Effect of acute alcohol consumption on blunt bowel mesenteric injury: a retrospective analysis.

BACKGROUND: The effect of alcohol consumption on trauma remains controversial. The effects of alcohol on hemorrhage and peritonitis after blunt abdominal trauma have rarely been discussed. This study aimed to explore the effects of acute alcohol intoxication on the clinical characteristics, injury patterns, and outcomes in a surgical blunt bowel mesenteric injury (BBMI) cohort. METHODS: A retrospective data analysis was performed using trauma cases of patients who had been tested for alcohol and had surgically proven BBMI from a Trauma Registry System from 2009 to 2021. Patients were grouped according to their positive blood alcohol concentration (BAC; >0.5% vs. no BAC; less than 0.5% no BAC) upon arrival at the emergency department (ED). The injury characteristics, physiological parameters, and outcomes with respect to post-injury complications and mortality were assessed. RESULTS: In total, 142 patients with surgical BBMI were included. Of these, 116 and 26 patients were assigned to the BAC-negative and BAC-positive groups, respectively. The overall injury severity, injury pattern, and age were comparable between the groups. The patients in the BAC-positive group had a significantly lower systolic blood pressure (99 mmHg vs. 119 mmHg; p = 0.046), worse shock index (0.96 vs. 0.82; p = 0.048), and lower percentage and number of packed red blood cells transfused (34.6% vs. 57.8%; p = 0.032 and 0 U vs. 2 U; p = 0.031) than those in the BAC-negative group. Additionally, although not statistically significant, patients in the BAC-positive group had lower leukocyte counts (9,700 cells/mm3 vs. 11,600 cells/mm3; p = 0.165 ) at the ED. However, significantly reduced percentages of leukocytes ≥ 12,000 cells/mm3 (26.9% vs. 48.3%; p = 0.048) and ≥ 12,000 or ≤ 4,000 cells/mm3 (26.9% vs. 50.9%; p = 0.027) were observed in the BAC-positive group at the ED. Furthermore, the 30-day mortality rate did not show statistically significant differences, and there was a higher incidence of bowel-related mortality in the BAC-positive group (11.5% vs. 1.7%, p = 0.043). CONCLUSIONS: For patients with BBMI arriving alive to the hospital, acute alcohol consumption was associated with significantly worse hemodynamic parameters, interfered inflammation status, and higher bowel related mortality rate.

Biophysical Electrical and Mechanical Stimulations for Promoting Chondrogenesis of Stem Cells on PEDOT:PSS Conductive Polymer Scaffolds.

The investigation of the effects of electrical and mechanical stimulations on chondrogenesis in tissue engineering scaffolds is essential for realizing successful cartilage repair and regeneration. The aim of articular cartilage tissue engineering is to enhance the function of damaged or diseased articular cartilage, which has limited regenerative capacity. Studies have shown that electrical stimulation (ES) promotes mesenchymal stem cell (MSC) chondrogenesis, while mechanical stimulation (MS) enhances the chondrogenic differentiation capacity of MSCs. Therefore, understanding the impact of these stimuli on chondrogenesis is crucial for researchers to develop more effective tissue engineering strategies for cartilage repair and regeneration. This study focuses on the preparation of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) conductive polymer (CP) scaffolds using the freeze-drying method. The scaffolds were fabricated with varying concentrations (0, 1, 3, and 10 wt %) of (3-glycidyloxypropyl) trimethoxysilane (GOPS) as a crosslinker and an additive to tailor the scaffold properties. To gain a comprehensive understanding of the material characteristics and the phase aggregation phenomenon of PEDOT:PSS scaffolds, the researchers performed theoretical calculations of solubility parameters and surface energies of PSS, PSS-GOPS, and PEDOT polymers, as well as conducted material analyses. Additionally, the study investigated the potential of promoting chondrogenic differentiation of human adipose stem cells by applying external ES or MS on a PEDOT:PSS CP scaffold. Compared to the group without stimulation, the group that underwent stimulation exhibited significantly up-regulated expression levels of chondrogenic characteristic genes, such as SOX9 and COL2A1. Moreover, the immunofluorescence staining images exhibited a more vigorous fluorescence intensity of SOX9 and COL II proteins that was consistent with the trend of the gene expression results. In the MS experiment, the strain excitation exerted on the scaffold was simulated and transformed into stress. The simulated stress response showed that the peak gradually decreased with time and approached a constant value, with the negative value of stress representing the generation of tensile stress. This stress response quantification could aid researchers in determining specific MS conditions for various materials in tissue engineering, and the applied stress conditions could be further optimized. Overall, these findings are significant contributions to future research on cartilage repair and biophysical ES/MS in tissue engineering.

