Essential Tremor and Parkinson’s Disease: Exploring the Relationship

Background There is longstanding controversy surrounding the possible link between essential tremor (ET) and Parkinson’s disease (PD). Inconsistent and unreliable diagnostic criteria may in part account for some of the difficulties in defining the relationship between these two common movement disorders. Methods References for this systematic review were identified using PubMed with the search terms “essential tremor” AND “Parkinson’s disease” with articles published in English between 1960 and September 2018 included. Results In this review we provide evidence that some patients diagnosed with ET have an increased risk of developing PD years or decades after onset of action tremor. There are several still unresolved questions about the link between the two disorders including lack of verifiable diagnostic criteria for the two disorders and marked overlap in phenomenology. Here we review clinical, epidemiologic, imaging, pathologic, and genetic studies that address the ET–PD relationship. Several lines of evidence support the association between ET and PD, including overlapping motor and non-motor features, relatively high prevalence of rapid eye movement sleep behavior disorder (26–43%) in ET patients, increased prevalence of PD in patients with longstanding antecedent ET, increased prevalence of ET in family members of patients with PD, and the presence of Lewy bodies in the brains of some ET patients (15–24%). Discussion There is a substantial body of evidence supporting the association between ET and PD within at least a subset of patients, although the nature and possible pathogenic mechanisms of the relationship are not well understood.
Evaluation of the accuracy of molecular assays targeting the mutation A2059G for detecting high-level azithromycin resistance in Neisseria gonorrhoeae: a systematic review and meta-analysis

Background Neisseria gonorrhoeae resistance to azithromycin has become a significant public health concern globally, and high-level azithromycin-resistant (HL-AzmR) isolates have emerged frequently. However, high-level azithromycin resistance is considered to be caused by mutated alleles of 23S rRNA gene at position 2059, and identification of HL-AzmR isolates mainly relies on agar dilution method or E-test method. This study aimed to assess the accuracy of the molecular assays targeting the mutation A2059G for identifying HL-AzmR isolates and thereby determine the association between the mutation and high-level azithromycin resistance. Methods Two researchers independently searched six databases to identify studies published from the launch of each database to October 15, 2017. The fixed effects model was used to estimate the pooled sensitivity rate, specificity rate, positive predictive value (PPV), and negative predictive value (NPV). Summary receiver operating characteristic curves were generated, and the area under the curve (AUC) was determined to estimate the overall performance of the assays. The Deeks' test was conducted to evaluate potential publication bias. Results Ten relevant studies were included in the meta-analysis to assess the synthetic accuracy of the molecular assays. The molecular assays had the synthetic sensitivity rate of 97.8% and the synthetic specificity rate of 99.1%. And the aggregated PPV and NPV were 96.4% and 99.5%, respectively. AUC was 0.99, suggesting a close relation existing between the mutation A2059G and high-level azithromycin resistance. This indicated that the molecular assays targeting the mutation A2059G have relatively high overall accuracy for identifying HL-AzmR N. gonor-rhoeae isolates. Publication bias was statistically significant. Conclusion The mutation A2059G is the critical factor causing high-level azithromycin resistance. Hence, molecular methods are recommended to be put into clinical practice by commercialization, which will assist clinicians to prescribe more precisely.
Effect of local anesthesia (with lidocaine vs bupivacaine) on cognitive function in patients undergoing elective cataract surgery

