Effects of Fitlight training on cognitive-motor performance in élite judo athletes

AimsThe aims of this study were to verify if a 5-week cognitive-motor training (CMT) using FitlightsTM induced changes in young adult judo athletes compared to a non-intervention group. Specifically, it was verified if CMT influenced executive functions (EFs), physical fitness and brain-derived neurotrophic factor (BDNF) levels. Additionally, athletes’ competitive results were compared between groups. MethodTwenty-seven athletes (14 males and 13 females; age = 19.5 ± 2.0 years) were assigned to the Fitlight (FG) and control (CG) groups which performed 5 weeks of CMT, respectively, including 25 min per day of Fitlight training or traditional judo practice. All participants performed cognitive (flanker task and forward/backward digit span) and fitness tests (counter movement jump, handgrip test, dynamic and isometric chin up). In addition, BDNF was collected by saliva sampling and competitive results after the intervention period were considered. ResultsRM-ANOVA showed significant differences in FG for the accuracy of flanker (p = 0.028) and backward digit span (p < 0.001). Moreover, significant differences in FG were found for relative dynamic chin up (p = 0.027) and counter movement jump (p = 0.05). In addition, a significant difference in FG was found for competitive results after the intervention period (p < 0.01).No significant differences were found for BDNF and other cognitive and fitness measures (p > 0.05). ConclusionA 5-week judo-specific CMT improved EFs and motor performance in élite judo athletes. It seems that CMT with Fitlight™ could be considered an additional support to coaches during the training period.

Systemic Oxidative Stress in Subacute Stroke Patients Undergoing Rehabilitation Treatment.

The imbalance in oxidative stress in acute stroke has been extensively studied; on the contrary, its investigation in the subacute phase is limited. The aim of this study was to analyse the variation in the systemic oxidative status in subacute post-stroke patients before (T0) and after a six-week rehabilitation treatment (T1) and to investigate the relationship between systemic oxidative status and rehabilitation outcomes. We enrolled 109 subjects in two different centres, and we analysed their serum hydroperoxide levels (d-ROMs), biological antioxidant power (BAP), thiol antioxidant components (-SHp), and relative antioxidant capacity (OSI and SH-OSI indices). Activity of Daily Living (ADL), hand grip strength, and walking endurance were evaluated using the modified Barthel Index, the Hand Grip test, and the 6-min walk test, respectively. At T0, most of the patients showed very high levels of d-ROMs and suboptimal levels of the BAP, OSI, and SH-OSI indices. Comparing the T1 and T0 data, we observed an improvement in the rehabilitation outcomes and a significant decrease in d-ROMs (549 ± 126 vs. 523 ± 148, p = 0.023), as well as an improvement in the OSI and SH-OSI indices (4.3 ± 1.3 vs. 4.7 ± 1.5, p = 0.001; 11.0 ± 0.4 vs. 1.2 ± 0.4, p < 0.001). In addition, significant correlations were seen between the oxidative stress parameters and the rehabilitation outcomes. These results suggest monitoring the systemic oxidative stress status in post-stroke patients in order to plan a tailored intervention, considering its relationship with functional recovery.

24-H movement behaviors and physical fitness in preschoolers: A compositional and isotemporal reallocation analysis

Background/ObjectivesThis study examined the relationships between 24-h movement behaviors and physical fitness (PF) in preschool children. MethodsThe study was conducted on 474 children aged 3–6 years in Zhuhai. Physical activity (PA) and sedentary behavior (SB) were collected by the accelerometer, and sleep time was assessed through the parent-report questionnaire. Balance, cardiorespiratory fitness (CRF), flexibility, muscle strength, muscular endurance, and speed-agility were measured using a balance beam test, 20 m shuttle run test, sit and reach test, handgrip test, sit-ups, and 4 × 10 m shuttle run test respectively. The compositional data analysis was used to examine the association between 24-h movement behaviors and PF, and the compositional isotemporal substitution analysis was used for the time reallocation. ResultsThe daily composition, adjusted for age, gender, and body mass index (BMI), was significantly associated with CRF (p < 0.001, r2 = 0.20), flexibility (p < 0.001, r2 = 0.07), muscular strength (p < 0.001, r2 = 0.37), muscular endurance (p < 0.001, r2 = 0.26), and speed-agility (p < 0.001, r2 = 0.26). The addition of moderate-to-vigorous PA (MVPA) at the expense of SB and sleep, MVPA at the cost of sleep, was associated with significant muscular strength and speed-agility improvements respectively. The impact of SB and sleep replacing MVPA is stronger than MVPA replacing SB and sleep on muscular strength. ConclusionThese findings offer useful insight for the replacement of movement behaviors within the recommended range to facilitate PF development in early childhood.

