Neurodegenerative diseases refer to a battery of medical conditions that affect the survival and function of neurons in the brain, which are mainly presented with progressive loss of cognitive and/or motor function. Acupuncture showed benign effects in improving neurological deficits, especially on movement and cognitive function impairment. Here, we reviewed the therapeutic mechanisms of acupuncture at the neural circuit level in movement and cognition disorders, summarizing the influence of acupuncture in the dopaminergic system, glutamatergic system, γ-amino butyric acid-ergic (GABAergic) system, serotonergic system, cholinergic system, and glial cells at the circuit and synaptic levels. These findings can provide targets for clinical treatment and perspectives for further studies. [ABSTRACT FROM AUTHOR]

Purpose: In the realm of pain management, traditional Chinese medicine, specifically acupuncture, has garnered increasing attention. This meta-analysis pioneers the evaluation of acupuncture's effectiveness in treating insomnia among hypertensive patients. Methods: We conducted a comprehensive search across several databases--PubMed, Web of Science, Cochrane Library, WANFANG, China National Knowledge Infrastructure (CNKI), Sinomed, and the Chinese Journal of Science and Technology (VIP). Additionally, forward and backward articles of studies published from the inception of these databases until 10 September 2023, were reviewed. This systematic review and meta-analysis included all randomized controlled trials (RCTs) focusing on acupuncture for insomnia in hypertensive patients, without imposing language or date restrictions. We rigorously assessed all outcome measures reported in these trials. The evidence was synthesized by calculating the difference between mean differences (MD) in symptom change. The quality of the evidence was determined using the Cochrane Risk of Bias tool. This study is registered with PROSPERO under number CRD42023461760. Results: Our analysis included 16 RCTs, comprising 1,309 patients. The findings revealed that acupuncture was significantly more effective than the control group in reducing insomnia symptoms, as indicated by a greater decrease in the PSQI score (MD = -3.1, 95% CI [-3.77 to -2.62], p < 0.00001). Additionally, improvements in both systolic and diastolic blood pressure were more pronounced in the acupuncture group compared to the control group (SBP: MD = -10.31, 95% CI [-16.98 to -3.64], p = 0.002; DBP: MD = -5.71, 95% CI [-8.19 to -3.23], p < 0.00001). These results suggest that acupuncture not only improves sleep quality but also lowers blood pressure in patients suffering from hypertension and insomnia. Further research is warranted to elucidate optimal acupuncture points and the duration of treatment for maximized therapeutic effect. [ABSTRACT FROM AUTHOR]

Introduction: Diffusion Tensor Imaging (DTI) indicators of different white matter (WM) fibers and brain region lesions for post-stroke aphasia (PSA) are inconsistent in existing studies. Our study examines the consistency and differences between PSA tests performed with DTI. In addition, obtaining consistent and independent conclusions between studies was made possible by utilizing DTI in PSA assessment. Methods: In order to gather relevant studies using DTI for diagnosing PSA, we searched the Web of Science, PubMed, Embase, and CNKI databases. Based on the screening and evaluation of the included studies, the meta-analysis was used to conduct a quantitative analysis. Narrative descriptions were provided for studies that met the inclusion criteria but lacked data. Results: First, we reported on the left hemisphere. The meta-analysis showed that fractional anisotropy (FA) of the arcuate fasciculus (AF) and superior longitudinal fasciculus (SLF), inferior frontal-occipital fasciculus (IFOF), inferior longitudinal fasciculus (ILF), and uncinate fasciculus (UF) were decreased in the PSA group in comparison with the healthy controls (p < 0.00001). However, in the comparison of axial diffusivity (AD), there was no statistically significant difference in white matter fiber tracts in the dual-stream language model of the PSA group. Elevated radial diffusivity (RD) was seen only in the IFOF and ILF (PIFOF = 0.01; PILF = 0.05). In the classic Broca's area, the FA of the PSA group was decreased (p < 0.00001) while the apparent diffusion coefficient was elevated (p = 0.03). Secondly, we evaluated the white matter fiber tracts in the dual-stream language model of the right hemisphere. The FA of the PSA group was decreased only in the IFOF (p = 0.001). AD was elevated in the AF and UF (PAF < 0.00001; PUF = 0.009). RD was elevated in the AF and UF (PAF = 0.01; PUF = 0.003). The other fiber tracts did not undergo similar alterations. Conclusion: In conclusion, DTI is vital for diagnosing PSA because it detects WM changes effectively, but it still has some limitations. Due to a lack of relevant language scales and clinical manifestations, diagnosing and differentiating PSA independently remain challenging. [ABSTRACT FROM AUTHOR]

