Substance use and adolescent mental health during the COVID-19 pandemic in Brazil: a longitudinal approach.

OBJECTIVE: To describe the changes in alcohol and drug use by Brazilian adolescents during the COVID-19 pandemic (April-August 2021), and to analyze the relationship between alcohol use changes and psychiatric symptomatology. METHODS: A secondary analysis with a longitudinal approach was performed with data from a cluster-randomized controlled trial, conducted in 73 public middle schools in three Brazilian cities, to evaluate the effectiveness of a drug use prevention program. The sample included 535 students (61% girls; Mage = 15.2 years). Data were collected pre-intervention (February-March 2019), after 9 months (November-December 2019), and after 26 months (April-August 2021), when the students were in their first year of high school. The authors analyzed drug use prevalence (alcohol, binge drinking, tobacco, inhalants, marijuana, cocaine, and crack) in a lifetime, past year, and past month periods, and the association between alcohol use change subsamples with psychiatric symptoms. Logistic regressions were adjusted by sex, age, socioeconomic status, city, and group (control and intervention). RESULTS: The present findings suggest that the COVID-19 pandemic led to a decrease in past-year substance use and in past-month substance use frequency, despite the gradually increased (but decelerating) prevalence of lifetime use. However, some adolescents initiated, maintained, or increased the frequency of their alcohol use. Mainly, they were more likely to present behavioral problems, as well as symptoms of inattentive hyperactivity, and peer and emotional problems. CONCLUSIONS: Despite the extensive decline in substance use during the pandemic period, these results suggest an association between previous mental health conditions and behavioral risk factors, leading to increased alcohol consumption and behavioral disorders manifestations.

Uncoupling of behavioral and metabolic 24-h rhythms in reindeer.

Reindeer in the Arctic seasonally suppress daily circadian patterns of behavior present in most animals.1 In humans and mice, even when all daily behavioral and environmental influences are artificially suppressed, robust endogenous rhythms of metabolism governed by the circadian clock persist and are essential to health.2,3 Disrupted rhythms foster metabolic disorders and weight gain.4 To understand circadian metabolic organization in reindeer, we performed behavioral measurements and untargeted metabolomics from blood plasma samples taken from Eurasian tundra reindeer (Rangifer tarandus tarandus) across 24 h at 2-h intervals in four seasons. Our study confirmed the absence of circadian rhythms of behavior under constant darkness in the Arctic winter and constant daylight in the Arctic summer, as reported by others.1 We detected and measured the intensity of 893 metabolic features in all plasma samples using untargeted ultra-high-performance liquid chromatography-mass spectrometry (UPLC-MS). A core group of metabolites (66/893 metabolic features) consistently displayed 24-h rhythmicity. Most metabolites displayed a robust 24-h rhythm in winter and spring but were arrhythmic in summer and fall. Half of all measured metabolites displayed ultradian sleep-wake dependence in summer. Irrespective of the arrhythmic behavior, metabolism is rhythmic (24 h) in seasons of low food availability, potentially favoring energy efficiency. In seasons of food abundance, 24-h rhythmicity in metabolism is drastically reduced, again irrespective of behavioral rhythms, potentially fostering weight gain.

Reindeer in the Arctic reduce sleep need during rumination.

Timing and quantity of sleep depend on a circadian (∼24-h) rhythm and a specific sleep requirement.1 Sleep curtailment results in a homeostatic rebound of more and deeper sleep, the latter reflected in increased electroencephalographic (EEG) slow-wave activity (SWA) during non-rapid eye movement (NREM) sleep.2 Circadian rhythms are synchronized by the light-dark cycle but persist under constant conditions.3,4,5 Strikingly, arctic reindeer behavior is arrhythmic during the solstices.6 Moreover, the Arctic's extreme seasonal environmental changes cause large variations in overall activity and food intake.7 We hypothesized that the maintenance of optimal functioning under these extremely fluctuating conditions would require adaptations not only in daily activity patterns but also in the homeostatic regulation of sleep. We studied sleep using non-invasive EEG in four Eurasian tundra reindeer (Rangifer tarandus tarandus) in Tromsø, Norway (69°N) during the fall equinox and both solstices. As expected, sleep-wake rhythms paralleled daily activity distribution, and sleep deprivation resulted in a homeostatic rebound in all seasons. Yet, these sleep rebounds were smaller in summer and fall than in winter. Surprisingly, SWA decreased not only during NREM sleep but also during rumination. Quantitative modeling revealed that sleep pressure decayed at similar rates during the two behavioral states. Finally, reindeer spent less time in NREM sleep the more they ruminated. These results suggest that they can sleep during rumination. The ability to reduce sleep need during rumination-undisturbed phases for both sleep recovery and digestion-might allow for near-constant feeding in the arctic summer.