Purpose Postoperative cognitive dysfunction has gained much attention over the last years. Multiple clinical trials have attempted to differentiate the effect of local vs general anesthesia on postoperative cognitive function. The aim of this work was to study the effect of local anesthesia with lidocaine vs bupivacaine on cognitive function Patients and methods This was a prospective randomized trial carried out on 61 patients undergoing elective cataract surgery by phacoemulsification under local anesthesia. Twenty-eight patients received lidocaine 2% and 33 patients received bupivacaine 0.5%. Cognitive assessment for all patients was done preoperatively and 1 week postoperatively using paired associate learning test (PALT) and category verbal fluency (VF) test (animal category). Results Regarding cognitive assessment of patients in lidocaine group, there was a statistically significant difference between the mean value of preoperative PALT and postoperative PALT (P-value =0.004), and between the mean value of preoperative VF and postoperative VF (P-value =0.002). As for bupivacaine group, there was a statistically significant difference between the mean value of preoperative PALT and postoperative PALT (P-value =0.021), and between the mean value of preoperative VF and postoperative VF (P-value =0.037). On comparing lidocaine and bupivacaine groups in pre and postoperative PALT & VF scores, there was no statistically significant difference between both groups Conclusion Both lidocaine and bupivacaine caused postoperative cognitive impairment. Lidocaine was found to have a worse effect on cognitive function than bupivacaine, but the difference was not statistically significant.
Utility of power Doppler ultrasonography for detecting forefoot bursae in early rheumatoid arthritis

Rationale: Power Doppler ultrasonography (PDUS) in musculoskeletal ultrasound (MSUS) is a sensitive and reliable method for the assessment of rheumatoid arthritis (RA). The association between ultrasound-detectable forefoot bursae and the development of RA has gained attention. However, a few studies have evaluated the utility of PDUS for examining forefoot bursae in early RA. We report the case of an RA patient who developed reduced foot mobility and had detectable intermetatarsal bursitis with remarkable power Doppler (PD) signals in MSUS at the onset of RA. Patient concerns: A 40-year-old Japanese woman diagnosed with palindromic rheumatism visited our department due to sustained forefoot pain and difficulty walking. The levels of both rheumatoid factor (RF) and anticitrullinated protein antibody (ACPA) were high. She had opening toes with swelling in metatarsophalangeal (MTP) joints. PDUS showed intermetatarsal bursitis with mild MTP synovitis. Diagnoses: We diagnosed RA by comprehensive judgment based on the 2010 American College of Rheumatology and European League Against Rheumatism classification criteria for RA. Interventions: We administered 6.0 mg/wk of methotrexate (MTX) and 2.0 mg/d of prednisolone (PSL) followed by an increase of MTX to 10 mg/wk. Outcomes: After those treatments, the patient's symptoms showed improvement. As of this writing, the patient's remission has been maintained for >2 months. Lessons: Her case suggests that PDUS is useful for the detection of forefoot bursitis, and the detection of forefoot bursitis by PDUS may provide the opportunity to make an early diagnosis of RA.
Additional benefits of GeneXpert MTB/RIF assay for the detection of pulmonary tuberculosis patients with prior exposure to fluoroquinolones

Background We performed a prospective study to investigate the association between pre-diagnosis exposure to fluoroquinolone (FQ) and laboratory testing results among tuberculosis (TB) patients. Patients and methods Each TB-suspected patient provided sputum specimen for mycobacteria growth indicator tube (MGIT) culture and GeneXpert among pulmonary TB patients. Confirmed TB patients and clinically diagnosed TB patients were further enrolled in the final analysis. Results A total of 661 TB patients were included in the final analysis. The distribution of rural TB patients in the FQ-exposed group was significantly higher than that of urban TB patients (P=0.02). GeneXpert showed significantly better positive rate than MGIT technology for TB cases with prior FQ exposure (30.6% for GeneXpert vs 20.1% for MGIT, P=0.01). The positive rate of GeneXpert was significantly higher than that of MGIT for 7-13 days (P=0.04) and ≥14 days FQ exposure (P=0.01) groups, respectively. We also found that the positive rate of MGIT was significantly decreased from 31.5% for <7 days levofloxacin (LFX) exposure group to 9.4% for ≥14 days LFX exposure group (P=0.01), whereas the positive rate of MGIT displayed significant decrease after 7-13 days exposure to moxifloxacin (P=0.04). Conclusion In conclusion, our data demonstrate that TB patients prior to sputum collection are prone to yield negative culture results. GeneXpert could bring additional benefits for the detection of pulmonary TB patients with prior exposure to FQs. In addition, the exposure to moxifloxacin affected mycobacterial culture at an earlier stage compared with LFX.
Biodegradable and pH Sensitive Peptide Based Hydrogel as Controlled Release System for Antibacterial Wound Dressing Application