Background/Aims: The aim of this study was to analyze the chronological changes in postoperative complications in surgical ulcerative colitis patients over the past decade in China and to investigate the potential parameters that contributed to the changes. Methods: Ulcerative colitis patients who underwent surgery during 2008-2017 were retrospectively enrolled from 13 hospitals in China. Postoperative complications were compared among different operation years. Risk factors for complications were identified by logistic regression analysis. Results: A total of 446 surgical ulcerative colitis patients were analyzed. Fewer short-term complications (24.8% vs. 41.0%, P= 0.001) and more laparoscopic surgeries (66.4% vs. 25.0%, P< 0.001) were found among patients who received surgery during 2014-2017 than 2008-2013. Logistic regression suggested that independent protective factors against short-term complications were a higher preoperative body mass index (odds ratio [OR], 0.870; 95% confidence interval [CI], 0.785-0.964; P= 0.008), laparoscopic surgery (OR, 0.391; 95% CI, 0.217-0.705; P= 0.002) and elective surgery (OR, 0.213; 95% CI, 0.067-0.675; P= 0.009). The chronological decrease in short-term complications was associated with an increase in laparoscopic surgery. Conclusions: Our data revealed a downward trend of short-term postoperative complications among surgical ulcerative colitis patients in China during the past decade, which may be due to the promotion of minimally invasive techniques among Chinese surgeons.

Stroke-induced depression is a common complication and an important risk factor for disability. Besides psychiatric symptoms, depressed patients may also exhibit a variety of gastrointestinal symptoms, and even take gastrointestinal symptoms as the primary reason for medical treatment. It is well documented that stress may disrupt the balance of the gut microbiome in patients suffering from post-stroke depression (PSD), and that disruption of the gut microbiome is closely related to the severity of the condition in depressed patients. Therefore, maintaining the balance of intestinal microbiota can be the focus of research on the mechanism of acupuncture in the treatment of PSD. Furthermore, stroke can be effectively treated with acupuncture at all stages and it may act as a special microecological regulator by regulating intestinal microbiota as well. In this article, we reviewed the studies on changing intestinal microbiota after acupuncture treatment and examined the existing problems and development prospects of acupuncture, microbiome, and poststroke depression, in order to provide new ideas for future acupuncture research.

In a case of thalamencephalic and mesencephalic injury secondary to electrical trauma, a 29-year-old patient has been receiving manual acupuncture for 17 months in National Clinical Research Center for Chinese Medicine Acupuncture and Moxibustion. As a result of treatment, the patient’s self-care ability and quality of life have greatly improved. In order to fully understand how acupuncture can benefit neurological sequelae resulting from electrical trauma, further research is needed. Additionally, there should be consideration given to the promotion of acupuncture therapy in the neurological sequelae of electric shock. [ABSTRACT FROM AUTHOR]

Increasing HIV testing, preexposure prophylaxis (PrEP), and antiretroviral therapy (ART) are pillars of the federal Ending the HIV Epidemic in the U.S. (EHE) initiative, with a goal of decreasing new HIV infections by 90% by 2030.* In response to the COVID-19 pandemic, a national emergency was declared in the United States on March 13, 2020, resulting in the closure of nonessential businesses and most nonemergency health care venues; stay-at-home orders also limited movement within communities (1). As unemployment increased during the pandemic (2), many persons lost employer-sponsored health insurance (3). HIV testing and PrEP prescriptions declined early in the COVID-19 pandemic (4-6); however, the full impact of the pandemic on use of HIV prevention and care services and HIV outcomes is not known. To assess changes in these measures during 2019-2021, quarterly data from two large U.S. commercial laboratories, the IQVIA Real World Data - Longitudinal Prescription Database (IQVIA),† and the National HIV Surveillance System (NHSS)§ were analyzed. During quarter 1 (Q1)¶ 2020, a total of 2,471,614 HIV tests were performed, 190,955 persons were prescribed PrEP, and 8,438 persons received a diagnosis of HIV infection. Decreases were observed during quarter 2 (Q2), with 1,682,578 HIV tests performed (32% decrease), 179,280 persons prescribed PrEP (6% decrease), and 6,228 persons receiving an HIV diagnosis (26% decrease). Partial rebounds were observed during quarter 3 (Q3), with 2,325,554 HIV tests performed, 184,320 persons prescribed PrEP, and 7,905 persons receiving an HIV diagnosis. The proportion of persons linked to HIV care, the number who were prescribed ART, and proportion with a suppressed viral load test (<200 copies of HIV RNA per mL) among those tested were stable during the study period. During public health emergencies, delivery of HIV services outside of traditional clinical settings or that use nonclinical delivery models are needed to facilitate access to HIV testing, ART, and PrEP, as well as to support adherence to ART and PrEP medications.

Under the guidance of global natural product social molecular networking, three new indolocarbazoles named streptocarbazoles F-H (1-3), along with staurosporine (4) were isolated from the marine-derived Streptomyces sp. OUCMDZ-5380. Structures of streptocarbazoles F-H were, respectively, determined as N-demethyl-N-hexanoylstaurosporine (1), N-demethyl-N-(2-methyl-3-methoxypyridin-4-yl) staurosporine staurosporine (2), and 4-(N-demethylstaurosporine-N-yl)-1,2-dimethyl-3-methoxypyridinium (3) by spectroscopic analysis and electronic circular dichroism comparison with staurosporine. Compared with staurosporine (4), streptocarbazoles F-H (1-3) showed a selective antiproliferation of the acute myeloid leukemia cell line MV4-11 with the IC50 values of 0.81, 0.55, and 1.88 mM, respectively.

