This systematic review and meta-analysis aimed to give an overview on the postoperative outcome after a minimally invasive (ie, laparoscopic and robot-assisted) central pancreatectomy and open central pancreatectomy with a specific emphasis on the postoperative pancreatic fistula. For benign and low-grade malignant lesions in the pancreatic neck and body, central pancreatectomy may be an alternative to distal pancreatectomy. Exocrine and endocrine insufficiency occur less often after central pancreatectomy, but the rate of postoperative pancreatic fistula is higher.

An electronic search was performed for studies on elective minimally invasive central pancreatectomy and open central pancreatectomy, which reported on major morbidity and postoperative pancreatic fistula in PubMed, Cochrane Register, Embase, and Google Scholar until June 1, 2021. A review protocol was developed a priori and registered in PROSPERO as CRD42021259738. A meta-regression was performed by using a random effects model.

Overall, 41tic fistula (random effects model 0.16 [0.10; 0.24] with P= .789), major morbidity (random effects model 0.20 [0.15; 0.25] with P= .410), and new-onset diabetes mellitus (random effects model 0.04 [0.02; 0.07] with P= .651).

In selected patients and in experienced hands, minimally invasive central pancreatectomy is a safe alternative to open central pancreatectomy for benign and low-grade malignant lesions of the neck and body. Ideally, further research should confirm this with the main focus on postoperative pancreatic fistula and endocrine and exocrine insufficiency.

The incidence of adenocarcinoma of the esophagogastric junction (AEG) has significantly increased. However, the best surgical treatment for AEG typeII is still the subject of current research. The goal of this retrospective cohort study is to compare survival and recurrence rates in patients, who underwent either thoracoabdominal esophagectomy (TAE) or transhiatal extended gastrectomy (TEG).

The study is based on acohort of 272patients diagnosed with AEG typeII between 2002 and 2020, recorded by apopulation-based clinical cancer registry. Of the included patients 63underwent TAE and 209 TEG. In order to compare overall survival, recurrence rates, and recurrence free survival, we applied the Kaplan-Meier method, univariable and multivariable Cox regression.

Our analysis showed no statistically significant difference concerning overall survival (p = 0.333). However atendency towards higher survival rates after TAE for the period from 2016-2020 (p = 0,058) is possible. In contrast asignificant difference concerning higher cumulative recurrence rates after TAE was found after Kaplan-Meier analysis (p = 0.049). This trend was not observed for the time after 2016 (p = 0.993), in which over 50% of TAE were performed. No differences were found regarding recurrence-free survival (p = 0.772).

Our findings in arather small cohort are concordant with most studies showing no differences or atrend towards better survival after TAE. Other studies found no significant difference regarding recurrence-free survival as well. In conclusion, no significant differences were found between TEG and TAE in surgical treatment of AEG typeII.
Our findings in a rather small cohort are concordant with most studies showing no differences or a trend towards better survival after TAE.

In conclusion, no significant differences were found between TEG and TAE in surgical treatment of AEG type II.Cytoreductive surgery, often in combination with hyperthermic intraperitoneal chemotherapy (HIPEC), has been instrumental in improving the survival of patients with peritoneal metastases from colorectal cancer. Recent studies have highlighted the benefits of complete cytoreduction, while the role of the HIPEC treatment remains unclear. An oxaliplatin-based HIPEC over 30 min could not achieve any clear benefits in studies on colorectal cancer, neither in the therapeutic nor in the prophylactic setting, but caused relevant side effects and increased the morbidity. The negative results of these studies with respect to oxaliplatin-based HIPEC require critical appraisal; however, they should by no means be regarded as a general setback for surgical treatment of peritoneal metastases and be misunderstood as a general failure of this treatment. While HIPEC after complete surgical cytoreduction of peritoneal metastases from colorectal cancer requires further research, cytoreductive surgery should still be regarded as a highly effective treatment for suitable patients with limited abdominal tumor dissemination.COVID-19 vaccine hesitancy is still widespread. buy CCT251545 During the pandemic, the internet has been the preferred channel for health-related information, especially for less-educated citizens who tend to be the most hesitant about vaccination. A well-structured web communication strategy could help both to overcome vaccine hesitancy and to ensure equity in healthcare service access. This study investigated how the various regional and local health authorities in Italy used their institutional websites to inform users about COVID-19 vaccinations between March and April 2021. We browsed 129 institutional websites, checking the availability, quality and quantity, actionability and readability of information using a literature-based common grid. Descriptive statistics and statistical tests were performed. The online public dissemination of COVID-19 vaccination information in Italy was fragmented, both across and within regions. The side effects of vaccinations, were often not reported on the websites, thus missing an opportunity to enhance vaccination uptake. More focus should also be placed on readability, since readability indexes showed that they were difficult to understand. Our research revealed that several actions could be implemented to enhance online communication on COVID-19 vaccination. For instance, simplifying texts can make them more understandable and the information reported actionable.
Acupuncture is one of the most popular complementary and alternative treatments for knee osteoarthritis (KOA). There are many methods of acupuncture in the treatment of KOA, and the effects are different. According to our clinical observations and researches, it is found that manual acupuncture (MA), electro-acupuncture (EA), and warm acupuncture (WA) are used more frequently in the treatment of KOA, and the curative effects are satisfactory. However, there is currently a lack of efficacy comparison of efficacy between different acupuncture treatments, as well as a lack of standardized clinical research on the acupuncture treatment of KOA. Therefore, we will carry out a high-quality clinical randomized controlled trial to research the effect laws of MA, EA, and WA on KOA.