Keep calm and keep rowing: the psychophysical effects of dragon boat program in breast cancer survivors

PurposeDragon Boat discipline has become a popular type of physical exercise among women with breast cancer. The present study aims to investigate the effects of Dragon Boat activity on body composition, physical function, and psychosocial aspects (i.e., body appreciation and quality of life [QoL]) in women operated for breast cancer.MethodsThirty-one women (age, 57.88 ± 7.88 years; BMI, 27.86 ± 6.38 kg·m−2) with a previous breast removal surgery were recruited and randomized into two groups: Dragon Boat group (DB, N = 18) or a home-based non-supervised training program (home exercise group; HG, N = 13). All participants underwent body composition, handgrip test, 30-s chair stand test (30CST), 6-min walking test (6MWT), and shoulder mobility measurements at baseline and after 12 weeks of intervention. Participants also filled out the Body Appreciation Scale-2 (BAS-2) and the Short Form Health Survey-12 (SF-12) self-report questionnaires.ResultsDragon Boat activity significantly improved the 30CST (+ 6%, p = .011) and 6MWT performance (+ 30%, p = .011) compared to a home-based non-supervised training program. Moreover, 20% (3/15 women) of women in the DB group obtained a reliable change from pre- to post-intervention in the BAS-2 and in the mental QoL component of the SF-12 (vs 15% and 0% of the HC group). No reliable change emerged for the physical component of the SF-12.ConclusionDragon Boat activity is efficient to improve lower limb strength in women operated for breast cancer. Furthermore, Dragon Boat activity emerged to improve body appreciation and mental QoL in some of the women assigned to this activity. Importantly, no adverse events were documented during the intervention.Trial registrationNCT05206526 (10/02/2022)

Systemic and ocular pressure changes following sympathetic activation in yoga practitioners - A comparative study

Introduction and Aim: Blood Pressure (BP), Intraocular Pressure (IOP) and Ocular Perfusion Pressure (OPP) are precursor parameters that lead to development of glaucoma. Under conditions of stress, either physical or psychological origin, there is disturbance of autonomic regulation. This causes increased activation of the sympathetic nervous system which might influence BP and ocular pressures. An altered autonomic balance towards lower sympathetic drive is observed in subjects practicing yoga, but it is not clear whether this adaptation also influences ocular pressures. Our study attempted to analyze variations in BP, IOP and OPP following sympathetic activation in yogic practitioners and non-practitioners of yoga. Materials and Methods: One hundred and ten subjects aged 18 - 25 years were recruited and categorised into yoga and non-yoga group. Basal BP was recorded using a sphygmomanometer and IOP was recorded using a rebound tonometer. Isometric hand grip (IHG) and Cold pressor test (CPT) were administered one at a time. IOP and BP were recorded immediately following these sympathetic activation tests. Mean arterial pressure and OPP was calculated using standard formula. Results: Significant increase in the values of pulse, BP, IOP and OPP following sympathetic activation were observed in the non-yoga group which was not noted in the yoga group. Elevation in systemic and ocular pressures following sympathetic activation was less in yoga practitioners. This adrenergic response was greater in the non-yoga group. Conclusion: Regular yoga practice maintains adequate perfusion of ocular tissues by autoregulation. Hence yoga can be recommended as a complementary health approach for the autonomic nervous system imbalance.

