A multidimensional approach to the resilience in older adults despite COVID-19.

Researchers have mainly focused on aging risk factors and COVID-19 consequences. However, older adults have proved their ability to overcome adversities along their life. Resilience is a protective variable that dampens the impact of stress. Based on MacLeod's et al. (2016) approach, we aimed to analyze the relationship between older adults' resilience and COVID-19 related-stressors as well as their physical, mental, and social characteristics. Eight hundred eighty-nine people aged 60 and over participated in this study. Older participants, women, having better perceived health and not losing a loved one because of the virus were associated with more resilience. Moreover, higher levels of gratitude, personal growth, life purpose and lower levels of depression were associated with greater scores in resilience. This study offers a change of perspective in which aging is perceived from a positive viewpoint by focusing on easily accessible resources that may help older adults to cope with adverse situations.

When to use a prophylactic mesh after stoma closure: a case-control study.

PURPOSE: The closure of a stoma is frequently associated with an acceptable morbidity and mortality. One of the most frequent complications is incisional hernia at the stoma site, which occurs in 20%-40% of cases, higher than incisions in other parts of the abdomen. The objective of this study was to identify the risk factors associated with the presentation of incisional hernia after stoma closure, this in order to select patients who are candidates for prophylactic mesh placement during closure. METHODS: An unpaired case-control study was conducted. This study involved 164 patients who underwent a stoma closure between January 2014 and December 2019. Associated factors for the development of incisional hernia at the site of the stoma after closure were identified, for which it was performed a logistic regression analysis. RESULTS: 41 cases and 123 controls were analyzed, with a mean follow-up of 35.21 ± 18.42 months, the mean age for performing the stoma closure was 65.28 ± 14.07 years, the most frequent cause for performing the stoma was malignant disease (65.85%). Risk factor for the development of incisional hernia at the stoma site after its closure was identified as a history of parastomal hernia (OR 5.90, CI95% 1.97-17.68). CONCLUSIONS: The use of prophylactic mesh at stoma closure should be considered in patients with a history of parastomal hernia since these patients present a significantly higher risk of developing a hernia.

Psychological well-being among older adults during the COVID-19 outbreak: a comparative study of the young-old and the old-old adults.

The COVID-19 outbreak could be considered as an uncontrollable stressful life event. Lockdown measures have provoked a disruption of daily life with a great impact over older adults' health and well-being. Nevertheless, eudaimonic well-being plays a protective role in confronting adverse circumstances, such as the COVID-19 situation. This study aims to assess the association between age and psychological well-being (personal growth and purpose in life). Young-old (60-70 years) and old-old (71-80 years) community-dwelling Spaniards (N = 878) completed a survey and reported on their sociodemographic characteristics and their levels of health, COVID-19 stress-related, appraisal, and personal resources. Old-old did not evidence poorer psychological well-being than young-old. Age has only a negative impact on personal growth. The results also suggest that the nature of the COVID-19 impact (except for the loss of a loved one) may not be as relevant for the older adults' well-being as their appraisals and personal resources for managing COVID-related problems. In addition, these results suggest that some sociodemographic and health-related variables have an impact on older adults' well-being. Thus, perceived-health, family functioning, resilience, gratitude, and acceptance had significant associations with both personal growth and purpose in life. Efforts to address older adults' psychological well-being focusing on older adults' personal resources should be considered.

[Posttraumatic growth in parents of children and adolescents with cancer]. / Crecimiento postraumático en padres de niños y adolescentes con cáncer.

Cancer can provoke negative psychological reactions. Nevertheless, coping with oncological issues can also result in positive psychological changes that demonstrate the strength of the human being, one of them being posttraumatic growth (PTG). The aim of this narrative review was to examine and analyze studies, published from 2000 to 2018 and available in different data sets, that focus on PTG in parents of children and adolescents with cancer in the pediatric context. Twenty studies were identified, including 2,422 subjects, mainly mothers (n=1,788). PTG was analyzed according to the differences among relatives, outcome and type of oncological disease, and its predictor factors. Fathers and mothers are both capable of developing PTG as a result of their children's disease, mothers being the ones who present higher levels. Compared with other samples like parents of children with type I diabetes or healthy children, or adult patients with osteosarcoma, parents of children with cancer present more PTG. Likewise, factors that influence the development of PTG, such as cultural context, cognitive processing, adjustment to the disease and certain personality traits are observed. The published clinical evidence endorses the existence of PTG in parents of children with cancer. However, it would be necessary to carry out further investigation, particularly subjective and longitudinal studies with larger homogeneous samples, in order to design interventions aimed at promoting PTG and avoid focusing solely on the negative aspects of oncological disease in children.

