 50% female with the mean age at diagnosis of 40 (SD 13). Childhood parasomnia events were reported by 23/36 (62%) and a family history in 21/35 (64%). Data were unavailable for the others. The number of parasomnia incidents was ≥ 10 for 21 (37%). A variety of experiences were documented, including leaving the bedroom (39%), injury (25%), and exiting through a window/balcony (5%). Associated factors were sleep deprivation (52%), untreated obstructive sleep apnea (34%), antidepressant use (41%), zolpidem use (18%), circadian disruption (14%) and alcohol use (9%). Polysomnography was conducted for 41 (74%). Documented interventions were medication discontinuation (18%) and starting a benzodiazepine (16%). In 21%, no treatment was given. Conclusion This population-based study of adults with clinician diagnosed recurrent SW and SRED revealed equal rates in men and women. The majority of patients with SRED also had SW. 25% of cases were associated with injuries. Support Rochester Epidemiology Project supported by NIH R01 AG034676 and AG052425 and the Mayo Foundation.

Background: Bullous pemphigoid (BP) and asthma both share a pathogenic role of eosinophils and immunoglobulin E (IgE) and favorable response for corticosteroids and omalizumab. However, the association between these conditions is yet to be investigated. We sought to estimate the risk of having BP among patients previously diagnosed with asthma and to characterize patients with coexistent BP and asthma. Methods: Utilizing the dataset of Clalit Health Services, a population-based case-control study was conducted comparing BP patients (n = 3,924) with age-, sex-, and ethnicity-matched control subjects (n = 19,280) regarding the presence of asthma. Logistic regression models were utilized for univariate and multivariate analyses. Results: The prevalence of preceding asthma was higher in patients with BP than in control subjects (11.1 vs. 7.9%, respectively; p < 0.001). A history of asthma was associated with a 50% increase in the risk of BP (OR 1.45; 95% CI 1.30–1.62). The association was not altered greatly after adjusting for demographics (adjusted OR 1.43; 95% CI 1.28–1.61) as well as for demographics and comorbidities (adjusted OR 1.40; 95% CI 1.25–1.57). The average (SD) latency between the diagnosis of asthma and the development of BP was 12.5 (14.7) years. When compared with other patients with BP, those with a dual diagnosis of BP and asthma were older, had higher BMI, and were more frequently managed by corticosteroids and immunosuppressive and immunomodulatory adjuvants. Conclusions: Asthma confers a predisposition to the development of BP. Awareness of this association may be of help for physicians managing patients with BP and asthma. Further research is required to elucidate the mechanism underlying this observation.

The purpose of this study was to investigate the personality characteristics in adolescents with SLE. The research design is a case-control study by means of the Rorschach Method and the Wechsler Intelligence Scale. Study group: 30 female adolescents with lupus, 12–17 years of age. The SLE Disease Activity Index was administered during the period of psychological evaluation. Control group: 32 nonpatient adolescents were matched for age, sex, and socioeconomic level. In the Wechsler Intelligence Scale the mean IQ of the experimental group was significantly lower than that of the control group (77 and 98, respectively, p < .001). In the Rorschach, the lupus patients showed greater difficulty in interpersonal interactions, although they displayed the resources to process affect and to cope with stressful situations. A positive moderate correlation (p = .069) between the activity index of the disease and the affect constriction proportion of the Rorschach was observed: the higher the SLEDAI score, the lower the capacity to process affect. There is a negative correlation between the activity index of the disease and the IQ (p = .001): with a higher activity index of the disease, less intellectual resources are available.

Background:Systemic sclerosis is a disorder of connective tissue with unknown cause, affecting the skin and internal organs, characterized by fibrotic changes.Objective:To determine the correlation between serum homocysteine level and interstitial lung involvement in systemic sclerosis. </P><P> Materials and Methods: In this case – control study, 59 patients who fulfilled the ACR/EULAR classification criteria for systemic sclerosis and were referred to Hafez Hospital of Shiraz, Iran, were included as the case group. Fifty nine healthy subjects were involved as the control group. Patients were divided into two groups based on interstitial lung involvement and two subtypes, diffuse and limited type. Serum homocysteine, vitamin B12, and folate levels compared between the controls, and cases groups.Results:Of 59 case and control group, 53 (%89.8) were female and the mean age did not differ in both groups (P=0.929). Thirty five (%59.3) patients had interstitial lung involvement and 38(%64.4) had diffuse cutaneous systemic sclerosis. The mean serum homocysteine level was 13.9±6.3 µmol/L in the case and 13.7±9.2 µmol/L in the control group (P=0.86). The mean serum homocysteine level did not differ between the patients with and without interstitial lung involvement (P=0.52). The patients with lung involvement was older than those without lung involvement (P=0.004). Lung disease was more common in diffuse type (P=0.014).Conclusion:In our study, serum homocysteine level did not differ between the patients and healthy subjects. Also, there was no correlation between serum homocysteine level and lung involvement, but lung involvement was more common in older patients and also diffuse subtype.