The recent lack of discovery of novel antibiotics and the increase of antibiotic-resistant microorganisms present significant problems in infectious disease therapy. The mangrove forest ecosystem is an important natural source of novel organisms that have high potential to produce bioactive compounds. This study focuses on screening and identification of antimicrobial compound-producing actinobacteria from mangrove sediment samples, determination of some optimal parameters for antimicrobial compound production, as well as characterization of the antimicrobial compounds produced. Among a total of 22 isolates isolated from seven sediment samples, Streptomyces iconiensis OUCMDZ-5511, which was identified by colony morphology and 16S rRNA gene sequence, displayed the broadest antimicrobial spectrum against eight target indicator bacteria. An ethyl acetate (EtOAc) extract from culture broth of S. iconiensis OUCMDZ-5511 had the highest antibacterial activity against Bacillus subtilis ATCC 6051, determined by agar well diffusion method, when this strain was cultured in A1 broth with initial pH of 9.0 and 0% NaCl. According to bioassay-guided chromatography, three interesting antimicrobial compounds, namely 2(3H)-benzothiazolone, indole-3-acetic acid and lumichrome were obtained from culture broth EtOAc extract of S. iconiensis OUCMDZ-5511 after purification by HPLC and structure identification by ESI-MS and NMR. However, only lumichrome showed broad-spectrum antibacterial activity against Salmonella Weltevreden, Staphylococcus aureus, B. subtilis, Micrococcus luteus and Escherichia coli, with MIC and MBC values ranging from 0.125 to 0.5 mg•mL-1 and 0.25 to 1.0 mg•mL-1, respectively. Notably, this study is the pioneer report on identification of 2(3H)-benzothiazolone, indole-3-acetic acid, and lumichrome in EtOAc extract from culture broth of S. iconiensis.

HIV testing is a critical component of effective HIV prevention and care. CDC recommends routine opt-out HIV testing in health care settings for all sexually active persons aged 13-64 years at least once in their lifetime and risk-based testing regardless of age for those who report behaviors associated with HIV acquisition (1). However, recent studies show low HIV testing rates in clinical settings; HIV testing rates at visits to physician offices did not increase during 2009-2016 (2). The objective of the current study is to estimate temporal trends in HIV testing among persons with commercial insurance or Medicaid from 2014 through 2019 and describe their demographic characteristics in 2019. Weighted data from the IBM MarketScan Commercial Claims and Encounters database* (commercial insurance) and from the Centers for Medicare & Medicaid Services (CMS) claims database† (Medicaid) were analyzed to estimate the proportions of persons with commercial insurance or Medicaid who received testing for HIV. Testing rates increased among male and nonpregnant female persons aged ≥13 years with either type of coverage. In 2019, only 4.0% of those with commercial insurance and 5.5% of those with Medicaid received testing for HIV. Testing rates were higher among non-Hispanic Black or African American (Black) persons and Hispanic or Latino (Hispanic) persons. Based on mathematical modeling studies, these annual testing rates would need to increase at least threefold and be sustained over several years (3,4) to achieve the Ending the HIV Epidemic (EHE) in the U.S. initiative goal of ≥95% of persons with HIV being aware of their infection by 2025.§ Interventions need to be implemented to increase routine and risk-based HIV testing in clinical settings to higher levels that can help reduce disparities in HIV diagnoses between Black and Hispanic persons compared with non-Hispanic White (White) persons (5). Increased HIV testing is essential to achieve the goals of the EHE initiative and reduce disparities in HIV diagnoses; public health should partner with health care systems to implement interventions that support increased testing.

Background: Use of HIV preexposure prophylaxis (PrEP) has increased nationwide, but the magnitude and distribution of PrEP medication costs across the health care system are unknown.Objective: To estimate out-of-pocket (OOP) and third-party payments using a large pharmacy database.Design: Retrospective cohort study.Setting: Prescriptions for tenofovir disoproxil fumarate with emtricitabine (TDF-FTC) for PrEP in the United States in the IQVIA Longitudinal Prescriptions database, which covers more than 90% of retail pharmacy prescriptions.Measurements: Third-party, OOP, and total payments were compared by third-party payer, classified as commercial, Medicaid, Medicare, manufacturer assistance program, or other. Missing payment data were imputed using a generalized linear model to estimate overall PrEP medication payments.Results: Annual PrEP prescriptions increased from 73 739 to 1 100 684 during 2014 to 2018. Over that period, the average total payment for 30 TDF-FTC tablets increased from $1350 to $1638 (5.0% compound annual growth rate) and the average OOP payment increased from $54 to $94 (14.9% compound annual growth rate). Of the $1638 in total payments per 30 TDF-FTC tablets in 2018, OOP payments accounted for $94 (5.7%) and third-party payments for $1544 (94.3%). Out-of-pocket payments per 30 tablets were lower among Medicaid recipients ($3) than among those with Medicare ($80) or commercial insurance ($107). Payments for PrEP medication in the IQVIA database in 2018 totaled $2.08 billion; $1.68 billion (80.7%) originated from prescriptions for persons with commercial insurance, $200 million (9.6%) for those with Medicaid, $48 million (2.3%) for those with Medicare, and $127 million (6.1%) for those with manufacturer assistance.Limitation: The IQVIA database does not capture every prescription nationwide.Conclusion: Third-party and OOP payments per 30 TDF-FTC tablets increased annually. The $2.08 billion in PrEP medication payments in 2018 is an underestimation of national costs. High costs to the health care system may hinder PrEP expansion.Primary Funding Source: Centers for Disease Control and Prevention. [ABSTRACT FROM AUTHOR]