The stimuli-sensitive and biodegradable hydrogels are promising biomaterials as controlled drug delivery systems for diverse biomedical applications. In this study, we construct hybrid hydrogels combined with peptide-based bis-acrylate and acrylic acid (AAc). The peptide-based bis-acrylate/AAc hybrid hydrogel displays an interconnected and porous structure by scanning electron microscopy (SEM) observation and exhibits pH-dependent swelling property. The biodegradation of hybrid hydrogels was characterized by SEM and weight loss, and the results showed the hydrogels have a good enzymatic biodegradation property. The mechanical and cytotoxicity properties of the hydrogels were also tested. Besides, triclosan was preloaded during the hydrogel formation for drug release and antibacterial studies. In summary, the peptide-based bis-acrylate/AAc hydrogel with stimuli sensitivity and biodegradable property may be excellent candidates as drug delivery systems for antibacterial wound dressing application.
Mesenteric panniculitis: comparison of computed tomography findings in patients with and without malignancy

Purpose The aim was to compare computed tomography (CT) findings between patients with mesenteric panniculitis (MP) with and without known malignancy. Patients and methods We retrospectively analyzed 116 consecutive patients who were diagnosed with MP on the basis of CT findings and categorized them according to the absence (Group 1: 73 patients) or presence (Group 2: 43 patients) of malignancy. Patient age and sex, diameter, size, mass effect, location, and fat density of the MP mass, presence of a pseudocapsule and/or halo sign, and lymph node status were compared between the two groups. Results MP tends to be more common in males, and this trend shows statistical significance when combining the findings for both groups (P=0.041). Patients in Group 1 were significantly younger than those in Group 2 (54.29 vs 64.77 years, P=0.001). A well-defined fatty mass at the small bowel root was observed in all patients. The halo sign was present in most cases in both groups. A pseudocapsule was observed in 36 patients (49%) in Group 1 and 29 (67%) in Group 2 (P=0.045). The average craniocaudal diameter of the MP masses on the sagittal view was 11.14 and 12.5 cm in Groups 1 and 2, respectively (P=0.005). The MP fat density was less negative in patients with malignancy (–66 vs –76 HU, P=0.001). Lymph node status was similar in both groups. Conclusion Detailed CT features should be evaluated in patients with MP, as some of these features may indicate an associated malignancy, necessitating further investigation and close follow-up.
Post-mortem detection of six human herpesviruses (HSV-1, HSV-2, VZV, EBV, CMV, HHV-6) in trigeminal and facial nerve ganglia by PCR

Background Among over 100 types of Herpesviridae viruses, eight can infect humans: herpes simplex viruses (HSV-1, HSV-2), varicella zoster virus (VZV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesviruses 6, 7, and 8 (HHV-6, HHV-7, HHV-8). After initial infection, the viruses remain latent for the lifetime of the host. The aim of this study was to determine the distribution of six different herpesviruses: HSV-1, HSV-2, VZV, EBV, CMV, and HHV-6 in trigeminal and facial nerve ganglia among a random group of Polish population. Methods The studied group consisted of 47 individuals (40 male, seven female); mean age of 47.4 ± 16.5 years) who died of independent causes (suicide, traffic accident, and poisoning, among others). Bilateral trigeminal and facial nerve ganglia of each cadaver were collected during the autopsy. Herpesviruses were detected using multiplex polymerase chain reaction technique. Results Herpesviruses were found in trigeminal and/or facial ganglia in 30/47 (63.8%) of cadavers. HHV-6 was the most prevalent of the herpesviruses and was found in nearly half of cadavers (n = 22; 46.8%), followed by HSV-1 (n = 7; 14.9%), VZV (n = 4; 8.5%), EBV (n = 4; 8.5%), HSV-2 (n = 2; 4.3%), and CMV (n = 1; 2.1%). Facial nerve ganglia (n = 23; 48.9%) were more often infected than trigeminal ganglia (n = 13; 27.7%). Discussion The results of this study have revealed a common presence of the herpesviruses in trigeminal and facial nerve ganglia among a random group of Polish population. Furthermore, the data also demonstrate simultaneous infection of the ganglia with different herpesviruses. This study has contributed to the knowledge of prevalence and localization of herpesviruses in different structures of the nervous system.
Murine Methyl Donor Deficiency Impairs Early Growth in Association with Dysmorphic Small Intestinal Crypts and Reduced Gut Microbial Community Diversity

