Background and Purpose: Risk of 30-day stroke readmission has been attributed to medical comorbidities, stroke severity, and hospitalization metrics. The leading etiologies appear to vary across institutions and remain a moving target. We hypothesized that patients with increased medical complexity have higher odds of 30-day readmission and the immediate time after discharge may be most vulnerable. We aimed to characterize patients with 30-day readmission after acute ischemic stroke (IS) and identify predictors of post-IS readmission. Methods: We performed a retrospective case-control study analyzing post-IS 30-day readmission between January 2016-December 2019 using data from Mount Sinai Hospital’s Get With The Guidelines database. We performed chi square analyses and multivariate adjusted logistic regression model including age, sex, coronary artery disease (CAD), renal insufficiency (RI), history of prior stroke or TIA, length of stay (LOS) > 7, and NIHSS ≥ 5. Results: 6.7% (n = 115) of 1,706 IS encounters had 30-day readmission. The 115 cases were compared to 1,591 controls without 30-day readmission. In our adjusted model, CAD (OR = 1.7, p = 0.01), history of prior stroke or TIA (OR = 1.6, p = 0.01), LOS >7 (OR = 1.7, p = 0.02), and NIHSS ≥ 5 (OR = 4.5, p < 0.001) predicted 30-day readmission. 65% (n = 75) of readmitted patients had readmission within 14 days post-discharge. Conclusions: Patients with post-IS 30-day readmission were more likely to have complex medical comorbidities and history of stroke or TIA compared to controls. Patients with more severe stroke and longer LOS may benefit from individualized transition of care plans and closer follow up during the vulnerable 30-day post-stroke period.

Objective: To identify predictors of thin endometrial lining in the first frozen embryo transfer cycles and to characterize the natural history of this condition over subsequent cycles. Design: Retrospective case-control study Conclusions: This study shows that prognosis after a diagnosis of thin endometrial lining is favorable. Lower weight and thinner fresh cycle lining are predictors of thin endometrial lining in FET cycles. Most importantly, women with a diagnosis of thin endometrial lining have similar live birth rates as those with adequate endometrial lining, although their time to achieve live birth is slightly longer.

Abstract Objective: To analyse the association between determinants of maternal deaths and obstetric haemorrhage in Padang, Indonesia.Methods: A retrospective case-control study was conducted in Padang, Indonesia from 2015 to 2019. Maternal deaths that occurred due to obstetric hemorrhage in Padang Health Department was compared to three mothers who survived from obstetric hemorrhage (controls) in Dr. M. Djamil General Hospital, Padang, Indonesia.Results: There were 20 deaths caused by obstetric hemorrhage during 2015 to 2019. Death records could only be found in 16 cases. The most common etiology of obstetric hemorrhage was uterine atony (62.5%). Determinants associated with maternal deaths due to obstetric hemorrhage were interval between pregnancies (p=0.045; OR:10.846), history of previous labour (p=0.003; OR:8.556), and antenatal care (p=0.003; OR:21.364). Age, parity, birth attendant, and mother’s educational level were not significantly associated with maternal deaths due to obstetric hemorrhage.Conclusion: Uterine atony was the most frequent etiology of maternal deaths due to obstetric hemorrhage. There was a significant association between pregnancy intervals, history of previous labour, and antenatal care with maternal deaths due to obstetric hemorrhage.Keywords: determinant, obstetric hemorrhage, maternal death. Abstrak Tujuan: Menganalisis hubungan determinan kematian maternal akibat perdarahan obstetri di Kota Padang.Metode: Sebuah studi retrospektif case-control dilakukan di Kota Padang dari tahun 2015–2019. Setiap kasus kematian ibu akibat perdarahan obstetri dari tahun 2015–2019 yang dilaporkan oleh Dinas Kesehatan Kota Padang dibandingkan dengan tiga kasus perdarahan obstetri yang tidak berakibat kematian di RSUP Dr. M. Djamil Padang. Analisis data menggunakan uji Chi-square.Hasil: Ada 20 kasus kematian akibat perdarahan obstetri selama tahun 2015–2019. Catatan kematian hanya dapat diperoleh pada 16 kasus. Etiologi terbanyak kematian akibat perdarahan obstetri ialah atonia uteri. Determinan yang berhubungan dengan kematian akibat perdarahan obstetri ialah jarak kehamilan (p=0.045; OR:10.846), riwayat persalinan sebelumnya (p=0.003; OR:8.556), dan antenatal care (p=0.003; OR:21.364). Tidak terdapat hubungan yang signifikan antara usia, paritas, penolong persalinan, dan tingkat pendidikan ibu dengan kematian maternal akibat perdarahan obstetri.Kesimpulan: Atonia uteri merupakan etiologi tertinggi kematian maternal akibat perdarahan obstetri. Ada hubungan yang signifikan antara jarak kehamilan, riwayat persalinan sebelumnya, dan antenatal care dengan kematian maternal akibat perdarahan obstetri.Kata kunci: determinan, kematian maternal, perdarahan obstetri.

