Background: Hypertensive disorders of pregnancy are a major cause of both maternal and foetal morbidity and mortality. Although pregnancy induced hypertension (PIH) is still regarded as a disease of theories and unknown etiology, elevated homocysteine level has been hypothesized as a key risk factor. Abnormally raised homocysteine has been significantly associated with increased risk of PIH, abruption, intrauterine growth restriction, recurrent pregnancy loss, intrauterine death and prematurity.Methods: The present case control study was conducted among 180 pregnant women (90 cases and 90 controls) in Kamla Nehru State Hospital for Mother and Child, IGMC Shimla, Himachal Pradesh with an objective of ascertaining the role of homocysteine in pregnancy related hypertensive disorders. Socio-demographic, clinical, biochemical including homocysteine level, laboratory and ultrasonographic parameters of all the participants were documented.Results: The mean homocysteine level of cases (18.30±10.81) was significantly higher than the controls (8.70±2.64).  About 62.2% cases had abnormally raised homocysteine level (>15 µmol/L), while only 1.1% controls had such level. The odds of a case having abnormally elevated homocysteine level were 146.6 (CI: 19.52-1101) times to that of controls. Eclamptics had the highest homocysteine level followed by preeclamptics and controls.Conclusions: The present study significantly associates the abnormally elevated homocysteine levels with pregnancy related hypertensive ailments and demands much needed robustly designed studies to further explore the phenomenon. A simple intervention like estimating the much neglected homocysteine levels prior to pregnancy can definitely aid in predicting and preventing perinatal outcomes.

Introduction Basal plate myometrium (BPMYO), the pathological presence of myometrial fibers in the basal plate, is a common finding on pathological examination of the placenta, yet its clinical correlates are not well studied. As myometrial fibers are frequently located in proximity to poorly converted maternal spiral arteries, our objective was to determine whether BPMYO is associated with hypertensive disorders of pregnancy (HDP), a well-known clinical sequela of abnormal maternal artery remodeling. Methods This case–control study included women who delivered a live-born singleton gestation whose placentas were sent for pathological examination. Cases were women with HDP (gestational hypertension, preeclampsia, or HELLP syndrome) as defined by American College of Obstetricians and Gynecologists. Controls were women without HDP. Women with chronic hypertension were excluded. The primary outcome was the presence of BPMYO. Secondary outcomes included the pathologic stage of BPMYO and the incidence of pathologically defined accreta. Each outcome was compared between cases and controls in bivariable and multivariable analyses. Results Of the 306 women who met inclusion criteria, 230 (75%) had HDP. BPMYO was present in 99 (32%) of placentas. Compared to controls, cases were younger, had higher body mass index, and were more likely to have diabetes, be nulliparous, deliver preterm, and have had a prior cesarean. There were no differences in the incidence of BPMYO, stage of BPMYO, or incidence of pathologically defined accreta between cases and controls. These findings persisted after controlling for potential confounders. Conclusions Although BPMYO may be more common in the setting of abnormal placental vasculature, there is no significant association between BPMYO and HDP.

Abstract Occupational exposures were investigated in a multicenter case-control study of clinically and histologically diagnosed idiopathic pulmonary fibrosis (IPF), a chronic diffuse interstitial lung disease of unknown etiology. Results are based on 248 cases, aged 20–75 years, diagnosed at 16 referral centers between January 1989 and July 1993. There were 491 controls ascertained by random digit dialing and matched to cases on sex, age, and geographic region. Data were collected using a standard telephone questionnaire. Occupational factors were based on a detailed history of jobs lasting 6 months or more and job activity, hobby, and specific substance checklists. Several occupational factors, adjusted for age and smoking in conditional multivariate logistic regression analyses, were significantly associated with IPF: farming (odds ratio (OR) = 1.6, 95% confidence interval (CI): 1.0, 2.5); livestock (OR = 2.7, 95% CI: 1.3, 5.5); hairdressing (OR = 4.4, 95% CI: 1.2, 16.3); metal dust (OR = 2.0, 95% CI: 1.0, 4.0); raising birds (OR = 4.7, 95% CI: 1.6, 14.1); stone cutting/polishing (OR = 3.9, 95% CI: 1.2, 12.7); and vegetable dust/animal dust (OR = 4.7, 95% CI: 2.1, 10.4). Interaction was detected between smoking and exposure to livestock (p = 0.06) and farming (p = 0.08). Results confirm previous studies showing increased risk associated with dusty environments.

