Bichectomy Surgery and EMG Masticatory Muscles Function in Adult Women: A Longitudinal Study.

AIM: This longitudinal study aimed to evaluate the electromyographic activity of the masseter and temporal muscles in adult women who underwent buccal fat removal. MATERIALS AND METHODS: The sample consisted of 20 healthy adult women with no temporomandibular dysfunction and normal occlusion, who were assessed before, 30, and 60 days after the surgery. The electromyographic signal of the masseter and temporal muscles was captured through mandibular tasks including rest, protrusion, right and left laterality, and maximum voluntary contraction with and without parafilm. The results obtained were tabulated and the Shapiro-Wilk normality test was performed, which indicated a normal distribution. Statistical analysis was performed using the repeated measures test (p < 0.05). RESULTS: Significant differences were observed between time periods in maximum voluntary contraction for the left masseter muscle (p = 0.006) and in maximum voluntary contraction with parafilm for the right temporal (p = 0.03) and left temporal (p = 0.03) muscles. CONCLUSION: Bichectomy surgery did not modify the electromyographic activity of the masseter and temporal muscles during the rest task but may have influenced variations in the electromyographic signal during different mandibular tasks after 60 days of surgery, suggesting compensatory adaptations and functional recovery. CLINICAL SIGNIFICANCE: Understanding the impact of buccal fat removal surgery on the stomatognathic system function provides insights into postoperative functional recovery and potential compensatory adaptations, guiding clinical management and rehabilitation strategies for patients undergoing such procedures.

O sono na pandemia COVID-19 e influência na saúde mental na população infantil e pediátrica / Sleep in the COVID-19 pandemic and its influence on mental health in the infant and pediatric population

Introdução: A pandemia COVID-19 e medidas associadas provocaram alterações na qualidade e quantidade do sono, com impactos na saúde mental. Objetivos: Compreender como a pandemia e o confinamento interferiu nas rotinas e/ou hábitos de sono em crianças e adolescentes e a influência na saúde mental. Metodologia: Revisão da literatura na MEDLINE, partindo da questão: Quais são as alterações nas rotinas ou hábitos de sono em crianças e adolescentes durante a pandemia? Resultados e discussão: Dos 370 artigos, foram selecionados 35. Devido ao confinamento e o ensino à distância, a quantidade de horas de sono aumentou. Porém, com a diminuição da atividade física, desequilíbrio alimentar e aumento do tempo frente aos ecrãs a qualidade do sono diminuiu. Consequentemente, verificou-se uma influência negativa na saúde mental. Conclusão: Verificou-se o aumento dos distúrbios de sono e sua influência na saúde mental, com necessidade de desenvolvimento de estratégias de consciencialização e literacia na temática. (AU)

Introduction: The COVID-19 pandemic and preventive measures led to changes in the quality and quantity of sleep, impacting mental health. Objectives: To understand how the pandemic and confinement interfered with the routines and/or sleeping habits of children and adolescents and influenced mental health. Methodology: A literature review on MEDLINE was conducted, with the research question: What are the changes in the routines or sleep habits of children and adolescents during the pandemic? Results and discussion: From the 370 articles analysed, 35 were selected. Due to confinement and online learning, the number of hours of sleep increased. However, the quality of sleep decreased due to decreased physical activity, an unbalanced diet, and increased time in front of screens. Consequently, there was a negative influence on mental health. Conclusion: The increase in sleep disorders and their influence on mental health was observed, with the need to develop awareness and literacy strategies addressing this area. (AU)

Symptom clusters and survival in Portuguese patients with advanced cancer.

This study aimed to identify clusters of symptoms, to determine the patient characteristics associated with identified, and determine their strength of association with survival in patients with advanced cancer (ACPs). Consecutively eligible ACPs not receiving cancer-specific treatment, and referred to a Tertiary Palliative Care Clinic, were enrolled in a prospective cohort study. At first consultation, patients rated 9 symptoms through the Edmonton Symptom Assessment System (0-10 scale) and 10 others using a Likert scale (1-5). Principal component analysis was used in an exploratory factor analysis to identify. Of 318 ACPs, 301 met eligibility criteria with a median (range) age of 69 (37-94) years. Three SCs were identified: neuro-psycho-metabolic (NPM) (tiredness, lack of appetite, lack of well-being, dyspnea, depression, and anxiety); gastrointestinal (nausea, vomiting, constipation, hiccups, and dry mouth) and sleep impairment (insomnia and sleep disturbance). Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter survival was observed for patients with the NPM cluster (58 vs. 23, P < 0.001), as well as for patients with two or more SCs (45 vs. 21, P = 0.005). In a multivariable model for survival at 30-days, age (HR: 0.98; 95% CI: 0.97-0.99; P = 0.008), hospitalization at inclusion (HR: 2.27; 95% CI: 1.47-3.51; P < 0.001), poorer performance status (HR: 1.90, 95% CI: 1.24-2.89; P = 0.003), and NPM (HR: 1.64; 95% CI: 1.17-2.31; P = 0.005), were associated with worse survival. Three clinically meaningful SC in patients with advanced cancer were identifiable. The NPM cluster and the presence of two or more SCs, had prognostic value in relation to survival.

