Unsupervised Feature Extraction From Raw Data for Gesture Recognition With Wearable Ultralow-Power Ultrasound.

Wearable ultrasound (US) is a novel sensing approach that shows promise in multiple application domains, and specifically in hand gesture recognition (HGR). In fact, US enables to collect information from deep musculoskeletal structures at high spatiotemporal resolution and high signal-to-noise ratio, making it a perfect candidate to complement surface electromyography for improved accuracy performance and on-the-edge classification. However, existing wearable solutions for US-based gesture recognition are not sufficiently low power for continuous, long-term operation.

Effects of thiazides and new findings on kidney stones and dysglycemic side effects.

Thiazide and thiazide-like diuretics (thiazides) belong to the most frequently prescribed drugs worldwide. By virtue of their natriuretic and vasodilating properties, thiazides effectively lower blood pressure and prevent adverse cardiovascular outcomes. In addition, through their unique characteristic of reducing urine calcium, thiazides are also widely employed for the prevention of kidney stone recurrence and reduction of bone fracture risk.

F-FDG-PET/CT to Detect Pathological Complete Response After Neoadjuvant Treatment in Patients with Cancer of the Esophagus or Gastroesophageal Junction: Accuracy and Long-Term Implications.

Purpose: The curative strategy for patients with esophageal cancer without distant metastases consists of esophagectomy with preceding chemo(radio)therapy (CRT). In 10-40% of patients treated with CRT, no viable tumor is detectable in the resection specimen (pathological complete response (pCR)). This study aims to define the clinical outcomes of patients with a pCR and to assess the accuracy of post-CRT FDG-PET/CT in the detection of a pCR.

Thiazides Attenuate Insulin Secretion Through Inhibition of Mitochondrial Carbonic Anhydrase 5b in β -Islet Cells in Mice.

Significance Statement: Thiazide diuretics (thiazides) are among the most widely prescribed drugs worldwide, but their use is associated with glucose intolerance and new-onset diabetes mellitus. The molecular mechanisms remain elusive. Our study reveals that thiazides attenuate insulin secretion through inhibition of the mitochondrial carbonic anhydrase isoform 5b (CA5b) in pancreatic β cells.

The role of urinary supersaturations for lithogenic salts in the progression of autosomal dominant polycystic kidney disease.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is associated with significant risk of forming kidney stones, especially those made of calcium oxalate and uric acid, compared with the general population. Since crystals are able to activate the inflammasome and lead to cell injury, crystalluria might worsen ADPKD natural history, acting as a third hit.

Methods: The Bern ADPKD registry is a prospective observational cohort study.

Tolvaptan treatment is associated with altered mineral metabolism parameters and increased bone mineral density in ADPKD patients.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is characterized by a unique bone and mineral phenotype. The impact of tolvaptan treatment on mineral metabolism and bone mineral density (BMD) is unknown.

Methods: We conducted an analysis in the Bern ADPKD Registry, a prospective observational cohort study.

The Less Well-Known Little Brothers: The SLC9B/NHA Sodium Proton Exchanger Subfamily-Structure, Function, Regulation and Potential Drug-Target Approaches.

The SLC9 gene family encodes Na/H exchangers (NHEs), a group of membrane transport proteins critically involved in the regulation of cytoplasmic and organellar pH, cell volume, as well as systemic acid-base and volume homeostasis. NHEs of the SLC9A subfamily (NHE 1-9) are well-known for their roles in human physiology and disease. Much less is known about the two members of the SLC9B subfamily, NHA1 and NHA2, which share higher similarity to prokaryotic NHEs than the SLC9A paralogs.

Humoral and cellular immune responses on SARS-CoV-2 vaccines in patients with anti-CD20 therapies: a systematic review and meta-analysis of 1342 patients.

Background: Immune responses on SARS-CoV-2 vaccination in patients receiving anti-CD20 therapies are impaired but vary considerably. We conducted a systematic review and meta-analysis of the literature on SARS-CoV-2 vaccine induced humoral and cell-mediated immune response in patients previously treated with anti-CD20 antibodies.

Methods: We searched PubMed, Embase, Medrxiv and SSRN using variations of search terms 'anti-CD20', 'vaccine' and 'COVID' and included original studies up to 21 August 2021.

Deletion of the sodium/hydrogen exchanger 6 causes low bone volume in adult mice.

The sodium/hydrogen exchanger 6 (NHE6) localizes to recycling endosomes, where it mediates endosomal alkalinization through K/H exchange. Mutations in the SLC9A6 gene encoding NHE6 cause severe X-linked mental retardation, epilepsy, autism and corticobasal degeneration in humans. Patients with SLC9A6 mutations exhibit skeletal malformations, and a previous study suggested a key role of NHE6 in osteoblast-mediated mineralization.

Risk Factors and Consequences of Anastomotic Leakage After Esophagectomy for Cancer.