In 2019, the U.S. Department of Health and Human Services launched the Ending the HIV Epidemic: A Plan for America (EHE) initiative to end the U.S. human immunodeficiency virus (HIV) epidemic by 2030. A critical component of the EHE initiative involves early diagnosis of HIV infection, along with prevention of new transmissions, treatment of infections, and response to HIV outbreaks (1). HIV testing is the first step in identifying persons with HIV infection who need to be engaged in treatment and care as well as persons with a negative HIV test result and who are at high risk for infection and can benefit from HIV preexposure prophylaxis (PrEP) and other prevention services. These opportunities are often missed for persons receiving clinical services in ambulatory care settings (2). Data from the 2009-2016 National Ambulatory Medical Care Survey (NAMCS) and 2009-2017 National Hospital Ambulatory Medical Care Survey (NHAMCS) were analyzed to estimate trends in HIV testing at visits by males and nonpregnant females to physician offices, community health centers (CHCs), and emergency departments (EDs) in the United States. HIV tests were performed at 0.63% of 516 million visits to physician offices, 2.65% of 37 million visits to CHCs, and 0.55% of 87 million visits to EDs. The percentage of visits with an HIV test did not increase at visits to physician offices during 2009-2016, increased at visits to CHC physicians during 2009-2014, and increased slightly at visits to EDs during 2009-2017. All adolescents and adults should have at least one HIV test in their lifetime (3). Strategies that reduce clinical barriers to HIV testing (e.g., clinical decision supports that use information in electronic health records [EHRs] to order an HIV test for persons who require one or standing orders for routine opt-out testing) are needed to increase HIV testing at ambulatory care visits.

Preexposure prophylaxis (PrEP) with a daily, oral pill containing antiretroviral drugs is highly effective in preventing acquisition of human immunodeficiency virus (HIV) infection (1-4). The combination of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) is the only medication approved by the Food and Drug Administration (FDA) for PrEP. PrEP is indicated for men and women with sexual or injection drug use behaviors that increase their risk for acquiring HIV (5). CDC analyzed 2014-2016 data from the IQVIA Real World Data - Longitudinal Prescriptions (IQVIA database) to estimate the number of persons prescribed PrEP (users) in the United States and to describe their demographic characteristics, including sex and race/ethnicity. From 2014 to 2016, the annual number of PrEP users aged ≥16 years increased by 470%, from 13,748 to 78,360. In 2016, among 32,853 (41.9%) PrEP users for whom race/ethnicity data were available, 68.7% were white, 11.2% were African American or black (black), 13.1% were Hispanic, and 4.5% were Asian. Approximately 7% of the estimated 1.1 million persons who had indications for PrEP were prescribed PrEP in 2016, including 2.1% of women with PrEP indications (6). Although black men and women accounted for approximately 40% of persons with PrEP indications (6), this study found that nearly six times as many white men and women were prescribed PrEP as were black men and women. The findings of this study highlight gaps in effective PrEP implementation efforts in the United States. [ABSTRACT FROM AUTHOR]

Background/Aims:Resection of the diseased segment and suture of the victim segment is recommended for enteroenteric fistula in Crohn's disease (CD). The main difficulty in this procedure remains reliable diagnosis of the victim segment, especially for fistulas found intraoperatively and inaccessible on endoscopic examination. We aimed to explore whether intraoperative inspection alone is reliable. Methods: Patients undergoing conservative surgery between 2011 and 2016 for enteroenteric fistulas complicating CD were identified from a prospectively maintained database. Patients were divided according to whether the victim segment was evaluated by preoperative endoscopy + intraoperative inspection (PI group) or by intraoperative inspection alone (I group). Outcomes were compared. Results: Of 65 patients eligible for the study, 37 were in in the PI group and 28 were in the I group. The baseline characteristics were similar between the groups, except for the rate of emergency surgery (0/37 in PI group vs. 5/28 in I group, P =0.012). Fistulas involved more small intestines (4/37 in PI group vs. 15/28 in I group, P <0.001) and fewer sigmoid colons (17/37 in PI group vs. 4/28 in I group, P =0.008) in I group due to accessibility with endoscopy. No difference was found in postoperative complications, stoma rates, postoperative recurrence, or disease at the repair site between the 2 groups (P >0.05). Conclusions: For fistulas found intraoperatively and inaccessible on endoscopic examination, intraoperative inspection was a reliable guide when choosing between en bloc resection and a conservative procedure.