Distal Versus Proximal Radial Artery Access for Cardiac Catheterization: 1-Year Outcomes

Proximal radial artery (PRA) access for cardiac catheterization is safe but can jeopardize subsequent use of the artery because of occlusion. Distal radial artery (DRA) access in the anatomical snuffbox preserves the RA but safety and potential detrimental effects on hand function are unknown. We aimed to assess hand function and complications after DRA and PRA. In this single-center trial, 300 patients were randomly allocated 1:1 to cardiac catheterization through DRA or PRA. The primary end point of change in hand function from baseline to 1 year was a composite of the Quick Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, hand grip test, and thumb-forefinger pinch test. The secondary end points included access feasibility and complications. Of 216 patients with 1-year completed follow-up, 112 were randomly allocated to DRA and 104 to PRA, with balanced demographics and procedural characteristics. Both groups had similar access site bleeding rates (DRA 0% vs PRA 1.4%, p = 0.25). Radial artery occlusion occurred in 1 PRA patient versus 2 in DRA. There was no significant difference in change of hand function, median (interquartile range) hand grip (DRA 0.7 [-3 to 4.5] vs PRA 1.3 [-2 to 4.3] kg, p = 0.57), pinch grip (DRA -0.1 [-1.1 to 1] vs PRA -0.3 [-1 to 0.7] kg, p = 0.66), and Quick DASH (DRA 0 [-6.6 to 2.3] vs PRA 0 [-4.6 to 2.9] points, p = 0.58). The composite of hand function was comparable between PRA and DRA. In conclusion, DRA is a safe strategy for cardiac catheterization, with a low complication rate. Compared with PRA, there is no increased risk of hand dysfunction or radial artery occlusion at 1 year.

Assessment of phase angle as a novel indicator for sarcopenic obesity according to the ESPEN/EASO criteria in older adults with diabetes mellitus

Sarcopenic obesity (SO) is a clinical condition in which sarcopenia and obesity occur together, and is associated with more poor clinical outcomes, increased mortality, and morbidity than sarcopenia. Phase angle (PhA), a parameter derived from bioimpedance analysis (BIA), provides data on cellular health, membrane integrity, and cellular function. This study aimed to evaluate the relationship between SO and PhA among older adults with type 2 diabetes mellitus (DM). We performed a cross-sectional study in a tertiary hospital, and all participants underwent a comprehensive geriatric assessment, the hand-grip strength test (HGST), the chair stand test (CST) for muscle strength evaluation, the 4-meter walking test, and the timed up-and-go (TUG) test for physical performance assessment. The diagnosis of SO was made according to the ESPEN/EASO criteria. The PhA was determined automatically by the BIA using resistance and reactance at 50 kHz for each participant. A total of 322 participants were included in the study. The mean age of the participants was 72.5 ±5.8, and 203 (63%) of them were female; 63 (19.6%) of them were sarcopenic obese. In multivariable logistic regression analyses, a significant relationship was found when the model was adjusted for age, female gender, MNA-sf scores, HbA1c level, and CCI scores (OR: 0.53, 95%CI: 0.29-0.98, P = 0.04). In ROC analyses, for PhA in predicting SO diagnosis, the AUC was 0.586 (95%CI: 0.505-0.678, P = 0.033). At the cut-off score 4.4, sensitivity was 57.1% and specificity was 61.4%; positive predictive value (PPV) was 26.5%; negative predictive value (NPV) was 85.5%. The study identified a significant relationship between SO and PhA among older adults with type 2 DM. However, larger prospective studies are needed to confirm the potential utility of PhA as a biomarker for SO.

Heart rate dynamics and asymmetry during sympathetic activity stimulation and post-stimulation recovery in ski mountaineers-a pilot exploratory study.