ABSTRACT Background Folate and choline are essential methyl donor nutrients throughout the life span; however, the adverse effects of combined deficiency on early growth, intestinal epithelial morphology, and the gut microbiome remain only partially understood. Objectives We investigated the effects of dietary folate and choline deficiency on early growth, small intestinal (SI) epithelial architecture, and the gut microbiota of mice. To explore potential mechanisms for adverse effects on gut epithelial morphology, we also evaluated gene expression and DNA methylation in mouse intestinal epithelial organoids (enteroids) maintained in methyl donor–deficient (MDD) conditions. Methods Pregnant dams were administered 1 of 4 diets: 1) control diet (CD−), 2) an isocaloric MDD− diet, or 3) CD+ and 4) MDD+ formulations containing 1% succinylsulfathiazole to inhibit folate-producing gut bacteria. We weaned pups to their dams’ diet at 3 wk of age and monitored body weight and tail length pre- and postweaning. We measured serum folate, SI crypt morphology, and microbiota composition at 7 wk of age. Results Both MDD+ and MDD− diets impaired early ponderal and linear growth, lowered serum folate concentrations, and produced patchy areas of increased crypt depth throughout the SI. Succinylsulfathiazole increased crypt depth independently of diet. MDD or succinylsulfathiazole, alone or in combination, altered the gut microbiome, with decreased Bacteroidales and Clostridiales, increased Lactobacillales and Erysipelotrichaceae taxa, and decreased α-diversity indexes. Enteroids maintained in MDD media displayed dysmorphic crypt domains, altered expression of stem cell and secretory differentiation genes, and decreased DNA methylation of the glycosylation genes Beta-1,4-N-Acetyl-Galactosaminyltransferase-1 (B4galnt1) and Phosphoethanolamine/Phosphocholine-Phosphatase (Phospho1). Conclusion MDD impairs ponderal and linear growth in mice in association with dysmorphic SI crypts and reduced gut microbial diversity. In vitro methyl donor deficiency similarly induced dysmorphic crypts in mouse enteroids in conjunction with altered gene expression and DNA methylation.
Relationship between MspI polymorphism of CYP1A1 gene and the risk of endometriosis in an Iranian population: A case-control study

Background: Endometriosis is a disease that affects women of reproductive age. This disease is characterized by the presence of endometrial-like tissues (endometrial or stromal glands) outside the uterus and shows significantly elevated prevalence in industrial regions. Additionally, an interaction between genetics and environmental factors is assumed for the disease. Enzymes belonging to the cytochrome P450 (CYP) family are participated in detoxiﬁcation process of a wide range of environmental toxins and carcinogens. Thereby, they are good link for the interaction. CYP1A1 which belong to cytochrome P450 (CYPs) superfamily, is a very important gene for the metabolism of carcinogens. Objective: The aim of this study was to analyze the frequency of the MspI polymorphism of CYP1A1 gene and its relation to endometriosis. Materials and Methods: Genomic DNA was isolated from 93 endometriosis women and 139 healthy controls. Genotyping was performed using polymerase chain reaction followed by restriction fragment length polymorphism analysis. Results: Frequencies of the TT, TC, and CC genotype of CYP1A1 gene polymorphism in patients were 73.1%, 22.6%, and 4.3%, while frequencies in controls were 74.1%, 22.3%, and 3.6%, respectively. So there was no significant differences between the genotypes in two groups (p=0.961). Conclusion: According to our study, MspI polymorphism of CYP1A1 gene appears to be not associated with the risk of endometriosis in the studied population. However, additional studies, especially with larger sample size are needed to validate these findings.
Is aquatic exercise more effective than land-based exercise for knee osteoarthritis?

