Risks along with advantages of systematic lymphadenectomy through time period debulking surgical treatment with regard to sophisticated high grade serous ovarian cancers.
The prevalence of cholelithiasis and gallbladder cancer may be different across ethnic groups.

To study the prevalence of cholelithiasis and gallbladder cancer among Aymara individuals.

An abdominal ultrasound was carried out in a sample of 182 Aymara women aged 46 ± 16 years and 76 Aymara men aged 55 ± 16 years. In addition, the histopathological reports of both patients with a history of previous cholecystectomy and those operated after the study were reviewed.

Ultrasound was normal in 150 participants (58%), 76 had cholelithiasis (30%) and 32 (12%) had a history of cholecystectomy. Pathological reports of the excised gallbladder were available for 106 cases and showed a chronic cholecystitis in 98% of cases. Gallbladder cancer was not reported.

There is a 42% prevalence of cholelithiasis and no gallbladder cancer in this sample of Aymara population.

In December 2019, coronavirus disease 2019 (COVID-19) emerged in Wuhan city and spread rapidly throughout China and the world.

To describe the clinical features, risk factors, and predictors of hospitalization in adult patients treated for acute respiratory infections associated with coronavirus SARS-CoV-2.

Descriptive prospective study of ambulatory and hospitalized adult patients with confirmed COVID-19 attended between April 1 and May 31, 2020. Clinical features, chronic comorbidities and demographic data were recorded, and patients were followed for two months as outpatients.

We assessed 1,022 adults aged 41 ± 14 years (50% men) with laboratory-confirmed COVID-19. One-third had comorbidities, specially hypertension (12.5%), hypothyroidism (6.6%), asthma (5.4%) and diabetes (4.5%). Hospital admission was required in 11%, 5.2% were admitted to critical care unit and 0.9% were connected to mechanical ventilation. Common symptoms included fatigue (55.4%), fever (52.5%), headache (68.6%), anosmia/dysgeusia (53.2%), dry cough (53.4%), dyspnea (27.4%) and diarrhea (35.5%). One third of patients reported persistence of symptoms at one-month follow-up, specially fatigue, cough and dyspnea. In the multivariate analysis, age, fever, cough, dyspnea and immunosuppression were associated with hospitalization and ICU admission. Age, male sex and moderate-severe dyspnea were associated with requirement of mechanical ventilation. The main predictors of prolonged clinical course were female sex, presence of comorbidities, history of dyspnea, cough, myalgia and abdominal pain.

Clinical features of COVID-19 were highly unspecific. Prediction models for severity, will help medical decision making at the primary care setting.

This prospective observational study aimed to clarify the incidence and independent risk factors of wound infection after laparoscopic surgery for primary colonic and rectal cancer.

A prospective surveillance of surgical site infection (SSI) was conducted in consecutive patients with primary colorectal cancer, who underwent elective laparoscopic surgery in a single comprehensive cancer center between 2005 and 2014. The outcomes of interest were the incidence and risk factors of wound infection.

In total, 3170 patients were enrolled in the study. The overall incidence of wound infection was 3.0%. The incidence of wound infection was significantly higher in rectal surgery than in colonic surgery (4.7 vs. Laduviglusib mouse 2.1%,
 < 0.001). In rectal surgery, independent risk factors for developing wound infection included abdominoperineal resection (
 < 0.001, odds ratio [OR] = 11.4, 95% confidence interval [CI] 5.04-24.8), body mass index (BMI) ≥ 25kg/m
(
 = 0.041, OR = 1.97, 95% CI, 1.03-3.76), and chemoradiotherapy (
 = 0.032, OR = 2.18, 95% CI, 1.07-4.45). In laparoscopic colonic surgery, no significant risk factors were identified.

Laparoscopic rectal surgery has a higher risk of wound infection than colonic surgery. Laparoscopic rectal surgery involving abdominoperineal resection, patients with higher BMI, and chemoradiotherapy requires careful observation in wound care and countermeasures against wound infection.

ASCC is strongly associated with HIV and there appears to be increasing numbers of younger male persons living with HIV (PLWH) diagnosed with ASCC. This is a retrospective cohort study of HIV positive and HIV negative patients diagnosed with primary ASCC between January 2000 and January 2020 in a demographic group with high prevalence rates of HIV. One Hundred and seventy six patients were included, and clinical data was retrieved from multiple, prospective databases. A clinical subgroup was identified in this cohort of younger HIV positive males who were more likely to have had a prior diagnosis of Anal Intraepithelial Neoplasia (AIN). Gender and HIV status had no effect on staging or disease-free survival. PLWH were more likely to develop a recurrence (p  less then  0.000) but had a longer time to recurrence than HIV negative patients, however this was not statistically significant (46.1 months vs. 17.5 months; p = 0.077). Patients known to have a previous diagnosis of AIN were more likely to have earlier staging and local tumour excision. Five-year Disease-Free Survival was associated with tumour size and the absence of nodal or metastatic disease (p  less then  0.000).[This corrects the article DOI 10.1371/journal.ppat.1009209.].[This corrects the article DOI 10.1371/journal.pone.0239636.].The massive growth of potentially toxic cyanobacteria in water supply reservoirs, such as Legedadi Reservoir (Ethiopia), poses a huge burden to water purification units and represents a serious threat to public health. In this study, we evaluated the efficiency of the flocculants/coagulants chitosan, Moringa oleifera seed (MOS), and poly-aluminium chloride (PAC) in settling cyanobacterial species present in the Legedadi Reservoir. We also tested whether coagulant-treated reservoir water promotes cyanobacteria growth. Our data showed that suspended solids in the turbid reservoir acted as ballast, thereby enhancing settling and hence the removal of cyanobacterial species coagulated with chitosan, Moringa oleifera seed, or their combination. Compared to other coagulants, MOS of 30 mg/L concentration, with the removal efficiency of 93.6%, was the most effective in removing cyanobacterial species without causing cell lysis. Contrary to our expectation, PAC was the least effective coagulant. Moreover, reservoir water treated with MOS alone or MOS combined with chitosan did not support any growth of cyanobacteria during the first two weeks of the experiment.