Factors associated with attending "open bar" parties amongst early adolescents.

BACKGROUND: "Open bar" parties are events where a flat fee is paid for unlimited alcohol consumption. At these events, alcohol intoxication is frequent amongst attendees. This study explored the prevalence of "open bar" attendance amongst Brazilian youth and the factors associated with this practice. METHODS: Data was collected at the baseline of randomized controlled trial amongst 5,213 8th grade students in three Brazilian cities. Weighted logistic regression was performed. RESULTS: Mean age was of 13.23 years (SE 0.01) and 17.1% of the students have reported attending "open bar" events in the past year. Attendees were wealthier, had higher odds to engage in binge drinking, to use marijuana, to be exposed to alcohol advertising, and to report more alcohol problems and clinical psychiatric symptoms when compared with non-attendees. CONCLUSIONS: The ban on selling alcohol to minors has not been properly enforced. Legislation to restrict alcohol promotions and advertising in Brazil needs to be implemented and effectively monitored.

Time series analysis of the suicide attempts assisted by firefighters from 2017 to 2021 in São Paulo, Brazil.

OBJECTIVE: This study aimed to analyze the time trends of suicide attempts assisted by the Fire Department of the Military Police of the State of São Paulo (Corpo de Bombeiros da Polícia Militar do Estado de São Paulo - CBPMESP) from 2017 to 2021, between sexes. METHODS: This is an ecological study of 11,435 suicide attempts assisted by CBPMESP calls from January 2017 to December 2021. Three seasonal auto-regressive integrated moving average with exogenous (SARIMAX) models were adjusted considering total population, only men, and only women. RESULTS: The total occurrences of suicide attempts were stationary in the prepandemic period but had an increased growth pattern after the pandemic began. This trend was higher among men, due to (1) lower assistance of suicide attempts during early pandemic than in the prepandemic period and (2) significant increased assistance after the beginning of vaccination against COVID-19, followed by a decrease, but with a tendency to increase, in the long-term pandemic. CONCLUSION: Our results indicate a growth in the long-term suicide attempts during COVID-19. The beginning of vaccination was not considered significant in the reduction of CBPMESP attendances. These results corroborate the need for a multisectoral national suicide prevention strategy to mitigate the effects of the pandemic on mental health in the State of São Paulo.

Suicide Attempts Assisted By Firefighters According to Traumatic Brain Injury.

Studies worldwide have reported increasing trends in suicides and attempts during the pandemic. The literature shows that improving surveillance and monitoring of suicide and attempts requires broad multisectoral prevention strategies. In Brazil, the São Paulo State Fire Department (CBPMESP) makes up the emergency response team for suicide and suicide attempted calls and public emergencies. Given this context, this paper sought to describe the characteristics of suicide attempts assisted by the CBPMESP according to traumatic brain injury (TBI), between 2018 and 2020, measured by the Glasgow Coma Scale (GCS). For this purpose, a descriptive study of 6,582 suicide attempts attended by CBPMESP was carried out. The factors associated with trauma brain injury according to the Glasgow Coma Scale (dependent variable) were analyzed by a multinomial regression model. Results show a significant increase of 8.0% (p = 0.039) in the number of calls responded by CBPMESP between 2018 and 2020. Men presented a higher prevalence of more violent methods for suicide attempts, namely firearms and hanging, followed by severe TBI; in women, severe TBI occurred mostly by hanging. Despite the increase in fatal suicide attempts during the pandemic, time to attend to victim acted as a protective factor for preventing severe TBI in men and women.

