[Research progress on the application of time-restricted eating in adult obesity and related metabolic diseases].

The soaring prevalence of obesity and its complications presents a significant health care burden, and there is currently a lack of effective and sustainable treatment methods. Time-restricted eating (TRE) is a specific intermittent fasting (IF) protocol involving consistent fasting and eating periods within a 24-hour cycle. Time-restricted eating can restore robust circadian rhythms and improve metabolic health, providing an emerging dietary strategy for the prevention and treatment of obesity and related metabolic diseases. Previous TRE trials laid the groundwork, and indicate a need for further clinical research including large-scale controlled trials to determine TRE efficacy and the mechanisms by which it may affect humans.

Profiles of gut microbiota in children with obesity from Harbin, China and screening of strains with anti-obesity ability in vitro and in vivo.

AIMS: The purpose of this study was to investigate the characteristics of gut microbiota of children with obesity in Harbin, China and to screen anti-obesity strains in vitro and in vivo. METHODS AND RESULTS: The gut microbiota of children with obesity and normal-weight children were investigated by high-throughput sequencing, and based on the different composition in gut microbiota, the strains with potential anti-obesity properties were screened in vitro and in vivo. Compared with normal-weight children, the Firmicutes to Bacteroidetes ratio in children with obesity decreased. Moreover the relative abundances of Lactobacillus and Bifidobacterium in children with obesity were decreased, while the relative abundance of Akkermansia increased. After a series of screening in vitro and in vivo, nine strains were found inhibiting the body weight gain of HFD-fed mice, of which two strains showed significant effects (P < 0·05). CONCLUSIONS: There were significant changes in gut microbiota of children with obesity from Harbin, China. The obtained strains showed obvious anti-obesity effects, and the screening methods used in this study were effective. SIGNIFICANCE AND IMPACT OF THE STUDY: This study enriched the research results on the characteristics of gut microbiota of children with obesity in different regions of the world. Moreover we established a new and effective method for screening anti-obesity strains, and obtained effective strains.

[Detection and evaluation of SARS-CoV-2 nucleic acid contamination in corona virus disease 19 ward surroundings and the surface of medical staff's protective equipment].

OBJECTIVE: To determine the environmental contamination degree of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in corona virus disease 2019 (COVID-19) wards, to offer gui-dance for the infection control and to improve safety practices for medical staff, by sampling and detecting SARS-CoV-2 nucleic acid from the air of hospital wards, the high-frequency contact surfaces in the contaminated area and the surfaces of medical staff's protective equipment in a COVID-19 designated hospital in Wuhan, China. METHODS: From March 11 to March 19, 2020, we collected air samples from the clean area, the buffer room and the contaminated area respectively in the COVID-19 wards using a portable bioaerosol concentrator WA-15. And sterile premoistened swabs were used to sample the high-frequency contacted surfaces in the contaminated area and the surfaces of medical staff's protective equipment including outermost gloves, tracheotomy operator's positive pressure respiratory protective hood and isolation clothing. The SARS-CoV-2 nucleic acid of the samples were detected by real-time fluorescence quantitative PCR. During the isolation medical observation period, those medical staff who worked in the COVID-19 wards were detected for SARS-CoV-2 nucleic acid with oropharyngeal swabs, IgM and IgG antibody in the sera, and chest CT scans to confirm the infection status of COVID-19. RESULTS: No SARS-CoV-2 nucleic acid was detected in the tested samples, including the 90 air samples from the COVID-19 wards including clean area, buffer room and contaminated area, the 38 high-frequency contact surfaces samples of the contaminated area and 16 surface samples of medical staff's protective equipment including outermost gloves and isolation clothing. Moreover, detection of SARS-CoV-2 nucleic acid by oropharyngeal swabs and IgM, IgG antibodies in the sera of all the health-care workers who participated in the treatment for COVID-19 were all negative. Besides, no chest CT scan images of medical staff exhibited COVID-19 lung presentations. CONCLUSION: Good ventilation conditions, strict disinfection of environmental facilities in hospital wards, guidance for correct habits in patients, and strict hand hygiene during medical staff are important to reduce the formation of viral aerosols, cut down the aerosol load, and avoid cross-infection in isolation wards. In the face of infectious diseases that were not fully mastered but ma-naged as class A, it is safe for medical personnel to be equipped at a high level.