Background: Identifying predictors of anastomotic leakage can contribute to prevention of this common complication after esophagectomy. This study identified predictors for anastomotic leakage and assessed the influence of anastomotic leakage on short-term outcomes and long-term survival.

Methods: A retrospective cohort study was conducted of consecutive patients who underwent esophagectomy in the Amsterdam University Medical Centers, location Amsterdam Medical Center, between 1993 and 2019.

Quality of Life in Autosomal Dominant Polycystic Kidney Disease Patients Treated With Tolvaptan.

Rationale & Objective: The impact of tolvaptan on health-related quality-of-life (HRQoL) in patients with autosomal dominant polycystic kidney disease (ADPKD) is unknown. To address this knowledge gap, we studied patient-reported HRQoL in patients enrolled in the Bern ADPKD registry.

Study Design: Prospective cohort study.

The sodium/proton exchanger NHA2 regulates blood pressure through a WNK4-NCC dependent pathway in the kidney.

NHA2 is a sodium/proton exchanger associated with arterial hypertension in humans, but the role of NHA2 in kidney function and blood pressure homeostasis is currently unknown. Here we show that NHA2 localizes almost exclusively to distal convoluted tubules in the kidney. NHA2 knock-out mice displayed reduced blood pressure, normocalcemic hypocalciuria and an attenuated response to the thiazide diuretic hydrochlorothiazide.

Learning inguinal hernia repair? A survey of current practice and of preferred methods of surgical residents.

Purpose: During surgical residency, many learning methods are available to learn an inguinal hernia repair (IHR). This study aimed to investigate which learning methods are most commonly used and which are perceived as most important by surgical residents for open and endoscopic IHR.

Methods: European general surgery residents were invited to participate in a 9-item web-based survey that inquired which of the learning methods were used (checking one or more of 13 options) and what their perceived importance was on a 5-point Likert scale (1 = completely not important to 5 = very important).

Urinary Lithogenic Risk Profile in ADPKD Patients Treated with Tolvaptan.

Background And Objectives: Nephrolithiasis is a common health problem in autosomal dominant polycystic kidney disease (ADPKD) and significantly contributes to patient morbidity. Recently, Tolvaptan has been introduced for the treatment of ADPKD, but whether it is associated with alterations of the urinary lithogenic risk profile remains unknown.

Design, Setting, Participants, & Measurements: We conducted an analysis of participants enrolled in the Bern ADPKD registry, a prospective observational cohort study.

Feasibility of extended chemoradiotherapy plus surgery for patients with cT4b esophageal carcinoma.

Background: Treatment of cT4b esophageal carcinoma usually consists of definitive chemoradiotherapy (dCRT). However, outcome after dCRT in these patients is poor. Whether surgery should have a place in the treatment of cT4b esophageal cancer is still subject to debate.

Would it be safe to have a dog in the MRI scanner before your own examination? A multicenter study to establish hygiene facts related to dogs and men.

Objectives: To determine whether it would be hygienic to evaluate dogs and humans in the same MRI scanner.

Methods: We compared the bacterial load in colony-forming units (CFU) of human-pathogenic microorganisms in specimens taken from 18 men and 30 dogs. In addition, we compared the extent of bacterial contamination of an MRI scanner shared by dogs and humans with two other MRI scanners used exclusively by humans.

International Survey on the Management of Anastomotic Leakage After Esophageal Resection.

Background: Anastomotic leakage is one of the most severe complications following esophageal surgery, leading to significant morbidity, prolonged hospital stay, considerable costs, decreased quality of life, and increased mortality. Management of anastomotic leakage is complicated and has currently not been standardized. The objective of this research is to gain insight into the different opinions on anastomotic leakage management among upper gastrointestinal surgeons and verify the need for diagnostic and treatment guidelines.

Lymph node metastases near the celiac trunk should be considered separately from other nodal metastases in patients with cancer of the esophagus or gastroesophageal junction after neoadjuvant treatment and surgery.

Background: The aim of the present study is to identify the incidence and prognostic significance of lymph node metastases near the celiac trunk in patients who underwent neoadjuvant chemo(radio)therapy followed by esophagectomy.

Methods: Between March 1994 and September 2013 a total of 462 consecutive patients with cancer of the esophagus or gastroesophageal junction (GEJ) who underwent potentially curative esophageal resection after neoadjuvant chemotherapy (N=88; 19.0%) or neoadjuvant chemoradiotherapy (CRT) (N=374; 81.

Elevated FGF23 Levels in Mice Lacking the Thiazide-Sensitive NaCl cotransporter (NCC).

Fibroblast growth factor 23 (FGF23) participates in the orchestration of mineral metabolism by inducing phosphaturia and decreasing the production of 1,25(OH)D. It is known that FGF23 release is stimulated by aldosterone and extracellular volume depletion. To characterize this effect further in a model of mild hypovolemia, we studied mice lacking the thiazide sensitive NaCl cotransporter (NCC).
