Koumiss and immunity: A thorough investigation of fermentation parameters and their impact on health benefits.

The aim of this study was to determine the components and cytokine and immunoglobulin levels of koumiss during different fermentation periods, and to reveal the interrelation between these parameters. For achieving this objective, 10 samples of koumiss were prepared and randomly divided into 2 groups: the first group was sampled at 0, 1, 5, 12, and 24 h of incubation at room temperature for analysis. The second group was stored at +4°C, and samples were taken on d 5, 10, 15, and 20. The counts of Enterobacteriaceae spp., Staphylococcus, and Micrococcus spp. progressively decreased with the period of fermentation until becoming undetectable in the final samples of both groups. We fond positive or negative correlations between cytokine and immunoglobulin levels and the physicochemical and microbiological parameters in the koumiss samples in both groups. However, the levels of IFN-γ, IL-2, TNF-α, and IgG did not change significantly over time in both groups. Overall, it is clear that traditionally prepared koumiss under different fermentation times and temperatures does not show any differences in cytokine and immunoglobulin concentrations.

The Impact of Postural and Anthropometric Properties of Foot and Ankle on Physical Performance and Ambulation of Patients with Duchenne Muscular Dystrophy.

BACKGROUND: Abnormal foot anthropometry and posture of patients with Duchenne Muscular Dystrophy (DMD) can be considered as possible risk factors for performance and ambulation. It was aimed to examine the effects of foot posture and anthropometric characteristics, which deteriorated from the early period, on ambulation and performance of patients with DMD. METHODS: The foot arch height (FAH), the metatarsal width (MW), subtalar pronation angle, and ankle limitation degree (ALD) were evaluated to determine the foot anthropometric characteristics of the patients. Foot Posture Index-6 (FPI-6) was used to evaluate foot posture. The performance of the patients was determined by the 6-minute walk test (6MWT), the 10-meter walk test (10MWT), and ascend/descend a standard 4-step test, and the ambulation was determined by the North Star Ambulatory Assessment (NSAA). Spearman's correlation coefficient was calculated to assess the relationship between foot anthropometric characteristics and posture, and performance and ambulation. RESULTS: The sample consisted of 48 patients with DMD aged 5.5 to 12 years. Both of the right and left foot FPI-6 scores were associated with all parameters, except descending 4-step. The left FAH was associated with 6MWT and NSAA, and the left MW was associated with 6MWT. The ALD of right foot was associated with 6MWT, ascending/descending 4 steps, and NSAA, and left ankle limitation was associated with NSAA (p<0.05). There was no relationship between other parameters. CONCLUSIONS: These findings suggest that postural disorders in the foot and ankle may contribute to the decrease in performance and ambulation in patients with DMD.

Motor imagery ability of children with duchenne muscular dystrophy: Reliability and validity of kinesthetic and Visual Imagery Questionnaire-10, and its association with cognitive status.

PURPOSE: To investigate validity and reliability of the Kinesthetic and Visual Imagery Questionnaire-10 (KVIQ-10) in children with Duchenne Muscular Dystrophy (DMD), to compare the motor imagery (MI) ability with age-matched controls, and to examine the relationship between MI ability and cognitive status. METHODS: The research involved 38 children who were diagnosed with DMD, as well as 20 healthy controls aged between 7 and 18 years. The KVIQ-10 was assessed for its test-retest reliability, internal consistency, construct and concurrent validity. The Motor Imagery Questionnaire for Children (MIQ-C) was selected as the gold standard test for concurrent validity. Cognitive function was assessed using the Modified Mini Mental Test (MMMT) and Montreal Cognitive Assessment (MoCA). RESULTS: KVIQ-10 showed excellent test-retest reliability (ICC>0.90) and high internal consistency (Cronbach's alpha>0.70). A moderate-to-strong association was found between KVIQ-10 and MIQ-C subscales (p < 0.001). KVIQ-10 and MIQ-C subscores were statistically lower in the DMD group (p ≤ 0.05). A correlation was found between MoCA and KVIQ-10 in children with DMD (p ≤ 0.05). CONCLUSIONS: The KVIQ-10 is a reliable and valid measure to assess the MI ability of children with DMD whose imagery ability was determined to be impaired.

Effects of cycling training on balance and gait in children with Duchenne muscular dystrophy: A randomized controlled study.