Background: This study aimed to systemically review the effectiveness of aquatic exercise (AQE) compared to land-based exercise (LBE) in treating knee osteoarthritis (OA). Methods: The Medline, Embase, Web of Science, Cochrane Central Register of Controlled Clinical Trials, CINAHL, and psyclNFO databases were comprehensively searched for randomized controlled trials (RCTs) evaluating the effectiveness of AQE and LBE for knee OA from their inception date to September 24, 2018. The risk of bias was examined using the Cochrane Collaboration Tool, and Review Manager 5.3 was used for data collation and analysis. Results: Eight RCTs were included, involving a total of 579 patients. The meta-analysis showed that there was no significant difference between AQE and LBE for pain relief, physical function, and improvement in the quality of life, for both short- and long-term interventions, in patients with knee OA. However, the adherence and satisfaction level for AQE was higher than for LBE. Compared to no intervention, AQE showed a mild effect for elevating activities of daily living (standardized mean difference [SMD]: −0.55, 95% confidence interval [CI] [−0.94, −0.16], P = .005) and a high effect for improving sports and recreational activities (SMD: −1.03, 95% CI [−1.82, −0.25], P = .01). Conclusion: AQE is comparable to LBE for treating knee OA.
Prevalence of vitamin D deficiency in healthy Iranian children: A systematic review and meta-analysis

Background: Vitamin D deficiency is related to rickets in children, and it can increase the risk of osteoporosis in adulthood. The aim of our study was to estimate the prevalence of vitamin D deficiency among healthy Iranian children and adolescents. Vitamin D levels less than 20ng/ml and between 20 and 30ng/ml was considered as vitamin D deficiency and insufficiency, respectively. Methods: Relevant observational studies evaluating the prevalence of vitamin D deficiency through 1 January 1990 to 28 Dec 2016, were searched in several electronic databases including Iran-Medex, Scientific Information Database (SID), Irandoc, PubMed and NLM Gateway (for MEDLINE), Web of Science, and Scopus with no restriction on language. Only full-text articles were used for data extraction and synthesis after considering the inclusion/exclusion criteria. Results: 11 studies included; the data of four studies of Iranian newborns were withdrawn because of their high heterogeneity. The prevalence of vitamin D deficiency in Iranian boys and girls were 35% (CI 95% 34–37) and 61% (CI 95% 60–63), respectively. The prevalence of vitamin D insufficiency in Iranian children and adolescents was 31% (CI 95% 30–31). Conclusion: It seems that the prevalence of vitamin D deficiency is very high among Iranian children and adolescents. The present findings could provide practical information for healthcare decision makers.
Patient-centred care for addiction treatment: a scoping review protocol

Introduction Substance use disorders are chronic conditions that require a multidimensional treatment approach. Despite ongoing efforts to diversify such treatments, evidence continues to illuminate modest rates of treatment engagement and perceived barriers to treatment. Patient-centred care (PCC) is one approach that may strengthen the responsiveness of treatments for people with problematic substance use. The aim of this scoping review is to explore how the principles of PCC have been implemented and operationalised in healthcare settings for people with problematic substance use. Methods and analysis This scoping review follows the iterative stages of the Arksey and O’Malley framework. Both empirical (from Medline, Embase, PsycINFO, CINAHL and ISI Web of Science) and grey literature references will be considered if they focused on populations with problematic substance use and described or measured PCC or one of its principles in a health-oriented context. Two reviewers will independently screen references in two successive stages of title/abstract screening and then full-text screening for references meeting title/abstract criteria. A descriptive overview, tabular and/or graphical summaries, and a directed content analysis will be carried out on extracted data. This scoping review has been registered with Open Science Framework (https://osf.io/5swvd/). Ethics and dissemination This review will systematically examine the extent and nature of existing evidence of PCC in addiction research and clinical practice. Such evidence will contribute to the operationalisation of PCC for people with problematic substance use. A multidisciplinary team has been gathered to represent the needs of people with problematic substance use, healthcare providers and decision-makers. The team’s knowledge users will be engaged throughout this review and will participate in dissemination activities (eg, workshops, presentations, publications, reports).
