“…Regarding the criteria of the EWGSOP2, the JAMAR ® dynamometer has been used for the evaluation of muscle strength; this is a validated and widely used instrument, however, it requires data from appropriate reference populations [1]. It is a common, easy and reproducible method, that does not require the intervention of the examiner and has adjustable handles with five different positions, with the second position being the most recommended to perform the assessment of maximum muscle strength [15]. Evidence shows that muscle strength begins to decline gradually after turning 50 years old [15].…”

“…Muscle strength: It was assessed by the measurement of grip strength using a JAMAR ® hydraulic handheld dynamometer, which measures from 0 to 200 lbs or 90 kg and has 5 grip positions. The technique for measuring strength considered the subject seated in a chair with the back against the backrest, shoulders adducted with no rotation, elbow flexed at 90 • , forearm and wrist in a neutral position, feet flat on the floor, the evaluated arm should not be resting on any surface, the dynamometer must be placed vertically and the second position should be used; maximum grip strength was measured for 3 seconds, resting 1 minute between each repetition, performing 2 attempts [15,16]. The dominant hand was used [17,18].…”

Association between Sarcopenia and Nutritional Status in Chilean Older People Aged 65 Years and Older

2022

In 2018 the European Working Group on Sarcopenia in Older People (EWGSOP2) updated the definition of sarcopenia, with loss of muscle strength being the primary feature. The objective is to describe and associate sarcopenia and nutritional status in a group of Chilean older adults aged 65 years and older. Methods: Descriptive, associative and comparative study, with a cross-sectional design and a quanti-qualitative approach. A number of 155 institutionalized and community-dwelling Chilean older people aged 65 years and older participated in the study (year 2018). Sarcopenia was diagnosed using the algorithm proposed by the EWGSOP2. Muscle strength, muscle quantity and physical performance were assessed; Body Mass Index (BMI) and Mini Nutritional Assessment (MNA) were used. Variables were described according to sex and age groups (65–69; 70–79; and ≥80 years). The association between sarcopenia and nutritional status was studied by the application of multivariate logistic regression analysis with adjustments for age and sex. Results: 49.7% and 5.2% of older adults had probable sarcopenia and severe sarcopenia, respectively; 52.9% and 7% had malnutrition by excess and by deficit, respectively, according to their BMI; and 33.5% had malnutrition according to the MNA. Participants with obesity had 3.2 times more risk of presenting sarcopenia, versus subjects with normal nutritional status (OR: 3.2; 95% CI; 1.24; 8.26). Conclusion: Sarcopenia, as defined by the criteria of the EWGSOP2, depends on the nutritional status according to BMI in older people, with obese individuals being at greater risk of suffering from sarcopenia. Nearly 50% had probable sarcopenia, a condition that could be detected early with the purpose of taking preventive measures, such a nutritional approach.

“…Intra-instrument reliability and concurrent validity were tested using certified standard weights (r = 1.00), while inter-instrument reliability was good, between 0.80 and 0.83 ( 56 ). Further, there are reference values for a healthy Chilean population ( 57 , 58 ).…”

Effect of Supervised Resistance Training on Arm Volume, Quality of Life and Physical Perfomance Among Women at High Risk for Breast Cancer-Related Lymphedema: A Study Protocol for a Randomized Controlled Trial (STRONG-B)

et al. 2022

View full text Add to dashboard Cite

ObjectivesTo determine the preventive effects of supervised resistance training on arms volume, quality of life, physical performance, and handgrip strength in Chilean women at high risk for breast cancer-related lymphedema (BCRL) undergoing chemotherapy.DesignRandomized control trial.ParticipantsOne hundred and six women at high risk for breast cancer-related lymphedema aged 18 to 70 years.InterventionsParticipants will be randomized into two groups: [a] intervention, who will receive 12 weeks of supervised resistance training (STRONG-B) during adjuvant chemotherapy; and [b] control, who will receive education to promote lymphatic and venous return, maintain range of motion, and promote physical activity.Main Outcome MeasuresThe primary outcome will be arms volume measured with an optoelectric device (perometer NT1000). Secondary outcomes will be quality of life, handgrip strength, and physical performance. Primary and secondary outcomes will be measured at baseline, just after the intervention, and 3 and 6 months after. Statistical analysis will be performed following intention-to-treat and per-protocol approaches. The treatment effect will be calculated using linear mixed models.DiscussionThe STRONG-B will be a tailored supervised resistance training that attempts to prevent or mitigate BCRL in a population that, due to both intrinsic and extrinsic factors, will commonly suffer from BCRL.Clinical Trial Registration[https://clinicaltrials.gov/ct2/show/NCT04821609], identifier NCT04821609.

Sexual, physical, mental and sleep sequelae four months after SARS-CoV-2 diseaseBackground: Long term sequelae can be observed after SARS-CoV2. Aim: To describe the sexual, physical, mental and sleep sequelae four months after SARS-CoV2 diagnosis. Patients and Methods: Patients recovering from SARS-CoV2 with different degrees of disease severity were consecutively included and separated in two study groups, namely Group 1 including patients that had an acute respiratory distress syndrome (ARDS) and Group 2 including those with mild or moderate COVID-19. Handgrip strength, respiratory polygraphy (RP), Quality of life using the SF-12 questionnaire, and the international index of erectile (IIEF-5) function were assessed. Results: Twenty patients who had ARDS, and 10 without ARDS were included. Erectile dysfunction was observed in 77 and 10% of patients with and without ARDS, respectively (p < 0.01). The figures for sleep obstructive apnea were 82 and 40% respectively (p = 0.02) and for the physical domain SF-12 score were 39.2 and 47.9 points respectively (p = 0.01). No differences in muscle strength were observed. After a multivariable analysis, previous ARDS due to COVID-19 was independently associated with erectile dysfunction, with an odds ratio of 30.6 (95% confidence intervals, 3.08-300.3, p = 0.003). Conclusions: Among men with ARDS due to COVID-19, the prevalence of erectile dysfunction was high and independently associated with a severe disease four months after discharge.
