Psychosocial Determinants of Mental Healthcare Use Among Mexican-origin Women from Farmworker Families in Southern California.

Little is known about the contribution of psychosocial factors related to mental healthcare use among Mexican-origin women from farmworker families. Therefore, this study assessed relationships between acculturative stress, depressive symptoms, mental healthcare service use, and preferences for seeking care. Linear and logistic regression models and chi-square tests were performed to analyze survey data from 78 Mexican-origin women from farmworker families. Women were recruited in collaboration with promotoras and completed measures of acculturative stress, depressive symptoms, and mental healthcare use and preferences. Overall, 29.5% of the sample reported clinically significant depressive symptomatology. Acculturative stress was positively associated with depressive symptoms (b = 0.43, 95%CI = 0.27,0.59) after controlling for years in the U.S., primary language, and demographic characteristics. In addition, acculturative stress was associated with lower odds of mental healthcare use (OR = 0.96) after controlling for years in the U.S. and depressive symptoms. However, this association was no longer statistically significant when controlling for health insurance status and access to transportation. Mexican-origin women with high levels of acculturative stress were significantly more likely to seek care from a psychiatrist/psychologist than their peers (54.3% vs. 45.7%); however, this preference was not indicative of their use of mental healthcare services. Results suggest that acculturative stress is a risk factor for depressive symptoms and might contribute to a delay in seeking mental healthcare services in Mexican-origin women from farmworker families. Thus, interventions for this group should address aspects of acculturative stress as a strategy to increase mental health services use.

Anatomic and histologic analysis of paca larynx (Cuniculus paca, Linnaeus 1766) / [Análise anatômica e histológica da laringe da paca (Cuniculus paca, Linnaeus 1766)]

Paca (Cuniculus paca) has encouraged research as an experimental model both in the human medicine and veterinary, as well as the economic exploitation of its meat cuts, which favored its zootechnical use. There are no anatomical, microscopic descriptions and measurements of the larynx in this rodent. Eight pacas were dissected from the wild animal's sector of the Faculty of Agricultural and Veterinary Sciences of the University of the State of São Paulo. The larynx was observed located in the ventral region of the neck, ventral to the esophagus, connecting the pharynx to the trachea, with cylindrical and irregular shape. Laryngeal cartilages (epiglottic, thyroid, cricoid and arytenoid) are interconnected and have different shapes. Thyroid showed greater length and width, compared to the others. Laryngeal cartilages were submitted to histological processing and stained with hematoxylin-eosin and Masson's trichrome. The epiglottic cartilage was stained with toluidine blue. Laryngeal cartilages thyroid, cricoid and the lower portion of the arytenoids are of hyaline origin and, in contrast, the epiglottis and the upper portion of the arytenoids are elastic. This latter cartilage demonstrated taste buds. The results will be able to auxiliate in veterinary care and as well as the conservation programs for this rodent.(AU)

A paca (Cuniculus paca) tem encorajado inúmeras pesquisas, tornando-a modelo experimental tanto em humanos como na veterinária, além da exploração econômica de seus cortes cárneos, que favoreceu diretamente sua importância zootécnica. Não há descrições anatômicas, microscópicas e mensurações da laringe desse roedor. Foram dissecadas oito laringes de pacas, provenientes do setor de Animais Silvestres da Faculdade de Ciências Agrárias e Veterinárias - Universidade Estadual Paulista. Observou-se que a laringe localiza-se na região ventral do pescoço, ventral ao esôfago, conectando a faringe à traqueia, possuindo formato cilíndrico e irregular. As cartilagens laríngeas (epiglote, tireóide, cricóide e aritenóidea) são interligadas e possuem formatos variados. A cartilagem tireóide demonstrou-se maior em comprimento e largura, comparativamente às demais. As cartilagens laríngeas foram submetidas a processamento histológico e coradas em hematoxilina-eosina e tricrômio de Masson. A cartilagem epiglote foi corada em azul de toluidina. As cartilagens laríngeas tireóide, cricóide e a porção inferior das aritenóides são de origem hialina; em contrapartida, a epiglote e a porção superior das aritenóides, de origem elástica. Esta última cartilagem demonstrou corpúsculos gustativos. Os resultados poderão auxiliar tanto nos atendimentos veterinários quanto nos programas de conservação desse roedor.(AU)

Mexican-origin male perspectives of diet-related behaviors associated with weight management.

