Methylmalonic acid levels may be used for monitoring response to treatment, thereby identifying patients of the subgroup in which disease outcome may improve.
Psychiatric symptoms are common in multiple sclerosis. The relationship of emotional state with respiratory function is unclear in these patients. We aimed to evaluate the relationship between the clinical characteristics, anxiety and depression status, and respiratory functions of patients with relapsing-remitting multiple sclerosis (RRMS).

The research was planned as a prospective case-control study. Ninety RRMS patients and 50 healthy controls were included in the study. The MS diagnosis was confirmed according to the revised 2017 McDonald's criteria. Disability was divided into two subgroups according to the Expanded Disability Status Scale (EDSS) (under 3.5 and 3.5-5.5). Beck anxiety and Beck depression inventories evaluated. A pulmonary function test was performed with a computerized spirometry device. Forced expiratory volume-1st second (FEV1), forced vital capacity (FVC), FEV/FVC, peak expiratory flow (PEF), maximal expiratory flow (MEF), peak inspiratory flow (PIF), and maximal inspiratory flow (MIF) values were obtained.

There were 90 RRMS patients with a mean age of 38.68±10.95 years, and 58 (64.40%) were female in the study. The anxiety and depression scores of the patients were significantly higher than the control group (p=0.02, 0.002). FVC and FEV1 values were lower in patients with higher Beck depression scores (p=0.012, 0.007). FVC, FEV1, MEF50, and PIF values were lower in patients with higher Beck anxiety scores (p=0.002, 0.002, 0.030, 0.027). TGFbeta inhibitor When EDSS and number of attacks were fixed, there was a low to moderate correlation between anxiety and FEV1-FVC (p=0.001, r=-367, -0.360 respectively), and a low negative correlation between depression and FEV1 (p=0.045, r=-0.214).

Anxiety and depression scores are higher in patients with RRMS. Depression and anxiety are particularly associated with low FVC and FEV1 in patients.

The outbreak of coronavirus disease 2019 (COVID-19) has rapidly spread and developed as a pandemic threatening global health. Patients with multiple sclerosis (MS)-an autoimmune demyelinating inflammatory disease of the central nervous system (CNS)-are predominantly treated with immunomodulatory/immunosuppressive disease-modifying therapies (DMTs), which can increase the risk of infection. Therefore, there is concern that these patients may have a higher risk of COVID-19. In response to growing concerns of neurologists and patients, this study aimed to determine the prevalence, severity, and possible complications of COVID-19 infection in patients with MS in Saudi Arabia (SA).

In this prospective cohort study, demographic and clinical data were obtained from patients residing in SA with MS who had a positive result for COVID-19 per reverse transcription-polymerase chain reaction test or viral gene sequencing, using respiratory or plasma samples. Comparison of COVID-19 severity groups was performed using oisease duration, and DMT use at the time of infection showed no significant differences. A higher percentage of patients who were admitted to hospital or the ICU (40%; p=0.026) presented with an MS relapse within the prior four weeks compared with those who were asymptomatic or had a mild infection (both 8.3%).

These findings present a reassuring picture regarding COVID-19 infection in patients with MS. However, patients with MS who have had a relapse in the preceding four weeks (requiring glucocorticoid treatment) may have an increased risk of severe COVID-19.

Some people with multiple sclerosis (pwMS) are at increased risk of severe Coronavirus disease 19 (COVID-19) and should be rapidly vaccinated. However, vaccine supplies are limited, and there are concerns about side-effects, particularly with the ChAdOx1nCoV-19 (AstraZeneca) vaccine.

To report our first experience of pwMS receiving the AstraZeneca vaccine.

Service evaluation. pwMS using the MS service at Barts Health NHS Trust were sent questionnaires to report symptoms following vaccination.

Thirty-three responses were returned, 29/33 pwMS received a first dose of AstraZeneca vaccine, the remaining four received a first dose of BioNTech/Pfizer vaccine. All but two patients (94%) reported any symptoms including a sore arm (70%), flu-like symptoms (64%), fever (21%), fatigue (27%), and headache (21%). In more than 2/3 patients, symptoms lasted up to 48 hours, and with the exception of two pwMS reporting symptom duration of 10 and 12 days, respectively, symptoms in the remainder resolved within seven days. No severe adverse effects occurred.

pwMS report transient symptoms following AstraZeneca vaccination, characteristics of which were similar to those reported in the non-MS population. Symptoms may be more pronounced in pwMS due to the temperature-dependent delay in impulse propagation (Uhthoff's phenomenon) due to demyelination.