Peri-implant bone loss leading to dental implant failure does not develop in the same way across subjects who apparently present the same condition—specifically, in the case of Down syndrome patients with the same genetic disorder—given that they do not necessarily develop immune–inflammatory disorders to the same extent. Methods: This retrospective case-control study was aimed at identifying the possible genes involved in implant failure in Down syndrome patients by matching the periodontal disease variable by means of a retrospective case-control study. This process involved using the functional analysis of gene expression software Transcriptome Analysis Console (TAC, Affymetrix, Thermo Fisher Scientific, Waltham, MA, USA) and a search for the possible candidate genes involved. Focus was placed on the 92 genes related to the inflammation identified from the TaqMan™ Array Plate Human Inflammation Kit (Thermo Fisher Scientific, Waltham, MA, USA). Results: Six genes showed statistically significant results (p < 0.05) in our comparison. Three of them—PLCG2 (p = 0.0333), ALOX5 (p = 0.03) and LTAH4 (p = 0.0081)—were overexpressed in the implant reject group, and the following three were down-regulated: VCAM1 (p = 0.0182), PLA2G2A (p = 0.0034) and PLA2G10 (p = 0.047). Conclusion: Statistically significant differences exist in the gene expression involved in osteoclastogenesis, inflammatory response and host defensive response.

Background and aims: Hepatitis B virus (HBV) is one of the important public health diseases in Iran. Therefore, to control the prevalence of the disease, knowledge is required regarding the risk factor of HBV. Accordingly, the aim of this study was to determine the risk factors of HB transmission. Methods: A retrospective case-control study was conducted on the possible risk factors of HBV transmission. To this end, a total of 171 patients with HBV infection and 171 controls from Rasoul-eAkram hospital were investigated during 2015-2018. All subjects were directly evaluated using a faceto-face questionnaire about demographic aspects. Finally, HBV infection and its risk factors among the subjects were detected using hepatitis B surface antigen test. Results: Overall, 171 HBV patients including 77 (42%) males and 93 (58%) females were evaluated. The mean age of the participants was 40 ± 13 years. Univariate logistic analysis showed that HBV infection in these cases was associated with addiction injection (odds ratio [OR] = 4.08, CI:1.3- 9.57), family history (OR = 4.52, CI: 1.27-10.7), and having a history of blood transfusion (OR = 3.16, CI: 1.52-5.37). There were no significant relationships between the liver function tests, alcohol consumption, the history of dental visits, and HBV participants. In addition, the logistic-regression model proved that patients with a history of HBV-infected parents (At least one of them) and addiction injection were severely subject to HB infection. In other words, there was a significant association between a history of HBV-infected parents and addiction injection and HB infection. Conclusion: In general, HBV infection was strongly related to having a family member infected with hepatitis B, suffering from addiction injection, and having blood injection.

A retrospective case-control study of necrotizing enterocolitis (NEC) was conducted among infants weighing &gt;2,000 g at birth. Twenty-three infants met the NEC criteria for inclusion in the study; 12 weighed 2,001 to 2,500 g at birth and 11 weighed &gt;2,500 g at birth. Hypoglycemia occurred in 7/12 (55%) infants weighing 2,001 to 2,500 g and in 4/35 (11%) control subjects (P &lt; .02). In infants weighing &gt;2,500 g at birth, polycythemia (occurring in 7/12 study infants (58%) and 5/32 (16%) control infants) and respiratory distress (3/11 study infants (27%) and 0 control subjects) were significantly associated with NEC (P &lt; .02). Larger infants with a history of perinatal stress and/or physiologic immaturity are likely to be at greater risk for NEC than their normal counterparts.