Accumulating evidence has shown a significant correlation between periodontal diseases and systemic diseases. In this study, we investigated the association between the frequency of tooth scaling and acute myocardial infarction (AMI). Here, a group of 7164 participants who underwent tooth scaling was compared with another group of 7164 participants without tooth scaling through propensity score matching to assess AMI risk by Cox’s proportional hazard regression. The results show that the hazard ratio of AMI from the tooth scaling group was 0.543 (0.441, 0.670) and the average expenses of AMI in the follow up period was USD 265.76, while the average expenses of AMI in follow up period for control group was USD 292.47. The tooth scaling group was further divided into two subgroups, namely A and B, to check the influence of tooth scaling frequency on AMI risk. We observed that (1) the incidence rate of AMI in the group without any tooth scaling was 3.5%, which is significantly higher than the incidence of 1.9% in the group with tooth scaling; (2) the tooth scaling group had lower total medical expenditures than those of the other group because of the high medical expenditure associated with AMI; and (3) participants who underwent tooth scaling had a lower AMI risk than those who never underwent tooth scaling had. Therefore, the results of this study demonstrate the importance of preventive medicine.

AbstractNeurofibromatosis 1 (NF1) is an inherited, autosomal-dominant, tumor predisposition syndrome with a birth incidence as high as 1:2000. A patient with NF1 is four to five times more likely to develop a malignancy as compared to the general population. The number of epidemiologic studies on lymphoproliferative malignancies in patients with NF1 is limited. The aim of this study was to determine the incidence rate of lymphoproliferative malignancies (lymphoma and leukemia) in NF1 patients followed in our referral center for neurofibromatoses. We used the Informatics for Integrated Biology and the Bedside (i2b2) platform to extract information from the hospital’s electronic health records. We performed a keyword search on clinical notes generated between Jan/01/2014 and May/11/2020 for patients aged 18 years or older. A total of 1507 patients with confirmed NF1 patients aged 18 years and above were identified (mean age 39.2 years; 57% women). The total number of person-years in follow-up was 57,736 (men, 24,327 years; women, 33,409 years). Mean length of follow-up was 38.3 years (median, 36 years). A total of 13 patients had a medical history of either lymphoma or leukemia, yielding an overall incidence rate of 22.5 per 100,000 (0.000225, 95% confidence interval (CI) 0.000223–0.000227). This incidence is similar to that of the general population in France (standardized incidence ratio 1.07, 95% CI 0.60–1.79). Four patients had a medical history leukemia and 9 patients had a medical history of lymphoma of which 7 had non-Hodgkin lymphoma, and 2 had Hodgkin lymphoma. Our results show that adults with NF1 do not have an increased tendency to develop lymphoproliferative malignancies, in contrast to the general increased risk of malignancy. While our results are consistent with the recent population-based study in Finland, they are in contrast with the larger population-based study in England whereby NF1 individuals were found to be 3 times more likely to develop both non-Hodgkin lymphoma and lymphocytic leukemia. Large-scale epidemiological studies based on nationwide data sets are thus needed to confirm our findings.

Abstract Aims Pulse pressure (PP) is a well-known risk factor for cardiovascular disease. However, the association between the PP and dementia is not well identified. This study aimed to determine the effect of PP on the risk of dementia development in different age subgroups using a longitudinal, population-based, and stroke-free cohort from the general population. Methods The association of PP with the development of incident dementia was assessed from January 1, 2005, to December 31, 2013, in 433,154 participants without a history of dementia or stroke from the Korea National Health Insurance Service-Health Screening cohort. The diagnosis of dementia was defined using the 10th revision of the International Classification of Disease codes. Results The mean age of the cohort was 55.7±9.2 years, 45.7% were women. Hypertension was 23.6%. The mean systolic and diastolic blood pressure of the entire cohort were 125.9±16.6 and 78.4±10.7 mmHg, respectively. Mean PP was 47.5±10.9 mmHg. In the middle-age group (40 to 50 year-old), increasing of 10 mmHg of PP was associated with incident dementia after adjusting mean blood pressure and clinical variables with a hazard ratio (HR) of 1.21 (95% confidence interval [CI]: 1.19–1.23, p&lt;0.001). The association was still significant even after censoring for stroke (HR: 1.16, 95% CI: 1.08–1.22, p&lt;0.001). In the older population, elevation of PP was not associated with dementia development (HR: 0.98, 95% CI: 0.95–1.01, p=0.247) Conclusion PP was associated with increased risk of dementia only in middle-aged population beyond that of mean arterial pressure.
