We investigated changes in post-traumatic stress symptoms (PTSS) and depressive symptoms from 18 to 31 months after the 2015 earthquake in Nepal and explored potential risk factors associated with the change in psychiatric symptoms. This study comprised of 515 adolescents, aged 11-17 years from two earthquake-affected areas, one severely affected than the other. The psychiatric symptoms were assessed using the standardized Child Post-traumatic Stress Disorder Scale and the Depression Self-Rating Scale. No significant change was observed in the prevalence of PTSS and depressive symptoms from 18 to 31 months after the earthquake. Living in severely affected area and exposure to trauma after the earthquake were associated with adolescents who developed chronic or delayed PTSS and depressive symptoms. The study findings highlight the need for disaster preparedness and early interventions that strengthen support at various levels.Ultrafast Ca2+ imaging using low-affinity fluorescent indicators allows the precise measurement of the kinetics of fast Ca2+ currents mediated by voltage-gated Ca2+ channels. Thus far, only a few indicators provided fluorescence transients with sufficient signal-to-noise ratio necessary to achieve this measurement, with Oregon Green BAPTA-5N exhibiting the best performance. Here we evaluated the performance of the low-affinity Ca2+ indicator Cal-520FF to record fast Ca2+ signals and to measure the kinetics of Ca2+ currents. Compared to Oregon Green BAPTA-5N and to Fluo4FF, Cal-520FF offers a superior signal-to-noise-ratio providing the optimal characteristics for this important type of biophysical measurement. This ability is the result of a relatively high fluorescence at zero Ca2+, necessary to detect enough photons at short exposure windows, and a high dynamic range leading to large fluorescence transients associated with short Ca2+ influx periods. We conclude that Cal-520FF is at present the optimal commercial low-affinity Ca2+ indicator for ultrafast Ca2+ imaging applications.

Transanal TME (TaTME) was introduced to improve access to the pelvis in difficult cases (male sex, obesity and mid to low rectal cancers) and reduce the risk of anastomotic leak by avoiding cross stapling. In April 2018 theNorwegian hospital to whom all local; recurrences for rectal cancer are referredreported an unexpected rise in early multifocal local recurrences of 9.5% following TaTME compared with 3.4% following conventional TMEleading to a nationwide moratorium on the procedure and ending, in an editorial published on the British Journal of Surgery in August 2020, by saying that other countries should consider theissue in the context of local practicesand results. There are limited data concerning oncological outcomes of TaTME compared to conventional TME. The aim of this study was to report perioperative and oncological outcomes for patients with rectal cancer treated with TaTME in a high-volume, experienced UK centre.

From January 2015 to January 2020 consecutive patients with histologically confirmed rectal cancer having TaTME at Worcestershire Royal Hospital NHS were prospectively entered into an online international registry. Patients were followed according to local protocol with clinical examination, tumour markers, endoscopy and radiology.

Seventy patients underwent TaTME for rectal cancer.The median distance of the tumour from the anorectal junction was 4 cm (IQR 2-5). The mesorectal margin was involved in 20 (1%) patients, all of whom received neoadjuvant chemoradiotherapy. Overall survival was94% at a median follow-up of 15months (IQR 9-31months). Distant recurrence occurred in 12 (17%) of patients at a median of 14 months (IQR 10-17 months). The 18-month stoma-free survival rate was 66%.

A local recurrence rate of 5.7% supports the oncological safety of TaTME for rectal cancer.

Many studies have described the relationship between kidney stones and stroke, but the results are controversial, so we conducted this meta-analysis to estimate the relationship between kidney stones and the risk of developing stroke.

Studies were marked with a comprehensive search of PubMed, EMBASE, Google, and ISI Web of Science databases through 25 March 2020. selleck products Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted, and a random-effects model or fix-effects model was used to compute the pooled combined risk estimate. Heterogeneity was reported as I

. We performed subgroup and sensitivity analysis to assess potential sources of heterogeneity.

Eight studies of seven articles involving 3,526,808 participants were included in the meta-analysis. Overall, kidney stones were associated with a moderate risk of stroke incidence (HR, 1.24; 95% CI, 1.11-1.40; I

=79.6%; p=0.000). We conducted a sensitivity analysis by removing the studies that had a high risk of bias. Heterogeneity subsequently decreased significantly, while an increased risk of stroke in patient with kidney stones was again demonstrated (HR, 1.16; 95% CI, 1.11-1.23; I

=28.7%; p=0.000). Stratifying analysis showed that the results were more pronounced for ischemic stroke (HR, 1.14; 95% CI, 1.08-1.22; I

=15.6%; p=0.00) and the follow-up duration ≥10 years (HR, 1.18; 95% CI, 1.10-1.27; I

=31.6%; p=0.003).

Our meta-analysis suggests that patients with kidney stones may have a modestly increased risk of developing stroke, especially in ischemic stroke. More large-scaled and clinical trials should be done to identify the relative impact of kidney stones on stroke outcomes in the future.