Crecimiento postraumático en padres de niños y adolescentes con cáncer / Posttraumatic growth in parents of children and adolescents with cancer

El cáncer puede provocar reacciones psicológicas negativas. No obstante, la lucha al abordar los problemas oncológicos también puede dar lugar a cambios psicológicos positivos que demuestran la fortaleza del ser humano, siendo una de ellas el crecimiento postraumático (CPT). El objetivo de esta revisión narrativa fue revisar y analizar los artículos, publicados durante los años 2000 a 2018 y disponibles en distintas bases de datos, sobre el CPT en padres y madres de niños y adolescentes con cáncer en el ámbito pediátrico. Se identificaron 20 estudios que incluían 2.422 sujetos, mayoritariamente madres (n=1.788), y que analizaban el CPT en función del parentesco, evolución y tipo de enfermedad del hijo, así como factores predictores del mismo. Tanto padres como madres, son capaces de desarrollar CPT como consecuencia de la experiencia del cáncer de sus hijos, siendo ellas quienes experimentan mayores niveles. En comparación con otras muestras como progenitores de niños con diabetes tipo I o de niños sanos, o pacientes adultos con osteosarcoma, los padres y madres de niños con cáncer refieren mayor CPT. Asimismo, se observan factores que influyen en el desarrollo del CPT, como el contexto cultural, el procesamiento cognitivo, el ajuste a la enfermedad y ciertos rasgos de personalidad. La evidencia científica publicada avala la existencia de CPT en madres y padres de hijos con cáncer. No obstante, sería necesario realizar estudios objetivos, longitudinales, con muestras homogéneas de mayor tamaño, para diseñar intervenciones dirigidas a promocionar ese CPT y no centrarse solo en los aspectos negativos de la enfermedad

Development and assessment of the content validity of the professional good practices scale in nursing homes.

Recent approaches in the care of older people have led to a greater emphasis on good practices to prevent elder abuse. The instruments assessing good practices are very limited, and those focused on elder abuse have rarely considered subtle forms, especially in institutional settings. The aim of this study was to develop and assess the content validity of a good practices scale for professionals working in nursing homes. An extensive literature review of the tools assessing professionals' good-bad practices towards older people was conducted. A preliminary scale based on Kayser-Jones' (1990) [Old, Alone and Neglected: Care of the Aged in Scotland and the United States. Berkeley, CA: University of California Press] types of abuse was developed, including four subscales: Personalization, Humanization, Absence of Infantilization, and Absence of Victimization. Content validity was analyzed through a panel of eight experts. Rovinelli and Hambleton's index of item-objective congruence was used to analyze the items' inclusiveness in the assigned subscale to establish their representativeness. Items' relevance and clarity were analyzed using the paired comparison method. The final version of the scale included 56 items, with appropriate levels of item objective-congruence, relevance, and clarity. This instrument will allow professionals to detect and develop awareness and intervention programs that aim to promote good practices in nursing homes.

Elbow Joint Angle Estimation with Surface Electromyography Using Autoregressive Models.

This paper presents a method to estimate the elbow joint angle from surface electromyography (sEMG) measurements of biceps, triceps and brachioradialis. This estimation is of major importance for the design of human robot interfaces based on sEMG. It is also relevant to model the muscular system and to design biomimetic mechanisms. However, the processing and interpretation of electromyographic signals is challenging due to nonlinearities, unmodeled muscle dynamics, noise and interferences. In order to determine an estimation model and a calibration procedure for the model parameters, a set of experiments were carried out with six subjects. The experiments consisted of series of continuous (cyclical) and discrete elbow flexo-extensions with three different loads (i.e. 0 kg, 1.5kg and 3 kg). The sEMG data from the biceps brachii, triceps brachii and brachioradialis and the joint angle were recorded. Four different modeling techniques were evaluated: State Space (SS), Autoregressive with Exogenous Input (ARX), Autoregressive Moving-Average with Exogenous Input (ARMAX), Autoregressive Integrated Moving-Average with Exogenous Input (ARIMAX). After the model was selected, a second experiment was performed in order to validate the estimation procedure. The results show a procedure to estimate the EMG-to-angle relation with high correlation and low meansquare- root errors with respect to the measured angle data.

Biomechanical procedure to assess sleep restriction on motor control and learning.

The analysis of sleep quality during long periods and its impact on motor control and learning performance are crucial aspects for human health. The aim of this study is to analyze effects of chronic sleep restriction on motor performance. It is intended to establish motor control indicators in sleep quality analysis. A wearable actigraphy that records accelerometry, ambient light, and body temperature was used to monitor the sleep habits of 12 healthy subjects for two weeks before performing motor control and learning tests. The day of the motor test, the subjects filled two questionnaires about the quality of sleep (Pittsburgh Sleep Quality Index - PSQI) and sleepiness (Epworth Sleepiness Scale - ESS). Afterwards they performed a coincident timing task that consisted of hitting a virtual target falling on the screen with the hand. An elbow flexion in the horizontal plane had to be performed on the correct time to reach the real target on a table at the same time as the virtual target on the screen. The subjects performed three sets of acquisition and transfer blocks of the coincident timing task. The subjects were clustered in two groups based on the PSQI and ESS scores. Actigraphy and motor control parameters (L5, correct responses, time variance) were compared between groups and experimental sets. The group with better sleep parameters did show a constant performance across blocks of task acquisition while the bad sleeper group improved from the first to the second acquisition block. Despite of this improvement, their performance is not better than the one of the good sleepers group. Although the number of subjects is low and it should be increased, these results indicate that the subjects with better sleep converged rapidly to a high level of performance, while the worse sleepers needed more trials to learn the task and their performance was not superior to the other group.

