<p><strong>OBJECTIVE:</strong> To compare oocyte yield of women with intact ovarian endometrioma(s) to those without endometrioma undergoing ART. Secondary outcomes were implantation and live birth rates between the two groups.</p><p><strong>STUDY DESIGN: </strong>Retrospective case-control study was conducted to document eligible cases. A total of 165 women with intact endometrioma(s) (END) were included in the final analysis. Controls were 196 cases with tubal disease as the sole cause of their infertility who underwent ART in the same time period. Cases and controls were matched for age, BMI and serum AMH concentrations. Ovarian stimulation characteristics and pregnancy outcomes including live birth data were documented for both groups.</p><p><strong>RESULTS: </strong>Despite similar demographic characteristics, significantly<strong> </strong>longer cycle duration and higher amounts of gonadotropin consumption was observed in END group compared to controls (p&lt;0.001). Significantly lower numbers of retrieved oocytes, mature oocytes and mature oocyte fraction (%, no of retrieved/mature) was detected in END group. There was no statistically significant difference in terms of fertilization, implantation and live birth rate per started cycle among groups. Cycle cancellations were also similar.</p><p><strong>CONCLUSION: </strong>In women with intact ovarian endometrioma(s) undergoing ART, oocyte quantity, especially mature oocyte yield was hampered. However, adequate number of mature oocytes, successful fertilization and satisfactory implantation rates might be possible contributing to acceptable live births. Further randomized controlled trials of patients with different sizes of endometrioma(s) would be needed to confirm our conclusions.</p>

Introduction Disseminated infection due to non-tuberculous mycobacteria has been a major factor of mortality and comorbidity in HIV patients. Until 2018, U.S. American guidelines have recommended antimycobacterial prophylaxis in patients with low CD4 cell counts, a practice that has not been adopted in Europe. This study aimed at examining the impact of disseminated NTM disease on clinical outcome in German HIV patients with a severe immunodeficiency. Materials and methods In this retrospective case control study, HIV patients with disseminated NTM disease were identified by retrospective chart review and matched by their CD4 cell counts to HIV patients without NTM infection in a 1:1 alocation. Primary endpoints were mortality and time to first rehospitalisation. In addition, other opportunistic diseases, as well as antimycobacterial and antiretroviral treatments were examined. Results Between 2006 and 2016, we identified 37 HIV patients with disseminated NTM disease. Most of them were suffering from infections due to M. avium complex (n = 31, 77.5%). Time to event analysis showed a non-significant trend to higher mortality in patients with disseminated NTM disease (p = 0.24). Rehospitalisation took place significantly earlier in patients with disseminated NTM infections (median 40.5 days vs. 109 days, p<0.0001). Conclusion In this retrospective case control study, we could demonstrate that mortality is not significantly higher in HIV patients with disseminated NTM disease in the ART era, but that they require specialised medical attention in the first months following discharge.

Abstract Pregnancy and childbearing are special reproductive events having an impact on women’s health and demographic trends. Reproductive health is not only linked to biological events of gestation and birth, but also are intricately linked to women`s status and their role in society. The current study focuses on the impact of bad obstetric history in the development of cardiometabolic risk factors. The present retrospective case-control study was conducted among Bhil tribal women of Rajasthan, India. A total of 287 women participated in this study which included 125 cases and 162 controls. Data on somatometric measurements, physiological measurements and lipid profile were recorded and analysed using SPSS version 25.0. The mean number of conceptions differed significantly between pregnancy in cases (5.06±1.85) and pregnancy in controls (3.19±1.56). Cases were characterised with significantly increased mean SBP (p=0.010), although the values (116.68±23.04) fell within the normal range. Bad obstetric history was found to be a risk factor for central obesity, hypertension and dyslipidemia among the Bhil women. It was also found to be relatively associated with adverse demographic/lifestyle variables which could enhance the effect of cardiometabolic risk factors. Women with bad obstetric history need special care and lifestyle variables need to be adjusted for better health outputs.

ObjectivesTo investigate whether calcium derangement was a specific feature of COVID-19 that distinguishes it from other infective pneumonias, and its association with disease severity.DesignA retrospective observational case–control study looking at serum calcium on adult patients with COVID-19, and community-acquired pneumonia (CAP) or viral pneumonia (VP).SettingA district general hospital on the outskirts of London, UK.Participants506 patients with COVID-19, 95 patients with CAP and 152 patients with VP.Outcome measuresBaseline characteristics including hypocalcaemia in patients with COVID-19, CAP and VP were detailed. For patients with COVID-19, the impact of an abnormally low calcium level on the maximum level of hospital care, as a surrogate of COVID-19 severity, was evaluated. The primary outcome of maximal level of care was based on the WHO Clinical Progression Scale for COVID-19.ResultsHypocalcaemia was a specific and common clinical finding in patients with COVID-19 that distinguished it from other respiratory infections. Calcium levels were significantly lower in those with severe disease. Ordinal regression of risk estimates for categorised care levels showed that baseline hypocalcaemia was incrementally associated with OR of 2.33 (95% CI 1.5 to 3.61) for higher level of care, superior to other variables that have previously been shown to predict worse COVID-19 outcome. Serial calcium levels showed improvement by days 7–9 of admission, only in survivors of COVID-19.ConclusionHypocalcaemia is specific to COVID-19 and may help distinguish it from other infective pneumonias. Hypocalcaemia may independently predict severe disease and warrants detailed prognostic investigation. The fact that decreased serum calcium is observed at the time of clinical presentation in COVID-19, but not other infective pneumonias, suggests that its early derangement is pathophysiological and may influence the deleterious evolution of this disease.Trial registration number20/HRA/2344.