A total of 200 eligible participants with KOA will be randomly assigned to group A, B, C, or D in a ratio of 1111. Patients in group A will receive MA, while those in group B, group C, and group D will be treated with EA, WA, and sham acupuncture (SA), respectively. Patients will be treated with acupuncture once a day, 30 min per session, 5 sessions per week for 4 weeks. The primary outcome is the change of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at week 4. The secondary outcomes include WOMAC, visual analog scale (VAS), Arthritis Quality of Life Measurement Scale Simplified Scale (AIMS2-SF), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Credibility/Expectancy Questionnaire. The evaluation will be performed at baseline and weeks 4, 8, and 12 respectively after randomization.

This is a randomized controlled trial. We will observe the clinical effect of MA, EA, and WA on KOA to research the effect laws of these three acupuncture treatments on KOA and set up standardized treatment programs for acupuncture for KOA.

They have been intensively studied in laboratory-generated and -evolved mutants, but emergent adaptation mechanisms to auxotrophy have not been systematically addressed. Here, we investigated auxotrophies in bacteria isolated from Arabidopsis thaliana leaves and found that up to half of the strains have auxotrophic requirements for biotin, niacin, pantothenate and/or thiamine. We then explored the genetic basis of auxotrophy as well as traits that co-occurred with vitamin auxotrophy. We found that auxotrophic strains generally stored coenzymes with the capacity to grow exponentially for 1-3 doublings without vitamin supplementation; however, the highest observed storage was for biotin, which allowed for 9 doublings in one strain. In co-culture experiments, we demonstrated vitamin supply to auxotrophs, and found that auxotrophic strains maintained higher species richness than prototrophs upon external supplementation with vitamins. Extension of a consumer-resource model predicted that auxotrophs can utilize carbon compounds provided by other organisms, suggesting that auxotrophic strains benefit from metabolic by-products beyond vitamins.In this work, we aim to use the optical amplifiers, directional couplers and phase modulators to build the electro-optical gates. Thanks to the 2-layer-multilayer-perceptron structure, the inversion of matrix is performed to obtain the coupling ratio of the directional couplers and the phase delay of the phase modulators. The electro-optical OR, AND, XOR, NAND, NOR and XNOR gates are demonstrated. Moreover, we not only study the results under the ideal condition of device, but also discuss the imperfect situation with 1% error of fabrication or operation to study the tolerance of this system. Through our simulation results, the visibility of the gate output can be higher than 0.83. The gates can be fabricated in a silicon-based chip to develop the integrated optics computing system.
Logistical and economic barriers hamper community-level surveillance for antimicrobial-resistant bacteria in low-income countries. Latrines are commonly used in these settings and offer a low-cost source of surveillance samples. It is unclear, however, whether antimicrobial resistance prevalence estimates from latrine samples reflect estimates generated from randomly sampled people.

We compared the prevalence of antimicrobial-resistant enteric bacteria from stool samples of people residing in randomly selected households within Kibera-an informal urban settlement in Kenya-to estimates from latrine samples within the same community. Fecal samples were collected between November 2015 and Jan 2016. Presumptive Escherichia coli isolates were collected from each household stool sample (n = 24) and each latrine sample (n = 48), resulting in 8935 and 8210 isolates, respectively. Isolates were tested for resistance to nine antibiotics using the replica-plating technique. Correlation- and Kolmogorov-Smirnov (K-S) tests were used to compare results.