Background: Since 1968, China has trained about 1.5 million barefoot doctors in a few years' time to provide basic health services to 0.8 billion rural population. China's Ministry of Health stopped using the term of barefoot doctor in 1985, and changed policy to develop village doctors. Since then, village doctors have kept on playing an irreplaceable role in China's rural health, even though the number of village doctors has fluctuated over the years and they face serious challenges. United Nations declared Sustainable Development Goals in 2015 to achieve universal health coverage by 2030. Under this context, development of Community Health workers (CHWs) has become an emerging policy priority in many resource-poor developing countries. China's experiences and lessons learnt in developing and maintaining village doctors may be useful for these developing countries. Methods: This paper aims to synthesis lessons learnt from the Chinese CHW experiences. It summarizes China's experiences in exploring and using strategic partnership between the community and the formal health system to develop CHWs in the two stages, the barefoot doctor stage (1968-1985) and the village doctor stage (1985-now). Chinese and English literature were searched from PubMed, CNKI and Wanfang. The information extracted from the selected articles were synthesized according to the four partnership strategies for communities and health system to support CHW development, namely 1) joint ownership and design of CHW programmes; 2) collaborative supervision and constructive feedback; 3) a balanced package of incentives, both financial and non-financial; and 4) a practical monitoring system incorporating data from the health system and community. Results: The study found that the townships and villages provided an institutional basis for barefoot doctor policy, while the formal health system, including urban hospitals, county health schools, township health centers, and mobile medical teams provided training to the barefoot doctors. But After 1985, the formal health system played a more dominant role in the CHW system including both selection and training of village doctors. China applied various mechanisms to compensate village doctors in different stages. During 1960s and 1970s, the main income source of barefoot doctors was from their villages' collective economy. After 1985 when the rural collective economy collapsed and barefoot doctors were transformed to village doctors, they depended on user fees, especially from drug sale revenues. In the new century, especially after the new round of health system reform in 2009, government subsidy has become an increasing source of village doctors' income. Conclusion: The barefoot doctor policy has played a significant role in providing basic human resources for health and basic health services to rural populations when rural area had great shortages of health resources. The key experiences for this great achievement are the intersection between the community and the formal health system, and sustained and stable financial compensation to the community health workers.

Background: China has a high burden of diabetes mellitus (DM), and a large proportion of DM patients remain untreated for various reasons, including low availability of primary health care providers. DM patient management is one of the priorities in China's national essential public health programs. Shortage of health workforce has been a major barrier to improving access to health care for DM patients. This study examines the impact of the health workforce on outpatient utilization of DM patients. Methods: Data were collected from China National Health Service Surveys in 2008 and 2013, covering 94 rural counties and 156 urban districts, respectively, with a total of 15,984 DM patients. Household data and facility-based data at county/district level were merged. The health workforce was measured by number of physicians per 1,000 population in county hospitals and primary health centers (PHCs), respectively. Health care seeking behavior was measured by health care utilization and distribution of health providers of the DM patients. Multilevel zero-inflated negative binomial regression was used to analyze the impact of the health workforce on outpatient visits by DM patients, and a multilevel, multinomial logit model was used to examine the impact of the health workforce on choice of health providers by DM patients. Results: An increase in the number of physicians at both county hospitals and PHCs was associated with increased outpatient visits by DM patients, particularly more physicians at PHCs. With increased numbers of physicians at PHCs, outpatient visits among residents with DM in rural and western areas of China increased more than those in urban and eastern areas. More physicians at PHCs had a positive impact on improving the likelihood of outpatient visits at PHCs. The positive influence of increasing the number of physicians available to DM patients in rural and western areas was greater than that for urban and eastern DM patients. Conclusions: The health workforce is a key component of any healthcare system and is critical in improving health care accessibility. Strategies to increase coverage of health workforce at PHCs are crucial to achieving adequate levels of health services for DM patients. Allocation of health workforce should focus on PHCs in rural and low-income areas. [ABSTRACT FROM AUTHOR]

In the process of profiling the secondary metabolites of actinobacteria isolated from the Saudi coastal habitats for production of antibiotics and anti-cancer drugs, the cultures of strain WH1 that was identified as Streptomyces heliomycini exhibited strong antibacterial activity against Staphylococcus aureus. By means of MS and NMR techniques, the active compounds were characterized as actinomycins X0β, X2, and D, respectively. The research on the productivity of this strain for actinomycins revealed that the highest production of actinomycins X0β, X2, and D was reached in the medium MII within 5% salinity and pH 8.5. In this optimized condition, the fermentation titers of actinomycins X0β, X2, and D were 107.6 ± 4.2, 283.4 ± 75.3, and 458.0 ± 76.3 mg/L, respectively. All the three actinomycins X0β, X2, and D showed potent cytotoxicities against the MCF-7, K562, and A549 tumor cell lines, in which actinomycin X2 was the most active against the three tumor cell lines with the IC50 values of 0.8--1.8 nM. Both actinomycins X2 and D showed potent antibacterial activities against S. aureus and the methicillin-resistant S. aureus, Bacillus subtilis, and B. cereus and the actinomycin X2 was more potent.