BACKGROUND AND AIMS: Although aerobic exercises such as cycling and swimming are increasingly being recommended in Duchenne muscular dystrophy (DMD), their effect on gait and balance parameters is unclear. This study was aimed to investigate the effect of cycling training on balance and spatio-temporal gait parameters in children with DMD. METHODS: Ambulant children (age range: 6.17-11.33 years) were randomly divided into two groups: home-based exercise training applied in the control group (n = 12) while 12 weeks of supervised submaximal lower extremity cycling training in addition to home-based exercise training performed in the study group (n = 11). Gait and balance parameters were evaluated using the GAITRite electronic walkway system and the Bertec Balance Check Screener™, respectively. Assessments were applied before and after 12 weeks of training. RESULTS: The mean ages of the children in the study and control groups were 8.20 (SD:1.34) and 8.86 (SD:1.30) years, consecutively (p > 0.05). Considering the baseline values, the balance and spatio-temporal gait parameters of the children were similar except for the antero-posterior postural sway on the perturbed surface with eyes open (p > 0.05). There was a significant time x group interaction effect in favor of the study group for the antero-posterior postural sway of children on the normal surface with eyes open (F (1,58) = 12.62, p = 0.002). It was found that the antero-posterior postural sway on the normal surface with eyes open was improved in the study group within group comparison (F (1,10) = 8.50, p = 0.015). CONCLUSIONS: The study showed that both the cycling and the home-based exercise training groups may maintain gait and balance parameters during the study. Adding a cycling training to the rehabilitation program can also provide additional contribution to improve antero-posterior balance.

The effect of deep brain stimulation on lower extremity dexterity in people with Parkinson's disease.

PURPOSE: To examine the effect of deep brain stimulation (DBS) on lower extremity dexterity in people with Parkinson's disease (PwPD) and to investigate the relationship between this effect and the effect of DBS on measures of different walking characteristics, and other features of Parkinson's disease. MATERIALS AND METHODS: Thirty-six PwPD were included. Assessment was performed twice with DBS "on" and DBS "off" state. RESULTS: The LEDT scores of both extremities, the Unified Parkinson Disease Rating Scale-motor section (UPDRS-III), the 10-Meter Walk Test (TMWT), the Timed Up and Go Test (TUG), the Figure-of-Eight Walk Test (FEWT), and the Three-Meter Backward Walk Test (TMBWT) scores were significantly better in "on" DBS condition than "off" DBS condition. The effect of DBS on lower extremity dexterity is related to age and levodopa equivalent daily dosage (LEDD). The effect of DBS on lower extremity dexterity and the effect of DBS on the bradykinesia, TUG, the FEWT, and the TMBWT were also related. CONCLUSIONS: DBS has a positive effect on lower extremity dexterity. Clinical characteristics such as age and LEDD and the effect of DBS on bradykinesia, walking with turning, curved walking, and backward walking is related with the effect of DBS on lower extremity dexterity.

The age and levodopa equivalent daily dosage values of the patients should be considered when examining lower extremity dexterity in people with Parkinson's disease who have undergone deep brain stimulation (DBS).It may be beneficial to apply exercises to improve lower extremity dexterity for patients whose symptoms of bradykinesia do not progress as expected after DBS.Applying exercises to improve lower extremity dexterity may also be beneficial for patients who have complex walking deficits after DBS.

Metrisor: A novel diagnostic method for metritis detection in cattle based on machine learning and sensors.

The Metrisor device has been developed using gas sensors for rapid, highly accurate and effective diagnosis of metritis. 513 cattle uteri were collected from abattoirs and swabs were taken for microbiological testing. The Metrisor device was used to measure intrauterine gases. The results showed a bacterial growth rate of 75.75 % in uteri with clinical metritis. In uteri positive for clinical metritis, the most commonly isolated and identified bacteria were Trueperella pyogenes, Fusobacterium necrophorum and Escherichia coli. Measurements taken with Metrisor to determine the presence of metritis in the uterus yielded the most successful results in evaluations of relevant machine learning algorithms. The ICO (Iterative Classifier Optimizer) algorithm achieved 71.22 % accuracy, 64.40 % precision and 71.20 % recall. Experiments were conducted to examine bacterial growth in the uterus and the random forest algorithm produced the most successful results with accuracy, precision and recall values of 78.16 %, 75.30 % and 78.20 % respectively. ICO also showed high performance in experiments to determine bacterial growth in metritis-positive uteri, with accuracy, precision and recall values of 78.97 %, 77.20 % and 79.00 %, respectively. In conclusion, the Metrisor device demonstrated high accuracy in detecting metritis and bacterial growth in uteri and could identify bacteria such as E. coli, S. aureus, coagulase-negative staphylococci, T. pyogenes, Bacillus spp., Clostridium spp. and F. necrophorum with rates up to 80 %. It provides a reliable, rapid and effective means of detecting metritis in animals in the field without the need for laboratory facilities.

