Efficacy and safety of revisional treatments for weight regain or insufficient weight loss after Roux-en-Y gastric bypass: A systematic review and meta-analysis.

Weight regain or inadequate weight loss following Roux-en-Y gastric bypass poses a significant clinical challenge. Our objective was to evaluate various revisional techniques for addressing weight regain and insufficient weight loss after Roux-en-Y gastric bypass through a systematic review and meta-analysis. We performed a literature search (in PubMed and Embase) on revisional interventions in collaboration with a medical information specialist. Measured outcomes included body mass index at intervention, total weight loss during follow-up, and complications. Random effects models were used to determine pooled effect size and corresponding 95% confidence intervals. Thirty-nine studies were included: four studies reported on argon plasma coagulation, four studies on transoral outlet reduction, nine studies on transoral outlet reduction + argon plasma coagulation, four studies on pouch/gastrojejunal anastomosis revision, five on laparoscopic gastric banding, two studies on laparoscopic gastric banding + pouch resizing, 10 on distalization-RYGB, and one on duodenal switch. All techniques resulted in short-term clinically relevant weight loss. Endoscopic procedures had a short follow-up and resulted in modest and temporary weight loss. Surgical revision techniques were successful for weight loss in longer term follow-up, at the expense of high complication rates.

Similar Sensitivity of SARS-CoV-2 Detection in Oropharyngeal/Nasopharyngeal and Saliva Samples on the Hologic Panther Platform.

BACKGROUND: Oropharyngeal (OP) and nasopharyngeal (NP) sampling has historically been considered the reference specimen type used for respiratory virus detection. Saliva could be a less invasive alternative for SARS-CoV-2 detection, but limited evidence is available. METHODS: The technical and clinical performance of saliva was compared to OP/NP on the Hologic Panther platform with two Aptima assays, the End-Point Transcription-Mediated Amplification assay (EP-TMA) and Real-Time Transcription-Mediated Amplification assay (RT-TMA). The samples were collected at the Public Health Service Testing Site XL location in Schiphol Amsterdam Airport. At the site, the Regional Public Health Laboratory Kennemerland (RPHLK) has a fully equipped laboratory facility. RESULTS: A total of 374 samples (187 OP/NP swabs and 187 saliva samples) were collected from 187 unique patients. The Real-Time Transcription-Mediated Amplification assay (RT-TMA) resulted in comparable sensitivities for the detection of SARS-CoV-2 in both the OP/NP swabs (88.3%; 113/128) and saliva samples (87.5%; 112/128). The End-Point Transcription-Mediated Amplification assay (EP-TMA) analyses showed a similar sensitivity (86.7%; 111/128) in the OP/NP swabs but a lower sensitivity in the saliva samples (80.5%; 103/128). Within the discordant analyses, we found no associations in the symptoms, earlier SARS-CoV-2 infections and eating, smoking, drinking and tooth brushing habits within one hour before testing. CONCLUSIONS: The Hologic Panther platform Real-Time Transcription-Mediated Amplification assay (RT-TMA) yields a sensitivity for the detection of SARS-CoV-2 in saliva that is comparable to the OP/NP swabs derived from participants presenting themselves at a public health testing facility with minimal or mild symptoms.

The use of in-hospital medical care for patients with metastasized colon, bronchus, or lung cancer.

PURPOSE: At the end of life, patients and their families tend to favor adequate pain and symptom management and attention to comfort measures over prolongation of life. However, it has been suggested that many cancer patients without curative options still receive aggressive treatment. We therefore aimed to describe the number of diagnostic procedures, hospitalization, and medication use among these patients as well as factors associated with receiving such care. METHODS: We conducted a cohort study on all patients with metastasized cancer from a primary colon or bronchus and lung (BL) neoplasm from the moment of first admittance (January-December 2017) to end of follow-up (November 2018) or death. RESULTS: A total of 408 patients with colon (36%) or BL (64%) cancer were included in this study, with a median survival time of 7.4 months. 93% of the patients were subjected to at least one diagnostic procedure, 49% received chemotherapy, and 56% received expensive medication including immunotherapy. Patients had a median of 4.6 hospital admissions and 2.3 emergency room (ER) visits. A quarter of all patients (n = 105) received specialized palliative care with a mean of 1.96 consultations and the first consultation after a median time of 4.1 months. Patients with BL neoplasms received significantly more diagnostic procedures, chemotherapy episodes, ER/ICU admissions, and more often received an end-of-life statement per person-year than patients with a primary colon neoplasm. Females received significantly less diagnostic procedures and visited the ER/ICU less frequently than males, and patients aged > 70 years received significantly less chemotherapy (episodes) and expensive medication than younger patients. No differences in care were found between different socioeconomic status groups. CONCLUSION: Patients with metastasized colon or BL cancer receive a large amount of in-hospital medical care. Specialized palliative care was initiated relatively late despite the incurable disease status of all patients. Factors associated with more procedures were BL neoplasms, age between 50 and 70, and male gender.

