Prospective Cohort Study

Secret History: Return of the Black Death Channel 4, 7-8pm In 1348 the Black Death swept through London, killing people within days of the appearance of their first symptoms. Exactly how many died, and why, has long been a mystery. This Secret History documentary follows experts as they pick through the evidence and reveal why the plague killed on such a scale. And they ask, what might be coming next?

Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

Clinical assessment of T and N stages in rectal cancer is important to guide decision-making. The present study aimed to assess the accuracy of the clinical T and N staging of rectal cancer compared to the pathological staging and their overall agreement in a large cohort of patients.This retrospective study used data from the National Cancer Database (NCDB) between 2004 and 2017. Patients with non-metastatic rectal adenocarcinoma who did not receive neoadjuvant therapy were reviewed and the clinical T and N stages were compared to their pathologic counterparts. The overall concordance between clinical and pathologic assessments was calculated using Kappa coefficient.The study included 8929 patients (57.3% male) with a mean age of 64 years. Clinical T stage and N stage were identical to pathologic stages in 70.3% and 77.6% of patients, respectively. Sensitivity and specificity of the clinical assessment of N stage was 35.2% and 95.5%, respectively. Concordance between the clinical and pathologic stages was moderate for the T stage (kappa = 0.575) and fair for the N stage (kappa = 0.346). Pathologic T4 stage (OR: 2.12, p < 0.0001), poorly differentiated adenocarcinoma (OR: 1.45, p = 0.026), lymphovascular invasion (OR: 4.5, p < 0.001), and longer time from diagnosis to first treatment (OR = 0.996, p = 0.046) were the independent predictors of N stage discrepancy.There was a moderate agreement between the clinical and pathologic T stages and a fair agreement between the clinical and pathologic N stages. The clinical assessment of the N stage was highly specific yet had low sensitivity.

Gastric Mucosal Changes and Ghrelin Expression and Their Relation to Weight Reduction After Sleeve Gastrectomy

AIM Anterior rectocele is usually an asymptomatic condition in many women, yet it can be associated with obstructed defaecation syndrome (ODS). Transperineal repair of rectocele (TPR) has been followed by variable rates of improvement in ODS. The present pilot randomized clinical trial aimed to evaluate the outcome of TPR with vertical plication (VP) of the rectovaginal septum compared to horizontal plication (HP). METHODS Adult women with anterior rectocele were recruited to the study and were randomly allocated to one of two equal groups. The first group underwent TPR with VP of the rectovaginal septum and the second group underwent TPR with HP. The main outcome measures were improvement in ODS, recurrence of rectocele, complications and dyspareunia. RESULTS The trial included 40 female patients with anterior rectocele. There was no significant difference between the two groups regarding the postoperative Wexner score. Complete cure and significant improvement in ODS symptoms were comparable after the two techniques. The reduction in rectocele size after HP was significantly greater than after VP (1.7 vs. 2.6, P < 0.0001). Significant improvement in dyspareunia was recorded after HP (P = 0.001) but not after VP (P = 0.1). There was no significant difference between the two groups with regard to operating time, complications and recurrence. CONCLUSION VP and HP of the rectovaginal septum in TPR were associated with a comparable improvement in ODS symptoms and similar complication rates. HP was followed by a greater reduction in the rectocele size and greater improvement in dyspareunia than VP.