Laser Acupuncture Analgesia on Postpartum Low Back Pain: A Prospective Randomized Controlled Study.

BACKGROUND: Unresolved postpartum LBP may affect women...s physical and psychological health. AIM: To investigate the analgesic effects of laser acupuncture therapy (LAT) for postpartum LBP. METHOD: Postpartum women with LBP were recruited and randomly assigned to the intervention group or the control group from November 2017 to July 2018. The participants in the intervention group received LAT and standard care. The participants in the control group received only standard care. The primary outcome was the Visual Analogue Scale for LBP. Secondary outcomes were limitation of daily activities and physical activity; perceived stress scale; and salivary cortisol values. RESULTS: In all, 106 participants were recruited and assigned to the intervention group or the control group. As compared with the control group, the participants in the LAT group had significantly lower intensity of LBP (mean ± SD: 1.21 ± 0.99 vs 3.25 ± 1.14; p < .001), limitations of daily activities (mean ± SD: 3.17 ± 2.09 vs 10.40 ± 4.72; p < .001) and physical activity (mean ± SD: 3.04 ± 2.17 vs 9.79 ± 4.71; p < .001), perceived stress (mean ± SD: 26.13 ± 3.97 vs 28.85 ± 4.26; p = .001), and salivary cortisol levels (mean ± SD: 0.194 ± 0.131 vs 0.280 ± 0.234; p = .02) post-intervention. CONCLUSIONS: For postpartum LBP, LAT combined with standard care had greater analgesic efficacy, lower perceived stress, lower limitations of daily activities and physical activity, and lower salivary cortisol levels than standard care alone.

Sensitive Detection of Sweat Cortisol Using an Organic Electrochemical Transistor Featuring Nanostructured Poly(3,4-Ethylenedioxythiophene) Derivatives in the Channel Layer.

In this study, we examined the influence of functionalized poly(3,4-ethylenedioxythiophene) (PEDOT) nanostructures decorated on the channel layer of an organic electrochemical transistor (OECT) for the detection of sweat cortisol, an adrenocorticosteroid stress hormone. The OECT device featured a bilayer channel confined by a PEDOT:polystyrenesulfonate (PSS) underlayer and a nanostructure-decorated upper layer engineered from the monomers EDOT-COOH and EDOT-EG3 through template-free electrochemical polymerization. This molecular design allowed antibody conjugation using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide/N-hydroxysulfosuccinimide coupling through the carboxylic acid side chain, with EDOT-EG3 known to minimize nonspecific binding of biomolecules. We also engineered an OECT device having a channel area without any nanostructures to gain insight into the effect of the nanostructures on cortisol sensing. Our new nanostructure-embedded OECT device facilitated real-time detection of cortisol at concentrations ranging from 1 fg/mL to 1 µg/mL with a detection limit of 0.0088 fg/mL with good linearity (R2 = 0.9566), in addition to excellent selectivity toward cortisol among other structurally similar interfering compounds and high stability and reproducibility. With its rapid response for the detection of 100 ng/mL cortisol-spiked artificial sweat, this nanostructure-decorated OECT device has potential clinical practicality and utility in wearable sensors for future healthcare applications.

Pain Experiences and Coping Strategies in Rural Older Adults With Chronic Musculoskeletal Pain in Mountainous Areas of Taiwan.

