Paulo Sérgio Lucas da Silva, Marcelo Cunio Machado Fonseca
PURPOSE: Although several studies assess unplanned extubation (UE) in children, few have addressed determinants of UE and factors associated with reintubation in a case-controlled manner. We aimed to identify the risk factors and outcomes associated with UE in a pediatric intensive care unit. METHODS: Cases of UE were randomly matched with control patients at a ratio of 1:4 for age, severity of illness, and admission diagnosis. For cases and controls, we also collected data associated with UE events, reintubation, and outcomes...

Temporal niche partitioning may result from interference competition if animals shift their activity patterns to avoid aggressive competitors. If doing so also shifts food sources, it is difficult to distinguish the effects of interference and consumptive competition in selecting for temporal niche shift. Bees compete for pollen and nectar from flowers through both interference and consumptive competition, and some species of bees have evolved nocturnality. Here, we use tropical forest canopy towers to observe bees (the night-flying sweat bees Megalopta genalis and M...

BACKGROUND: Fellowship trainees in Acute Care Surgery require experience in the management of complex and operative trauma cases. Trauma center staffing usually follows standard 12 or 24 hour shifts, with resident and fellow trainees following a similar schedule. Although trauma admissions can be generally unpredictable, we analyzed temporal trends of trauma patient arrival times to determine the best time frame to maximize trainee experience during each day. METHODS: We reviewed ten years (2007-2016) of trauma registry data for blunt and penetrating trauma activations...

Shift work has been suggested to be associated with breast cancer risk, and circadian disruption in shift workers is hypothesized as one of the mechanisms of increased cancer risk. There is, however, insufficient molecular evidence supporting this hypothesis. Using the quantitative methodology of pyrosequencing, epigenetic changes in 5-methyl cytosine (5mC) in five circadian genes CLOCK, BMAL1, CRY1, PER1 and PER2 in female nurses working night shift work (278 breast cancer cases, 280 controls) were analyzed...

Gabriele d'Ettorre
Objectives: The prevention of needlestick and sharp injuries (NSSIs) among registered nurses (RNs) employed in hospital wards represents an important issue. Accidental contact with blood, consequent to NSSIs, is the most frequent form of exposure to blood-borne pathogens that can be transmitted by accidental exposure. Aims: This study investigates the relationship occurring between consecutive workdays, night-shifts, cumulative hours, forward-rotating shift schedules (morning-afternoon-night), and occupational NSSIs frequency...

Systolic (S) and diastolic (D) blood pressures (BP) [SBP and DBP] are circadian rhythmic with period (τ) in healthy persons assumed to be maintained at 24.0h. We tested this assumption in a sample of 30 healthy career (mean >12 yrs) 30-to-46 yr-old male Caucasian French firefighters (FFs) categorized into three groups according to work schedule and duties: Group A - 12 FFs working 12h day, 12h night, and occasionally 24h shifts and whose primary duties are firefighting plus paramedical and road rescue services; Group B - 9 FFs working mostly 12h day and 12h night shifts and whose duties are answering incoming emergency calls and coordinating service vehicle dispatch from fire stations with Group A personnel; Group C - 9 day shift (09:00-17:00h) FFs charged with administrative tasks...

The expression levels or activities of biological defense factors can fluctuate daily following biological rhythms. We have focused on the relationship between injection timing and the degree of toxicity of cadmium (Cd) to promote the concept of "chronotoxicology," which introduces chronobiology to the field of toxicology. Our previous studies have clearly indicated that Cd may be subject to chronotoxicity. In this report, to confirm the character of the Cd-induced chronotoxicity, we performed multidirectional examinations...

Most organisms use internal biological clocks to match behavioural and physiological processes to specific phases of the day-night cycle. Central to this is the synchronisation of internal processes across multiple organ systems. Environmental desynchrony (e.g. shift work) profoundly impacts human health, increasing cardiovascular disease and diabetes risk, yet the underlying mechanisms remain unclear. Here, we characterise the impact of desynchrony between the internal clock and the external light-dark (LD) cycle on mammalian physiology...

Adolescents naturally go to bed and awaken late, but are forced to awaken early for school and work. This leads to "social jetlag", a state of circadian desynchrony (CD), in which internal biological rhythms are out of sync with behavioral rhythms. CD is associated with increased alcohol intake in adults, but has been less well-studied in adolescents. The goal of this study was to model adolescent alcohol intake during similar CD conditions in male C57BL/6J mice. Free access alcohol intake, water intake and wheel-running activity were measured during a normal 12HR photoperiod or during alternating photoperiod (Experiment 1: 12 h light for 4 days followed by 18 h light for 3 days, with dark (activity onset) delayed 9 h during the 18HR photoperiod; Experiment 2: 12 h light for 4 days followed by 6 h light for 3 days, with dark onset delayed 3 h during the 6HR photoperiod)...

BACKGROUND: The primary care out-of-hours (OOH) services in Norway are characterized by high contact rates by telephone. The telephone contacts are handled by local emergency medical communication centres (LEMCs), mainly staffed by registered nurses. When assessment by a medical doctor is not required, the nurse often handles the contact solely by nurse telephone counselling. Little is known about this group of contacts. Thus, the aim of this study was to investigate characteristics of encounters with the OOH services that are handled solely by nurse telephone counselling...

INTRODUCTION: Mechanical restraint and other forms of coercion may be used under certain circumstances at psych-iatric wards. The use of coercion receives considerable focus, yet little is known about its diurnal distribution. We examined the initiation of mechanical restraint, sedative drug administration, physical retention, door locking and personal shielding by time of day and week. METHODS: Group 3 protocols in the national Register of Coercion for patients aged ≥ 18 years in the years 2010-2012 were analysed...

PURPOSE OF REVIEW: The investigation of the relationship between the time of day that school begins and the effects it could have on students began in the mid-1990s. Since that time, many articles have been written either for the medical literature or the educational literature. This review is intended to bridge that gap by examining together the findings for both academic and health outcomes, exploring what we know and what is needed in further investigation. RECENT FINDINGS: Teens who are sleep deficient (defined as obtaining less than 8 h per night) because of early starting time for their school are much more likely to engage in risky behaviours, such as drug, cigarette and alcohol use, have significant feelings of depression, get lower grades and are at greater risk for car crashes...

Shift work sleep disorder is a common problem in industrialized countries because of the need for occupations and services to continue to function 24 hours/day. Approximately 20% of employed adults in the United States are engaged in shift work. Shift work sleep disorder is diagnosed if there is a report of insomnia or excessive sleepiness for at least 3 months associated with a recurring work schedule that overlaps the usual time for sleep. Shift work is associated with an increased occurrence of metabolic disorders, such as insulin resistance, diabetes, dyslipidemia, and metabolic syndrome, and it has been implicated in weight gain and cognitive impairment...