There is a lack of studies on non-linear heart rate (HR) variability in athletes. We aimed to assess the usefulness of short-term HR dynamics and asymmetry parameters to evaluate the neural modulation of cardiac activity based on non-stationary RR interval series by studying their changes during sympathetic nervous system activity stimulation (isometric handgrip test) and post-stimulation recovery in professional ski mountaineers. The correlation between the changes in the parameters and the respiratory rate (RespRate) and also the duration of the career was analyzed. Short-term (5 min) and ultra-short-term (1 min) rates of patterns with no variations (0V), number of acceleration runs of length 1 (AR1), and short-term Porta's Index were greater, whereas Guzik's Index (GI) was smaller during sympathetic stimulation compared to rest. GI increased and the number of AR1 decreased during recovery. Greater increases in GI and RMSSD were associated with greater decreases in RespRate during recovery. Greater increases in RespRate from rest to short-term sympathetic stimulation were associated with greater increases in 0V (Max-min method) and AR1 but also with greater decreases in decelerations of short-term variance and accelerations and decelerations of long-term variance. Greater increases in 0V (Max-min method) and number of AR1 during sympathetic stimulation were associated with a shorter career duration. Greater decreases in these parameters during recovery were associated with a longer career duration. Changes in measures of HR dynamics and asymmetry, calculated based on short-term non-stationary RRi time series induced by sympathetic stimulation and post-stimulation recovery, reflected sympathovagal shift and were associated with condition-related alterations in RespRate and career duration in athletes who practice ski mountaineering.

Household food insecurity is associated with greater autonomic dysfunction testing score in Latinos with type 2 diabetes.

We examined household food insecurity (HFI) and autonomic nervous system (ANS) function in a subset of low-income Latinos with type 2 diabetes with data from a stress management trial. InclusionLatino or Hispanic, Spanish speaking, age less than 18 years, ambulatory status, type 2 diabetes more than 6 months, A1c less than 7.0%. ExclusionPain or dysfunction in hands (e.g., arthritis) precluding handgrip testing; medical or psychiatric instability. HFI was assessed with the 6-item U.S. household food security survey module; with responses to > = 1 question considered HFI. An ANS dysfunction index was calculated from xix autonomic function tests which were scored 0 = normal or 1 = abnormal based on normative cutoffs and then summed. Autonomic function tests were: 1) 24-hour heart rate variability as reflected in standard deviation of the normal-to-normal (SDNN) heart rate acquired with 3-channel, 7-lead ambulatory electrocardiogram (Holter) monitors; 2) difference between the highest diastolic blood pressure (DBP) during sustained handgrip and the average DBP at rest; 3) difference between baseline supine and the minimal BP after standing up; and, from 24-hour urine specimens 4) cortisol, 5) normetanephrine, and, 6) metanephrine. Thirty-five individuals participated, 23 (65.7%) of them were women, age mean = 61.6 (standard deviation = 11.2) years, HbA1c mean = 8.5% (standard deviation = 1.6) and 20 participants (57.1%) used insulin. Twenty-two participants (62.9%) reported HFI and 25 (71.4%) had one or more abnormal ANS measure. Independent t-tests showed that participants with HFI had a higher ANS dysfunction index (mean = 1.5, standard deviation = 0.9) than patients who were food secure (mean = 0.7, standard deviation = 0.8), p = 0.02. Controlling for financial strain did not change significance. Total ANS index was not related to glycemia, insulin use or other socioeconomic indicators. In this sample, HFI was associated with ANS dysfunction. Policies to improve food access and affordability may benefit health outcomes for Latinos with diabetes.

Sarcopenia, sarcopenic obesity, and arterial stiffness among older adults.

Aging is associated with a higher prevalence of sarcopenia, sarcopenic obesity (SO), and increased arterial stiffening, with possible detrimental effects on morbidity and mortality. The aim of this study was to assess the relationships between sarcopenia, SO, and different indexes of arterial stiffness in older adults. A total of 77 hospitalized patients (mean age 78.68 ± 9.65 years) were evaluated, obtaining anthropometric variables, biochemical samples, handgrip test, and body composition assessment. Arterial stiffness was evaluated by measuring both carotid-femoral pulse wave velocity (cfPWV), a proxy for central stiffness, and cardio-ankle vascular index (CAVI), as well as considering peripheral arteries. The population was sorted into four subgroups: obese, sarcopenic, SO, and controls. The highest CAVI (11.31 ± 2.58) was found in sarcopenic patients. SO had the highest value of cfPWV (15.18 ± 8.44 m/s), even after adjustment for significant covariates. In multiple regressions, SO diagnosis resulted as a significant predictor of cfPWV (p = 0.03, R2 = 0.20), and sarcopenia diagnosis resulted as a predictor of CAVI (p = 0.042, R2 = 0.12). In conclusion, a positive correlation is found between sarcopenia, SO, and arterial stiffness among older subjects. In particular, greater central arterial stiffness is associated with SO, outlining a remarkable effect on the cardiovascular risk profile.