Despite the recent advances, the pathomechanism underlying the WS remains elusive. The aim of this study was to characterize morphological and molecular features of WS in broiler chickens. 50 pectoralis muscles were collected from 55 days old ROSS 308 broiler chickens with a mean weight of 3.5 kg. Samples were snap frozen and analyzed by histopathology, immunohistochemistry, and immunofluorescence. Real-time-PCR was used to evaluate the expression of different cytokines. Histological lesions were observed in all examined animals, both with and without macroscopic evidence of WS. WS muscles showed endomysial and perivascular inflammatory infiltrates of macrophages and cluster of differentiation (CD)8-positive T lymphocytes with severe myofiber atrophy, necrosis, fibrosis and replacement by adipose tissue. There was diffuse sarcoplasmic and sarcolemmal overexpression of the major histocompatibility complex class I (MHC I). The severity of the histologic lesions was positively correlated with the macroscopic degree of white striations. IL-6, IL-17 and lipopolysaccharide-induced TNF-α factor (LITAF) were overexpressed in severe lesions of WS. The presence of the CD8/MHC I complexes, together with the higher expression of IL-6, IL-17 and LITAF in severe degree of WS, suggest that the immune response may be involved in the progression of this myopathy and can be consistent with a hypoxia-induced inflammatory myopathy. These results help to understand the pathomechanism of WS contributing to the reduction of economic losses and improving poultry welfare.The study evaluated the effect of housing system, insemination frequency, and sperm concentration on hatching traits of commercial broiler breeder. Experiment was set up as 2 × 4 × 4 factorial arrangement under completely randomized design. A total of 960 broiler breeder females (Ross-308) were divided evenly (480) into two groups for Artificial Insemination in cages (AIC) and on deep litter floor (AIF) with 41 and 48 males were allocated for aforesaid flocks, respectively. Females birds of both flocks (AIC and AIF) were further divided into 4 treatment groups to apply 4 various insemination frequencies at 4, 6, 8, and 10th days. These treated groups were further divided into 4 subgroups to apply each of insemination frequencies with 4 different sperm concentrations per insemination dose 100, 125, 150, and 175 × 106 sperms during peak phase of production which were replaced with 200, 225, 250, and 275 × 106 sperms in post peak phase. According to the results, significantly higher egg production, fertility, hatchability and number of chicks were documented when AI was conducted in cages as compared to deep litter floor. Although, the best reproductive performance was observed on 4 and 6th day insemination frequencies on all subjected sperm concentrations during peak; however, these parameters were found better on only 4th day during post peak. Sperms concentrations of 150, 175 × 106 during peak and 250 and 275 × 106 during post peak brought forth the best reproductive performance on all insemination frequencies. Although, embryonic mortality was significantly higher, when AI was conducted in floored flocks particularly when repeated after 4th day; however, various sperm concentrations found inert. In conclusion, AI found advantageous in caged flock as compared to floored. The consortium of different insemination frequencies and sperms concentrations are required for sustainable reproductive traits with progression of breeder age.In recent years, neohesperidin dihydrochalcone (NHDC), as a class of natural flavonoids, has received more and more attention in nutrition research. However, the research on the application of NHDC in the laying hens is rarely reported. This study was conducted to determine the effects that different concentrations of dietary NHDC have on the production performance, egg quality, serum biochemistry and intestinal morphology of laying hens. A total of 240 Lohmann commercial laying hens (66 wk old) were divided into 4 groups, with each group's diet containing a different concentration of NHDC (0, 100 mg/kg, 200 mg/kg, and 400 mg/kg). Significant associations were found between NHDC consumption and both higher egg production (P = 0.050) and lower FCR (P = 0.028) after 12 wk NHDC feed. At 12 wk, eggs produced by hens consuming a 200 mg/kg NHDC diet had significantly thicker eggshells (P = 0.059) than those produced by hens consuming a 400 mg/kg diet. Dietary NHDC addition improved albumen height and Haugh unit after 15 d of storage (P less then 0.01). However, no significant associations between NHDC consumption and these factors were identified after 12 wk. Dietary NHDC addition had no significant effects apparent of gel properties at 12 wk. In addition, NHDC can effectively reduce the content of total cholesterol (TC) (P = 0.042) and Groups treated with 100 mg/kg NHDC supplementation showed significantly increased T-AOC concentrations compared to control (P = 0.013) in serum. Hens fed an NHDC-supplemented diet exhibited a longer villus height and a higher villus/crypt ratio in the ileum (P less then 0.01) as compared to controls, as well as lower crypt depth in the duodenum, jejunum and ileum. These results indicate that, as compared to a control diet, an NHDC-supplemented diet results in higher egg production and quality, as well as improvement in egg gel properties, serum biochemistry and intestinal morphology.
