A Rocking-chair Rechargeable Seawater Battery.

Seawater batteries are attracting continuous attention because seawater as an electrolyte is inexhaustible, eco-friendly, and free of charge. However, the rechargeable seawater batteries developed nowadays show poor reversibility and short cycle life, due to the very limited electrode materials and complicated yet inappropriate working mechanism. Here, we propose a rechargeable seawater battery that works through a rocking-chair mechanism encountered in commercial lithium ion batteries, enabled by intercalation-type inorganic electrode materials of open-framework-type cathode and Na-ion conducting membrane-type anode.

Increased age and the volume of intraoperative fluid administered predict urinary retention after elective inguinal herniorrhaphy.

Background: Inguinal hernia repair (IHR) is a common surgical procedure worldwide. Although IHR can be performed by the minimally invasive method, which accelerates recovery, postoperative urinary retention (POUR) remains a common complication that significantly impacts patients. Thus, it is essential to identify the risk factors associated with POUR to diminish its negative impact.

Perioperative Glutamine Supplementation May Restore Atrophy of Psoas Muscles in Gastric Adenocarcinoma Patients Undergoing Gastrectomy.

Background: Sarcopenia, characterized by degenerative skeletal muscle loss, is increasingly linked to poor surgical outcomes. Glutamine, an immune-modulating formula, may stimulate muscle protein synthesis and inhibit degradation. We used the psoas major muscle area (PMMA) at the third lumbar vertebra, normalized for height (PMMA index), as a skeletal muscle indicator.

Intravenous calcitriol administration improves the liver redox status and attenuates ferroptosis in mice with high-fat diet-induced obesity complicated with sepsis.

Obesity aggravates ferroptosis, and vitamin D (VD) may inhibit ferroptosis. We hypothesized that weight reduction and/or calcitriol administration have benefits against the sepsis-induced liver redox imbalance and ferroptosis in obese mice. Mice were fed a high-fat diet for 11 weeks, then half of the mice continued to consume the diet, while the other half were transferred to a low-energy diet for 5 weeks.

A Membrane-Free Rechargeable Seawater Battery Unlocked by Lattice Engineering.

Seawater batteries that directly utilize natural seawater as electrolytes are ideal sustainable aqueous devices with high safety, exceedingly low cost, and environmental friendliness. However, the present seawater batteries are either primary batteries or rechargeable half-seawater/half-nonaqueous batteries because of the lack of suitable anode working in seawater. Here, a unique lattice engineering to unlock the electrochemically inert anatase TiO anode to be highly active for the reversible uptake of multiple cations (Na, Mg, and Ca) in aqueous electrolytes is demonstrated.

Impact of preoperative factors and waiting time on post-appendectomy complications: a retrospective study.

Background: Several factors are associated with increased postoperative complications after appendectomies. However, few studies combined these potential factors for comprehensive prediction of surgical outcomes. Whether high-risk patients benefit from a shorter waiting time for surgery remains unclear.

A HO Oxidation Approach to TiC/TiO for Efficient Photocatalytic Removal of Distinct Organic Pollutants in Water.

To develop versatile photocatalysts for efficient degradation of distinct organic pollutants in water is a continuous pursuit in environment remediation. Herein, we directly oxidize TiC MXene with hydrogen peroxide to produce C-doped anatase TiO nanowires with aggregates maintaining a layered architecture of the MXene. The TiC MXene provides a titanium source for TiO, a carbon source for in situ C-doping, and templates for nanowire aggregates.

Placement of Nasogastric Tubes in Pancreaticoduodenectomy Patients: Switching from Immediate Intraoperative Removal to Avoiding Unnecessary Perioperative Use.

Background: The placement of nasogastric tubes (NGTs) in abdominal surgery has been adopted for decades to attenuate ileus and prevent aspiration pneumonia. In the recent era, the guidelines recommend not using NGT routinely, and even in pancreaticoduodenectomy (PD), immediate removal of NGT in operating rooms (ORs) was suggested. However, the clinical outcome and safety of abandoning NGT during the pre-PD and intra-PD periods remain unknown.