Sleep quality and daytime sleepiness amongst family caregivers of children with Spinal Muscular Atrophy.

BACKGROUND: While there are limited studies focusing on sleep quality of family caregivers of children with Spinal Muscular Atrophy (SMA), there are no studies on daytime sleepiness in SMA. AIMS: This study aimed a) to compare the sleep quality and daytime sleepiness between caregivers of children with SMA and those of healthy peers and b) to investigate the sleep quality and daytime sleepiness of family caregivers of children with different types of SMA. METHODS AND PROCEDURES: This study included 30 family caregivers of children with SMA (SMA Type 1:12, SMA Type 2:10, and SMA Type 3:8) and 31 family caregivers of healthy peers. Sleep quality and daytime sleepiness of family caregivers were evaluated using the Pittsburg Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (EPS), consecutively. OUTCOMES AND RESULTS: Demographic characteristics of children with SMA and healthy peers were similar (p > 0.05). The mean ages of family caregivers of children with SMA and healthy peers were 36.07 ± 5.84 and 35.26 ± 5.02 years, respectively (p = 0.6). The PSQI scores of family caregivers of children with SMA (7.50 ± 3.90 points) were lower than those of healthy peers (4.09 ± 1.97 points) (p < 0.001). There was no difference in PSQI scores between SMA types (p = 0.8). Also, no difference was found between SMA types and between SMA and healthy peers in terms of EPS (p > 0.05). CONCLUSIONS AND IMPLICATIONS: Family caregivers of children with SMA had poor sleep quality but similar daytime sleepiness compared with those of healthy peers. Among SMA types, family caregivers had similar sleep quality and daytime sleepiness. It was demonstrated that the sleep quality of family caregivers should be taken into consideration in the disease management of SMA.

Bi-allelic variants in CELSR3 are implicated in central nervous system and urinary tract anomalies.

CELSR3 codes for a planar cell polarity protein. We describe twelve affected individuals from eleven independent families with bi-allelic variants in CELSR3. Affected individuals presented with an overlapping phenotypic spectrum comprising central nervous system (CNS) anomalies (7/12), combined CNS anomalies and congenital anomalies of the kidneys and urinary tract (CAKUT) (3/12) and CAKUT only (2/12). Computational simulation of the 3D protein structure suggests the position of the identified variants to be implicated in penetrance and phenotype expression. CELSR3 immunolocalization in human embryonic urinary tract and transient suppression and rescue experiments of Celsr3 in fluorescent zebrafish reporter lines further support an embryonic role of CELSR3 in CNS and urinary tract formation.

Ultrasonographic assessment of lower limb muscle architecture in children with early-stage Duchenne muscular dystrophy / Avaliação ultrassonográfica da arquitetura muscular dos membros inferiores em crianças com distrofia muscular de Duchenne em estágio inicial

ABSTRACT Background: Muscle imaging methods such as ultrasound and magnetic resonance imaging have been used for many years to determine the dystrophic process in muscular dystrophies. However, the knowledge regarding muscle architecture in children at early-stage Duchenne muscular dystrophy (DMD) with different functional levels is limited. Objective: To explore the effect of functional level on muscle architectural properties in children with early stage DMD and the difference between DMD and typically developing (TD) peers. Methods: Thirty children with DMD (15 Grade 1 and 15 Grade 2 according to the Vignos Scale) and 5 TD peers were included. Ultrasound imaging was used to measure muscle thickness (MT), fascicle length (FL), and pennation angle (PA) of vastus lateralis (VL) and medial gastrocnemius (MG) muscles bilaterally. Results: The MT and FL values for VL, and MT, FL and PA values for MG muscles were higher in children with DMD compared with those of TD peers (p<0.05). The FL of VL, and MT and FL of GM muscles of children with DMD Grade 2 were higher than those of children with DMD Grade 1 (p<0.05). Conclusions: MT and FL are increased in children with DMD compared with TD peers. Additionally, muscle architecture seems to be affected even at the early stages of the disease.

