Background: India has seen a surge in COVID-19 associated mucormycosis (CAM) cases during the second wave of the pandemic. We conducted a study to determine independent risk factors for CAM. Methods: We performed a retrospective case control study in a tertiary care private hospital in Pune, India. Fifty-two cases of CAM were compared with 166 concurrent controls randomly selected from the COVID-19 admissions during the same time period. Association of demographic factors, comorbidities, cumulative steroid dose used (calculated as dexamethasone equivalent), maximum respiratory support required, use of injectable/oral anticoagulation, and use of aspirin with CAM was assessed by univariate and multivariate logistic regression. Results: A total of 218 subjects (52 cases; 166 controls) were studied. Any diabetes (pre-existing diabetes and new onset diabetes during COVID-19) was noted in a significantly higher proportion of cases (73.1%, 45.8% P<0.001) and cumulative dexamethasone dose used in cases was significantly greater (97.72 mg vs 60 mg; P=0.016). In a multivariate regression analysis cumulate dexamethasone dose >120 mg (OR 9.03, confidence interval 1.75-46.59, P=0.009) and any diabetes (OR 4.78, confidence interval 1.46-15.65, P=0.01) were found to be risk factors for CAM. While use of anticoagulation (OR 0.01, confidence interval 0.00-0.09, P<0.001) and use of aspirin (OR 0.02, confidence interval 0.01-0.07, P<0.001) were found to be protective against CAM. Conclusion: Diabetes mellitus and cumulative dose of dexamethasone greater than 120 mg (or equivalent dose of other corticosteroid) were associated with an increased risk of CAM while use of aspirin and anticoagulation were associated with a lower risk.

Abstract Background Progressive myelomalacia (PMM) is a usually fatal complication of acute intervertebral disc extrusion (IVDE) in dogs but its risk factors are poorly understood. The objective of this retrospective case-control study was to identify risk factors for PMM by comparing dogs with complete sensorimotor loss following IVDE that did and did not develop the disease after surgery. We also investigated whether any risk factors for PMM influenced return of ambulation. Medical records of client-owned dogs with paraplegia and loss of pain perception that underwent surgery for IVDE from 1998 to 2016, were reviewed. Dogs were categorized as PMM yes or no based on clinical progression or histopathology. Walking outcome at 6 months was established. Signalment, onset and duration of signs (categorized), steroids, non-steroidal anti-inflammatory drugs (yes or no), site of IVDE (lumbar intumescence or thoracolumbar) and longitudinal extent of IVDE were retrieved and their associations with PMM and walking outcome were examined using logistic regression. Results One hundred and ninety seven dogs were included, 45 with and 152 without PMM. A 6-month-outcome was available in 178 dogs (all 45 PMM dogs and 133 control dogs); 86 recovered walking (all in the control group). Disc extrusions at the lumbar intumescence were associated with PMM (p = 0.01, OR: 3.02, CI: 1.3–7.2). Surgery performed more than 12 h after loss of ambulation was associated with PMM (OR = 3.4; CI = 1.1–10.5, p = 0.03 for 12-24 h and OR = 4.6; CI = 1.3–16.6, p = 0.02 for the > 24 h categories when compared with the ≤12 h category). Treatment with corticosteroids was negatively associated with PMM (OR: 3.1; CI: 1.3–7.6, p = 0.01). The only variable to affect walking outcome was longitudinal extent of IVDE (OR = 2.6; CI = 1.3–5.3, p = 0.006). Conclusion Dogs with lumbar intumescence IVDE are at increased risk of PMM. Timing of surgery and corticosteroid use warrant further investigations. PMM and recovery of walking are influenced by different factors.

Abstract Background Evidence for periconceptional or prenatal environmental risk factors for the development of congenital diaphragmatic hernia (CDH) is still scarce. Here, in a case-control study we investigated potential environmental risk factors in 199 CDH patients compared to 597 healthy control newborns. Methods The following data was collected: time of conception and birth, maternal BMI, parental risk factors such as smoking, alcohol or drug intake, use of hairspray, contact to animals and parental chronic diseases. CDH patients were born between 2001 and 2019, all healthy control newborns were born in 2011. Patients and control newborns were matched in the ratio of three to one. Results Presence of CDH was significantly associated with maternal periconceptional alcohol intake (odds ratio = 1.639, 95% confidence interval 1.101–2.440, p = 0.015) and maternal periconceptional use of hairspray (odds ratio = 2.072, 95% confidence interval 1.330–3.229, p = 0.001). Conclusion Our study suggests an association between CDH and periconceptional maternal alcohol intake and periconceptional maternal use of hairspray. Besides the identification of novel and confirmation of previously described parental risk factors, our study underlines the multifactorial background of isolated CDH.

Abstract Introduction Nephrolithiasis is pathological calcification in the excretory passages of the body and is prevalent among 7.6% of Indians. We aimed to study the various risk factors associated with renal stones from India. Method It was a hospital-based case-control study conducted over 18 months in a tertiary hospital in Delhi. Cases were defined as patients with renal stones diagnosed on the basis of history and radiological examination. Controls were similar to cases in all respects except for the diagnosis and selected from the hospital. A total of 18 risk factors, including age, gender, heavy metals, stress, metabolic factors, alcohol intake, dietary habits, co-morbidities, etc. were assessed. Logistic regression analysis was performed to calculate the strength of the risk associations. Results In the analysis of 60 cases and controls, we found 6 times, 5.5 times, and 2.4 times increased odds of renal stones in patients with increased arsenic, cadmium, and lead concentrations in blood, respectively. Similarly, there are 3 times increased odds of renal stones in patients suffering from stress. Conclusions Exposure to smoke, occupation dust, and contaminated water may lead to an increased ingestion/inhalation of heavy metals like cadmium, arsenic, and predisposing people to an increased risk of renal stones.