Abstract Background Hypertension is the most common medical problem encountered in pregnancy and is a leading cause of perinatal and maternal morbidity and mortality. However, its magnitude and risk factors yet not adequately assessed at the study area. Methods Facility-based retrospective unmatched case-control study was conducted to identify risk factors associated with Hypertensive disorders of pregnancy in Nekemte Referral Hospital just two years back from study period July 1, 2015, to June 30, 2017. Bivariate logistic regression was considered for inclusion in to the multivariate logistic regression. Finally, multi varaite analysis were done to identify risk factors of hypertensive disorders of pregnancy. Results Among 6826 total delivery records from July 2015 –June 2017, 199 women developed hypertension during pregnancy. Among 199 women 153(76.9%) were pre-eclampsia/eclampsia,28(14.1%) were gestational hypertension, 14(0.7%) were superimposed hypertension and 4 (2.9%) were chronic hypertension. Age ≥ 35 (AOR: 2.51, 95% CI: 1.08, 5.83), rural residential area (AOR: 1.79, 95% CI: 1.150, 2.799), prim gravida (AOR: 3.39, 95% CI: 2.16, 5.33), null parity (AOR: 4.35, 95% CI: 2.36, 8.03), positive history of abortion (AOR: 4.39, 95% CI: 1.64, 11.76), twin pregnancy (AOR: 3.78, 95% CI: 1.52, 9.39), lack of ANC follow up (AOR: 3.05, 95% CI: 1.56, 5.96) as well as positive pre-existing hypertension (AOR: 3.81, 95% CI: 1.69, 8.58), positive family history of hypertension (AOR: 5.04, 95% CI: 2.66, 9.56) and positive history of diabetes mellitus (AOR: 5.03, 95% CI: 1.59, 15.89) were risk factors for hypertensive disorders during pregnancy. Conclusion This study found that Women with hypertension during pregnancy have a greater risk of developing adverse pregnancy outcome as compared to normotensive pregnant women. so, identification of these risk factors would be useful for early diagnosis of hypertension disorders during pregnancy to give appropriate clinical monitoring and treatments and timely managing maternal and perinatal complications.

IntroductionSarcoidosis is an inflammatory disease with unknown etiology that involves the formation of granulomas, mainly in the lungs and/or intrathoracic lymph nodes. Hypothesis about the etiology of sarcoidosis are combination of genetic and environmental factors. Previous studies have linked exposure to silica dust with increased risk of sarcoidosis.ObjectA case-control study to investigate the silica exposure among Swedish sarcoidosis cases.MethodsThe data was collected from the National non-primary outpatient care register kept by the Swedish National Board of Health and Welfare. All cases between the age of 20 and 65 with the diagnosis Sarkoidos-D86 according to the International Classification of Diseases, 10th Edition (ICD-10) was included in the study (11 772 cases). The information was matched towards the register for cause of death and the register for emigration.For each case two controls were included matched for age, sex, was resident in the same county, should not be first degree relatives to cases and not have been diagnosed with the investigated disease using the Swedish Central Bureau of Statistics (SCB) multigeneration register. Cases and controls was matched against SCBs occupational registry for work profession. The levels of silica dust exposure were estimated using NOCCA-JEM (Nordic Occupational Cancer study job-exposure matrix) a modified version of the Finnish Information System on Occupational Exposure job-exposure matrix (FINJEM) which is a well-established method of estimating exposure.ResultCases of sarcoidosis have an increased exposure to silica before diagnosis (1.19; 95%  CI 1.1 to 1.30).ConclusionThe increased exposure to silica among sarcoidosis cases suggest that silica can be an environmental factor that contribute to development of sarcoidosis.

Abstract BackgroundThe incidence of pregnancy syphilis remains at a high level in China. Studies investigating the influencing factors of pregnancy syphilis are mainly concentrated in economically developed areas. Limited studies were conducted in northern China. This study mainly aimed to explore the related factors of pregnancy syphilis and examine the association with the risk of Hypertensive disorders of pregnancy.MethodsThis case-control study compared pregnancy syphilis cases, matched (1:1) to non-syphilitic pregnant women controls by age, which was diagnosed in Changchun between January 2014 and December 2018. Multivariable logistic regression was used to identify potential correlates of HDP in syphilis populations. Then a propensity score-matched method was conducted to match pregnancy syphilis with and without HDP, and further we explore the related factors of HDP in syphilis by multivariable logistic regression.ResultsIn our study, the median age of syphilis in the case group was 28 years (range 16-53 years). A high rate of syphilis-HDP co-infection（49/349, 12.3%）was observed in syphilis patients and further research revealed an association between syphilis and HDP. Multivariate analysis indicated HDP in syphilis was independently associated with Dysmenorrhea [adjusted odds ratio (a OR) 5.413, 95% confidence interval (CI) 2.410-12.158], Maternal anemia (a OR 3.808, 95% CI 1.833-7.911), Total cholesterol (a OR 3.144, 95% CI 1.485-6.655).ConclusionSyphilis infection in pregnancy associate with the increased risk of hypertensive disorders of pregnancy, attention should also be paid to the occurrence of HDP in the lower age group, to further prevent the occurrence of stroke, cardiovascular disease. Besides, Dysmenorrhea, Maternal anemia, Total cholesterol may be risk factors for HDP in syphilis.