Primary health care performance according to clusters of convergent municipalities in the state of São Paulo.

OBJECTIVE: To describe the performance of Primary Health Care, according to conglomerates of São Paulo cities that present homogeneous indicators. METHODS: This is a descriptive study, based on secondary data extracted from official sources of the Unified Health System, for the year 2018. An analysis matrix was created, with the proposition of performance (access, effectiveness and adequacy) and context indicators (population, health determinants and financing) selected and organized in dimensions and sub-dimensions. Cluster Analysis was used to identify the groups of homogeneous municipalities. RESULTS: 645 municipalities were divided in 6 conglomerates. Clusters 2 and 3 were formed predominantly by small municipalities with greater access to health; cluster 3 has less social vulnerability and greater investment in health. Clusters 1, 4 and 5 were formed by the largest municipalities with less access to health; cluster 4 presents greater social vulnerability, less coverage of private health plans and a greater percentage of health resources; cluster 5 was characterized by greater Gross Domestic Product per capita and greater coverage of private health plans. Cluster 6, formed by the city of São Paulo, was a particular case. Cluster 2 drew attention, as it was shown to have increased coverage, but signaled lower efficacy and adequacy levels. Cluster 3 had the best performance among all clusters. CONCLUSION: These findings can support regional and municipal management, given the complexity of the territory of São Paulo, pointing to scenarios that demand broader public management initiatives.

Conclusiones: se encontró que no hay diferencia significativa entre los porcentajes del grupo sanguíneo A de los grupos comparados.

ABSTRACT Background: Gastric cancer has high incidence and mortality in Uruguay. Blood group A has been considered a risk factor for gastric cancer and has high prevalence in this disease. Objective: The aim of this study is to compare the percentage of blood group A in patients with gastric cancer and in blood donors in Uruguay. Material and methods: We conducted an observational and retrospective study. We used the sample size calculation for comparing proportions with a confidence of 95% and 80% power. The number calculated was 149 for each group. We included all the patients from Hospital Maciel and Cooperativa Médica de Florida who met the admission criteria and a population of blood donors from both institutions. The chi-square test was used and a p value < 0.05 was considered statistically significant. Results: A total of 153 patients and blood donors were included in each group. Blood group A was less common in gastric cancer patients than in blood donors (35.9% vs. 36.6%). The difference was not statistically significant between the groups studied. Conclusions: We did not find any significant difference in the percentage of blood group A in the groups compared.

National Institute of Mental Health Life Chart Method - Self/Prospective (NIMH-LCM-S/P™): translation and adaptation to Brazilian Portuguese.

OBJECTIVE: The objective of this study was to translate and adapt the National Institute of Mental Health Life Chart Method - Self/Prospective (NIMH-LCM-S/P™) instrument for self-monitoring of mood into Brazilian Portuguese and provide evidence of content validity. Additionally, a user guide was prepared for the instrument and evaluated by mental health professionals. METHODS: The study was divided into two stages - Stage 1: Translation and cross-cultural adaptation and Stage 2: Determination of content validity index (CVI) scores. The translation and cross-cultural adaptation process involved 37 participants between translators, experts, target population, and evaluators. RESULTS: The CVI was evaluated by 15 mental health professionals. 11 (78.57%) of the items evaluated attained the maximum CVI score of 1.00, which constitutes the highest level of content validity, and no changes were suggested by participants. Only one of the items evaluated had a CVI score lower than 0.80. CONCLUSION: The final translated and adapted version of the NIMH-LCM-S/P™ and its user guide were evaluated by the target population and the mental health professionals. Both groups displayed satisfactory comprehension levels, suggesting there is potential for using this instrument in clinical practice to assess therapeutic interventions in Brazilian settings.