Gender differences in retention rate of tumor necrosis factor alpha inhibitor treatment in ankylosing spondylitis: a retrospective cohort study in daily practice.

AIM: To assess gender differences in ankylosing spondylitis (AS) patients in relation to tumor necrosis factor alpha inhibitor (TNFi) drug survival and occurrence of adverse events in daily practice in a large peripheral hospital. METHOD: Retrospective data were collected from AS patients treated with etanercept, infliximab and adalimumab between January 2004 and January 2014. Kaplan-Meier survival curves were conducted to describe the drug survival and occurrence of adverse events in time. RESULTS: Overall, 122 AS patients (60.7% male) were included over a 10-year time period, with a mean treatment period of 51 months (1-127 months). In total, 21 (17.2%) patients stopped the TNFi, mainly due to inefficacy (52.4%). Female patients showed a significant shorter treatment period compared to males (33.4 vs. 44.9 months). In addition, female patients switched more between TNFi compared to males (26.9% vs. 16.3%) and had a significantly higher risk at developing infections compared to male patients (26% vs.19%). CONCLUSION: Females stayed on the same TNFi for a significantly shorter period compared to males (33.4 vs. 44.9 months) and the most important reason to stop or switch the drug was inefficacy. Moreover, females seemed to be more prone to infections during TNFi treatment than males.

Growth of Legionella anisa in a model drinking water system to evaluate different shower outlets and the impact of cast iron rust.

Legionella continues to be a problem in water systems. This study investigated the influence of different shower mixer faucets, and the influence of the presence of cast iron rust from a drinking water system on the growth of Legionella. The research is conducted using a model of a household containing four drinking water systems. All four systems, which contained standard plumbing components including copper pipes and a water heater, were filled with unchlorinated drinking water. Furthermore, all systems had three different shower faucets: (A) a stainless-steel faucet, (B) a brass-ceramic faucet, and (C) a brass thermostatic faucet. System 1 was solely filled with drinking water. System 2 was filled with drinking water, and cast iron rust. System 3 was contaminated with Legionella, and system 4 was contaminated with a Legionella, and cast iron rust. During a period of 34 months, 450 cold water samples were taken from 15 sample points of the four drinking water systems, and tested for Legionella according to the Dutch Standard (NEN 6265). In system 4, with added cast iron rust, the stainless-steel mixer faucet (A) had the highest concentration of Legionella at >4.3log10CFU/l (>20,000CFU/l) and was positive in 46.4% of samples. In contrast, the stainless-steel mixer faucet (A) of system 3 without cast iron rust showed 14.3% positive samples with a maximum concentration of 3.9log10CFU/l (7600CFU/l) Legionella. Additionally, both contaminated systems (3 and 4), with the brass thermostatic faucet (C), tested positive for Legionella. System 3 in 85.7% of the samples, with a maximum concentration of 4.38log10CFU/l (24,200CFU/l), and system 4 in 64.3% of the samples with a maximum concentration of 4.13log10CFU/l (13.400CFU/l). These results suggest that both the type of faucet used in a drinking water system and the presence or absence of cast iron rust influence the growth of Legionella.

Costs and Benefits Associated with the MRSA Search and Destroy Policy in a Hospital in the Region Kennemerland, The Netherlands.