Background/Aims: Chronic intestinal pseudo-obstruction (CIPO) is a serious, life-threatening motility disorder that is often related to bacterial overgrowth. Fecal microbiota transplantation (FMT) results in restoration of the normal intestinal microbial community structure. We investigated the efficacy of FMT in the treatment of CIPO patients. Methods: Nine patients (age 18-53 years) with CIPO were enrolled in this prospective, open-label study. Patients received FMT for 6 consecutive days through nasojejunal (NJ) tubes and were followed up for 8 weeks after treatment. We evaluated the rate of clinical improvement and remission, feeding tolerance of enteral nutrition, and CT imaging scores of intestinal obstructions. Lactulose hydrogen breath tests were performed before FMT and 8 weeks after FMT to evaluate for the presence small intestinal bacterial overgrowth (SIBO). Results: FMT significantly alleviated bloating symptoms, and symptoms of pain were relieved 2 weeks after FMT. Enteral nutrition administered through a NJ tube after FMT was well-tolerated by 66.7% (6/9) of patients. CT scores of intestinal obstructions were significantly reduced after FMT (P = 0.014). SIBO was eliminated in 71.0% (5/7) of patients. Conclusions: This pilot study demonstrated the safety of using FMT. FMT may relieve symptoms in selected patients with CIPO. FMT may also improve patient tolerance of enteral nutrition delivered via a NJ tube. [ABSTRACT FROM AUTHOR]

Background: The ratio of C-reactive protein to albumin, as a novel inflammation-based prognostic score, is associated with outcomes in cancer and septic patients. The diagnostic accuracy of the CRP/albumin ratio has not been assessed in colorectal surgery for postoperative complications. Methods: A total of 359 patients undergoing major colorectal surgery between 2012 and 2015 were eligible for this study. Uni- and multivariate analyses were performed to identify risk factors for postoperative complications. Receiver operating characteristic curves were developed to examine the cutoff values and diagnostic accuracy of the CRP/albumin ratio and postoperative CRP levels. Results: Among all the patients, 139 (38.7%) were reported to have postoperative complications. The CRP/albumin ratio was an independent risk factor for complications (OR 4.413; 95% CI 2.463-7.906; P < 0.001), and the cutoff value was 2.2, which had a higher area under the curve compared to CRP on postoperative day 3 (AUC 0.779 vs 0.756). The CRP/albumin ratio also had a higher positive predictive value than CRP levels on postoperative day 3. Patients with CRP/albumin ≥ 2.2 suffered more postoperative complications (60.8% vs 18.6%, P < 0.001), longer postoperative stays (10 (4-71) vs 7 (3-78) days, P < 0.001), and increased surgical site infections (SSIs) (21.1% vs 4.8%, P < 0.001) than those with CRP/albumin <2.2. Conclusions: The ratio of C-reactive protein to albumin could help to identify patients who have a high probability of postoperative complications, and the ratio has higher diagnostic accuracy than C-reactive protein alone for postoperative complications in colorectal surgery.

High levels of immunoglobulin A (IgA)-coated bacteria may have a role in driving inflammatory bowel disease (IBD). We therefore investigated the effect of sodium butyrate on microbiota in IBD prone interleukin (IL)-10-/- mice. At 8 weeks of age, mice were allocated into three groups (n = 4/group): normal (C57BL/6), IL-10-/-, and IL-10-/- treated with sodium butyrate (100 mM). Severity of colitis, inflammatory cytokine and short-chain fatty acid (SCFA) concentration in proximal colon contents, the percentage of IgA-coated bacteria and microbiota composition by 16S ribosomal RNA assessment of stool were measured after 4 weeks of treatment. Sodium butyrate ameliorated histological colitis and decreased levels of tumor necrosis factor (TNF)-α and IL-6 in IL-10-/- mice compared with those without treatment. At the phylum level, a reduction in Bacteroidetes and an increase in Firmicutes in IL-10-/- mice treated with sodium butyrate were observed. Additionally, Prevotellaceae species were reduced in IL-10-/- mice treated with sodium butyrate as compared with those without treatment. The level of biodiversity was slightly increased and the amount of IgA-coated bacteria decreased in IL-10-/- mice treated with sodium butyrate compared with those without treatment. Our results indicate that sodium butyrate protects against colitis, possibly through modifying the gut microbiota, enriching biodiversity and reducing the amount of colitogenic IgA-coated bacteria in IL-10-/- mice.