Cardiac Autonomic Reactivity Tests in Type A and Type B Personalities.

A considerable link between personality types and cardiovascular diseases (CVDs) has been seen. Autonomic responses in both type A and type B personality individuals were found to be influenced by their personality traits. The study suggests further research on cardiac autonomic functions in larger sample sizes and the use of non-invasive screening techniques like cardiovascular reflex tests to stratify participants' risk of future illness. This study aimed to assess autonomic stress reactivity tests in type A and type B personalities using cardiovascular reflex tests. This study was conducted at the Department of Physiology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi. The Hunter-Wolf Personality Questionnaire Scale was used to identify 60 adults, 30 of whom were classified to have type A personality and 30 have type B personality, from the psychiatry department. Autonomic function tests, such as the handgrip tests, cold pressor test, deep breathing test (DBT), lying-to-standing test (LST), and Valsalva maneuver, were performed and recorded for each subject. IBM SPSS Statistics for Windows, version 21 (released 2012; IBM Corp., Armonk, New York, United States) was used for the compilation and analysis of data. The E:I (expiration-to-inspiration) ratio and delta heart rate of the type A personality patients both significantly decreased (p = 0.000*) as compared to the type B personality patients (1.18 ± 0.03 versus 1.25 ± 0.77 and 1.18 ± 0.03 versus 1.25 ± 0.77). The Valsalva ratio of the type A personality patients decreased (1.38 ± 0.10) as compared to the type B personality patients (1.48 ± 0.18), which was statistically significant (p = 0.001*). The 30:15 ratio in the type A personality patients was significantly decreased (p = 0.03*) compared to the type B personality patients (1.12 ± 0.05 versus 1.15 ± 0.10). The handgrip test and cold pressor test results were statistically insignificant. Compared to the type B personality patients, which exhibited an increase in both parasympathetic and sympathetic reactivity, the type A personality patients exhibited a reduction in resting cardiovascular parameters and resting autonomic tone. Consequently, in order to stratify the participants' risk of future illness, we recommend employing non-invasive procedures, such as cardiovascular reflex tests, as a screening technique.

Gender-Related Effectiveness of Personalized Post-COVID-19 Rehabilitation.

Background: Post-COVID-19 syndrome (PCS) may affect a substantial proportion of patients who have had COVID-19. The rehabilitation program might improve the physical capacity, functioning of the cardiopulmonary system, and mental conditions of these patients. This study aimed to investigate the effectiveness of personalized rehabilitation in patients with PCS according to gender. Methods: Adults who underwent a 6-week personalized PCS rehabilitation program were enrolled in a prospective post-COVID-19 Rehabilitation (PCR-SIRIO 8) study. The initial visit and the final visit included the hand-grip strength test, the bioimpedance analysis of body composition, and the following scales: modified Borg's scale, Modified Fatigue Impact Scale (MFIS), Functioning in Chronic Illness Scale (FCIS), modified Medical Research Council (mMRC) dyspnea scale, and tests: 30 s chair stand test (30 CST), Six-Minute Walk Test (6MWT), Short Physical Performance Battery test (SPPB)e. Results: A total of 90 patients (54% female) underwent the rehabilitation program. Rehabilitation was associated with an increase in skeletal muscle mass (24.11 kg vs. 24.37 kg, p = 0.001) and phase angle (4.89° vs. 5.01°, p = 0.001) and with a reduction in abdominal fat tissue volume (3.03 L vs. 2.85 L, p = 0.01), waist circumference (0.96 m vs. 0.95 m, p = 0.001), and hydration level (83.54% vs. 82.72%, p = 0.001). A decrease in fat tissue volume and an increase in skeletal muscle mass were observed only in females, while an increase in grip strength was noticed selectively in males. Patients' fatigue (modified Borg's scale, MFIS), physical capacity (30 CST, 6MWT), balance (SPPB), dyspnea (mMRC), and functioning (FICS) were significantly improved after the rehabilitation regardless of gender. Conclusions: Personalized rehabilitation improved the body composition, muscle strength, and functioning of patients diagnosed with PCS. The beneficial effect of rehabilitation on body composition, hydration, and phase angle was observed regardless of gender.

