e., without having to study the full generic dynamical system). Our results extend and generalize previous results for a stable resident equilibrium (particularly, Geritz in J Math Biol 50(1)67-82, 2005; Dercole and Geritz in J Theor Biol 394231-254, 2016) to non-equilibrium resident population dynamics as well as resident dynamics with stochastic (or deterministic) drivers.

Several factors may contribute to bile duct injury (BDI) repair failure. The objective of our study was to evaluate factors that contribute to the loss of patency and influence the actuarial patency rate of BDI repairs in an 11-year period.

Retrospective review study of patients who underwent a hepaticojejunostomy for a type E Bismuth-Strasberg BDI (2008-2019). The outcomes are the following primary patency attained, loss of primary patency, and actuarial primary patency rate. Logistic regression for loss of patency and Cox regression for actuarial patency rate were used.

Seventy-nine patients (age 42.3 ± 15.8years, 81% female) were studied. Most common index operation was open cholecystectomy (60.8%). Most common Bismuth-Strasberg lesion was E4 (38%). Primary patency was 93.4%. Mean follow-up was 36 ± 34months. Ten-year actuarial patency was 53.9%. Factors associated with loss of patency were vasculobiliary injury, biliary stents, and 90-day biliary complications (univariate); number of surgeries before repair and postoperative cholangitis (univariate and multivariate) (p < 0.05). Factors that impacted actuarial patency rate were (univariate analysis) 90-day biliary complications; postoperative cholangitis and index treatment period stenosis (p < 0.05). No factors impacted actuarial patency rate in multivariate analysis.

Postoperative cholangitis is associated with loss of patency and had potentially detrimental effect on the actuarial patency rate in BDI repair.

We applied a rapid diagnostic test (RDT) on clinical samples with an elevated likelihood of carbapenemase-producing bacteria and documented its impact on antibiotic treatment decisions. Among 38 patients, twelve tested positive for infections caused by carbapenemase-producing bacteria (31.6%), mainly in blood cultures. KPC (n = 10) was more frequent than OXA-48 (n = 2). RDT-based carbapenemase detection led to a treatment modification to ceftazidime/avibactam-containing regimens in all patients before detailed antibiotic testing results became available. Eleven patients (92%) survived the acute infection, whereas one patient with a ceftazidime/avibactam- and colistin-resistant OXA-48-positive isolate died.To investigated the molecular epidemiology and in vitro antifungal susceptibility of Cryptococcus isolates from West China Hospital from HIV and non-HIV patients between 2009 and 2015. A total of 132 C. neoformans and C. gattii were subjected to antifungal susceptibility testing by E-test method. Among the 132 isolates, 42 C. neoformans and C. gattii were analyzed by mating type and URA5-RFLP. A total of 113 C. neoformans and C. gattii were subjected to multi-locus sequence typing (MLST). MLST results revealed that ST5 was the major molecular type. The wild-type (WT) phenotype was seen in 91.5-100% of C. neoformans isolates for amphotericin B, 5-flucytosine, fluconazole, and voriconazole. However, 72.3% (94/130) of C. neoformans isolates were non-wild-type (non-WT) to itraconazole by E-test method. In the sixth study year, the geometric mean, MIC50 and MIC90 of fluconazole were the highest (P  less then  0.001). Among 132 patients. 52 were coinfected with HIV and 80 were HIV-negative. Isolates from HIV and non-HIV patients showed no differences in susceptibility to amphotericin B (P = 0.544), 5-flucytosine (P = 0.063), fluconazole (P = 0.570), voriconazole (P = 0.542), and itraconazole (P = 0.787). Our study showed that Cryptococcus in southwest China showed a low degree of genetic diversity. The increased MIC values of fluconazole are noted. Cryptococcus isolates from HIV and non-HIV patients have shown no differences in susceptibility to five antifungal agents.

Dengue is the leading cause of mosquito-borne viral infection. It is responsible for high morbidity and mortality in children living in endemic areas. Nowadays, neurological complications are progressively referred to and include a broad spectrum of symptoms. It can be secondary to metabolic alterations, direct invasion by the virus, and enhanced autoimmune response.

Here, we report a rare case of hydrocephalus secondary to dengue encephalitis. A 13-day-old boy was diagnosed with dengue. He evolved with seizures and impaired consciousness being diagnosed with encephalitis. After clinical treatment, he was discharged fully recovered. Three months later, he presented with signs and symptoms of intracranial hypertension. Brain MRI revealed hydrocephalus secondary to acquired aqueduct stenosis. The patient underwent an endoscopic third ventriculocisternostomy.

Dengue infection is a differential diagnosis for acute febrile neurological impairment in children from endemic areas. Follow-up should be offered after dengue encephalitis to detect possible late-onset complications, as hydrocephalus.