[Consideration of surgeons participating in 2019 coronavirus disease emergency medical rescue].

As a newly epidemic, 2019 coronavirus disease (COVID-19) with a concentrated outbreak poses a great challenge to medical treatment. The severe and critical patients are complex complicatied with the psychological problems, and the medical staff are overworked and under tremendous psychological pressure. The surgeon participated in emergency medical rescue could provide professional treatment for the patients combined with surgical diseases, as well as specialized training for the non-surgeon crew, to reduce surgical-related mortality. With the advantages of good team consciousness, strong aseptic concept and good psychological quality, the surgeons can quickly adapt to and carry out rescue work under the premise of good self-protection. Surgeons need to develop critical care management concepts and focus on the critical care support equipment. Some suggestions are put forward for the standardized training of resident surgeons to cultivate compound talents. It is hoped that this article can lead to the thinking of how to participate in the emergency medical rescue of infectious diseases among surgeons and provide some enlightenment for future surgical education.

Methods: China Information System for Disease Control and Prevention had exported the network report data of "occupational diseases and occupational health information monitoring" from January 1, 2008 to December 31, 2018 and had created the database; The epidemiological characteristics, clinical manifestations and laboratory examinations of OB were analyzed. Results: There were 262 OB cases in Hulunbuir from 2008 to 2018, including male in 235 cases, female in 27 cases. The most age was 41-50 years old (97 cases, 37%) . The length of service was concentrated in 0-10 years (146 cases, 55.7%) ; in the time distribution, the incidence in January was mostly (87 cases, 33.2%) . The industry distribution of veterinarians was the most (139 cases, 53.1%) , followed by epidemic prevention workers (58 cases, 22.1%) . The regional distribution is mainly concentrated in Ergun city (51 cases, 19.5%) , Hailar District (43 cases, 16.4%) , Orogen Autonomous Banner (40 cases, 15.3%) . The main clinical features were asthenia (194 cases, 74.0%) , hyperhidrosis (144 cases, 55.0%) , joint and muscle pain (156 cases, 59.5%) . The course of disease was mostly chronic (181 cases, 69.1%) . Conclusion: The cases of OB in Hulunbuir city are distributed in the developed areas of animal husbandry, and the incidence months are concentrated. Veterinarians are the key high-risk occupational groups.

Cervical ripening agent dinoprostone for delivery induction in late pregnancy mothers: experiences of 685 cases.

The failure of labor induction often requires following cesarean section and suffering of patients. Cervical ripening is therefore critical in clinical care of pregnant mothers. The present study demonstrated the use of dinoprostone in cervical ripening for delivery induction in 685 cases of pregnancy mothers. The authors conclude that dinoprostone is a very useful and safe drug for delivery induction. The combined use of oxytocin and careful monitoring of all body symptoms are important for the clinical safety.

Roles of Baseline Intrinsic Capacity and its Subdomains on the Overall Efficacy of Multidomain Intervention in Promoting Healthy Aging among Community-Dwelling Older Adults: Analysis from a Nationwide Cluster-Randomized Controlled Trial.