Introdução: Entre os cânceres de mama, aproximadamente 75% das mulheres são receptores hormonais positivos, sendo estas mais propensas a responderem à hormonioterapia com anastrozol e tamoxifeno. Apesar de eficazes, apresentam taxas significativas de não adesão. Objetivo: Avaliar a adesão à terapia hormonal adjuvante com tamoxifeno e anastrozol em pacientes atendidos nos Ambulatórios da Mastologia e de Quimioterapia do Hospital São Paulo entre os anos de 2019 e 2020. Método: Estudo transversal com 102 mulheres, realizado entre os meses de setembro de 2019 e março de 2020. A adesão à terapia hormonal adjuvante foi avaliada utilizando-se as escalas Morisky Medication Adherence Scale (MMAS-4) e Adherence to Refills and Medications Scale of 12 items (ARMS-12). Resultados: A média de idade foi de 61,5 anos (59,3-63,6). Entre as pacientes, 27,7% faziam uso de tamoxifeno e 72,3% de anastrozol. Relataram desconforto em relação ao uso do medicamento 84,4%, sendo as ondas de calor (42,2%) e as dores articulares (55,9%) os mais frequentes. A escala de ARMS>12 foi pontuada por 79,2%; cerca de 90% das mulheres pontuaram a MMAS-4 até dois pontos, porém não houve diferença significativa entre os tipos de hormônios utilizados para escalas de adesão (p=0,815 e p=0,489). Conclusão: A adesão à hormonioterapia observada foi relativamente baixa, independentemente da endocrinoterapia, podendo essas pacientes estarem em risco de inadequação quanto à resposta clínica

Introduction: Among breast cancers, approximately 75% of women are hormone receptors-positive, and these are more likely to respond to hormone therapy with anastrozole and tamoxifen. Although effective, they have significant rates of non-adherence. Objective: To evaluate adherence to adjuvant hormone therapy with tamoxifen and anastrozole in patients consulted at the Mastology and Chemotherapy Outpatient Clinic of Hospital São Paulo between 2019 and 2020. Method: Cross-sectional study carried out with 102 women between September 2019 and March 2020. Adherence to hormone therapy was evaluated using the Morisky Medication Adherence Scale (MMAS-4) and Adherence to Refills and Medications Scale of 12 items (ARMS-12). Results: The mean age was 61.5 years (59.3-63.6). Among the patients, 27.7% used tamoxifen and 72.3%, anastrozole. 84.4% of them reported discomfort in using the medication, the most frequent were hot flashes (42.2%) and joint pain (55.9%). 79.2% scored the ARMS>12 scale, about 90% of the women scored MMAS-4 up to 2 points, but there was no significant difference between the types of hormones used for adhesion scales (p=0.815 to p=0.489). Conclusion: Adherence to hormone therapy was relatively low, regardless of the hormone used, and these patients may be at risk of inadequate clinical response

RESUMO Objetivo: Analisar as tendências temporais das tentativas de suicídio atendidas pelo Corpo de Bombeiros da Polícia Militar do Estado de São Paulo (CBPMESP) de 2017 a 2021, entre os sexos. Métodos: Estudo ecológico de 11.435 tentativas de suicídio atendidas pelo CBPMESP de janeiro de 2017 a dezembro de 2021. Três modelos autorregressivos integrados e de médias móveis sazonais multiplicativos com variáveis explicativas (SARIMAX) foram ajustados considerando-se a população total, apenas homens e apenas mulheres. Resultados: As ocorrências totais de tentativas de suicídio foram estacionárias no período pré-pandemia, mas tiveram um padrão de crescimento aumentado após o início da pandemia. Essa tendência foi maior entre os homens, seguindo o seguinte padrão: (a) menor ocorrência de tentativas de suicídio entre homens no início da pandemia quando comparado ao período pré-pandemia; e (b) aumento significativo das ocorrências após o início da vacinação contra COVID-19 no Estado de São Paulo, seguido de queda, mas com tendência de aumento na pandemia de longo prazo. Conclusão: Nossos resultados indicam aumento nas tentativas de suicídio em longo prazo durante a COVID-19. O início da vacinação não foi considerado significativo na diminuição dos atendimentos do CBPMESP. Esses resultados corroboram a necessidade de uma estratégia nacional multissetorial de prevenção ao suicídio para mitigar os efeitos da pandemia na saúde mental no Estado de São Paulo.