BACKGROUND: Prevalence rates of obesity and related diseases are quickly reaching epidemic proportions among Hispanic males in the United States. Hispanic males suffer from the highest prevalence of obesity-related diseases when compared to all other racial/ethnic groups. Despite evidence showing that weight loss can significantly reduce the risk of obesity-related health implications, literature informing best practices to engage Hispanic males in weight management programs is scarce. PURPOSE: The purpose of the current study was to engage Spanish-speaking, Mexican-origin males with overweight or obesity to examine their perspectives of diet-related behaviors related to weight management. METHODS: Demographic and acculturation data were collected using questionnaires. Fourteen semistructured interviews were completed with an all-Spanish-speaking cohort of men (age: 45.0±9.8 years; BMI: 34.2±6.5 kg m-2) who were born outside of the United States. We conducted a thematic analysis using a hybrid deductive-inductive analysis strategy using a previously developed codebook that was updated during iterative analysis of interview transcripts. RESULTS: Participants reported that healthful eating habits were hindered, among other factors, by lack of knowledge, sociocultural norms and conceptualizations of masculinity. Viable diet-related intervention approaches also surfaced, including building consciousness, promotion of traditional knowledge and the integration of the family in interventions. CONCLUSION: Findings suggest that Spanish-speaking, Mexican-origin men have interest in actively engaging in behavior changes that improve their dietary habits and engage in weight management. Our findings yield valuable insights that can be used to formulate tailored intervention strategies to improve obesity prevention and treatment programs for this vulnerable subgroup.

Applicability of polyamide 12 intramedullary locked rods in the stabilization of induced humeral fracture in cockerels (white plymouth rock) - in vivo study / Aplicabilidade da haste intramedular bloqueada de poliamida 12 na estabilização de fratura umeral induzida em galos (Plymouth Rock Branca) - estudo in vivo

The aim of this study was to evaluate the use of polyamide 12 intramedullary rods in osteotomized humerus in cockerels (White Plymouth Rock) and analyze, by radiography and histopathology, bone consolidation and the formation of bone callus. Ten cockerels were subjected to transverse osteotomy of the right humeral diaphysis followed by the insertion of polyamide 12 locked rods, with two nails in each bone fragment. Radiographies obtained at the immediate pre and post-operative period, and every 7 days for 3 months revealed no perioperatory complications. Radiography revealed a radiopaque bone callus between the 4th and 5th week post-surgery. Histopathology detected an amphophylic material (polyamide 12 rod) in the intramedullary region and the proliferation of highly vascularized connective tissue between the rod and the cortical bone. This connective tissue was highly cellular with differentiation into osteoblasts. The collagen fibers varied from loose to dense and a differentiated bone matrix, containing osteocytes in gaps and the development of bone marrow, was also observed; indicating the formation of a bone callus without signs of implant rejection. The polyamide 12 intramedullary rod was effective in the stabilization of the fractures used in this experimental model, with no rejection reaction for at least 90 days.(AU)

O presente estudo teve como objetivo avaliar a implantação de hastes intramedulares de poliamida 12, em úmeros osteotomizados de galos (Plymouth Rock Branca), bem como avaliar a consolidação óssea, por meio da verificação da formação de calo ósseo, analisando exames radiográficos e histopatológicos. Os galos foram submetidos à osteotomia transversa da diáfise do úmero direito, sendo implantadas posteriormente as hastes de poliamida 12 bloqueada com dois parafusos em cada fragmento ósseo. Após o procedimento cirúrgico, foram realizadas radiografias nos momentos pré e pós-operatório imediato e, posteriormente, a cada sete dias, durante três meses, até a realização da eutanásia. Não houve complicações perioperatórias. Ao exame radiográfico, os animais apresentaram formação de calo ósseo radiopaco entre a quarta e quinta semanas de pós-operatório. Ao exame histopatológico, foi possível notar, em todos os animais, presença de material anfofílico (haste de poliamida 12) ocupando a região intramedular óssea, e entre a haste e as corticais ósseas, proliferação de tecido conjuntivo altamente vascularizado. Tal tecido apresentou-se altamente celular com diferenciação em osteoblastos. Notaram-se também fibras colágenas, variando de aspecto frouxo a denso, e observou-se formação de matriz óssea diferenciada com osteócitos em lacunas e formações de medula óssea, denotando formação de calo ósseo sem sinais de rejeição do implante. A haste intramedular de poliamida 12 foi eficaz para estabilização das fraturas utilizando-se esse modelo experimental, sem reação de rejeição pelo período de 90 dias.(AU)
