The impact of cultural stress on family functioning among Puerto Rican displaced families and the effect on mental health.

Hurricane María caused significant devastation on the island of Puerto Rico, impacting thousands of lives. Puerto Rican crisis migrant families faced stress related to displacement and relocation (cultural stress), often exhibited mental health symptoms, and experienced distress at the family level. Although cultural stress has been examined as an individual experience, little work has focused on the experience as a family. To address this gap, we conducted a mixed-methods study designed to examine the predictive effects of cultural stress on family conflict and its mental health implications among Puerto Rican Hurricane María parent and child dyads living on the U.S. mainland. In the quantitative phase of the study, 110 parent-child dyads completed an online survey assessing cultural stress, family dynamics, and mental health. As part of our primary analysis, we estimated a structural equation path model. Findings from the quantitative phase showed a significant positive relationship between family cultural stress and family conflict, as well as individual parent and child mental health symptoms. In the qualitative phase of the study, 35 parent-child dyads participated in individual interviews. Findings from the interviews revealed variations in difficulties related to language, discrimination, and financial burdens, with some participants adapting more quickly and experiencing fewer stressors. Findings also highlight the impact on mental health for both parents and youth, emphasizing the family-level nature of cultural stress, while noting a potential discrepancy between qualitative and quantitative findings in the discussion of family conflict.

Technology-based communication among Hurricane Maria survivors in the United States: a trans-territorial lens.

PURPOSE: Rooted in a trans-territorial framework, the present study was designed to provide new evidence regarding the patterns of communication among Hurricane Maria survivors who migrated to the U.S. in the aftermath of the storm. METHODS: A total of 319 Hurricane Maria survivor adults ages 18 and older were recruited into the Adelante Boricua study between August 2020 and October 2021. Most participants had relocated to the U.S. between 2017 and 2018. We used latent profile analysis and multinomial regression to examine the relationship of technology-based communication with depressive symptoms, well-being, cultural connection, and migration stress. RESULTS: We identified a five-class solution, consisting of (1) moderate communication (32%), (2) disengaged (24%), (3) no social media (18%), (4) daily with family in Puerto Rico (6%), and (5) daily trans-territorial (13%) typologies. Participants in the disengaged class were more likely to report elevated depressive symptoms and limited English proficiency, lower prosocial behaviors, lower levels of religiosity, lower attendance at religious services in the U.S., and less engagement in social activities, compared to participants in the Moderate Communication class. CONCLUSION: Roughly one in four individuals in our sample reported very limited technology-based communication with friends/family in their sending and new-receiving communities. As technology and smartphones continue to become integrated into 21st-century life, it is vital that researchers explore how the tremendous potential for connectedness relates to trans-territorial crisis migrants' well-being and adaptation.

Autobiographical amnesia and accelerated forgetting in transient epileptic amnesia.

BACKGROUND: Recurrent brief isolated episodes of amnesia associated with epileptiform discharges on EEG recordings have been interpreted as a distinct entity termed transient epileptic amnesia (TEA). Patients with TEA often complain of autobiographical amnesia for recent and remote events, but show normal anterograde memory. OBJECTIVE: To investigate (a) accelerated long term forgetting and (b) autobiographical memory in a group of patients with TEA. METHODS: Seven patients with TEA and seven age matched controls were evaluated on a range of anterograde memory tasks in two sessions separated by 6 weeks and by the Galton-Crovitz test of cued autobiographical memory. RESULTS: Patients with TEA showed abnormal long term forgetting of verbal material, with virtually no recall after 6 weeks. In addition, there was impaired recall of autobiographical memories from the time periods 1985-89 and 1990-94 but not from 1995-1999. CONCLUSIONS: TEA is associated with accelerated loss of new information and impaired remote autobiographical memory. There are a number of possible explanations including ongoing subclinical ictal activity, medial temporal lobe damage as a result of seizure, or subtle ischaemic pathology. Future analyses should seek to clarify the relationship between aetiology, seizure frequency, and degree of memory impairment.

Reproducibility of sterilized rubber impressions

Moldes, dentaduras e outros dispositivos odontológicos podem estar contaminados com a microflora oral ou outros microorganismos de patogenicidade variada do sangue ou saliva de pacientes. O controle da transmissão de infecção por meio de moldes tem sido tentado de diversas maneiras e, uma vez que a desinfecção é menos eficaz e apresenta muitos obstáculos para moldagens, vários métodos de esterilização têm sido propostos. Este estudo avaliou a reprodutibilidade de moldes de borracha após a esterilização por diferentes métodos. A estabilidade dimensional e molhabilidade de dois materiais de moldagem (polisiloxano de vinil e poliéter) foram avaliadas após esterilização por três métodos bastante conhecidos (imersão em glutaraldeído 2% por 10 h, autoclavagem e radiação por microondas). Moldes não-esterilizados foram usados como controle. O efeito do material da moldeira na precisão da moldagem e o efeito de surfatante tópico na molhabilidade também foram avaliados. ANOVA com método Dunnett foram usados para análise estatística. Todos os métodos de esterilização reduziram a reprodutibilidade das moldagens, porém nem sempre esta redução foi significante. A esterilização por microondas teve pequeno efeito na estabilidade e molhabilidade. Os maiores efeitos dos outros métodos puderam ser eliminados utilizando-se moldeiras de cerâmica e borrifando as superfícies dos moldes com surfatante antes de vazar o gesso. Houve uma exceção: o glutaraldeído diminuiu a estabilidade dimensional mesmo com o uso de moldeiras de cerâmica e surfatante. Concluiu-se que a esterilização dos moldes de borracha obtidos com moldeiras de acrílico esteve geralmente associada a certo grau de alteração dimensional. Energia de microondas parece ser uma técnica eficaz para esterilizar moldagens de borracha. A aplicação tópica de surfatantes ajudou a restaurar a molhabilidade de modelos esterilizados.