[Pain Intensity and Time to Death of Cancer Patients Referred to Palliative Care]. / Associação da Intensidade de Dor no Tempo Até à Morte dos Doentes Oncológicos Referenciados aos Cuidados Paliativos.

INTRODUCTION: Pain is a common symptom experienced by cancer patients, especially in those with advanced disease. Our aim was to describe pain intensity in advanced cancer patients, referred to the palliative care unit, the factors underlying moderate to severe pain and its prognostic values. MATERIAL AND METHODS: This was a prospective observational study. All patients with mestastatic solid tumors and with no specific oncologic treatment were included. Pain intensity was accessed using the pain scale from Edmonton Symptom Assessment Scale, rated from 0 to 10 on a numerical scale, where zero = no pain and 10 = worst possible pain. RESULTS: Between October 2012 and June 2015, a total of 301 patients participated in the study. The median age was 69 years, (37 - 94); most of the patients were men (57%) and 64.8% had a performance status of 3/4. About 42% reported pain severity ≥ 4 and 74% were medicated with opioids. Multivariate analysis indicated a correlation between performance status and reported pain (OR: 1.7; IC 95%: 1.0 - 2.7; p = 0.045). Median overall survival was 37 days (IC 95%: 28 - 46). Patients reporting moderate to severe pain (pain severity ≥ 4) had a median survival of 29 days (IC 95%: 21 - 37), comparing with those who had no or moderate pain with median survival of 49 days (IC 95%: 35 - 63) (p = 0.022). DISCUSSION: The performance status was associated with more intense pain. The performance status, hospitalization, intra-abdominal metastization and opioid analgesia were associated with shorter time to death in advanced cancer patients referred to palliative care. CONCLUSION: Cancer pain continues to be a major clinical problem in advanced cancer patients.

Introdução: A dor é uma experiência frequente nos doentes com cancro, especialmente naqueles em fase final de vida. Com este estudo, pretendemos estudar a intensidade de dor nos doentes com cancro avançado, referenciados aos cuidados paliativos, analisar os factores associados à ocorrência de dor moderada ou intensa e avaliar a sua relação com o tempo até à morte destes doentes. Material e Métodos: Estudo prospectivo observacional que incluiu consecutivamente todos os doentes referenciados aos cuidados paliativos com tumores sólidos metastizados e sem tratamento oncológico específico. Foi considerada a intensidade de dor da escala de Edmonton, de acordo com a graduação zero a 10, onde 0 = ausência de dor e 10 = máxima dor possível. Resultados: Entre outubro de 2012 e junho de 2015, foram incluídos 301 doentes, com idade mediana de 69 anos (37 - 94), 57% homens e 64,8% dos doentes com performance status 3/4. Aproximadamente 42% dos doentes apresentaram dor ≥ 4 e cerca de 74,4% estavam medicados com analgesia opióide. A intensidade de dor esteve associada ao performance status dos doentes, de acordo com a análise multivariável (OR: 1,7; IC 95%: 1,0 - 2,7; p = 0,045). A mediana do tempo de sobrevivência foi de 37 dias (IC 95%: 28 - 46), tendo os doentes com dor moderada ou intensa (intensidade de dor ≥ 4) uma mediana de sobrevivência de 29 dias (IC 95%: 21 - 37), comparada com os 49 dias (IC 95%: 35 - 63) para os doentes sem dor ou dor ligeira (p = 0,022). Discussão: O performance status, para além de ter estado associado a uma maior intensidade de dor, esteve associado a um menor tempo até à morte dos doentes com cancro avançado referenciados aos cuidados paliativos. Também o internamento, a presença de metastização intra-abdominal e a analgesia opióide estiveram associados de forma negativa ao tempo até à morte destes doentes. Conclusão: A dor oncológica continua a ser um problema clinicamente relevante nos doentes com cancro avançado.

Does facial expressivity count? How typically developing children respond initially to children with autism.

Research investigating expressivity in children with autism spectrum disorder has reported flat affect or bizarre facial expressivity within this population; however, the impact expressivity may have on first impression formation has received little research input. We examined how videos of children with autism spectrum disorder were rated for expressivity by adults blind to the condition. We further investigated the friendship ratings given by 44 typically developing children to the same videos. These ratings were compared to friendship ratings given to video clips of typically developing children. Results demonstrated that adult raters, blind to the diagnosis of the children in the videos, rated children with autism spectrum disorder as being less expressive than typically developing children. These autism spectrum disorder children were also rated lower than typically developing children on all aspects of our friendship measures by the 44 child raters. Results suggest that impression formation is less positive towards children with autism spectrum disorder than towards typically developing children even when exposure time is brief.

A cross-sectional survey of the activity of palliative care teams in Portugal.

Of the 21 Portuguese teams identified, 10 accepted to participate in the study. A total of 164 patients were included with a median of 15.5 per team (4-32). Of all the patients included, 60 (37%) were identified as inpatients in palliative care units; 59 (36%) by an intrahospital support team; 26 (16%) as outpatients; and 19 (12%) at home. The median age was 71 years (16-95). Fifty-one percent were females. The diagnosis was cancer in 151 (92%) patients. The most common cancer was colorectal in 22 (15%) patients, followed by gastric 17 (11%), head and neck 17 (11%), breast 15 (10%), and lung cancers 14 (9%). All patients were treated by doctors and nurses experienced in palliative care.
