      BACKGROUND: Potentially untreatable Plasmodium falciparum malaria threatens the Greater Mekong subregion. A previous series of pilot projects in Myanmar, Laos, Cambodia, and Vietnam suggested that mass drug administration was safe, and when added to provision of early diagnosis and treatment, could reduce the reservoir of P falciparum and interrupts transmission. We examined the effects of a scaled-up programme of this strategy in four townships of eastern Myanmar on the incidence of P ...

      BACKGROUND: Restorative anterior resection is considered the optimal procedure for most patients with rectal cancer and is frequently preceded by radiotherapy. Both surgery and preoperative radiotherapy impair bowel function, which adversely affects quality of life.

      OBJECTIVE: This study aimed to report symptoms associated with and key predictors for bowel-related quality-of-life impairment.

      DESIGN: The study included a cross-sectional cohort.

      SETTINGS: This was a multicenter study from ...

      BACKGROUND: An increasing number of patients are surviving a diagnosis of rectal cancer. The majority of the patients are treated with the sphincter-sparing surgical procedure low anterior resection, and 50% to 90% of these patients experience bowel dysfunction, known as the low anterior resection syndrome. No previous studies have investigated the association between the low anterior resection syndrome and quality of life in an international setting with the use of a validated ...

      Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome ...

      PurposeGeneral population reference data are useful in the interpretation of health-related quality of life (HRQoL) results, but for the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30), such data have been published for only seven countries. In 1992, Danish general population data were collected from women only for EORTC QLQ-C30 version 1. Since no Danish reference data exists for men and women for the QLQ-C30 version 3.0, the ...

      BACKGROUND: Otitis media is endemic in remote Indigenous communities of Australia's Northern Territory. Alloiococcus otitidis is an outer ear commensal and putative middle ear pathogen that has not previously been described in acute otitis media (AOM) in this population. The aims of this study were to determine the presence, antibiotic susceptibility and bacterial load of A. otitidis in nasopharyngeal and ear discharge swabs collected from Indigenous Australian children with AOM with ...

      PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway.

      PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer ...

      PURPOSE: This study was designed to evaluate possible social and geographic factors that could have an impact on quality of life in patients after abdominoperineal excision of the rectum. Although the number of patients with rectal cancer who need to be treated with abdominoperineal excision of the rectum and construction of permanent colostomy has greatly decreased in the past, there is still controversy about the influence on quality of life caused by this procedure.

      METHODS: In a ...

      PURPOSE: This study evaluated long-term results of transanal irrigation for defecation disturbances.

      METHODS: Three hundred and forty-eight patients [248 women and 100 men; median age 52 years (range, 5-85)] suffering from constipation and fecal incontinence were introduced to transanal irrigation. Patients using transanal irrigation at follow-up received a mailed questionnaire describing bowel function and practical procedures. Results from patients not responding and patients no longer ...

      OBJECTIVE: The aims of this study were to investigate the convergent and discriminative validity and reliability of the low anterior resection syndrome (LARS) score in an international setting.

      BACKGROUND: The LARS score is a simple self-administered questionnaire measuring bowel dysfunction after rectal cancer surgery. The score is intended to be commonly used in international research and clinical practice in the future. Therefore, a thorough validation in an international setting is ...

      OBJECTIVE: Bowel dysfunction is common following a restorative rectal cancer resection, but symptom severity and the degree of quality of life impairment is highly variable. An internationally validated patient-reported outcome measure, Low Anterior Resection Syndrome (LARS) score, now enables these symptoms to be measured. The study purpose was: (1) to develop a model that predicts postoperative bowel function; (2) externally validate the model and (3) incorporate these findings into a ...

      BACKGROUND: Surgical services are preparing to scale up in areas affected by COVID-19. This study aimed to evaluate the association between preoperative SARS-CoV-2 testing and postoperative pulmonary complications in patients undergoing elective cancer surgery.

      METHODS: This international cohort study included adult patients undergoing elective surgery for cancer in areas affected by SARS-CoV-2 up to 19 April 2020. Patients suspected of SARS-CoV-2 infection before operation were ...

      BACKGROUND: People suffering from neurogenic bowel dysfunction (NBD) and an ineffective bowel regimen often suffer from fecal incontinence (FI) and related symptoms, which have a huge impact on their quality of life. In these situations, transanal irrigation (TAI) has been shown to reduce these symptoms and improve quality of life.

      AIM: To investigate the long-term cost-effectiveness of initiating TAI in patients with NBD who have failed standard bowel care (SBC).

      METHODS: A ...

      BACKGROUND: The aims of this study were to provide data on the safety of head and neck cancer surgery currently being undertaken during the coronavirus disease 2019 (COVID-19) pandemic.

      METHODS: This international, observational cohort study comprised 1137 consecutive patients with head and neck cancer undergoing primary surgery with curative intent in 26 countries. Factors associated with severe pulmonary complications in COVID-19-positive patients and infections in the surgical team ...

      BACKGROUND: Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction.

      METHODS: This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a ...