Percepção de farmacêuticos na implantação do Cuidado Farmacêutico na Atenção Básica / Pharmacists' perceptions on the implementation of Pharmaceutical Care in Primary Care

Resumo O artigo descreve a percepção de 10 farmacêuticos da Atenção Básica (AB) de uma região do município de São Paulo que participaram do processo de implantação do Cuidado Farmacêutico. A partir de uma pesquisa qualitativa com grupos focais e abordagem descritiva, os conteúdos foram analisados utilizando-se a Análise de Conteúdo. Das 52 unidades de registro organizadas em 10 categorias, resultaram três sínteses sobre o processo de implantação do CF. Nesse contexto, foi possível descrever o papel do farmacêutico na AB após a implantação dos serviços clínicos, de modo a identificar suas percepções, dificuldades e avanços. Os resultados demonstraram aspectos positivos, além da necessidade de uma mudança gradual no perfil e nas competências dos farmacêuticos para o desenvolvimento de serviços clínicos, ultrapassando os limites da categoria e dependendo do trabalho em equipe realizado na AB. Logo, os resultados promovem os diferentes papéis dos atores envolvidos nesta prática (usuários, equipe de saúde, gestores e farmacêuticos) e valorizam novas formas de cuidado no SUS.

Abstract The article describes the perception of 10 pharmacists from the Primary Health Care (PHC) of a region in the municipality of São Paulo that participated in the process of implementing the Pharmaceutical Care (PC). Based on qualitative research with focus groups and descriptive approach, contents were reviewed using the Content Analysis. The 52 registration units organized in 10 categories resulted in three summaries about the PC implementation process. In this context, we could describe the role of pharmacists in PHC after the implementation of clinical services, in order to identify their perceptions, difficulties and advances. Results unveiled positive aspects, besides the need for gradual change in the profile and competences of pharmacists to develop clinical services, extrapolating the category boundaries, and depending on the teamwork performed at PHC. Therefore, results promote the different roles of the players involved in this practice (users, health team, managers, and pharmacists), and value new forms of care in the Brazilian Health System (SUS).

RESUMO: Objetivo: Descrever o desempenho da atenção primária à saúde, segundo clusters de municípios paulistas que apresentaram indicadores homogêneos. Métodos: Trata-se de um estudo descritivo, com base em dados secundários extraídos de fontes oficiais do Sistema Único de Saúde, referentes ao ano de 2018. Foi elaborada uma matriz de análise, com a proposição de indicadores de desempenho (acesso, efetividade e adequação) e contexto (população, determinantes de saúde e financiamento), selecionados e organizados em dimensões e subdimensões. Para identificar os grupos de municípios homogêneos, foi utilizada a análise de cluster Resultados: Dos 645 municípios, constituíram-se seis clusters. Os clusters 2 e 3 foram formados, predominantemente, por municípios pequenos e com maior acesso; entre eles, o cluster 3 apresentou menor vulnerabilidade social e maior investimento em saúde. Os clusters 1, 4 e 5, em contrapartida, foram formados por municípios maiores e com menor acesso; entre eles, o cluster 4 apresentou maior vulnerabilidade social, menor cobertura de planos privados de saúde e maior percentual de recursos utilizados em saúde; e o cluster 5, maior produto interno bruto per capita e maior cobertura de planos privados de saúde. O cluster 6, formado pelo município de São Paulo, demonstrou ser um caso particular. Ainda, o cluster 2 chamou atenção. Apresentando maior cobertura, sinalizou menor efetividade e adequação. Entre todos os clusters, o cluster 3 alcançou o melhor desempenho. Conclusão: Os resultados podem subsidiar a gestão regional e municipal, diante da complexidade do território paulista, apontando para cenários que demandam maiores inciativas de gestão pública.

Relationship between cocaine and cocaethylene blood concentration with the severity of clinical manifestations.