Sarcopenia, an overlooked diagnosis inkidney transplant recipients.

Most studies of sarcopenia in renal transplant recipients (RTRs) have been hampered by a lack of standardization in the definitions of sarcopenia. In this study, we aimed to investigate the prevalence of sarcopenia and the associated factors in RTRs using the recently proposed criteria of the European Working Group on Sarcopenia in Older People 2018 (EWGSOP2), which included a standardized definition of sarcopenia. We examined 93 consecutive adult RTRs, 46 chronic kidney disease patients, and 46 healthy controls. We assessed the muscle strength with a hand grip test using a dynamometer and with a chair stand test. We used bioimpedance analysis to estimate appendicular skeletal mass using the Sergi formula. Finally, we conducted a 2-minute walking test to assess endurance. Sarcopenia and probable sarcopenia were determined according to the revised criteria of the EWGSOP2. Probable sarcopenia was found in 29 RTR patients (31.2%), of them 14 (15.1%) were diagnosed with sarcopenia. Multivariate logistic regression analysis showed that presence of diabetes mellitus, increased uric acid level, and statin use were risk factors for probable sarcopenia. On the other hand, longer dialysis vintage was a risk factor for sarcopenia in RTRs. We found that probable sarcopenia and sarcopenia were highly prevalent in our relatively young RTRs. We recommend active screening for the presence of sarcopenia in RTRs, especially in the cadaveric ones. Furthermore, caution seems warranted regarding the myopathic side effects in RTRs who use statins.

Cognitive hallmarks of insomnia and its influence on cardiac response to handgrip test among medical students

Background: Sleep disturbance, particularly insomnia, is increasingly prevalent among university students, and is associated with risk of cardiovascular disease in general population. The study investigated predictors of insomnia and its impact on cardiovascular responsiveness among undergraduates at the University of Lagos, Nigeria. Methods: A cross-sectional survey was conducted on 514 students categorized into normal or insomnia groups based on their insomnia severity index (ISI) scores. The association between insomnia and various factors related to poor sleep was assessed. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) responses to a handgrip test at 30% maximum voluntary contraction (MVC) were compared between the two groups (n=27) using t-tests. Results: Predictors of insomnia among students included environmental discomfort, engagement in digital activities, emotional and health challenges, use of sleep suppressants, and academic stress, all significantly associated with insomnia (p&lt;0.001). Other factors associated with insomnia included low mood, attention deficit, memory loss, and poor academic performance (p&lt;0.01). Average SBP and DBP were significantly higher (p&lt;0.05) in control group compared with insomnia group. Conclusions: Low mood, attention deficit, memory loss and poor academic performance are hallmarks of insomnia among medical students, with no potential cardiovascular risk.

Results of current study revealed that significant improvement of Bench Press and Hand-Grip strength tests between pre-intervention and post-intervention (p&amp;lt;0.05). Conclusions: The para elite athletes from Vietnam, in the case of the elite sporting environment where small changes in their performance often represent a meaningful difference for performance outcomes, informed decisions surrounding the context of post-training recovery services is of utmost importance.

