BACKGROUND: The aims of this study were to summarize the clinical presentation and histological results of 20 cases of complicated Meckel diverticulum (MD) who were presumed to have acute appendicitis before surgery, as well as to improve the diagnosis and treatment of complicated MD in children.
MATERIALS AND METHODS: We retrospectively reviewed the records of 20 complicated MD admitted to our institution who were preoperatively diagnosed with acute appendicitis from January 2012 to January 2019. Patients were divided into the perforated MD group and the Meckel's diverticulitis group. Patient demographics, clinical manifestations, laboratory data, auxiliary examinations, surgical methods, and the result of heterotopic tissue were recorded.
RESULTS: A total of 20 cases of complicated MD (perforated or diverticulitis) were identified. Children were aged from 3 to 13 years, with a mean age of 7.75 years (median 7.75; range, 1-13 years). Perforated Meckel's diverticulum occurred in 5 of 20 (25%) cases. For perforated MD versus diverticulitis, no significant differences were found between age, time to intervention, length of hospital stay, and distance from the ileo-cecal valve. Heterotopic tissue was confirmed on histopathology in 75% of all patients, including 10 cases of gastric mucosa, 3 cases of coexistent gastric mucosa and pancreatic tissue, and 2 cases of pancreatic tissue. All patients underwent diverticulectomy or partial ileal resection under laparoscopy or laparotomy; two cases combined with appendectomy owing to slight inflammation of the appendix.
CONCLUSIONS: The most common presentation of symptomatic MD is painless rectal bleeding; however, it can present symptoms of acute abdomen mimicking acute appendicitis. The key point of diverticulectomy is to remove the ectopic mucosa completely.
The planned research work will investigate structural changes in DNA caused by loosely ionizing and high-LET (Linear Energy Transfer) radiation as well as their attribution to double-strand break repair pathways, which will be analysed in parallel using modern microscopy methods. Our aim is to incorporate sequencing technologies into the spectrum of methods used in radiation research and radiation protection. It is important for us to consider the practical requirements of radiation protection and to extend our experimental approaches to cell types relevant to radiation protection. For this reason, we have now created a separate work program that will focus specifically on sequence analyses in irradiated human lymphocytes. The aim is to successfully transfer the experimental approaches and bioinformatic analyses established in previous experiments in human skin fibroblasts to lymphocytes. Subjects can donate blood samples on a voluntary basis at predetermined times. Only subjects without previous radiotherapy, chemotherapy, immunotherapy, targeted therapy, etc. and without a previous tumor diagnosis in the medical history and in good performance status (ECOG 0-1) will be included.
A standard 30-minute electrophysiological (EP) cardiac stimulation protocol will be performed at the end of the ICD implant at baseline. Participants will be followed up for at least 12 months for endpoints.
Tuberculosis is a daunting global health problem. The solution requires development of an effective vaccine. But incomplete understanding of Mycobacterium tuberculosis (MTB) immunity-how it is acquired, how it is measured-limits vaccine development to empiric rather than rational approaches. New perspectives are needed. Most individuals infected with MTB never actually develop active tuberculosis. Similarly, most individuals with treated tuberculosis or BCG vaccination are also protected from subsequent disease. These individuals may be said to be immune. One approach to obtaining greater understanding of MTB immunity is to study these individuals to discover mechanisms of immunity that mediate their protection from disease. Because it is already known that CD4+ T cells are a critical component of MTB immunity, studying CD4+ T cell responses to MTB infection in immune individuals is a reasonable starting point. To determine which CD4+ T cell subsets and which CD4+ T cell immune responses are important, we will compare individuals with prior exposure (immunity) to MTB to individuals with active tuberculosis. Because HIV infection interferes with the CD4+ T cell response to MTB, it dramatically increases the risks for acquiring MTB infection and for developing disease. Under these circumstances it is easier to discern mechanisms relevant to MTB immunity because of exaggerated MTB-specific responses. In this study we aim to identify CD4+ T cell subsets and responses that correlate with MTB immunity. We anticipate that these correlations will yield new insight into mechanisms of MTB immunity that will be relevant to vaccine development. In addition, by examining MTB immunity in the setting of HIV coinfection, we anticipate new insights into mechanisms of how HIV causes disease.
PURPOSE:To obtain an anti-Lewis blood group analogous antibody having high titer and useful for the determination of the Lews blood group of man and the detection of liquid antigen, etc., by separating a polysaccharide fraction from the extract of gamopetalous plant, apopetalous plant, etc., and sensitizing an animal with said fraction. CONSTITUTION:A gamopetalous plant, apopetalous plant, monocotyledonous plant or pteridophytic plant is extracted with water or an aqueous solution of salt, the extract liquid is fractionated with water and water-soluble organic solvent, and the resultant precipitate is separated and purified to obtain a polysaccharide fraction having Lewis blood group analogous activity. The objective anti-Le<a> analogous antibody and anti-Le<b> analogous antibody can be produced by sensitizing an animal with said fraction. The plant is preferably wormwood belonging to Compositae or Japanese angelica tree belonging to Aradiaceae. An anti-Lewis blood group analogous antibody having high titer can be produced from an easily available plant. In contrast with conventional process, the blood group can be determined by the use of saliva, without necessitating the papain- treatment of blood.