BACKGROUND: Poisonings resulting from the abuse of drugs currently represent a serious problem for public health. Among the main agents involved, cocaine stands out. It became one of the most abused drugs around the world, and one of the main reasons for visits to the emergency department due to the use of illicit substances. The use of cocaine is primarily in combination with alcoholic beverages. There are few studies that correlate cocaine blood concentration and the severity of clinical manifestations in patients evaluated at Emergency Department. The aim of the present study was to verify the possible relationship between the blood concentration of cocaine and cocaethylene (product of the interaction of cocaine with ethanol) with the severity of the clinical manifestations presented by patients with cocaine intoxication. METHODS: Blood levels were measured by high-performance liquid chromatography (HPLC) and the severity of clinical manifestations was assessed using the Stimulant Intoxication Score (SIS). To establish this relationship, Pearson's chi-square statistical test (x2) was used for categorical variables and Student's t for continuous variables, with statistical significance of 5% (p < 0.05). RESULTS: Of the 81 patients included in the study, 77.8% were men with a mean age of 32.5 years ± 8.5 and mean of SIS 3.4 ± 2.5. Considering the toxicological analysis results, 24.7% of the blood samples were positive. The mean of cocaine and cocaethylene concentrations were 0.34 µg/mL ± 0.45 and 0.38 µg/mL ± 0.34, respectively. The blood concentration of cocaine and cocaethylene has not been shown to be useful information for the treatment and prognosis of patients, but blood levels of these substances at the time of treatment, regardless of their concentration, may be an indicator of severity, showing that any concentrations of these substances should be considered as potentially toxic. CONCLUSION: The application of the SIS score proved to be an important alternative capable of predicting the severity of the patients due to cocaine intoxication in a fast and simplified way.

The relationship between level of education and moral judgment toward who abuse drugs.

The aim of the present study is to verify the differences of the moral judgment toward the people who abuse drugs according to the schooling of the participants. This is the Brazilian part of a multicentric study. N=180 individuals in a community in Brasília, DF, Brazil; following consent, descriptive data were collected by anonymous interviewer-administered questionnaire that included socio-demographic, educational level and the history of drug use. Participants were predominantly females, middle-aged, married, employed, religious, with high school education; higher schooling considered alcohol abusers, marijuana, cocaine and crack are important as anyone else; the majority with lower education level knew someone who used drugs, but no association was found regarding drug use and schooling; in the unadjusted logistic regression model, positive associations were found between higher schooling and 'who use drugs are as important as anyone else' for all drugs studied; after adjusted, the association remained only for marijuana (all p<0.05). The negative attitude surrounding drugs issue can be an important obstacle. The results suggest that education can help to reduce the stigma associated; public policies would be important to minimizing social harm caused by stigmatized visions of drug users.

Analysis of gaps in alcohol policies in Brazil using the Pan American Health Organization's Alcohol Policy Scoring.

BACKGROUND: National alcohol policies need to be systematized and evaluated to identify the gaps that should be filled by future laws. This study aims to search for and classify Brazilian public alcohol policies at the federal and state levels, based on the ten Alcohol Policy Scoring (APS) domains used by the Pan American Health Organization (PAHO), to identify any gaps METHODS: Documental research was carried out in two phases: document identification and content analysis. The search included laws, decrees, and ordinances for alcohol referred to in this text as regulatory documents (RD), enacted until December 31, 2019, in Brazil and its 26 states and the Federal District. The APS was used to classify and score the RD, which consists of ten policy domains (including pricing, availability, marketing, and health services), weighted according to the level of scientific evidence of each strategy RESULTS: We identified and categorized 435 valid RD (21 national laws and 414 state laws). Overall, Brazilian alcohol policies account for 51.6% (255/494) of the APS score. In the pricing policy domain, the second most robust indicator of the APS, the policy gap reached 87% in 25 states, demonstrating a weakness. Only the federal laws against drink-driving include all the recommended dimensions. There are important legislative contradictions in the definition of an alcoholic beverage and in the content of the policies to control marketing CONCLUSION: At the national level, the federal government adopted alcohol policies in several of the PAHO policy domains but enacted RD with little practical effect. At the subnational level, despite the autonomy to complement federal laws, the states have not yet addressed the most important gaps.