Calcitriol attenuates poly(I:C)-induced lung injury in obese mice via modulating toll-like receptor 3- and renin-angiotensin system-associated signal pathways.

This study investigated the effects of calcitriol on polyinosinic-polycytidylic acid (poly(I:C))-induced acute lung injury (ALI) and its association with Toll-like receptor 3 (TLR3) and renin-angiotensin system (RAS) signal pathways in obese mice. Normal mice were fed a high-fat diet to induce obesity. Obese mice were divided into four groups: SS group, intratracheally instilled with saline and intravenous (IV) saline injection via tail vein; SD group, instilled with saline and IV calcitriol injection; PS group, instilled with poly(I:C) and IV saline injection; and PD group, instilled with poly(I:C) and IV calcitriol injection.

Potential therapeutic implications of calcitriol administration and weight reduction on CD4 T cell dysregulation and renin angiotensin system-associated acute lung injury in septic obese mice.

This study investigated the effects of weight reduction and/or calcitriol administration on regulating CD4 T cell subsets and renin-angiotensin system (RAS)-associated acute lung injury (ALI) in obese mice with sepsis. Half of the mice were fed a high-fat diet for 16 weeks, half of them had high-fat diet for 12 weeks then were transferred to a low-energy diet for 4 weeks. After feeding the respective diets, cecal ligation and puncture (CLP) were performed to induce sepsis.

Novel Non-duct-to-Mucosa Pancreaticojejunostomy Reconstruction After Pancreaticoduodenectomy: Focus on the Occurrence of Post-pancreatectomy Hemorrhage and Intra-abdominal Abscess.

Background: Postoperative pancreatic fistulas (POPFs) are considered inevitable in some patients after pancreaticoduodenectomy (PD), and measures to minimize their clinical impact are needed. Postpancreatectomy hemorrhage (PPH) and intra-abdominal abscess (IAA) are the most severe POPF-related complications, and concomitant leakage of contaminated intestinal content is considered the main cause. An innovative method, modified non-duct-to-mucosa pancreaticojejunostomy (TPJ), was created to prevent concomitant leakage of intestinal content, and its effectiveness was compared between two periods.

Glutamine and leucine administration attenuates muscle atrophy in sepsis.

Aims: This study investigated whether l-glutamine (Gln) and/or l-leucine (Leu) administration could attenuate muscle atrophy in a mouse model of cecal ligation and puncture (CLP)-induced sepsis.

Materials And Methods: Septic mice were given a daily intraperitoneal injection of Gln, Leu, or Gln plus Leu, and mice were sacrificed on either day 1 or 4 after CLP. Blood and muscles were collected for analysis of amino acid contents and markers related to protein degradation, muscle regeneration, and protein synthesis.

Effects of different routes and forms of vitamin D administration on CD4 T cell homeostasis and renin-angiotensin system-associated lung injury in obese mice complicated with polymicrobial sepsis.

This study investigated the impacts of enteral cholecalciferol and/or intravenous calcitriol administration on the balance of cluster of differentiation 4-positive T cell subsets, the renin-angiotensin system (RAS), and the severity of acute lung injury (ALI) in obese mice with sepsis. Mice were fed a high-fat diet and then cecal ligation and puncture (CLP) was performed. Obese mice were divided into four sepsis groups: without vitamin D (VD) (S), with oral cholecalciferol 1 d before CLP (G), with intravenous calcitriol 1 h after CLP (V), and with both cholecalciferol before and intravenous calcitriol after CLP (GV).

Effects of Different Routes and Forms of Vitamin D Administration on Mesenteric Lymph Node CD4+ T Cell Polarization and Intestinal Injury in Obese Mice Complicated with Polymicrobial Sepsis.

