In addition, anticancer effects of SCFAs have proved in the colorectal cancer. In this review, we discuss microbial dysbiosis and its impact on chemotherapy- or radiation-induced intestinal mucositis. Moreover, we summarize the mechanisms of SCFA production and its effects on intestinal mucositis. This review suggests the therapeutic potential of SCFAs for the management of chemotherapy- or radiation-induced intestinal inflammation.

Geriatric patients with a fragility fracture of the hip (FFH) are especially prone to sarcopenia with poor functional outcomes and quality of life. We assessed the prevalence of sarcopenia in older South African patients with FFH. Risk factors for sarcopenia were also investigated.

From August 1 to November 30, 2018, all older patients with FFH were invited to participate. Sarcopenia was diagnosed based on the revised criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). Handgrip strength (HGS) and muscle strength were assessed. Muscle quantity was determined by dual-energy X-ray absorptiometry. Demographic information was collected, and 25-hydroxyvitamin D (25[OH]D) status was determined.

Of the 100 hip fracture cases, 65 were enrolled, and 52% (34/65) were sarcopenic (women 62%; men 38%). HGS accurately identified sarcopenia (sensitivity and specificity 100%). Patients >80 years of age had a prevalence of sarcopenia twice (18/21 [83%]) that of younger patients (18/44 [36%]lence of sarcopenia in our FFH population is high. Sarcopenia is associated with poor patient outcomes following surgical intervention. Orthopaedic surgeons should therefore be cognizant of the presentation and associated risk of sarcopenia as our patient populations age.The WHO declared the coronavirus disease 2019 (COVID-19) outbreak as a public health emergency of international concern on January 30, 2020, and then a pandemic on March 11, 2020. COVID-19 affected over 200 countries and territories worldwide, with 25,541,380 confirmed cases and 852,000 deaths associated with COVID-19 globally, as of September 1, 2020.1 While facing such a public health emergency, hospitals were on the front line to deliver health care and psychological services. Tovorafenib The early detection, diagnosis, reporting, isolation, and clinical management of patients during a public health emergency required the extensive involvement of hospitals in all aspects. The response capacity of hospitals directly determined the outcomes of the prevention and control of an outbreak. The COVID-19 pandemic has affected almost all nations and territories regardless of their development level or geographic location, although suitable risk mitigation measures differ between developing and developed countries. In low- and middle-income countries (LMICs), the consequences of the pandemic could be more complicated because incidence and mortality might be associated more with a fragile health care system and shortage of related resources.2, 3 As evidenced by the situation in Bangladesh, India, Kenya, South Africa, and other LMICs, socioeconomic status (SES) disparity was a major factor in the spread of disease, potentially leading to alarmingly insufficient preparedness and responses in dealing with the COVID-19 pandemic.4 Conversely, the pandemic might also bring more unpredictable socioeconomic and long-term impacts in LMICs, and those with lower SES fare worse in these situations. This review aimed to summarize the responsibilities of and measures taken by hospitals in combatting the COVID-19 outbreak. Our findings are hoped to provide experiences, as well as lessons and potential implications for LMICs.

The outbreak and global pandemic of coronavirus disease 2019 (COVID-19) attracts a great deal of attentions to the problem of travel health. Cruise tourism is increasingly popular, with an estimated 30 million passengers transported on cruise ships worldwide each year. Safeguarding the health of cruise travelers during the entire travel is of ultimate importance for both the industry and global public health.

This study aimed to explore the challenges and opportunities in travel health from the perspective of global health governance.

The global governance framework including problems, values, tools or regulations, and actors related to travel health were used to analyze the issues involved.

Up to April 2020, nearly thirty cruise ship voyages reported COVID-19 cases. The Diamond Princess, Grand Princess and Ruby Princess cruise ship had over 1,400 total reported COVID-19 cases, and more than 30 deaths. A community with a common future in travel health is the core value of global health governance for egislation at global and country level are required to prevent large-scale humanitarian crisis on travel health. Multilateral coordination, cooperation and collaboration mechanisms between governments, intergovernmental organizations, non-governmental organizations and industry are needed to build a better community of common destiny for travel health.Wastewater is a breeding ground for many pathogens, which may pose a threat to human health through various water transmission pathways. Therefore, a simple and effective method is urgently required to monitor and treat wastewater. As bacterial viruses, bacteriophages (phages) are the most widely distributed and abundant organisms in the biosphere. Owing to their capacity to specifically infect bacterial hosts, they have recently been used as novel tools in water pollution control. The purpose of this review is to summarize and evaluate the roles of phages in monitoring pathogens, tracking pollution sources, treating pathogenic bacteria, infecting bloom-forming cyanobacteria, and controlling bulking sludge and biofilm pollution in wastewater treatment systems. We also discuss the limitations of phage usage in water pollution control, including phage-mediated horizontal gene transfer, the evolution of bacterial resistance, and phage concentration decrease. This review provides an integrated outlook on the use of phages in water pollution control.We report a case of small bowel obstruction due to gallstone ileus found in a patient with previous pancreaticoduodenectomy (Whipple procedure). Investigation by computed tomography of the abdomen showed a transition point in the midjejunum due to a radioopaque intraluminal mass. Following resuscitation, the patient underwent laparotomy to remove the offending mass from the midjejunum. Subsequent stone analysis confirmed a cholesterol-rich gallstone. This is thus the first description of gallstone ileus following Whipple procedure. The rarity of this presentation and a literature review is presented.