OBJECTIVE: The objective of this study was to analyze the costs and benefits of the MRSA Search and Destroy (S&D) policy between 2008 and 2013 in the Kennemer Gasthuis, a 400 bed teaching hospital in the region Kennemerland, the Netherlands. METHODS: A patient registration database was used to retrospectively calculate costs, including screening, isolation, follow-up, contact tracing, cleaning, treatment, deployment of extra healthcare workers, salary for an infection control practitioner (ICP) and service of isolation rooms. The estimated benefits (costs and lives when no MRSA S&D was applied) were based on a varying MRSA prevalence rate (up to 50%). RESULTS: When no MRSA S&D policy was applied, the additional costs and deaths due to MRSA bacteraemia were estimated to be € 1,388,907 and 33 respectively (at a MRSA prevalence rate of 50%). Currently, the total costs were estimated to be € 290,672 (€ 48,445 annually) and a MRSA prevalence rate of 17.3% was considered as break-even point. Between 2008 and 2013, a total of 576 high risk patients were screened for MRSA carriage, of whom 19 (3.3%) were found to be MRSA positive. Forty-nine patients (72.1%) were found unexpectedly. CONCLUSIONS: Application of the MRSA S&D policy saves lives and money, although the high rate of unexpected MRSA cases is alarming.

Diagnosing perforated appendicitis in pediatric patients: a new model.

OBJECTIVE: Studies have investigated sensitivity and specificity of symptoms and tests for diagnosing appendicitis in children. Less is known with regard to the predictive value of these symptoms and tests with respect to the severity of appendicitis. The aim of this study was to determine the predictive value of patient's characteristics and tests for discriminating between perforated and nonperforated appendicitis in children. PATIENTS AND METHODS: Pediatric patients who underwent an appendectomy at Spaarne Hospital Hoofddorp, the Netherlands, between January 1, 2009 and December 31, 2013, were included. Baseline patient's characteristics, history, physical examination, laboratory data and results of ultrasounds were collected. Univariate and multivariate logistic regressions were used to determine predictors of perforation. RESULTS: In total, 375 patients were included in this study of which 97 children (25.9%) had significant signs of perforation. Univariate analysis showed that age, duration of complaints, temperature, vomiting, CRP, WBC, different findings on ultrasound and the diameter of the appendix were good predictors of a perforated appendicitis. The final multivariate prediction model included temperature, CRP, clearly visible appendix and free fluids on ultrasound and diameter of the appendix and resulted in an area under the curve (AUC) of 0.91 showing sensitivity and specificity of respectively 85.2% and 81.2%. CONCLUSION: This prediction model can be used for identification of 'high-risk' children for a perforated appendicitis and might be helpful to prevent complications and longer hospitalization by bringing these children to theater earlier.

Systemic markers of inflammation and cognitive decline in old age.

OBJECTIVES: To investigate whether higher circulating levels of C-reactive protein (CRP), interleukin-6 (IL-6), and alpha1-antichymotrypsin (ACT) are associated with worse cognitive function and decline in old age. DESIGN: Two independent population-based cohort studies. SETTING: The Rotterdam Study (mean follow-up 4.6 years) and the Leiden 85-plus Study (maximal follow-up 5 years). PARTICIPANTS: Three thousand eight hundred seventy-four individuals, mean age 72, from the Rotterdam Study, and 491 individuals, all aged 85, from the Leiden 85-plus Study. MEASUREMENTS: Both studies assessed global cognition, executive function, and memory. Linear regression analyses were used in the current study to investigate the associations between inflammatory markers and cognitive function and decline. RESULTS: In the Rotterdam Study, higher levels of CRP and IL-6 were cross-sectionally associated with worse global cognition and executive function (P<.05). ACT was not associated with cognitive function. In the Leiden 85-plus Study, estimates were similar for CRP, although not statistically significant. Higher IL-6 levels were related to a steeper annual decline in memory function in the longitudinal analysis in the Leiden 85-plus Study (P<.05). The effect of higher IL-6 levels on global and memory function decline was stronger in apolipoprotein E (APOE) epsilon4 carriers (P-interaction=.01) than in those who were not (P-interaction=.05). In the Rotterdam Study, higher IL-6 levels were related to a steeper annual decline in global cognition in APOE epsilon4 carriers only. CONCLUSION: Systemic markers of inflammation are only moderately associated with cognitive function and decline and tend to be stronger in carriers of the APOE epsilon4 allele. Systemic markers of inflammation are not suitable for risk stratification.