Here, we collected cases of suicides among medical students enrolled at a local University in Italy and compared it to the general population of the same age group. Our sample was collected using records of suicides in the city of Pavia, Italy between the years of 2014 and 2019. This record was cross-referenced with enrolment numbers to the Medical Faculty of the city in order to select cases that involved medical students A time-window of 6 years was chosen for the evaluation. The odds ratio of suicide in medical students in comparison to the general population was of 14.58 (p value at the exact Poisson test less then 0.001). We then differentiated between native Italians and students from abroad. In this case, an odds ratio of 6.81 was observed (p value at the exact Poisson test 0.011). Our estimated suicide rates exceeded what was previously reported for the general population. We call for a closer attention on mental health in medical students, and an increased effort in collecting objective data on the topic.Gambling has had mixed reactions over the years as a positive economic activity and as a negative action that leads to addiction. The purpose of the study is to examine whether the level of income and nature of employment explain the actual instant gratification behavior among bettors in Uganda. This study adopted a cross-sectional quantitative research design. Data was collected from 257 bettors in 26 betting firms, and a census survey was found appropriate to achieve a response rate of 98%. The research findings indicate that low-income earners are more likely to engage in sports betting. Secondly, individuals with jobs where they have too much free time and inadequate supervision are most likely to participate in sports betting. We, therefore, recommend that both private and public organizations should be concerned about the impact of sports betting on their performance and employees. Most entities don't have gambling policies, and sports betting has a negative impact, for example, in terms of labor producowever, this might have limited the amount of information collected from the respondents. Therefore, future studies should employ other methods, such as an interview guide.Takotsubo cardiomyopathy (TCM) is characterized by temporary wall motion abnormality of the left ventricle. There is much debate upon the prognostic parameters. We conducted a systematic review and meta-analysis to investigate whether LVEF and the presence of apical ballooning predict long-term mortality in TCM. PubMed and Embase were searched through to October 30, 2017 without language restrictions, followed by an additional search through to February 2, 2020. Our search identified 18 studies that met the inclusion criteria, with a total of 5168 patients. Reduced LVEF as a categorical variable was associated with more than threefold increase in mortality risk in TCM patients (HR 3.10; 95% CI 1.78-5.42; P  less then  0.0001; I2 = 57%). Further subset analyses with the exclusion of studies consisting of patients with coronary artery disease revealed another significant relationship between LVEF and mortality (HR 3.13; 95% CI 1.392-7.031; P  less then  0.006; I2 = 58%). LVEF as a continuous variable was also found to be associated with increased mortality risk. However, this relationship only retained significance when computing odds ratios instead of hazard ratios (OR 0.95; 95% CI 0.93-0.98; P  less then  0.001; I2 = 0%). Finally, the existence of apical ballooning failed to demonstrate any link with an increased risk of mortality (HR 1.26; 95% CI 0.97-1.64; P = 0.09; I2 = 34%). LVEF and apical ballooning are both potential prognostic markers for mortality.The present paper displays new supramolecular structural forms of ammonia molecules. The computation reveals that two novel threading structures of C2F2·(NH3)6 and C2F2·(NH3)12 can be assembled between difluoroethyne and ammonia molecules, in which cyclohexamer (NH3)6 and dicyclohexamer (NH3)12 are constructed by robust N-H···N hydrogen bonds and stabilized all by π-ring-hole···N bonds as supporting spokes of annular structures. More interestingly, annular structures of NH3 still maintain stability as C2F2 is removed. Additionally, the electronic properties and nature of the related noncovalent bonds are explored, which illuminate the important role of π-ring-hole bond for the stabilization of annular structures of NH3. This study could provide valuable insights into chemistry of ammonia, new energy and astronomy aspects by single or multiple noncovalent interactions.Graphical abstract Ammonia molecules can exist stably in dodecahedral cage C2F2·(NH3)12 and (NH3)12 via N-H···N hydrogen bonds and π-ring-hole···N bonds.Rheumatology practice, during Coronavirus Disease 2019 (COVID-19) pandemic, has faced multifaceted challenges. Rheumatologists routinely prescribe immunosuppressant medications to their patients with multisystem autoimmune rheumatic diseases who are concerned about the increased risk of acquiring COVID-19 infection and are anxious to know if they should continue or hold these medications. Rheumatologists are often inundated by calls from their patients and physician colleagues caring for COVID-19 patients in hospitals, about how to manage the immunosuppression. Physicians face the challenging task of keeping up with the most up-to-date information on COVID-19. There are uncertainties about the mode of spread, clinical features, management options as well as long-term complications of COVID-19. Data are rapidly evolving and different studies on treatment options are showing contradictory results. click here It is known that viral illnesses can trigger a flare-up of underlying rheumatic disease that was previously in remission.