Background: Neonatal health (NH) remains a major problem in many countries. Children dying before 28 days often suffer from conditions that are preventable or treatable with proven, cost-effective interventions. The knowledge gaps are no longer about what should be done, but to understand why guidelines including these interventions are not followed. Using a behaviour change framework, this study explores neonatal health guidelines use and the role of management in supporting effective usage in two rural settings in China and Vietnam. Methods: Semi-structured interviews with policy makers, health care managers and providers (n = 49) and focus group discussions with women, husbands and grandmothers who had experienced maternal and NH care services within the last year (n = 7) were conducted. Data were analysed using the framework approach. Results: Guidelines are not readily available at county, township and village levels in the study sites in China, whereas, in Vietnam, guidelines are available, accepted and being used at facility level. Improvements in implementation could be made in both settings. Factors influencing guidelines use common to both settings included: lack of equipment and supplies; shortage of staff with NH care experience; and guidelines not in line with patient practices. Factors specific to China included: poor guidelines dissemination; and disagreement with guidelines. There was limited community engagement in NH services in China, whereas in Vietnam, community members were actively involved in decision making and provision of services. Managers have an important role in supporting NH guidelines use through: ensuring guidelines are available; allocating appropriate resources; supporting and monitoring staff in their use; and engaging with local communities to promote effective practices. Conclusions: Engaging managers to support implementation is crucial. Management systems that provide the necessary resources, competent staff, and monitoring, regulatory and incentive frameworks as well as community engagement are needed to promote adoption of guidelines. Further research on how best to strengthen local level management so that they tailor interventions to support guideline use to their specific context is needed. This will ensure that proven interventions to address NH problems are used, and that countries move closer to achieving the new Sustainable Development Goal 3 target. [ABSTRACT FROM AUTHOR]

Background: Fecal microbiota transplantation (FMT) induces remission in ulcerative colitis (UC). However, the treatment effect of FMT diminishes over time. Maintaining the diversity of the gut flora for long periods may improve the effects of FMT in UC. Pectin, which can be fermented by gut microbiota into short-chain fatty acids, is postulated to shape the composition and maintain the balance of gut microbiota following transplantation. This study investigated whether pectin could enhance the effects of FMT in UC patients. Results: Three FMT patients and four FMTP patients achieved the primary outcome. The Mayo scores of the FMTP group were lower than those of the FMT group at weeks 4 and 12 (P = 0.042 and P = 0.042, respectively). There were no differences in the diversity of the gut flora between the two groups at weeks 4 and 12; however, the composition of the gut flora of the FMTP group was more similar than the FMT group to that of the donor at all-time points post-treatment. Conclusions: Pectin decreased the Mayo score by preserving the diversity of the gut flora following FMT for UC. [ABSTRACT FROM AUTHOR]

Background: Increases in health care utilization and costs, resulting from the rising prevalence of chronic conditions related to the aging population, is exacerbated by a high level of fragmentation that characterizes health care systems in China. There have been several pilot studies in China, aimed at system-level care coordination and its impact on the full integration of health care system, but little is known about their practical effects. Huangzhong County is one of the pilot study sites that introduced organizational integration (a dimension of integrated care) among health care institutions as a means to improve system-level care coordination. The purposes of this study are to examine the effect of organizational integration on system-level care coordination and to identify factors influencing care coordination and hence full integration of county health care systems in rural China. Methods: We chose Huangzhong and Hualong counties in Qinghai province as study sites, with only Huangzhong having implemented organizational integration. A mixed methods approach was used based on (1) document analysis and expert consultation to develop Best Practice intervention packages; (2) doctor questionnaires, identifying care coordination from the perspective of service provision. We measured service provision with gap index, overlap index and over-provision index, by comparing observed performance with Best Practice; (3) semi-structured interviews with Chiefs of Medicine in each institution to identify barriers to system-level care coordination. Results: Twenty-nine institutions (11 at county-level, 6 at township-level and 12 at village-level) were selected producing surveys with a total of 19 schizophrenia doctors, 23 diabetes doctors and 29 Chiefs of Medicine. There were more care discontinuities for both diabetes and schizophrenia in Huangzhong than in Hualong. Overall, all three index scores (measuring service gaps, overlaps and over-provision) showed similar tendencies for the two conditions. The gap indices of schizophrenia (> 5.10) were bigger for diabetes (< 2.60) in both counties. The over-provision indices of schizophrenia (> 3.25) were bigger than diabetes (< 1.80) in both counties. Overlap indices for the two conditions exceeded justified overlaps, especially for diabetes. Gap index scores for schizophrenia interventions at the township-level and over-provision index scores for diabetes interventions at both village- and township-level showed big differences between the two counties. Insufficient medical staff with appropriate competencies, lack of motivation for care coordination and related supportive policies as well as unconnected information system were identified as barriers to system-level care coordination in both counties. Conclusion: Findings demonstrate that organizational integration in Huangzhong has not achieved a higher level of care coordination at this stage. System-level care coordination is most problematic at village-level institutions in Hualong, but at county-level institutions in Huangzhong. These findings suggest that attention be given to other aspects of integration (e.g., clinical and service integration) to promote system-level care coordination and contribute to the full integration of health care system in the pilot county.

