Retrorectal cystic hamartomas or tailgut cysts are infrequent congenital lesions presenting as presacral masses originating from the embryonic hindgut. They are commonly diagnosed in middle-aged women. Physicians must have a high index of suspicion to diagnose this rare tumor. We report a case of retrorectal hamartoma in a 70-year-old male presenting as rectal bleeding instead of the usual compressive symptoms. ABT-199 price The utility of imaging modalities and the paramount importance of histopathology has been described. The treatment modality is surgical excision to prevent the potential malignant transformation.Neuroendocrine tumors (NETs) are rare tumors derived from the neuroendocrine cell system, and more commonly found in the gastrointestinal (GI) tract. Over the last decades, the incidence of GI-NETs has been steadily increasing, partly due to the expanding indications for endoscopy. Most patients with NETs are asymptomatic, and their NETs are noticed during screening examinations; thus, endoscopists are on the frontline of the diagnosis of GI-NETs. Since GI-NETs are less frequent than other malignancies, the natural history, diagnosis, and management of these tumors may not be fully understood. In this review, we aim to update the endoscopist on key clinical features and management of patients with gastric, duodenal, and rectal NETs.

Hyperplastic polyps represent 30-93% of all gastric epithelial polyps. They are generally detected as innocuous incidental findings; however, they have a risk of neoplastic transformation and recurrence. Frequency and risk factors for neoplastic transformation and recurrence are not well established and are fields of ongoing interest. This study aims to evaluate the frequency of and identify the risk factors for recurrence and neoplastic change of gastric hyperplastic polyps (GHP).

A single-centre retrospective cohort study including consecutive patients who underwent endoscopic resection of GHP from January 2009 to June 2020. Demographic, endoscopic, and histopathologic data was retrieved from the electronic medical records.

A total of 195 patients were included (56% women; median age 67 [35-87] years). The median size of GHP was 10 (3-50) mm, 62% (

= 120) were sessile, 61% (

= 119) were located in the antrum, and 36% (

= 71) had synchronous lesions. Recurrence rate after endoscopic resection wascurrence and neoplastic transformation of GHP. Antrum location was a predictor of recurrence. The risk of neoplastic change was increased in large lesions and with intestinal metaplasia and dysplasia in adjacent mucosa. More frequent endoscopic surveillance may be required in these subgroups of GHP.

Endoscopic submucosal dissection (ESD) is a well-established endoscopic technique for the treatment of gastrointestinal lesions. Colorectal ESD outcomes are less reported in the Western literature, and Portuguese data are still very scarce. Our aim was to describe our experience on colorectal ESD regarding its outcomes and safety profile.

We conducted a retrospective evaluation of recorded data on ESDs performed between 2015 and 2020. Only ESDs performed on epithelial neoplastic lesions were selected for further analysis.

Of a total of 167 colorectal ESDs, 153 were included. Technical success was achieved in 147 procedures (96%). The lesions were located in the colon (

= 24) and rectum (

= 123). The en bloc resection rate was 92% and 97%, the R0 resection rate was 83% and 82%, and the curative resection rate was 79% and 78% for the colon and the rectum, respectively. The need for a hybrid technique was the only risk factor for piecemeal or R1 resection. We report a perforation rate of 3.4% and a 4.1% rate of delayed bleeding; all the adverse events were manageable endoscopically, without the need of blood transfusions or surgery. Most of the lesions were laterally spreading tumours of the granular mixed type (70%), and 20% of the lesions were malignant (12% submucosal and 8% intramucosal cancer).

Our series on colorectal ESD reports a very good efficacy and safety profile. This technique can be applied by endoscopists experienced in ESD.

Colorectal cancer (CRC) is one of the most common cancers in Europe. Recently, new data from the USA and Europe revealed an increase in the incidence of CRC in individuals aged <55 years and a reduction in those aged >65 years. Mortality rate was stable in patients aged <55 years and decreased after the age of 55 years. Based on the USA data, the American Cancer Society (ACS) published a qualified recommendation advocating the start of CRC screening at the age of 45 years. We aimed to evaluate if the changes in the CRC incidence/mortality observed in the USA and the rest of Europe also occur in Portugal, and then perform a cost-utility analysis of CRC screening that starts at 45 years of age.

We evaluated the incidence of CRC by age group using data from the National Cancer Registry, and the mortality rate according to the National Statistics Institute in the periods 1993-2010 and 2003-2016. A cost-utility analysis was performed with a decision tree from a societal perspective comparing biennial e rises above 47.5/100,000; colonoscopy at this age would have no cost utility despite changes in costs and/or incidence rates.