Have countries offered the best data to the Pan American Health Organization? Evidence of potential inconsistencies found in a study on alcohol policies in Brazil.

OBJECTIVE: The objective of this study was to verify the agreement between the alcohol policies score estimated from documental analysis of Brazilian federal regulatory documents (RD), with primary data collection, and the results previously presented by the Pan American Health Organization (PAHO) in its Alcohol Policy Scoring (APS) report. STUDY DESIGN: Document identification and content analysis. METHODS: Documental research was carried out in two phases: a document identification and content analysis. In the first phase, we carried out the search, identification, and systematization of laws, decrees, and federal ordinances in Brazil, with primary data collection. The second phase consisted of three steps: 1) an RD content analysis and classification into the 10 PAHO/World Health Organization (WHO) policy domains; 2) a score estimation of alcohol policies, based on the APS instrument attached to their report; and 3) comparison of the results for Brazil presented at the APS report and the one estimated by the researchers. RESULTS: The study showed divergences between the results for APS published by PAHO about Brazil and the one achieved with primary data collection. 1146 federal promulgated RD were identified, of which 21 were eligible for content analysis. Only the domains "Community and workplace action" (Domain 3) and "Reducing the public health impact of illicit and informally produced alcohol" (Domain 9) had convergent scores. On the other domains, usually the APS score estimated by PAHO differs from the one estimated with the primary data collection. CONCLUSIONS: We conclude that Brazil is not providing the best data for PAHO/WHO estimate its APS report, leading to the dissemination of imprecise results worldwide.

Evidence for circadian-based photoperiodic timekeeping in Svalbard ptarmigan, the northernmost resident bird.

The high Arctic archipelago of Svalbard (74°-81° north) experiences extended periods of uninterrupted daylight in summer and uninterrupted night in winter, apparently relaxing the major driver for the evolution of circadian rhythmicity. Svalbard ptarmigan (Lagopus muta hyperborea) is the only year-round resident terrestrial bird species endemic to the high Arctic and is remarkably adapted to the extreme annual variation in environmental conditions.1 Here, we demonstrate that, although circadian control of behavior disappears rapidly upon transfer to constant light conditions, consistent with the loss of daily activity patterns observed during the polar summer and polar night, Svalbard ptarmigans nonetheless employ a circadian-based mechanism for photoperiodic timekeeping. First, we show the persistence of rhythmic clock gene expression under constant light within the mediobasal hypothalamus and pars tuberalis, the key tissues in the seasonal neuroendocrine cascade. We then employ a "sliding skeleton photoperiod" protocol, revealing that the driving force behind seasonal biology of the Svalbard ptarmigan is rhythmic sensitivity to light, a feature that depends on a functioning circadian rhythm. Hence, the unusual selective pressures of life in the high Arctic have favored decoupling of the circadian clock from organization of daily activity patterns, while preserving its importance for seasonal synchronization.

Body Temperature and Activity Rhythms Under Different Photoperiods in High Arctic Svalbard ptarmigan (Lagopus muta hyperborea).

Organisms use circadian rhythms to anticipate and exploit daily environmental oscillations. While circadian rhythms are of clear importance for inhabitants of tropic and temperate latitudes, its role for permanent residents of the polar regions is less well understood. The high Arctic Svalbard ptarmigan shows behavioral rhythmicity in presence of light-dark cycles but is arrhythmic during the polar day and polar night. This has been suggested to be an adaptation to the unique light environment of the Arctic. In this study, we examined regulatory aspects of the circadian control system in the Svalbard ptarmigan by recording core body temperature (T b) alongside locomotor activity in captive birds under different photoperiods. We show that T b and activity are rhythmic with a 24-h period under short (SP; L:D 6:18) and long photoperiod (LP; L:D 16:8). Under constant light and constant darkness, rhythmicity in T b attenuates and activity shows signs of ultradian rhythmicity. Birds under SP also showed a rise in T b preceding the light-on signal and any rise in activity, which proves that the light-on signal can be anticipated, most likely by a circadian system.