BACKGROUND: Although rural communities are home to a higher proportion of older residents, they provide fewer healthcare services than do urban core communities. Chronic musculoskeletal (MSK) pain is often associated with reduced daily activity and quality of life in older adults, particularly those in rural areas. AIMS: This study investigated the pain experiences and coping strategies in rural older adults with MSK pain in Taiwan. METHODS: A structured questionnaire was used to collect data from rural older adults with chronic MSK pain in mountainous areas of Taiwan. RESULTS: In total, 55 rural older adults were enrolled in this study. The most common pain sites were the low back and knees. The main cause of pain was osteoarthritis. Three quarters of the participants suffered from moderate to severe chronic MSK pain on average. The results revealed that behavioral strategies were used more often than cognitive strategies. Regarding behavioral strategies, the most common non-pharmacologic and pharmacologic pain coping strategies were to rest and to take Chinese medicine, respectively. The most common cognitive strategy for pain coping was to talk to others. CONCLUSIONS: The findings suggested that pain management for chronic MSK pain in rural older adults was inadequate in mountainous areas of Taiwan. Most rural older adults used multiple coping strategies to deal with their pain, and behavioral strategies were favored over cognitive strategies.

Discovery and Biocatalytic Application of a PLP-Dependent Amino Acid γ-Substitution Enzyme That Catalyzes C-C Bond Formation.

Pyridoxal phosphate (PLP)-dependent enzymes can catalyze transformations of l-amino acids at α, ß, and γ positions. These enzymes are frequently involved in the biosynthesis of nonproteinogenic amino acids as building blocks of natural products and are attractive biocatalysts. Here, we report the discovery of a two-step enzymatic synthesis of (2S,6S)-6-methyl pipecolate 1, from the biosynthetic pathway of citrinadin. The key enzyme CndF is PLP-dependent and catalyzes the synthesis of (S)-2-amino-6-oxoheptanoate 3 that is in equilibrium with the cyclic Schiff base. The second enzyme CndE is a stereoselective imine reductase that gives 1. Biochemical characterization of CndF showed this enzyme performs γ-elimination of O-acetyl-l-homoserine to generate the vinylglycine ketimine, which is subjected to nucleophilic attack by acetoacetate to form the new Cγ-Cδ bond in 3 and complete the γ-substitution reaction. CndF displays promiscuity toward different ß-keto carboxylate and esters. With use of an Aspergillus strain expressing CndF and CndE, feeding various alkyl-ß-keto esters led to the biosynthesis of 6-substituted l-pipecolates. The discovery of CndF expands the repertoire of reactions that can be catalyzed by PLP-dependent enzymes.

Multiparameter Kinetic Analysis for Covalent Fragment Optimization by Using Quantitative Irreversible Tethering (qIT).

Chemical probes that covalently modify cysteine residues in a protein-specific manner are valuable tools for biological investigations. Covalent fragments are increasingly implemented as probe starting points, but the complex relationship between fragment structure and binding kinetics makes covalent fragment optimization uniquely challenging. We describe a new technique in covalent probe discovery that enables data-driven optimization of covalent fragment potency and selectivity. This platform extends beyond the existing repertoire of methods for identifying covalent fragment hits by facilitating rapid multiparameter kinetic analysis of covalent structure-activity relationships through the simultaneous determination of Ki , kinact and intrinsic reactivity. By applying this approach to develop novel probes against electrophile-sensitive kinases, we showcase the utility of the platform in hit identification and highlight how multiparameter kinetic analysis enabled a successful fragment-merging strategy.

A Narrative Review of Complementary Nutritional Supplements for Chemotherapy-induced Peripheral Neuropathy.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common troublesome side effect and affects long-term activities of daily living. This neuropathic disorder is still difficult to treat with current clinical treatments. The aim of this study was to investigate and offer an updated perspective of complementary therapies for CIPN. METHODS: This review included current databases, including PubMed, Embase, the Cochrane Database, Google Scholar, and Ovid Medline, published up to May 2019 in the English language, to summarize the role of nutrient supplements in CIPN, based on evidence from both animal and clinical studies. RESULTS: A total of 58 studies were included in this review. There were 19 preclinical studies that reported mechanisms of effects and 31 clinical studies corroborated preclinical findings, including 22 randomized controlled trials and 3085 patients with CIPN. Interventions included vitamin E, vitamin B complex, glutamine, acetyl-L-carnitine, alpha lipoic acid, glutathione, omega-3 fatty acids, and calcium/magnesium (Ca2+/Mg2+). The administration of various nutrients remains inconsistent, and limited evidence of effective ones for treating CIPN is available. However, glutamine and omega-3 fatty acids present potential as treatment options for CIPN. The evidence on vitamin E and vitamin B complex is inconclusive, and some forms of vitamin B, such as B6 or B12, await confirmation of their potential to offer protection from CIPN. Less robust evidence was found for nutrients such as acetyl-L-carnitine, α-Lipoic acid, glutathione, and Ca2+/Mg2+ for CIPN. CONCLUSION: Nutritional therapists seem to recommend nutrient supplements as potential anti-inflammatory and neuroprotective agents for both the prevention and management of CIPN. An understanding of this evolving literature is useful in exploring these therapies with patients who are considering using them. However, their effects against CIPN are still controversial due to the undetermined neuropathic mechanisms of different antineoplastic agents and complex drug interactions. Further research on these agents is warranted.