Synbiotic intake may efficiently restore the balance of gut microbiota and improve gastrointestinal functions. The aim of the study was to evaluate the efficacy of a synbiotic in patients with slow transit constipation. A total of 100 patients with slow transit constipation were randomized to receive either a synbiotic or placebo twice daily for 12 weeks. The primary efficacy endpoints were the clinical remission and improvement rates at weeks 4 and 12. Stool frequency and consistency, colonic transit time (CTT), evacuation and abdominal symptoms, patient assessment of constipation symptoms, gastrointestinal quality-of-life index scores, satisfaction scores, and adverse events were also monitored. The clinical remission rates reached 37.5% at week 4 and 45.8% at week 12 in the treatment group, compared to 13.3% at week 4 and 16.7% at week 12 in the placebo group (p < 0.01 for both comparisons). Over 12 weeks, 64.6% of the patients who received the synbiotic experienced clinical improvement, compared to 29.2% of the patients in the placebo group (p < 0.01). During the intervention period, patients who were treated with the synbiotic exhibited increased stool frequency, improved stool consistency, decreased CTT, and improved constipation-related symptoms. This randomized, placebo-controlled trial suggested that dietary supplementation with a synbiotic improved evacuation-parameters-associated symptoms and colonic motility in patients with slow transit constipation (STC).

MicroRNAs (miRNAs) have been shown to be important for the pathogenesis of Crohn's disease (CD). Exclusive enteral nutrition (EEN) is an effective therapy for inducing remission in CD. We aimed to investigate the alteration of miRNAs expression profile in the terminal ileal mucosa of CD patients before and after EEN. Twenty-five patients and ten healthy individuals were included. MiRNAs expression profile was firstly assessed using microarray technology and then validation was performed by qRT-PCR. The correlations between miRNAs and CD activity index (CDAI) score and serum C-reactive protein (CRP) level were also evaluated. Microarray analysis showed that mucosal miRNAs expression profile after EEN therapy was significantly changed compared with inflamed mucosa before treatment, and was most similar to the healthy one among all CD groups. Altered expressions of hsa-miR-192-5p, hsa-miR-423-3p, hsa-miR-99a-5p, hsa-miR-124-3p, hsa-miR-301a-5p, hsa-miR-495-5p, and hsa-let-7b-5p were confirmed by qRT-PCR. hsa-let-7b-5p was significantly correlated with serum CRP levels before and after EEN treatment (r = -0.518, p = 0.008, and r = -0.569, p = 0.003). Our study showed EEN induction therapy was associated with a trend for normalizing of the mucosal MiRNAs expression profile, and expression of mucosal hsa-let-7b-5p was correlated with serum CRP level in patients with CD.

Background: Clinical practice guidelines (CPGs) are formally developed statements that assist users to provide proper health care for a kind of disease and play a significant contribution in healthcare system. This study report the methodological quality of CPGs on constipation.Methods: The "Appraisal of Guidelines and Research and Evaluation" (AGREEII) instrument was developed to determine the quality of CPGs. A comprehensive search was developed using five databases and three guideline websites until/up to December, 2015. Four independent authors evaluated the methodological issues of the CPGs by the AGREEII instrument.Results: We identified 22 relevant guidelines on constipation from 1234 citations. The overall agreement among evaluators was 0.84 using the intra-class correlation coefficient. The mean AGREEII scores for the domains "scope and purpose" (51.77) and "rigor of development" (56.73) were moderate; afterward, three domains "stakeholder involvement" (32.23), "editorial independence" (29.59) and "applicability" (29.14) were low scores. The "clarity and presentation" (23.73) had the lowest scores.Conclusion: Although existing constipation guidelines may accurately reflect current clinical practices, many guidelines' methodological quality is low. Therefore, more emphasis and attentions should be taken to the development of high-quality guidelines. [ABSTRACT FROM AUTHOR]

Recently, numerous studies have shown that disruption of the mucus barrier plays an important role in the exacerbation of inflammatory bowel disease, particularly in ulcerative colitis. Alterations in the mucus barrier are well supported by published data and are widely accepted. The use of fluorescence in situ hybridization and Carnoy's fixation has revealed the importance of the mucus barrier in maintaining a mutualistic relationship between host and bacteria. Studies have raised the possibility that modulation of the mucus barrier may provide therapies for the disease, using agents such as short-chain fatty acids, prebiotics and probiotics. This review describes changes in the mucus barrier of patients with inflammatory bowel disease and in animal models of the disease. We also review the involvement of the mucus barrier in the exacerbation of the disease and explore the therapeutic potential of modifying the mucus barrier with short-chain fatty acids, prebiotics, probiotics, fatty acid synthase, H2S, neutrophil elastase inhibitor and phophatidyl choline.