BACKGROUND: Impaired intrinsic capacity (IC), which affects approximately 90% of older adults, is associated with a significantly heightened risk of frailty and cognitive decline. Existing evidence suggests that multidomain interventions have the potential to enhance cognitive performance and yield positive effects on physical frailty. OBJECTIVE: To examine roles of baseline IC and its subdomains on the efficacy of multidomain interventions in promoting healthy aging in older adults. DESIGN: a cluster-randomized controlled trial. SETTING AND PARTICIPANTS: 1,054 community-dwelling older adults from 40 community-based clusters across Taiwan. INTERVENTION: A 12-month pragmatic multidomain intervention of exercise, cognitive training, nutritional counseling and chronic condition management. MEASUREMENTS: Baseline IC was measured by 5 subdomains, including cognition (Montreal Cognitive Assessment, MoCA), sensory (visual and hearing impairment), vitality (handgrip strength or Mini-Nutritional Assessment-short form), psychological well-being (Geriatric Depression Scale-5), and locomotion (6m gait speed). Outcomes of interest were cognitive performance (MoCA scores) and physical frailty (CHS frailty score) over a follow-up period of 6 and 12 months. RESULTS: Of all participants (mean age:75.1±6.4 years, 68.6% female), about 90% participants had IC impairment at baseline (2.0±1.2 subdomains). After covariate adjustment using a generalized linear mixed model (GLMM), the multidomain intervention significantly prevented cognitive declines and physical frailty, particularly in those with IC impairment ≥ 3 subdomains (MoCA: coefficient: 1.909, 95% CI: 0.736 ~ 3.083; CHS frailty scores: coefficient = -0.405, 95% CI: -0.715 ~ -0.095). To assess the associations between baseline poor capacity in each IC subdomain and MoCA/CHS frailty scores over follow-up, a 3-way interaction terms (time*intervention*each poorer IC subdomains) were added to GLMM models. Significant improvements in MoCA scores were shown for participants with poorer baseline cognition (coefficient= 1.138, 95% CI: 0.080 ~ 2.195) and vitality domains (coefficient= 1.651, 95% CI: 0.541 ~ 2.760). The poor vitality domain also had a significant modulating effect on the reduction of CHS frailty score after the 6- and 12-month intervention period (6 months: coefficient= -0.311, 95% CI: -0.554 ~ -0.068; 12 months: coefficient= -0.257, 95% CI: -0.513 ~ -0.001). CONCLUSION AND IMPLICATIONS: A multidomain intervention in community-dwelling older adults improves cognitive decline and physical frailty, with its effectiveness influenced by baseline IC, highlighting the importance of personalized strategies for healthy aging.

Comparison of the efficacy of febuxostat vs. benzbromarone in the treatment of gout: a meta-analysis in Chinese gout patients.

OBJECTIVE: Febuxostat and benzbromarone are two common drugs for the treatment of gout, but the clinical efficacy of these two drugs is controversial. This meta-analysis aimed to compare the efficacy of febuxostat and benzbromarone in the treatment of gout. MATERIALS AND METHODS: PubMed, Embase, and the Cochrane Library were searched for articles related to febuxostat and benzbromarone in the treatment of gout from inception to January 7, 2023. Titles and abstracts were reviewed in accordance with predesigned inclusion and exclusion criteria, and data were extracted independently. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the studies, and the continuous variables were expressed as the standard mean square error (SMD) by STATA 16 (Stata Corp., College Station, TX, USA). The sensitivity analysis was conducted by randomly removing a study, and the heterogeneity was analyzed by funnel plots and Egger's test. RESULTS: According to the search strategy, a total of 1,043 publications were retrieved from the three aforementioned databases, of which 45 publications were excluded due to duplication. Fourteen studies remained after screening titles and abstracts, and a total of 7 studies met the inclusion criteria after a comprehensive evaluation of the 14 studies. Meta-analysis showed that the uric acid (UA)-reducing effect of febuxostat is better than that of benzbromarone, while febuxostat showed a better ability to improve the estimated glomerular filtration rate (eGFR) and reduce Cr and blood urea nitrogen (BUN). In terms of hepatotoxicity, benzbromarone was not as potent as febuxostat in increasing alanine transaminase (ALT) and aspartate transaminase (AST), suggesting that benzbromarone has less hepatotoxicity. Moreover, there was no significant difference in the effect on blood lipid levels between the two drugs. CONCLUSIONS: The beneficial effect of febuxostat on renal function-related indexes such as the eGFR, Cr and BUN is significant, while benzbromarone is more effective in reducing UA and has relatively less hepatotoxicity. The specific efficacy of the two drugs needs to be confirmed by further research.

Impetigo herpetiformis with gestational hypertension: a case report and literature review.