Correlation between Glyoxal-Induced DNA Cross-Links and Hemoglobin Modifications in Human Blood Measured by Mass Spectrometry.

Glyoxal is an oxoaldehyde generated from the degradation of glucose-protein conjugates and from lipid peroxidation in foods and in vivo, and it is also present in the environment (e.g., cigarette smoke). The major endogenous source of glyoxal is glucose autoxidation, and the glyoxal concentrations in plasma are higher in diabetic patients than in nondiabetics. Glyoxal reacts with biomolecules forming covalently modified DNA and protein adducts. We previously developed sensitive and specific assays based on nanoflow liquid chromatography-nanospray ionization tandem mass spectrometry (nanoLC-NSI/MS/MS) for quantification of DNA cross-linked adducts (dG-gx-dC and dG-gx-dA) and for hemoglobin adducts derived from glyoxal. In this study, we isolated and analyzed both leukocyte DNA and hemoglobin from the blood of diabetic patients and compared the adduct levels with those from nondiabetic subjects using the modified assays. The results indicated that the extents of glyoxal-induced hemoglobin modifications on α-Lys-11, α-Arg-92, ß-Lys-17, and ß-Lys-66 were statistically higher in diabetic patients than nondiabetics and they correlated with HbA1c significantly. Moreover, the levels of dG-gx-dC in leukocyte DNA correlated positively with the extents of globin modification at α-Lys-11 and ß-Lys-17, while levels of dG-gx-dA correlated with those at α-Lys-11 and α-Arg-92 in nonsmoking subjects. Comparing the levels and the correlation coefficients of these hemoglobin and DNA adducts including or excluding smokers, it appears that smoking is not a major contributor to glyoxal-induced adduction of hemoglobin and leukocyte DNA. To the best of our knowledge, this is one of the few reports of positive correlation between DNA and protein adducts of the same compound (glyoxal) in the blood from the same subjects. Because of the high abundance of hemoglobin in blood, the results indicate that quantification of glyoxal-modified peptides in hemoglobin might serve as a dosimetry for glyoxal and a practical surrogate biomarker for assessing glyoxal-induced DNA damage and its prevention.

Effect of acupressure on constipation in patients with advanced cancer.

PURPOSE: Constipation is a common and distressing symptom for patients with advanced cancer. Few reports have focused on the symptoms of constipation in patients with advanced cancer. The aim of this study was to investigate the effect of a short-term acupressure intervention on patients with advanced cancer. METHODS: This study used a non-randomized, pre-post study design to assess the effect of acupressure intervention. A total of 30 patients with advanced cancer were recruited from the hospice unit of a medical center in southern Taiwan. In addition to routine care, patients in the intervention group received an 8-min acupressure treatment daily for 3 consecutive days. Three acupoints were used in this study: Zhongwan (CV12), Guanyuan (CV4), and Tianshu (ST25). Analysis of covariance was used to compare the differences in symptoms of constipation between the two groups, adjusted for baseline values. Effect sizes were calculated using partial eta squared (η2). RESULTS: Significant improvements in symptoms of constipation (partial η2 = 0.40, p < 0.001 for straining during defecation; partial η2 = 0.30, p = 0.002 for hard stools; partial η2 = 0.42, p < 0.001 for sensation of incomplete evacuation; and partial η2 = 0.29, p = 0.002 for sensation of anorectal obstruction), Bristol stool form scale scores (partial η2 = 0.40, p < 0.001), comfort levels during defecation (partial η2 = 0.82, p < 0.001), and colonic motility (partial η2 = 0.85, p < 0.001) were observed in patients receiving acupressure intervention compared with the controls. CONCLUSIONS: Findings from this study indicated that short-term acupressure was effective in alleviating symptoms of constipation among patients with advanced cancer. Further, randomized controlled trials are warranted to confirm the results.

