Effect of creatine supplementation on kidney stones recurrence in an athlete: a case report

INTRODUCTION Several studies examined the effects of creatine monohydrate supplementation on renal function, but no previous study has investigated its effects on kidney stones in humans. OBSERVATION A renal ultrasound in a healthy young athlete (without a known renal morphological anomaly, normal kidney function, normal phospholipid and uric acid data) revealed a kidney stone of 11 mm in the lower right calyx. Extracorporeal shock wave lithotripsy was applied in order to break the down stone. Twentyone days later, a follow-up renal ultrasound showed the absence of stones in the kidney. One week later, the athlete started creatine monohydrate supplementation for two months. Fourteen months after stopping creatine monohydrate supplementation, a third renal ultrasound confirmed the absence of stones in the kidney. CONCLUSION Two months of creatine monohydrate supplementation in an athlete with a history of kidney stones could not be associated with kidney stone recurrence in the long run

Effects of Walking Football During Ramadan Fasting on Heart Rate Variability and Physical Fitness in Healthy Middle-Aged Males

This study aimed to investigate the effect of a walking football (WF) program during Ramadan fasting (RF) on heart rate variability (HRV) indices, body composition, and physical fitness in middle-aged males. Thirty-one healthy sedentary men were randomized to WF ( n = 18) and control ( n = 13) groups. Both groups participated in RF. The WF group were involved in a training program (small-sided games) of three sessions a week during RF. The time and frequency domains of HRV, body composition, handgrip, lumbar strength, Modified Agility Test (MAT), and 6-minute walk test (6MWT) were measured before Ramadan (BR), during Ramadan (DR), and after Ramadan (AR). We reported that RF has significantly altered some parameters of HRV DR; the mean HR decreased while the mean RR, LF, and HF increased. WF had a significant effect on HRV and mean HR DR compared with BR and AR decreased while mean RR, HF and LF increased. DR, body mass decreased in both groups, while body mass index (BMI) decreased and lean mass increased only in WF group. Lower body mass and BMI levels were reported AR only in WF group. Physical capacity improved AR, compared with BR, only in the WF group with longer distance in 6MWT, shorter time(s) in MAT, and higher lumbar strength levels. We conclude that RF increases parasympathetic system activity. WF practice during RF is safe and might improve body composition, physical fitness, autonomic cardiac function, and physical fitness in middle-aged males

Avian Metapneumovirus Review: A Focus on Broilers

Avian Metapneumovirus infection first emerged in South African turkeys, followed by respiratory problems in chickens with a swollen head syndrome. The etiological agent is a Metapneumovirus in the Pneumoviridae family and the first pneumovirus identified in avian species. This virus causes respiratory and reproductive affections that are worsened in the presence of other pathogens. The present review summarized the current knowledge about the virus’s properties and spread, its different subtypes, and the immunological and pathological mechanisms, especially in the broilers. The diagnostic methods are based on serology and essentially ELISA to show and titer antibodies following infection in naïve birds. Molecular tools such as PCR aim to detect and subtype avian Metapneumovirus genetic material. Besides biosecurity, prevention relies mostly on good management and vaccination

Association of Ramadan Participation with Psychological Parameters: A Cross-Sectional Study during the COVID-19 Pandemic in Iran

COVID-19 restrictions are associated with poor physical-activity (PA). Less is known about the relationship between the combination of these restrictions with Ramadan intermittent fasting (RIF), PA, mental health, and sleep-quality. The present study aimed to evaluate whether COVID-19 restrictions and RIF during the fourth wave of the COVID-19 pandemic in Iran are associated with poor PA, anxiety, well-being, and sleep-quality outcomes. A total of 510 individuals participated in an online questionnaire that was disseminated to adults (≥18 years) residing in Iran from 13 May 2021 to 16 May 2021 (~3 days), just after the end of Ramadan 2021. PA behavior (Godin-Shephard Leisure-Time Exercise Questionnaire), anxiety (General Anxiety Disorder-7), well-being (Mental Health Continuum-Short Form), and sleep-quality (Pittsburgh Sleep Quality Index). Of 510 individuals included in the study (331 female (64.9%); mean ± SD, 31 ± 12 years), 172 (33.7%) reported less PA during the Ramadan 2021. PA was associated with better well-being and sleep-quality outcomes. Regardless of PA, participants who fasted for all of Ramadan had less anxiety and better well-being outcomes than those who fasted part of Ramadan or did not fast at all. However, the fasting part of Ramadan decreased the sleep-quality of active participants. The Ramadan 2021 was associated with poor PA, well-being, and sleep-quality of Iranians. However, PA was associated with better well-being and sleep-quality outcomes, and those who fasted all Ramadan had better anxiety and well-being outcomes. Therefore, PA during Ramadan might be an essential and scalable mental health resilience builder during COVID-19 restrictions which should be encouraged.