A major hurdle in the treatment of cancer is chemoresistance induced under hypoxia that is characteristic of tumor microenvironment. Triptolide, a potent inhibitor of eukaryotic transcription, possesses potent antitumor activity. However, its clinical potential has been limited by toxicity and water solubility. To address those limitations of triptolide, the present disclosure designed and synthesized glucose-triptolide conjugates (glutriptolides) and demonstrated their antitumor activity  in vitro  and  in vivo . The glutriptolides disclosed herein possess improved stability in human serum, greater selectivity towards cancer over normal cells and increased potency against cancer cells. Importantly, the glutriptolides are more potent against cancer cells under hypoxic conditions in contrast to existing cytotoxic drugs. These glutriptolides also exhibit sustained antitumor activity, prolonging survival in a prostate cancer metastasis animal model. Together, these findings suggest a new strategy to overcome chemoresistance through conjugation of cytotoxic agents to glucose.
Over 500,000 inguinal hernia repairs(IHR) are performed in the United States annually. This is also one of the most common operations performed on the primarily young, male Active Duty population. A common source of morbidity after IHR is chronic groin pain(CGP), usually defined as pain lasting longer than 3 months. The incidence of CGP varies widely in published reports, but in the majority it is 25 to 30%. A major etiology of CGP is thought to be injury to inguinal nerves during surgery. Gabapentin is an anticonvulsant that is also of benefit in the treatment of neuropathic pain. Numerous studies have shown that gabapentin can decrease perioperative pain in patients undergoing surgeries such as hysterectomy, cholecystectomy and spine surgery. Doses and medication regimens varied in these studies, One study in patients undergoing IHR who received a single dose of gabapentin preoperatively, showed a decrease in postoperative pain and in reported pain scores in the first 6 months. We propose a randomized, double-blind, placebo controlled study of the effect of gabapentin on CGP after IHR. Patients will be given placebo or gabapentin. Those given gabapentin, will be given 300 mg orally three times daily for a total of six doses with the first dose given on the morning of surgery. Patients will be evaluated preoperatively and at 1, 6, 12 and 24 months after surgery. Their pain will be assessed with a visual analogue scale. For those reporting pain, the need for pain medication, or other treatment, and the effect of pain on their quality of life will be recorded.
PROBLEM TO BE SOLVED: To lighten the load of the setting of a care plan by providing a means for requesting transmission of a care-support-center side device, a means for transmitting approval data to the care-support-center side device, a means for setting a care plan by using the transmitted approval data, etc. SOLUTION: An approval data request process part 301 makes a request to transmit the approval data showing the need to take care of a care requiring person to the care-support-center side device 121. A care plan setting process part 302 sets the care plan by using the transmitted approval data. A reserving process part 303 reserves the offering of care service on the care-service-support side device according to the set care plan. A care plan transmitting process part 304 transmits the set care plan to a care-requiring-person side device. Basic information on the name, address, etc., of the care requiring person and information on an implementation survey taken by an insurer for care approval are provided for the care support center, so the load of the setting of the care plan can be lightened.
Purpose and hypothesis The aim of this study will be to test the hypothesis that stable sleep, as defined by a consistent (low variability) bedtime and wake-time schedule, will diminish the negative effect of sleep deprivation on vascular function.

Study design and procedures Thirty adults (15 men, 15 women) will complete a 6-week study that will involve five study visits. The first visit will include informed consent, collection of demographic data, sleep- and health-related surveys, and familiarization with study procedures. Participants will then be block randomized to either habitual sleep followed by stable sleep, or stable sleep followed by habitual sleep - each sleep condition will lasts two weeks. In the habitual sleep condition, participants will be asked to follow their normal routine without concern about their sleep duration. In the stable sleep condition, participants will be asked to keep the same bedtime and wake-time schedule without deviation. Bedtime and wake-times will be determined by the researchers, but individualized for each participant so that their usual sleep duration (based on self-report) is met. Sleep will be monitored throughout the study using research-grade motion sensors worn at the wrist. Resting blood pressure, blood vessel vasodilatory function, and cardiovascular responses to exercise will be our main outcome variables. These variables will be measured before (on day #13) and after (on day #14) one night of sleep deprivation. Total sleep deprivation is a well-established experimental model to understand the acute effects of insufficient sleep on vascular function in humans.