Chiral Separation of Cytotoxic Flavan Derivatives from Daphne giraldii.

Twelve new flavan derivatives including four pairs of enantiomers, daphnegiralins A1-A4 (1) and daphnegiralins B1-B4 (2), and two pairs of epimers, daphnegiralins C1/C2 (3) and daphnegiralins D1/D2 (4), were isolated from the stem bark and roots of Daphne giraldii. Their structures were elucidated using spectroscopic analyses, computational approaches, and chemical methods. Separation of the enantiomeric mixtures (1a, 1b, 2a, and 2b) was achieved using chiral HPLC. The compounds were evaluated against a small panel of human cancer cell lines, and 1b-2, 2a, and 2b were cytotoxic against Hep3B human hepatoma cells.

Comparable efficacy and safety for bicuspid aortic valve stenosis patients undergoing transcatheter aortic valve replacement with balloon-expandable or self-expanding valves using Wei's sizing method.

BACKGROUND: The present study aimed to investigate whether proper sizing can improve the procedural and clinical outcomes of transcatheter aortic valve replacement (TAVR) with new-generation self-expanding valves (SEVs) and balloon-expandable valves (BEVs) for treating bicuspid aortic stenosis (BAS). METHODS: We retrospectively evaluated consecutive patients who underwent TAVR with Sapien 3 valves (Edwards Lifesciences, Irvine, CA) or Evolut R/PRO valves (Medtronic, Minneapolis, MN) for severe BAS from 2017 to 2022. The primary endpoints were device success rate and major adverse cardiac and cerebral events (MACCEs), including mortality, non-fatal myocardial infarction or disabling stroke, transcatheter heart valve failure, or clinically relevant valve thrombosis during follow-up. Our team employed a complementary approach of supra-annular sizing in addition to the conventional annular sizing method (Wei's method) to guide the TAVR procedures. RESULTS: We recruited a total of 75 consecutive patients, of whom 43 (57%) were treated with BEVs from October 2017 to June 2021, and 32 (43%) were treated with SEVs from July 2021 to December 2022. Device success was similar between the BEV and SEV groups (93% vs. 94%; p > 0.99), and no cases of annular rupture occurred in either group. Similar rates of moderate-to-severe paravalvular leak were observed in the BEV and SEV groups (5% vs. 6%, p > 0.99). At a median follow-up of 464 days, the MACCE rates were comparable between the two groups. In multivariate analysis, the presence of previous percutaneous coronary interventions (hazard ratio: 5.43; p = 0.039) and New York Heart Association functional class III/IV heart failure at 30 days of follow-up after TAVR (hazard ratio: 9.90; p = 0.037) were independently associated with long-term MACCEs. CONCLUSION: Our results demonstrated comparable efficacy and safety for BAS patients undergoing TAVR using either BEVs or SEVs when using Wei's sizing method.

Impact of Pelvic Fracture on Patients with Blunt Bowel Mesenteric Injury: Is Immediate Laparotomy Warranted?