OBJECTIVE: To determine patient and perioperative characteristics associated with unexpected postoperative clinical deterioration as determined for the need of a postoperative emergency response team (ERT) activation. DESIGN: Retrospective case–control study. SETTING: Tertiary academic hospital. PARTICIPANTS: Patients who underwent general anaesthesia discharged to regular wards between 1 January 2013 and 31 December 2015 and required ERT activation within 48 postoperative hours. Controls were matched based on age, sex and procedure. MAIN OUTCOME MEASURES: Baseline patient and perioperative characteristics were abstracted to develop a multiple logistic regression model to assess for potential associations for increased risk for postoperative ERT. RESULTS: Among 105 345 patients, 797 had ERT calls, with a rate of 7.6 (95% CI, 7.1–8.1) calls per 1000 anaesthetics (0.76%). Multiple logistic regression analysis showed the following risk factors for postoperative ERT: cardiovascular disease (odds ratio [OR], 1.61; 95% CI, 1.18–2.18), neurological disease (OR, 1.57; 95% CI, 1.11–2.22), preoperative gabapentin (OR, 1.60; 95% CI, 1.17–2.20), longer surgical duration (OR, 1.06; 95% CI, 1.02–1.11, per 30 min), emergency procedure (OR, 1.54; 95% CI, 1.09–2.18), and intraoperative use of colloids (OR, 1.50; 95% CI, 1.17–1.92). Compared with control participants, ERT patients had a longer hospital stay, a higher rate of admissions to critical care (55.5%), increased postoperative complications, and a higher 30-day mortality rate (OR, 3.36; 95% CI, 1.73–6.54). CONCLUSION: We identified several patient and procedural characteristics associated with increased likelihood of postoperative ERT activation. ERT intervention is a marker for increased rates of postoperative complications and death.

Asfiksia perinatal merujuk pada kekurangan oksigen selama persalinan, sehingga berpotensi menyebabkan kematian dan kecacatan. WHO memperkirakan  4 juta anak terlahir dengan asfiksia setiap tahun, dimana 1 juta di antaranya meninggal dan 1 juta anak bertahan hidup dengan gejala sisa neurologis yang parah. Penelitian ini bertujuan untuk menganalisis faktor risiko fetal dan tali pusat pada asfiksia neonatal.Penelitian dilakukan di lakukan di RS Dr Moewardi Surakarta dengan pendekatan  quantitative retrospective case control study. Data diambil dari rekam medis antara  tahun 2013-2018. Penelitan ini melibatkan  264 neonatal yang terdiri dari 88 kelompok kasus dan 176  kelompok control. Kelompok kasus adalah bayi dengan diagnosa  asfiksia yang  dilakukan analisis terhadap faktor risiko fetal, sedangkan bayi yang tidak mengalami asfiksia dijadikan  kelompok kontrol. Hasil analisis statistik uji Chi-Square dan Fisher Exact ditemukan bahwa  kelahiran prematur (OR 2,07 CI 95% P 0,02), persalinan dengan tindakan (OR 3,61 CI 95% P 0,00), berat bayi (OR 2,85 CI 95% P 0,00), posisi janin (OR 2,37 CI 95% P 0,05), tali pusat ( QR 3,071 CI 95%  P 0,01)  berisiko terhadap insiden asfiksia perinatal. Air ketuban yang bercampur meconium (OR 1,51 CI 95% P 0,16) tidak memiliki risiko  dengan Asfiksia perinatal. Kesimpulan: Risiko terhadap insiden asfiksia perinatal  meliputi kelahiran prematur, persalinan dengan tindakan, berat bayi, posisi janin,  dan tali pusat.Perinatal asphyxia refers to a lack of oxygen during labor, which has the potential to cause death and disability. WHO estimates  4 million children born with asphyxia each year, in  which 1 million dies and 1 million survive with severe neurological sequelae. This study aims to analyze fetal and umbilical risk factors in neonatal asphyxia.This research is a quantitative retrospective case-control study, which was conducted at The Dr. Moewardi  hospital,  Surakarta. Data was taken from  medical records from 2013-2018. The case group was patients diagnosed  asphyxia, while those who did not experience asphyxia were treated as a control group.  A total of 264  samples, consisting of 88 case group respondents and 176 control group respondents. Statistical analysis Chi- Square and Fisher Exact found that preterm birth (OR 2.07 CI 95% P 0.02), labor with instrument or complication (OR 3.61 CI 95% P 0.00), infant weight (OR 2.85 CI 95% P 0, 00), fetal position (OR 2.37 CI 95% P 0.05), umbilical cord (QR 3.071 CI 95% P 0.01) are at risk for the incidence of perinatal Asphyxia. The amniotic fluid mixed with meconium (OR 1.51 CI 95% P 0.16) has no risk with perinatal asphyxia.The risk factors of incidences of perinatal asphyxia were  preterm birth, labor with instrument or complication, baby weight, fetal position and umbilical cord.