BACKGROUND: Impetigo herpetiformis (IH) is a rare skin disorder that occurs during pregnancy. It was previously associated with high maternal and fetal mortality and morbidity, but now has a better prognosis. CASE REPORT: We report a case of a pregnant woman with IH who presented with generalized erythematous pustular eruptions in the 32nd week of gestation. The IH progressed rapidly, and gestational hypertension was observed in the 36th week. The lesions did not subside, despite treatment with corticosteroids and phototherapy. She delivered a healthy male baby via cesarean section in the 37th week. One month after her delivery, her skin returned to normal, except for residual pigmentation, with complete recovery 3 months postpartum. CONCLUSION: An experienced medical team comprising obstetricians, dermatologists, perinatologists and neonatologists is critical to aggressively treat this life-threatening specific dermatosis of pregnancy and to prevent ensuing complications, such as fluid and electrolyte imbalance, secondary infection and placental insufficiency.

Etiologies of severe acute respiratory infection (SARI) and misdiagnosis of influenza in Indonesia, 2013-2016.

BACKGROUND: Severe acute respiratory infection (SARI) accounts for a large burden of illness in Indonesia. However, epidemiology of SARI in tertiary hospitals in Indonesia is unknown. This study sought to assess the burden, clinical characteristics, and etiologies of SARI and concordance of clinical diagnosis with confirmed etiology. METHODS: Data and samples were collected from subjects presenting with SARI as part of the acute febrile Illness requiring hospitalization study (AFIRE). In tertiary hospitals, clinical diagnosis was ascertained from chart review. Samples were analyzed to determine the "true" etiology of SARI at hospitals and Indonesia Research Partnership on Infectious Diseases (INA-RESPOND) laboratory. Distribution and characteristics of SARI by true etiology and accuracy of clinical diagnosis were assessed. RESULTS: Four hundred and twenty of 1464 AFIRE subjects presented with SARI; etiology was identified in 242 (57.6%), including 121 (28.8%) viruses and bacteria associated with systemic infections, 70 (16.7%) respiratory bacteria and viruses other than influenza virus, and 51 (12.1%) influenza virus cases. None of these influenza patients were accurately diagnosed as having influenza during hospitalization. CONCLUSIONS: Influenza was misdiagnosed among all patients presenting with SARI to Indonesian tertiary hospitals in the AFIRE study. Diagnostic approaches and empiric management should be guided by known epidemiology. Public health strategies to address the high burden of influenza should include broad implementation of SARI screening, vaccination programs, clinician education and awareness campaigns, improved diagnostic capacity, and support for effective point-of-care tests.

Transpedicular instrumentation as an adjunct in the treatment of thoracolumbar and lumbar spine tuberculosis with early stage bone destruction.

OBJECT: Because modern imaging techniques now allow for early diagnosis of spinal tuberculosis, more conservative management options are possible. The authors evaluated the effectiveness of transpedicular instrumentation for treatment of thoracolumbar and lumbar spinal tuberculosis in patients with mild bone destruction and the main symptom of "instability catch" (a sudden painful "snap" that occurs when one extends from a forward bent to an upright position). METHODS: Eighteen patients (nine men and nine women, age range 49-71 years) with spinal tuberculosis were treated with transpedicular instrumentation that was supplemented with posterolateral fusion and chemotherapy. All patients were wheelchair dependent or bed-ridden due to severe instability catch, with a mean symptom duration of 2.5 months (range 1-6 months). Two contiguous vertebrae were involved in 17 patients, and a single vertebrae was involved in one. In five patients mild neurological deficits (Frankel Grade D) were present. During surgery, the screws were implanted into the two nonaffected pedicles nearest the lesion to stabilize the involved segments. No attempt at radical debridement or neural decompression was undertaken. The follow-up period ranged from 21 to 40 months. Postoperatively the instability catch was relieved within 10 days (excellent outcome) and within 1 month (good outcome) in seven and eight patients, respectively, and within 3 months (fair outcome) in two; in the remaining patient, the symptom did not resolve (poor outcome). A short duration of symptoms (generally < 3 months) and bone destruction of less than 50% in the involved vertebral bodies were observed in patients who made a good or excellent outcome. During the follow-up period, good maintenance of spinal alignment, stabilization of the involved segment, and resolution of the inflammatory process were shown; however, there was no strong evidence that fusion had occurred at the bony defect. Patients in whom a fair outcome was achieved experienced a longer duration of symptoms, and in each, one vertebral body with greater than 50% bone destruction was demonstrated. However, good maintenance of spinal alignment was also shown during the follow-up period. The patient whose outcome was poor had the longest history (6 months) of symptoms and the most extensive involvement of the spine (> 50% destruction of two adjacent lumbar vertebral bodies). Postoperatively, implant failure occurred and the patient developed a wound infection. CONCLUSIONS: Transpedicular instrumentation provides rapid relief of instability catch and prevents late angular deformity in patients with thoracolumbar and lumbar spinal tuberculosis in whom limited (< 50%) bone destruction of the involved vertebral bodies has been shown and whose main symptom is instability catch.