The management of blunt abdominopelvic trauma with combined hemoperitoneum and pelvic fractures is challenging for trauma surgeons. Although angioembolization can achieve hemostasis in most visceral organ injuries and pelvic fractures after blunt abdominal trauma, it cannot effectively control hemorrhage in patients with blunt bowel mesenteric injury (BBMI). This study aimed to determine the risk factors associated with hemodynamically unstable patients with BBMI and to test the hypothesis that pelvic fracture is an independent risk factor for patients with unstable BBMI and concomitant pelvic fracture to guide the therapeutic sequence for difficult-to-manage patients. This retrospective study reviewed the data of hospitalized patients with trauma between 2009 and 2021 and included 158 adult patients with surgically proven BBMI. The patients were divided on the basis of the presence of a shock episode before emergency laparotomy. The shock group included 44.3% of all patients in the study (n = 70). Clinical injury severity and prognosis for patients in the shock group were poorer than those for patients in the non-shock group, and more invasive treatments and transfusions were performed for patients in the shock group than for those in the non-shock group. Pelvic fractures were more frequently associated with the shock group than with the non-shock group (21.4% vs. 5.7%; p = 0.003). In multivariate analysis, the presence of intracerebral hemorrhage (odds ratio [OR] = 10.87, 95% confidence intervals [CIs]: 1.70-69.75) and rib fracture (OR = 5.94, 95% CIs = 1.06-33.45) was identified as an independent predictor of shock, whereas the effect of pelvic fracture did not achieve statistical significance (OR = 2.94, 95% CIs = 0.66-13.13) after adjusting for confounding factors. For patients with BBMI, outcomes need to be improved during early diagnosis, and treatments should be expeditiously performed on the basis of the rapid identification of unstable hemodynamic status. Our results support the recommendation of emergency laparotomy in unstable patients with concomitant pelvic fractures, followed by damage control TAE if needed.

Analgesic Effect of Low-Level Laser Therapy before Heel Lance for Pain Management in Healthy Term Neonates: A Randomized Controlled Trial.

Currently, the prevention, assessment, and management of procedural pain in neonates continues to challenge clinicians and researchers. Objective. To investigate the analgesic effect of low-level laser therapy (LLLT) during heel lance compared to breast milk (BM) feeding in healthy term neonates. In this randomized controlled trial, healthy term neonates who underwent heel lance were randomly assigned to an LLLT or a BM group. The LLLT group received laser therapy to the heel lance site for 20 s before heel lance. The BM group received 5 mL expressed BM via a syringe before heel lance. The primary outcomes were behavioral responses. The secondary outcomes were physiological responses and levels of salivary cortisol and α-amylase. A total of 125 neonates were included, of whom 55 in the LLLT group and 59 in the BM group completed the study. There were no significant differences in latency to first cry and cry duration between the two groups. The squeeze time was significantly shorter in the LLLT group than in the BM group (p = 0.047). There were no significant differences in pain scores, heart rate, respiratory rate, oxygen saturation, and blood pressure before and after heel lance between the two groups. There were no significant differences in salivary cortisol and α-amylase levels in the LLLT group before and after heel lance; however, the differences were significant in the BM group. These findings suggest that the analgesic effect of LLLT is similar to that of BM during heel lance in healthy term neonates. LLLT has potential as an analgesic treatment.

A Retrospective Cohort Study on the Clinical Characteristics of Patients with Surgical Blunt Bowel and/or Mesenteric Injuries among Motorcyclists and Car Occupants.

(1) Background: Surgical blunt bowel and/or mesenteric injuries (BBMIs) are rare but challenging for trauma surgeons. Surgical BBMI is associated with specific injury mechanisms, such as direct compression by the handlebar in motorcycle accidents or rapid acceleration and deceleration of the impact forces associated with seatbelt injuries in motor vehicle collisions. However, the discussions on the implications of BBMI and the mechanisms of road traffic accidents remain scarce. This retrospective study assessed the clinical and injury characteristics of surgically proven BBMI among motorcyclists and car occupants based on trauma-registered data obtained from a level I trauma center in Taiwan. (2) Methods: Medical data of 72 motorcyclists and 38 car occupants who had surgical BBMI between January 2009 and December 2020 were reviewed. Patient characteristics, injuries, and outcomes in both groups were compared and analyzed. (3) Results: Motorcyclists with surgical BBMI had a significantly higher Injury Severity Score (median [Q1-Q3], 18 (9-27) vs. 16 (9-18), p = 0.044) and lower Glasgow Coma Scale score (15 (11-15) vs. 15 (15-15), p = 0.034]) than car occupants. Motorcyclists with surgical BBMI had a higher incidence of pelvic fractures (18.1% vs. 2.6%, p = 0.032) and upper limb fractures (23.6% vs. 7.9%, p = 0.042) and a significantly higher rate of chest tube insertion than car occupants (29.2% vs. 10.5%, p = 0.027). However, there were no significant differences in the outcomes of morbidity and mortality between motorcyclists and car occupants with surgical BBMI. (4) Conclusions: This study demonstrated there were no significant differences in outcomes between motorcyclists and car occupants with surgical BBMI. However, motorcyclists with surgical BBMI were injured more severely, along with injuries to the head/neck and extremities, than car occupants.