Physical and autonomic functionality in women with breast cancer pre and post chemotherapy: a case control study

BackgroundBreast cancer (BC) is one of the most incident types of cancer among women in the world. Although chemotherapy is an effective way to treat several types of cancer, it may also cause serious complications, including cardiotoxicity. This study aimed to identify the impact of chemotherapy on functional capacity, muscle strength and autonomic function.MethodsTen breast cancer patients in therapeutic follow-up (TG) and ten women without comorbidities (CG) participated in the study (46±8.87 years old). Both groups were evaluated at two time points, before and 20 weeks after the start of chemotherapy. Functional capacity and muscle strength were assessed by 6-minute walk test (6MWT) and handgrip test, respectively. Autonomic function was assessed by heart rate variability analysis.ResultsTG presented greater reductions in the handgrip test for the non-dominant hand (TG ↓15.2%; CG: ↑1.1%, p<0.05) compared to GC. However, no significant differences were found regarding VO2max (p>0.05) and 6MWT total distance (p>0.05). Regarding the heart rate variability variables before and after follow-up period, rMSSD (CG= 39.15±37.66; TG= 14.89±8.28, p= 0.01) and SDNN (CG= 55.77±40.03; TG= 26.30±10.37, p= 0.02) showed effect in the group and time interaction, whereas the LF/HF ratio presented significant difference only in the time analysis (CG= 2.24±2.30; TG= 2.84±1.82, p= 0.04).ConclusionChemotherapy used in the treatment of breast cancer patients resulted in decreased muscle strength and autonomic imbalance. The data suggests that chemotherapy may carry the risk of developing cardiovascular disease.Trial registrationRegistration not required.

Monitorovanie funkčného stavu ako prostriedok prevencie komplikácií u geriatrických pacientov

Introduction: The geriatric patient is included in the category of patients with the highest risk of complications. In the case of institutional treatment, his nutritional status and self-sufficiency may deteriorate, he may decompensate for a chronic disease, he may develop geriatric frailty syndrome, sarcopenia, etc. Therefore, it is necessary to identify health problems and functional limitations of seniors as soon as possible, ideally at the time of their reversibility. Areas that require special attention because they affect the overall health and psychological state of the patient include nutrition, physical fitness and the ability to perform activities of daily living. Objective: The main goal of the research was to point out the benefit of regular monitoring of the functional status of geriatric patients in institutional treatment. The partial goal was to find out the current state of nutrition, physical activity and self-sufficiency in geriatric patients. To find out how the state of nutrition, physical activity and self-sufficiency changes after the intervention by members of the interdisciplinary team. Methodology: The research methods were nutritional anamnesis, standardized measuring tools Mini Nutritional assessment (MNA), MNA-Short-Form (MNA-SF), Barthel test (ADL), Physical fitness test (SARS-F), Hand-grip test and additional methods - analysis of health documentation, anthropometric measurements and physical examination. the research set were geriatric patients in institutional health and social facilities (SF). The total number was 368, of which 114 were men, 254 were women. of that number, 132 respondents were hospitalized in the health care facilities (HCF) and 236 in SSF in the Slovak and czech Republics. Research results: We identified risk factors for malnutrition during the nutritional anamnesis. The most common were difficulties with swallowing (n 46), reduced appetite (n 30), a feeling of fullness (n 29), but also problems with excretion- constipation (n 64). Other risk factors were polypharmacy - 105 patients, use of risky medication (n 67), oncological treatment. The average values of the screening tools were: BMI- 26.74, MNA- 23, MNA-SF- 6.3, SARS-F- 3.38, ADL- 74.5, Hand grip test 8.3. Patients in the HcF had worse nutritional status - 41 had malnutrition and 75 patients were at risk of malnutrition. A very negative result was the average value of Hand grip and physical fitness test. Patients had presarcopenia and sarcopenia. Statistical data processing confirmed the relationship between MNA and ADL, SARS-F values (correlation 0.01, 0.05). MNA values had an impact on patients‘ level of self-sufficiency and physical fitness. After the identification of the problem, 356 patients had implemented appropriate interventions - dietary modification, sipping, education, enteral and partially parenteral nutrition, rehabilitation, nursing rehabilitation. After repeated monitoring, the values were adjusted. However, the SARS-F values were not adjusted, nor was the grip strength of seniors in SSF. Conclusion: Regular monitoring of the functional status of geriatric patients has its justification. Thanks to the screening tools, we identified patients at risk of malnutrition and sarcopenia and subsequently eliminated the complications related to them. The research results are part of the KEGA project no. 009 KU-4/2022 Nutrition and physical activity as basic pillars of care for patients at risk.