Scar endometriosis.

BACKGROUND: Scar endometriosis may develop after pelvic operations, such as cesarean section, tubal ligation, hysterotomy and hysterectomy. This prompted us to demonstrate the proper diagnosis; management and prophylactic procedure of scar endometriosis. METHODS: Twelve patients with scar endometriosis were diagnosed by clinical symptoms and signs, including a painful scar mass related to the menstrual cycle and cyclic bleeding from scars. Preoperative ultrasound needle aspiration cytology was arranged in three patients without painful mass. The management comprised complete surgical excision and selective medical treatment. Postoperative follow-up was scheduled at six-month intervals. RESULTS: Except for two patients who complained of scar pain but no palpable mass during menstruation, there was no evidence of recurrence in the other 10 patients. CONCLUSIONS: Diagnosis of scar endometriosis should involve detailed history taking and pelvic examination. Concerning the role of needle aspiration cytology, it still remains controversial. Several prophylactic procedures have been presented to prevent decidual contamination of the wound. Complete surgical excision including the adjacent fascia or skin is the proper treatment of scar endometriosis.

Efficacy of endoscopic stapled transanal rectal resection for the treatment of rectocele.

OBJECTIVE: The objective of the study was to determine the efficacy of endoscopic stapled transanal rectal resection for the treatment of rectocele. PATIENTS AND METHODS: For this purpose, the data were collected from 61 patients with severe rectocele that underwent endoscopic stapled transanal rectal resection within the time period from April 2010 to April 2012. The pre- and post-operative Longo's obstructed defecation syndrome (ODS) were compared. The reduction of the rectocele was assessed by defecography on visit and from patients' satisfaction obtained through following up. RESULTS: We found that the postoperative Longo's ODS was significantly lower than the preoperative value (p < 0.01); and defecography showed that the rectocele was significantly reduced or disappeared. Furthermore, 57 of the 61 (93.4%) patients expressed their satisfaction at follow up. CONCLUSIONS: The endoscopic stapled transanal rectal resection can be recommended as the treatment of choice for rectocele since it is an easy-to-perform procedure that has satisfactory short and mid to long-term therapeutic efficacy.

Systematic review: faecal microbiota transplantation therapy for digestive and nondigestive disorders in adults and children.

BACKGROUND: There has been growing interest in the use of faecal microbiota transplantation (FMT) for the treatment of gastrointestinal and nongastrointestinal diseases. AIM: To review systematically the reported efficacy and safety of FMT in the management of gastrointestinal and nongastrointestinal disorders in adults and children. METHODS: The systematic review followed Cochrane and PRISMA recommendations. Available articles were identified using three electronic databases in addition to hand searching and contacting experts. Inclusion criteria were any reports of FMT therapy written in English. RESULTS: A total of 844 patients who had undergone FMT were identified from 67 published studies. The most common indications were refractory/relapsing Clostridium difficile infection (CDI) (76.3%) and inflammatory bowel disease (IBD) (13.2%). There has been only one placebo-controlled trial, a successful trial in 43 patients with recurrent CDI. Seven publications report FMT in paediatric patients with a total of 11 treated, 3 with chronic constipation and the remainder with recurrent CDI or ulcerative colitis (UC). 90.7% of patients with refractory/relapsing CDI were cured and 78.4% of patients with IBD were in remission after FMT. FMT therapy could also be effective in treatment of some nongastrointestinal disorders such as chronic fatigue syndrome. The only reported serious adverse event attributed to the therapy was a case of suspected peritonitis. CONCLUSIONS: Although more controlled trials are needed, faecal microbiota transplantation therapy shows promise in both adults and children with gastrointestinal diseases such as CDI and IBD.