What should a family physician know about nutrition and physical exercise rehabilitation’ advices to communicate to ‘long-term COVID-19’ patients?

In real practice, there is a paradox in the management of patients with 'long-term Covid-19.' Indeed, Family physicians (FPs) are on the front line in the management process of these patients. For 'long-term Covid-19' patients, and according to the World Health Organization guideline, the cardiopulmonary rehabilitation (CPR) should be provided not only at tertiary- or secondary care but mainly at primary care with a real implication of FPs. However, specific guidelines/recommendations were addressed for FPs. Therefore, an alternative including the CPR minimal advice that an FP should provide to 'long-term Covid-19' patients, seems to be necessary to respond to the needs of FPs to face their involvement with 'long-term Covid-19' patients. Thus, this paper aimed to report the CPR 'minimal advice' that should be provided by FPs managing 'long-term Covid-19' patients with incapacity (i.e.; alteration of the cardiorespiratory and muscular chain). According to the authors, FPs should be more cautious in the prescription of exercise and nutrition program and informed about the minimal advices related to nutritional and physical exercise rehabilitation guidelines when taking care of 'long-term Covid-19' patients, and how these guidelines can relieve the mental and physical problems, improve immunity, and accelerate the recovery process of the patients. With the occurrence of new variants of the severe acute respiratory syndrome coronavirus 2, the nutritional and exercise rehabilitation guidelines implemented by FPs become indispensable to promote the recovery of Covid-19 patients and support a return to normal life.

A Very Virulent Genotype of Infectious Bursal Disease Virus Predominantly Associated with Recurrent Infectious Bursal Disease Outbreaks in Tunisian Vaccinated Flocks

International audienceOutbreaks of infectious bursal disease (IBD) still continue to afflict the Tunisian poultry industry even in those flocks where the vaccination program is strictly applied. To characterize the viruses that circumvent protection provided by vaccination, field isolates of infectious bursal disease virus (IBDV) obtained from vaccinated flocks that have repeatedly experienced IBDV outbreak episodes were analyzed from bursal samples by reverse transcription coupled with polymerase chain reaction and dideoxynucleotide sequencing of the VP2 hypervariable region. Although sequence data were obtained from samples collected from three distinct flocks over a period of 3 years, only limited sequence variation has been observed. The few nucleotide changes were silent and the deduced amino acid sequences were identical. Thus, the virus population that predominates in the field seems to represent a homogeneous antigenic pool. Compared with the VP2 sequences of several IBDV strains, this predominant pool was found to be closely related to the very virulent (vv) IBDV viruses described in Europe and Asia. Sequence and phylogenetic analysis of the precursor polyprotein coding sequence of a representative Tunisian isolate further confirmed its assignment to the vv genotype. The deduced amino acid sequence of the whole polyprotein of the Tunisian isolate was found to be identical to a South Korean IBDV strain. Alignment of the polyprotein amino acid sequence of 35 IBDV strains identified additional mutations outside the VP2 variable domain and which occur frequently in vv strains. Based on this comparative analysis, the set of amino acid residues that should represent a typical vv profile involves Ala222, Ile242, Ile256, Ile294, Leu451, Tyr680, N685, Ser715, Asp751, Val990, and Ala1005. Such a combination of amino acid changes was observed for the majority of vvIBDV strains that define a distinct phylogroup

Effect of purslane seed supplementation on inflammatory cytokines, oxidative stress and muscle damage in response to high?intensity intermittent exercise in national athlete runners.

Background Purslane supplementation has anti-oxidative, anti-inflammatory, skeletal muscle-relaxant activities. However, it is unknown if the ingestion of purslane will affect the oxidative stress and cytokines in exercise-induced muscle damage. The aim of the present study was to examine the effect of purslane supplementation after high-intensity interval exercise (HIIE) on oxidative stress, cytokines, and muscle damage level in young athlete male runners. Methods Seven healthy young male runners performed 2.5 km HIIE treadmill protocol. Athletes repeated this protocol following 10 days of purslane seed supplementation (1000 mg/day). Blood samples were collected at baseline and following HIIE protocol and analyzed for oxidative stress (9-HODE and 13-HODE), cytokines (IL-17, and TNF-?), and muscle damage (LDH) biomarkers. Results At baseline and following HIIE protocol, 9-HODE, 13-HODE, IL-17, TNF-?, LDH levels were significantly (p < 0.001) lower after purslane supplementation in compared to before purslane supplementation. HIIE protocol induced a significant increase in 9-HODE, 13-HODE, IL-17, TNF-?, and LDH before and after purslane supplementation. Conclusion Purslane seed supplementation was able to reduce oxidative stress (9-HODE, 13-HODE), proinflammatory cytokines (IL-17 and TNF-?), and muscle damage (LDH) in male runners after HIIE performance compared to baseline levels. After 10 days of supplementation, the levels were reduced compared to levels pre-supplementation but not after HIIE supplementation in supplemented athletes