In Portugal, the incidence of CRC in patients aged 45-55 years has been increasing with a stable mortality rate, in contrast to the decrease in mortality in the age groups covered by the current CRC screening program. However, at present, CRC screening in Portugal at the age of 45 years has no cost utility and will only have this if the incidence rate rises above 47.5/100,000 (vs. the actual incidence of 30/100,000).

Midwives and nurses are critical in nutrition care for pregnant women and lactating mothers. Ghanaian nurses and midwives' perception of the adequacy and their satisfaction with nutrition education received during training in school, level of nutrition care competencies, and nutrition practice behavior is unknown. We evaluated the adequacy of nutrition education received in nursing and midwifery school; nutrition care competencies; self-efficacy and the nutrition care practice of midwives and nurses. We also evaluated determinants of nutrition care practice during routine antenatal and postnatal care. Methods. Cross-sectional study conducted among midwives and nurses working at antenatal and postnatal clinics in Ghana. Data was collected using a self-administered questionnaire. Data analysis was done using descriptive statistics, correlation, and linear regression. Findings. Almost 90% (n = 267) of the participants received nutrition education during training, 77.5% were unsatisfied with the amount of time allocated for nutrition education and 40% felt inadequately prepared from school to provide nutrition care. Self-efficacy ranged from moderate to low. Determinants of nutrition care practice were age of respondents (B = 0.04; P = .002), nutrition-related knowledge (B = 0.05; P = .016), adequacy of nutrition education (B = 0.14; P = .006), nutrition training after school (B = 0.38; P = .010) and nutrition care self-efficacy (B = 0.03; P = .048). Conclusion. Notable knowledge gaps in basic nutrition, inadequate preparedness, and poor confidence to provide nutrition care was common. There is a need to improve the nutrition education experiences of midwives and nurses through curricula revision and refresher training courses.An individual's outlook on society can change over time and can be related to both their physical and mental health. Here, we developed an instrument to measure outlooks on the past and future in relation to the present in 413 adults ranging in age from 18 to 80 years. Exploratory and confirmatory factor analyses were conducted on independent samples and test-retest reliability was assessed in a subset of participants. Construct validity of the two past and future scales was assessed by relating them to 1) pre-existing scales measuring related constructs, and 2) beliefs and safety behaviors during the COVID-19 pandemic. The final Bright or Bleak Scale (BOBS) consists of a past and future scale, each with two factors measuring societal and personal outlooks. Brighter future societal and personal outlooks were positively associated with longer future time perspectives, while self-reporting a higher likelihood of already having contracted COVID-19 was related to bleaker past societal and personal outlooks.Dysphagia is a common and frequently undetected complication of many neurological disorders and of sarcopoenia in ageing persons. Spontaneous swallowing frequency (SSF) has been mooted as a possible tool to classify dysphagia risk. We conducted a review of the literature to describe SSF in both the healthy population and in disease-specific populations, in order to consider its utility as a screening tool to identify dysphagia. We searched Medline, Embase, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials databases. Metadata were extracted, collated and analysed to give quantitative insight. Three hundred and twelve articles were retrieved, with 19 meeting inclusion and quality criteria. Heterogeneity between studies was high (I2 = 99%). Mean SSF in healthy younger sub-groups was 0.98/min [CI 0.67; 1.42]. In the Parkinson's sub-group, mean SSF was 0.59/min [0.40; 0.87]. Mean SSF in healthy older, higher risk and dysphagic populations were similar (0.21/min [0.09; 0.52], 0.26/min [0.10; 0.72] and 0.30/min [0.16; 0.54], respectively). SSF is a novel, non-invasive clinical variable which warrants further exploration as to its potential to identify persons at risk of dysphagia. Larger, well-conducted studies are needed to develop objective, standardised methods for detecting SSF, and develop normative values in healthy populations.Biolayer interferometry (BLI) is an emerging analytical tool that allows the study of protein complexes in real time to determine protein complex kinetic parameters. This article describes a protocol to determine the KD of a protein complex using a 6×His tagged fusion protein as bait immobilized on the NTA sensor chip of the FortéBio® Octet K2 System (Sartorius). We also describe how to determine the half maximal effective concentration (EC50, also known as IC50 for inhibiting effectors) of a metabolite. The complete protocol allows the determination of protein complex KD and small molecular effector EC50 within 8 h, measured in triplicates.