Surgery is an effective and reasonable treatment for degenerative scoliosis: a systematic review.

OBJECTIVE: A systematic review to evaluate the role of surgery for treating degenerative scoliosis (DS) in terms of improved function (Oswestry Disability Index [ODI]) and correction of deformity (Cobb angle); safety outcomes included complication and repeat surgery rates. METHODS: A search of the MEDLINE, ISI Web of Knowledge and Cochrane Library databases was performed. The methodological quality of each study was assessed according to standardized criteria and data were extracted. RESULTS: A total of 16 studies including 553 patients with DS met the eligibility criteria for inclusion. The mean ODI score at final follow-up was 36.0 ± 7.8 (304 patients) and the mean decrease in ODI was 23.3 ± 11.3 (302 patients). Mean reduction in curve angle (as a percentage of the original curve) was 48.5 ± 21.0% (527 patients). The overall incidence of complications was 49.0% (171 in 349 patients) and the rate of repeat surgery was 15.3% (61 in 398 patients). CONCLUSIONS: Despite a high incidence of complications and reoperations, surgery was an effective and reasonable treatment for DS, providing significant functional improvement and deformity correction.

Distally based sural island flap for the reconstruction of a large soft tissue defect in an open tibial fracture with occluded anterior and posterior tibial arteries-a case report.

To repair a 10 x 16 cm soft tissue defect of right lower leg that accompanied with occluded anterior and posterior tibial arteries in a 30-year-old man who sustained comminuted type III(B) Gustilo open tibial and fibular fracture, we present a successful reconstruction by using a large distally based sural island flap perfused by the lowermost perforator of the peroneal artery. This flap is a useful alternative for distal extremity reconstruction when anterior and posterior tibial arteries are occluded, as large flaps can be elevated safely based on only one peroneal perforator.

Ultrasonographic and urodynamic evaluation after tension free vagina tape procedure (TVT).

BACKGROUND: This study was carried out to evaluate the urodynamic and ultrasonographic findings after tension-free vagina tape (TVT) procedure on stress urinary incontinent women. METHODS: Ninety women suffering from genuine stress incontinence without pelvic relaxation syndrome underwent surgery. Urodynamic measurement, one-hour pad test and introital ultrasonographic evaluation were performed preoperatively and one year after surgery. Additional ultrasonographic surveillance of the urethra was performed immediately after the operation. The position and mobility of the bladder neck was compared pre- and post-operatively in relation to the inferior edge of the pubic symphysis. RESULT: Eight women were excluded for various reasons. Among the 82 women who completed the study, 76 (93%) were cured, four were improved and two failed. No major intra- or post-operative complications occurred. The position and mobility of the bladder neck showed no significant difference before and after surgery. A urethral knee angle was noted ultrasonographically on cured and improved patients during maximum straining. Nine patients with immediate postoperative voiding difficulty were found to have a pronounced mid-urethra angulation. The symptom and sign were resolved by time after urethra depressing. Urodynamic assessment of the urethral pressure profile and other parameter showed no significant difference before and after the surgery except that a positive pressure transmission in the middle portion of the urethra was noted among 70 (87.5%) of cured and improved subjects. CONCLUSION: Tension-free vagina tape operation is an effective surgical procedure for the treatment of female urinary stress incontinence. The procedure seems neither to change hypermobility nor to elevate the position of bladder neck. Urinary continence after surgery is most probably achieved by creating a dynamic mid-urethral knee angulation by which the urethra is closed i.e. kinked at stress. Lifting of the mid-urethra resulted in postoperative voiding difficulty. It is the important that the tape is placed tension free under the urethra. Introital ultrasonographic surveillance is a suitable technique to visualize the result of the operation.