The cloning of leptin 30 years ago in 1994 was an important milestone in obesity research. Prior to the discovery of leptin, obesity was stigmatized as a condition caused by lack of character and self-control. Mutations in either leptin or its receptor were the first single gene mutations found to cause severe obesity, and it is now recognized that obesity is caused mostly by a dysregulation of central neuronal circuits. Since the discovery of the leptin-deficient obese mouse (ob/ob) the cloning of leptin (ob aka lep) and leptin receptor (db aka lepr) genes, we have learned much about leptin and its action in the central nervous system. The first hope that leptin would cure obesity was quickly dampened because humans with obesity have increased leptin levels and develop leptin resistance. Nevertheless, leptin target sites in the brain represent an excellent blueprint to understand how neuronal circuits control energy homeostasis. Our expanding understanding of leptin function, interconnection of leptin signaling with other systems and impact on distinct physiological functions continues to guide and improve the development of safe and effective interventions to treat metabolic illnesses. This review highlights past concepts and current emerging concepts of the hormone leptin, leptin receptor signaling pathways and central targets to mediate distinct physiological functions.

A double-blind cross-over placebo-controlled study design will be used to determine the extent to which NOX and creatine monohydrate supplementation influences skeletal muscle microvascular blood flow and endothelial function following the administration of a high carbohydrate meal in sedentary individuals with overweight/obesity. Participants will be initially screened through a telephone screening over the phone or through an electronic copy (Qualtrics survey) and upon meeting the inclusion criteria, will be scheduled for a baseline visit. At the baseline visits participants will go through an informed consent, background and medical history questionnaire alongside a Dual-energy X-ray absorptiometry (DXA) scan and indirect calorimetry. Subsequently, participants will undergo two main testing days, one will occur before supplementation (creatine monohydrate or placebo) and the other following five days of supplementation (creatine monohydrate or placebo). At the main testing days participants will have their resting blood flow and endothelial function assessed before and for 4 hours following the consumption of a high carbohydrate meal. Following the two main testing days in the first study arm, participants will then undergo a 4-week wash-out in which they will resume their normal behavior and stop taking the supplement they were provided. After the washout period, participants will come back and repeat the baseline visit and the two main testing days. The only difference is that participants will receive the other treatment that was not received the first time (creatine monohydrate or placebo). Which treatment the participant receives first or second will be at random.
PROBLEM TO BE SOLVED: To obtain a composite powder suffering reduced sulfur agglomeration and precipitation and being excellent in dispersibility by coating the surface of a powder having a specified particle diameter with sulfur and to obtain a cosmetic containing the same and having excellent stability and excellent feeling of use. SOLUTION: This powder is one obtained by coating the surface of (B) a powder having a mean-particle diameter of 5 μm or below with (A) sulfur. It is desirable that the mixing ratio A/B is 1/(0.01-50) by weight. A composite powder having more excellent dispersibility is obtained by surface-treating the above sulfur-coated powder with (A) a silylating agent having a polyoxyalkylene group in the molecule. The mixing ratio among components A to C is desirably such that the ratio (A+B)/C is 1/(0.01-5) by weight. Component B is not particularly limited and may be any of inorganic and organic powders usually used in cosmetics. An example of the process for producing the above powder consists of dissolving component A in an organic solvent, adding component B to the solution under agitation, and evaporating the solvent from the mixture.
Patients will be given standard vitamin D3 supplementation during transplant in accordance with standard of care per Endocrine Society Guidelines. This supplementation is based on a patient's initial vitamin D level.
BACKGROUNDThe molecular signature of pediatric acute respiratory distress syndrome (ARDS) is poorly described, and the degree to which hyperinflammation or specific tissue injury contributes to outcomes is unknown. Therefore, we profiled inflammation and tissue injury dynamics over the first 7 days of ARDS, and associated specific biomarkers with mortality, persistent ARDS, and persistent multiple organ dysfunction syndrome (MODS).METHODSIn a single-center prospective cohort of intubated pediatric patients with ARDS, we collected plasma on days 0, 3, and 7. Nineteen biomarkers reflecting inflammation, tissue injury, and damage-associated molecular patterns (DAMPs) were measured. We assessed the relationship between biomarkers and trajectories with mortality, persistent ARDS, or persistent MODS using multivariable mixed effect models.RESULTSIn 279 patients (64 [23%] nonsurvivors), hyperinflammatory cytokines, tissue injury markers, and DAMPs were higher in nonsurvivors. Survivors and nonsurvivors showed different biomarker trajectories. IL-1α, soluble tumor necrosis factor receptor 1, angiopoietin 2 (ANG2), and surfactant protein D increased in nonsurvivors, while DAMPs remained persistently elevated. ANG2 and procollagen type III N-terminal peptide were associated with persistent ARDS, whereas multiple cytokines, tissue injury markers, and DAMPs were associated with persistent MODS. Corticosteroid use did not impact the association of biomarker levels or trajectory with mortality.CONCLUSIONSPediatric ARDS survivors and nonsurvivors had distinct biomarker trajectories, with cytokines, endothelial and alveolar epithelial injury, and DAMPs elevated in nonsurvivors. Mortality markers overlapped with markers associated with persistent MODS, rather than persistent ARDS.FUNDINGNIH (K23HL-136688, R01-HL148054).