Reproducibility of sterilized rubber impressions.

Impressions, dentures and other dental appliances may be contaminated with oral micro-flora or other organisms of varying pathogenicity from patient's saliva and blood. Several approaches have been tried to control the transmission of infectious organisms via dental impressions and because disinfection is less effective and has several drawbacks for impression characterization, several sterilization methods have been suggested. This study evaluated the reproducibility of rubber impressions after sterilization by different methods. Dimensional accuracy and wettability of two rubber impression materials (vinyl polysiloxane and polyether) were evaluated after sterilization by each of three well-known methods (immersion in 2% glutaraldehyde for 10 h, autoclaving and microwave radiation). Non-sterilized impressions served as control. The effect of the tray material on impression accuracy and the effect of topical surfactant on the wettability were also evaluated. One-way ANOVA with Dunnett's method was used for statistical analysis. All sterilizing methods reduced the reproducibility of rubber impressions, although not always significantly. Microwave sterilization had a small effect on both accuracy and wettability. The greater effects of the other methods could usually be overcome by using ceramic trays and by spraying impression surfaces with surfactant before pouring the gypsum mix. There was one exception: glutaraldehyde still degraded dimensional accuracy even with ceramic trays and surfactant. We conclude that a) sterilization of rubber impressions made on acrylic trays was usually associated with a degree of dimensional change; b) microwave energy seems to be a suitable technique for sterilizing rubber impressions; c) topical surfactant application helped restore wettability of sterilized impressions.

Periodontal disease among indigenous people in the Amazon rain forest.

BACKGROUND: People are not all equally susceptible to periodontitis. To understand the epidemiology and natural history of this disease, it is important to study populations with varying genetic backgrounds and environmental exposures. AIM: Characterize the periodontal condition of a sample of indigenous adults in a remote region of the Amazon rain forest and determine the association of periodontal disease with various demographic, behavioral and environmental factors. METHODS: A cross-sectional evaluation of 244 subjects aged 20-70 years was conducted. Pocket depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), plaque and calculus were assessed for the Ramfjord index teeth. RESULTS: These people had high levels of plaque, calculus and BOP. The mean PD was rather shallow (2.45 mm in 20-29 year-olds to 2.73 mm in 50+ year-olds) and did not increase significantly with age. Mean CAL (0.57 mm in 20-29 year-olds and 2.26 mm in 50+ year-olds) and mean location of the free gingival margin in relation to the cemento-enamel junction changed significantly with age (p<0.0001). Multivariate analysis revealed that increasing age, bleeding on probing and calculus scores were positively associated with mean CAL (p<0.01). Sex, ethnicity, level of modern acculturation, use of coca or tobacco paste, frequency of dental visits and plaque were not associated with mean CAL. CONCLUSIONS: Periodontal disease in these people was mainly associated with gingival recession rather than deep pockets. Most people had clinical attachment loss but despite poor oral hygiene and extensive gingival inflammation, they did not have very severe periodontal destruction.

Effects of cranial radiation on hearing in children with acute lymphocytic leukemia.

We serially assessed the hearing sensitivity of 61 children with acute lymphocytic leukemia who were admitted to our Total Therapy IX study between December, 1975, and July, 1977. Their treatment included combined chemotherapy, 2,400 rads of cranial radiation, and intrathecal methotrexate. Subjects initially received an otologic examination and middle ear function testing. Audiometric testing was not done until ears were free of outer or middle ear pathology. If the child had no outer or middle ear disease, audiometric thresholds were obtained for the test frequencies: 500, 1,000, 2,000, 4,000, 6,000, and 8,000 Hz. Pure-tone thresholds were obtained before irradiation (61 patients) and at 6, 12, and 36 months thereafter (49, 46, and 22 patients, respectively). The median age at time of baseline testing was 10 years, 2 months. A paired sample test based on group data was used to test whether there were any significant changes from the threshold values at 6, 12, and 36 months after irradiation. Thresholds were not significantly affected for any test frequency at any test time. Assessments of individual audiograms indicated that none of the children had any significant reductions in hearing levels at the end of the third year after cranial irradiation.