Força de preensão manual na doença de Parkinson: uma revisão sistemática de estudos observacionais

Abstract Introduction People with Parkinson’s disease may pre-sent muscle weakness. The handgrip test is used to identify upper limbs strength. There are different protocol descriptions of this assessment. Objective To carry out a systematic review on the assessment of handgrip strength in people with Parkinson’s. Methods The review was carried out according to the PRISMA guidelines, the PubMed, SciELO, LILACS and Scopus literary databases, and registered at PROSPERO (CRD420201 9018). Quantitative analysis was performed using the Newcastle-Ottawa Scale. Twenty-seven articles were analyzed. Results The most referenced protocol is that of the American Society of Hand Therapists. The most used instrument is the hydraulic dynamometer. Of the sixteen studies that compared handgrip strength be-tween people with Parkinson’s and healthy people, seven identified a statistically significant difference. No article was classified as unsatisfactory. Conclusion It is not possible to affirm that handgrip strength is reduced in Parkinson’s disease, when compared to healthy subjects. Protocol and instrument standardization can help com-parisons between results from different studies. There are few longitudinal studies, making it difficult to under-stand what happens to handgrip strength as the disease progresses.

Effect of combined hormone replacement therapy on sympathetic nervous system function in postmenopausal women – A cross-sectional study

Background: There is an increased prevalence of cardiovascular and metabolic diseases in postmenopausal women. Estrogen plays an important role in the regulation of blood pressure (BP) and autonomic function. Various hormone therapies are widely used in postmenopausal women, especially combination therapy of low-dose estrogen and progesterone. Hormone therapy might be useful not only in alleviating menopausal symptoms but help in reducing cardiovascular risk factors and improving quality of life. Aims and Objectives: The aim of the study is to study the effect of combined estrogen and progesterone hormone therapy on BP and sympathetic overactivity in postmenopausal women. Materials and Methods: The study included two groups of 50 women each. Group I included postmenopausal women of age 45–55 years who were taking combined hormone therapy while Group II included postmenopausal women of the same age group who were not on any replacement therapy heart rate and BP in resting state was noted in both the groups. Sympathetic function assessment was done by performing cold pressor test, handgrip test, and BP response to standing on all the participants. Statistical analysis was done using the student’s t-test. Results: There was a statistically significant difference in resting heart rate, BP, and sympathetic function tests in both groups. Conclusion: There is a facilitatory role of combined estrogen and progesterone therapy in menopausal women in reducing BP and sympathetic system dysregulation.

Association between body mass index, muscle-to-fat ratio, and handgrip strength-to-BMI ratio with physical fitness in children from North Macedonia.

this cross-sectional study, conducted on a convenience sample of 2197 Macedonian primary school children, aimed to examine how certain anthropometric indices (body mass index (BMI), muscle-fat ratio (MFR), hand grip strength-BMI ratio) are related to the physical fitness of individuals. the sample was split into two groups based on gender: 1096 boys and 1101 girls (average age 8.1 ± 1.3 years). Data on anthropometric measurements (BMI, MFR) were taken and the physical fitness was measured with the following tests: sit and reach, handgrip strength, standing long jump, sit-ups 30 sec., shuttle run 4 x 10 m, and 20 meters shuttle-run test (20-mSRT). the findings from the study indicate that children with normal weight exhibit superior levels of cardiorespiratory, muscular, and motor fitness in comparison to those who are categorized as obese, irrespective of gender. Both muscle‑to‑fat ratio (MFR), and grip strength-to-BMI ratio showed correlation with most fitness tests. Grip strength-to-BMI ratio showed a positive correlation with the results of the handgrip test in boys and girls. in this population, BMI, MFR, and handgrip strength-to-BMI ratio can serve as indicators of health and physical fitness.