Posttraumatic Growth in Widowed and Non-widowed Older Adults: Religiosity and Sense of Coherence.

Older people may experience psychological growth following a life major event. The objective of this study is to analyze the degree of posttraumatic growth (PTG) developed by widowed and non-widowed older adults (n = 103) as well as the impact of possible predicting variables such as sociodemographic characteristics, experienced or witnessed life major events, religiosity and sense of coherence. The findings suggest that, in spite of widowhood, elder people develop PTG in the same way that non-widowed elder people. Therefore, the support of a religious community, age, life major events experienced and the subjective meaning given to them correlated with PTG.

Recurrent group A streptococcal tonsillopharyngitis.

OBJECTIVE: To examine the epidemiology and treatment of group A beta-hemolytic streptococcal (GABHS) recurrent tonsillopharyngitis in private pediatric practice. METHODS: This was a retrospective chart review study covering the time span 1975 to 1996 involving 2140 GABHS episodes. Diagnosis was based on acute clinical symptoms and laboratory confirmation (throat culture or positive rapid antigen detection test) of GABHS. RESULTS: Eighty percent (n=1721) of the episodes evaluated were treated with penicillin or amoxicillin; 352 (20.5%) of these were followed by a recurrence within 30 days and 519 (30.2%) within 60 days. GABHS recurrences within 30 days after penicillin/amoxicillin treatment rose from 9% in 1975 to 1979 to 25.9% in 1980 to 1984, 24.2% in 1985 to 1989, 22.4% in 1990 to 1994 and 25.9% in 1995 to 1996 (P < 0.02); 53.4% of the recurrences were associated with symptoms and signs of GABHS tonsillopharyngitis, 9.9% were asymptomatic and 36.7% could not be classified. Recurrences within 60 days after penicillin/ amoxicillin treatment rose from 10.7% in 1975 to 1979 to 38.7% in 1980 to 1984, 39.0% in 1985 to 1989, 31.7% in 1990 to 1994 and 37.5% in 1995 to 1996 (P < 0.001). Recurrent GABHS infections occurred more frequently in younger children (1 to 8 years of age, 21.3% recurrence rate) than in adolescents (13 to 19 years, 5% recurrence rate; P=0.002). Recurrences within 30 days occurred more often after therapy with penicillin (21.8% of 1581 episodes) than with cephalosporins (8.6% of 254 episodes) (P < 0.0001) or with macrolides (14.0% of 143 episodes, P=0.04). Recurrence rates were unaffected by patient gender or season of the year. CONCLUSIONS: Recurrent GABHS infections occur more frequently in the 1990s than the 1970s, occur more frequently in children younger than 8 years of age than in adolescents and occur more frequently after penicillin treatment than with alternative antibiotic therapy.

[Sporothrix schenckii: cultures in different soils]. / Sporothrix schenckii: cultivos en diferentes suelos.

In order to establish the conditions of temperature, pH, and organic material which favor the development of Sporothrix schenkii, the cultures of this fungus were examined in media consisting of potting soil, clay, white land and sand. The results indicate that the content of organic material in the soils is fundamental for mycelium development. The fungus shows growth in the soils rich in cellulose in the pH range from 3.5 to 9.4 and temperature of 31 degrees C. the development of the mycelium does not show alterations in phenotypical characteristics. These results show the distributions that S. schenkii can have in the soils, which can be transmission vehicles of sporotrichosis.

[Incidence of Chlamydia trachomatis in patients with sterility]. / Incidencia de Chlamydia trachomatis en pacientes con esterilidad.

Eighty six women were studied at the Hospital Chiquinquirá in order to determine the role of Chlamydia Trachomatis in infertility. Endocervical samples were taken in 45 infertile women (IG) who concurred to our Gynecologic Endocrinology Clinic and in 41 (CG) who sought medical attention at our General Gynecology Clinic for different reasons. The Chlamydiazyme Test (CT) was performed in all of them. We obtained 12 positive Chlamydiazymes (13.95%), four of them were in the IG (8.89%) and 8 (19.5%) in the CG; this was not statistically significant (p = 0.3). We also found no correlations when positive tests were correlated with sterility (p = 0.5, tube pathology history (p = 0.2), HSG (p = 0.2) and laparoscopic findings (p = 0.1). We did not find an increase in the occurrence of CT in our infertile women as reported by other authors therefore its significance in our study group at this time is uncertain.