This study compared the efficacies of enteral cholecalciferol and/or intravenous (IV) calcitriol administration on mesenteric lymph node (MLN) cluster-of-differentiation-4-positive (CD4+) T cell distribution and intestinal barrier damage in obese mice complicated with sepsis. Mice were fed a high-fat diet for 16 weeks and then sepsis was induced by cecal ligation and puncture (CLP). Mice were divided into the following sepsis groups: without vitamin D (VD) (S); with oral cholecalciferol 1 day before CLP (G); with IV calcitriol 1 h after CLP (V); and with both cholecalciferol before and IV calcitriol after CLP (GV).

Coronavirus Disease Pandemic Effect on Medical-Seeking Behaviors Even in One Resource-Competent Community: A Case Controlled Study.

(1) Background: The coronavirus disease 2019 (COVID-19) pandemic had overwhelming impacts on medical services. During its initial surge, Taiwan was unique in maintaining its medical services without imposing travel restrictions, which provided an ideal environment in which to test if the fear of becoming infected with COVID-19 interfered with health-seeking behavior (HSB). We tested this hypothesis among adults with acute complicated appendicitis (ACA).

Intravenous calcitriol treatment benefits the homeostasis of CD4 T cells and attenuates kidney injury in obese mice complicated with polymicrobial sepsis.

Objectives: Sepsis is a lethal clinical condition with dysregulated cluster of differentiation (CD) 4 T cells that leads to inflammation and multiorgan injury. Low vitamin D levels are commonly seen in patients with sepsis. Obesity is a state with oxidative stress and chronic inflammation.

Chemical composition of smoke produced by open versus laparoscopic surgery for cholecystectomy.

Background: Smoke produced by traditional open surgery (TOS) has long been considered hazardous to medical staff. Compared with TOS, minimally invasive surgery under carbon dioxide pneumoperitoneum is associated with a faster recovery and less wound pain. However, the impact of oxygen-deficient environment on the chemical contents of smoke has not been comprehensively assessed.

Association Between Neutrophil-to-Lymphocyte Ratio with Inflammatory Activity and Fibrosis in Non-alcoholic Fatty Liver Disease.

Background: Inflammation plays an important role in the development and progression of non-alcoholic steatohepatitis (NASH), and NASH is a powerful driving force for the progression of fibrosis. The neutrophil-to-lymphocyte ratio (NLR) is a simple emerging indicator of inflammation. We aimed to assess the potential association between NLR and histological severity of non-alcoholic fatty liver disease (NAFLD).

Protective Effects of Glutamine and Leucine Supplementation on Sepsis-Induced Skeletal Muscle Injuries.

This study investigated the effects of l-glutamine (Gln) and/or l-leucine (Leu) administration on sepsis-induced skeletal muscle injuries. C57BL/6J mice were subjected to cecal ligation and puncture to induce polymicrobial sepsis and then given an intraperitoneal injection of Gln, Leu, or Gln plus Leu beginning at 1 h after the operation with re-injections every 24 h. All mice were sacrificed on either day 1 or day 4 after the operation.

Intravenous calcitriol administration modulates mesenteric lymph node CD4 T-cell polarization and attenuates intestinal inflammation in obese mice complicated with polymicrobial sepsis.

Background: Sepsis is a lethal syndrome with T-cell dysregulation, imbalanced inflammatory reactions, and gastrointestinal dysfunction. Obesity coexistent with sepsis can cause more-deleterious disease outcomes. Vitamin D is a nutrient with immunomodulatory ability and helps maintain intestinal homeostasis.

Surface-Induced Desolvation of Hydronium Ion Enables Anatase TiO as an Efficient Anode for Proton Batteries.

Hydrogen ion is an attractive charge carrier for energy storage due to its smallest radius. However, hydrogen ions usually exist in the form of hydronium ion (HO) because of its high dehydration energy; the choice of electrode materials is thus greatly limited to open frameworks and layered structures with large ionic channels. Here, the desolvation of HO is achieved by using anatase TiO as anodes, enabling the H intercalation with a strain-free characteristic.