RESUMO Antecedentes: Métodos de imagem muscular, como ultrassom e ressonância magnética, têm sido usados há muitos anos para determinar o processo distrófico em distrofias musculares. No entanto, o conhecimento a respeito da arquitetura muscular em crianças com distrofia muscular de Duchenne (DMD) em estágio inicial, com diferentes níveis funcionais, é limitado. Objetivo: Explorar o efeito do nível funcional nas propriedades arquitetônicas do músculo em crianças com DMD em estágio inicial e a diferença entre DMD e seus pares em desenvolvimento típico (DT). Métodos: Trinta crianças com DMD (15 Grau 1 e 15 Grau 2 de acordo com a Escala de Vignos) e cinco colegas DT foram incluídos. A ultrassonografia foi usada para medir a espessura muscular (EM), o comprimento do fascículo (FL) e o ângulo de penetração (PA) dos músculos vasto lateral (VL) e gastrocnêmio medial (MG) bilateralmente. Resultados: Os valores de EM e FL para VL e os valores de EM, FL e PA para músculos MG foram maiores em crianças com DMD em comparação com os de seus pares DT (p<0,05). O FL do VL e o EM e o FL dos músculos GM de crianças com DMD Grau 2 foram maiores do que aqueles de crianças com DMD Grau 1 (p<0,05). Conclusões: TM e FL estão aumentados em crianças com DMD em comparação com seus pares DT. Além disso, a arquitetura muscular parece ser afetada mesmo nos estágios iniciais da doença.

The association of hand grip strength with functional measures in non-ambulatory children with Duchenne muscular dystrophy / Associação da força de preensão manual com medidas funcionais em crianças com distrofia muscular de Duchenne, que não deambulam

ABSTRACT Duchenne muscular dystrophy (DMD) is a disease characterized by progressive loss of muscle fiber, gradually from proximal to distal. Although a few studies have investigated hand grip strength in non-ambulatory DMD patients, a lack of literature was found determining its relationship with functional capacity. Objective: The aim of this study was to determine the associations between hand grip strength and functional measures in non-ambulatory children with DMD. Methods: Hand grip strength was evaluated using a dynamometer in children with DMD. The children with DMD were evaluated with the Turkish version of the Egen Klassifikation Scale Version 2 (EK2) for global functional capacity, the Performance of Upper Limb (PUL) for upper limb functional performance and the ABILHAND-Kids for hand ability. Results: The mean age of 38 DMD children was 12.02 ± 1.99 years. Dominant hand grip strength of the children with DMD was higher than the non-dominant hand (p < 0.05). The EK2 was 13.02 ± 5.50, PUL was 49.86 ± 14.34 and ABILHAND-Kids was 26.81 ± 7.59. Hand grip strength was found to be correlated with the EK2 (p < 0.05). Conclusions: It is known that measuring functional ability and strength in very weak children with DMD has been difficult and complex for therapists/clinicians in the clinical environment. Although there is a moderate correlation, hand grip strength may be used in clinical practice as a practical assessment tool to have an immediate insight into the global functional capacity in non-ambulatory DMD children.

RESUMO A distrofia muscular de Duchenne (DMD) é uma doença caracterizada por perda progressiva da fibra muscular, gradualmente de proximal a distal. Embora poucos estudos tenham investigado a força de preensão manual em pacientes com DMD não ambulatoriais, foi observada uma falta de literatura para determinar suas relações com a capacidade funcional. Objetivo: O objetivo deste estudo foi determinar as associações entre força de preensão manual e medidas funcionais em crianças não ambulatoriais com DMD. Métodos: A força de preensão manual foi avaliada com dinamômetro em crianças com DMD. As crianças com DMD foram avaliadas com a versão turca da Egen Klassifikation Scale Versão 2 (EK2) para capacidade funcional global, desempenho do membro superior (PUL) para desempenho funcional do membro superior e ABILHAND-Kids para a habilidade manual. Resultados: A idade média de trinta e oito crianças com DMD foi de 12,02 ± 1,99. A força de preensão manual dominante das crianças com DMD foi maior que a da mão não dominante (p < 0,05). A EK2 foi calculada em 13,02 ± 5,50, PUL em 49,86 ± 14,34 e ABILHAND-Kids em 26,81 ± 7,59. A força de preensão manual foi correlacionada com a EK2 (p < 0,05). Conclusões: Sabe-se que medir a capacidade funcional e força em crianças muito fracas com DMD tem sido difícil e complexo para terapeutas / clínicos em ambiente clínico. Embora exista uma correlação moderada, a força de preensão manual pode ser usada na prática clínica como uma ferramenta de avaliação prática para obter imediatamente uma percepção da capacidade funcional global em crianças com DMD não ambulatoriais.