Functional Connectivity, Physical Activity, and Neurocognitive Performances in Patients with Vascular Cognitive Impairment, No Dementia.

BACKGROUND: Vascular Cognitive Impairment, No Dementia (VCIND) is a key stage at which early intervention will delay or prevent dementia. The pathophysiology of VCIND posits that a lesion in a single location in the brain has the ability to disrupt brain networks, and the subsequent abnormal Functional Connectivity (FC) of brain networks leads to deficits in corresponding neurobehavioral domains. In this study, we tested the hypothesis that disrupted anterior cingulate cortex and striatal networks mediated the effects of Physical Activity (PA) on neurobehavioral function. METHODS: In 27 patients with VCIND, FC within the brain networks and neurobehavioral dysfunction were assessed. The relationship between the cognitive scores, FC, and PA was studied. The Fitbit Charge 2 was used to measure step counts, distance, and calories burned. In patients with VCIND, a cross-sectional Spearman's correlation to analyze the relationship among patient-level measures of PA, cognitive function scores, and FC strength within the brain networks. RESULTS: Average step counts and average distance were associated with Trail Making Test B (TMB) time to completion (seconds) and Instrumental Activities of Daily Living (IADL) score (P < 0.05). The average calories burned were associated with IADL score (P = 0.009). The FC within the brain networks anchored by left caudal Anterior Cingulate Cortex (ACC) seeds (x= -5, y= 0, z= 36) and (x= -5, y= -10, z= 47) were positively correlated with average step counts and average distance, were negatively correlated with TMB time to completion (seconds), and were positively correlated with IADL score (P < 0.05). The FC within the brain networks anchored by left subgenual ACC seed (x= -5, y= 25, z= -10) were negatively correlated with average step counts and average distance were positively correlated with TMB time to completion (seconds), and were negatively correlated with IADL score (P < 0.05). The FC within the striatal networks was positively correlated with average calories burned and IADL score (P < 0.05). CONCLUSION: FC within the brain networks anchored by caudal ACC seeds was positively correlated with more average step counts/average distance and better IADL score; negatively correlated with longer TMB time to completion (seconds), whereas FC of subgenual ACC seed was negatively correlated with the same parameters. FC within the brain networks anchored by putamen rather than caudate or pallidum was positively correlated with average calories burned and IADL score.

Case Report: First Case of Non-restrictive Ventricular Septal Defect With Congestive Heart Failure in a Chinese Han Male Infant Carrying a Class II Chromosome 17p13.3 Microduplication.

Chromosome 17p13.3 microduplication syndrome is considered a multisystem disorder that results in a wide variety of clinical manifestations including dysmorphic facial characteristics, brain structural malformations, developmental restriction, growth restriction, and neurocognitive disorders. The two major classes of chromosome 17p13.3 microduplication, which have different clinical presentations, are associated with specific genetic regions. Among the various known phenotypes, scattered cases with congenital heart disease (CHD) have been reported for both classes of chromosome 17p13.3 microduplication syndrome. Unfortunately, there is insufficient understanding of the correlation between chromosome anomaly induced alterations in gene expression and aberrant cardiac development, and thus early diagnosis of CHD among patients with chromosome 17p13.3 microduplication is difficult without routine prenatal cardiac assessment. One such congenital heart anomalies known to affect a substantial number of newborns worldwide is ventricular septal defect (VSD), which has been found in 17p13.3 microduplication carriers, and seems to sometimes undergo spontaneous closure. We report an unprecedented case of moderate sized perimembranous-outlet VSD and congestive heart failure (CHF) in a Chinese Han male infant with a class II chromosome 17p13.3 microduplication. Despite the fact that cytogenic testing and fetal echocardiography confirmed a 249-Kb chromosome duplication within 17p13.3 that encompassed the PAFAH1B1 gene and showed the presence of VSD during prenatal period, this patient still developed a range of symptoms including sustained prolonged feeding, dyspnea, diaphoresis and retarded growth. A physical examination indicated hepatomegaly and a grade III/VI pan-systolic murmur along the left upper sternal border. Laboratory testing showed a high serum pro-B-type natriuretic peptide (pro-BNP). Imaging studies revealed cardiomegaly and a persistent VSD with related pulmonary stenosis. Since the clinical findings were compatible with CHF, we provided mainline treatment with digoxin, captopril, and furosemide, as well as fluid restriction. Despite sustained poor weight gain, the feeding behavior and the respiratory conditions of the patient improved gradually. This case report and literature review suggest that patients carrying chromosome 17p13.3 microduplication who have VSD may have an increased risk of developing CHF as young infants and hence a comprehensive cardiac evaluation is warranted to allow the early diagnosis and management of any severe heart anomalies.

Laser meridian massage decreased craving in men with opioid use disorder on methadone maintenance treatment.

BACKGROUND: The incidence of opioid use disorder (OUD) is increasing worldwide, and the opioid-related overdose crisis is currently a major global challenge. This study investigated the effects of adjuvant laser meridian massage (LMM) in men with OUD undergoing methadone maintenance treatment (MMT). METHODS: A case-controlled study was conducted from February 2019 to April 2020. Fourteen men with OUD on MMT were enrolled from an addiction treatment center as an experimental group. An age-matched control group comprising 13 men was also enrolled. The experimental group received LMM on the back, including over the Bladder meridian and Governor Vessel, three times weekly for 4 weeks. The control group received only MMT. Urinary morphine levels, patients' self-reports of the number of episodes or days of heroin use, and visual analog scale scores for heroin craving/refusal to use heroin during the previous week were evaluated. Quality of life was reported using the Short Form (SF)-12v2. RESULTS: The experimental group showed a significant decrease in heroin use (p < 0.05), whereas the control group showed a significant increase in heroin craving (p < 0.05). The SF-12v2 Health Survey revealed a significant improvement in physical health in the experimental group (P < 0.05). CONCLUSION: The results of this study suggest that laser meridian massage can be considered a safe, well-tolerated, and potentially useful adjuvant intervention for opioid use disorder.

Chinese Herbal Medicine Reduces the Risk of Heart Failure in Hypertensive Patients: A Nationwide, Retrospective, Cohort Study.

Background: Hypertension (HTN) is the leading preventable risk factor for cardiovascular disease worldwide. Patients with HTN are at higher risk for heart failure (HF). The currently available therapeutic approaches for HTN do not always optimally control blood pressure or are not suitable for hypertensive patients who have a higher number of comorbidities. This study aimed to determine whether Chinese herbal medicine (CMH)-based interventions could reduce the risk of HF in hypertensive patients. Methods: This retrospective study randomly selected 2 million enrollees from the National Health Insurance Research Database and identified 507,608 patients who were newly diagnosed with HTN in 2000-2017. After 1:1 frequency-matching by age, sex, index year, income, urbanization, duration of HTN, comorbidities and antihypertensive medications, we selected 8,912 eligible patients in each group. During 16 years of follow-up, 380 CHM users and 426 CHM non-users developed HF, representing incidence rates of 6.29 and 7.43 per 1,000 person-years, respectively. Results: CHM users had significantly lower HF risk compared with CHM non-users (adjusted HR = 0.85, 95% CI 0.74-0.98). The markedly predominant effect was observed in those receiving CHM products for more than 180 days (adjusted HR = 0.65). The frequently prescribed formula, Jia-Wei-Xiao-Yao-San, and the single herbs Ge Gen, Huang Qi, Du Zhong, Huang Qin, and Chuan Xiong were significantly associated with lower risk of HF. Conclusions: This population-based study revealed decreased HF risk in hypertensive patients with CHM use. These findings may provide a reference for HF prevention strategies and support the integration of CHM into clinical intervention programs that provide a favorable prognosis for hypertensive patients.
