The study aimed to quantify the impact of lockdown during the COVID-19 pandemic on new case referrals to the Oral and Maxillofacial Surgery (OMS) service. The researchers retrospectively reviewed all new referrals received during a government-imposed 47-day lockdown period and a similar period pre-lockdown as a control group. The main outcome was the differences in the number of new case referrals between the two periods. The contributing clinical and demographic factors were also explored. Appropriate bivariate statistics were computed and the level of significance was set at 0.05 for all tests. A total of 309 referrals were received during the study period. There was a reduction of new referrals due to the lockdown from five to two cases per day. There was a statistically significant reduction of cases referred from outpatient and emergency departments. There was also a statistically significant difference with regard to home address distance to the centre. Medically compromised and orofacial infection referrals were not affected by lockdown. The lockdown imposed due to the pandemic has significantly impacted the pattern of new OMS referrals. Referrals for orofacial infections, the medically compromised and inpatients were minimally affected by lockdown.

Sleep-related deaths are a leading cause of infant mortality in Florida. The American Academy of Pediatrics recommends placing infants to sleep on their back, alone, and without soft bedding. Compliance with these guidelines varies among parents. This evaluation examined the rates of safe infant sleep practices and associated factors among 1985 participants enrolled in Florida Maternal, Infant, and Early Childhood Home Visiting (FL MIECHV) programs during 2017–2019. Participant- and program-level variables were examined in relation to three sleep practices: infant position, bedding, and bed-sharing at 2–3 months to determine which factors were associated with high rates of safe sleep outcomes. Analyses included univariate descriptive statistics, bivariate statistics, and multivariable logistic regression. Most caregivers (70%) reported always placing their babies to sleep on their back, alone, and without soft bedding. Factors such as primary language, race, education, housing situation, and year the Safe Baby™ curriculum implemented were significantly associated with safe infant sleep practices. Bearing this in mind, FL MIECHV can tailor safe sleep education, messaging, and strategies to support participants at highest risk. Recent adoption of the Safe Baby™ curriculum, and associated staff training, was an important factor influencing parents’ infant sleep practices.

The pandemic caused by the new coronavirus Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is currently affecting more than 200 countries. The most lethal clinical presentation is respiratory insufficiency, requiring attention in intensive care units (ICU). The most susceptible people are over 60 years old with comorbidities. The health systems organization may represent a transcendental role in survival.Objective: To analyze the correlation of sociodemographic factors, comorbidities and health system organization variables with survival in cases infected by SARS-CoV-2 during the first 7 months of the pandemic in Mexico.Methods: The cohort study was performed in a health system public basis from March 1st to September 30th, 2020. The included subjects were positive for the SARS-CoV-2 test, and the target variable was mortality in 60 days. The risk variables studied were: age, sex, geographic distribution, comorbidities, health system, hospitalization, and access to ICU. Bivariate statistics (X2-test), calculation of fatality rates, survival analyses and adjustment of confusing variables with Cox proportional-hazards were performed.Results: A total of 753,090 subjects were analyzed, of which the 52% were men. There were 78,492 deaths (10.3% of general fatality and 43% inpatient). The variables associated with a higher risk of hospital mortality were age (from 60 years onwards), care in public sectors, geographic areas with higher numbers of infection and endotracheal intubation without management in the ICU.Conclusions: The variables associated with a lower survival in cases affected by SARS-CoV-2 were age, comorbidities, and respiratory insufficiency (with endotracheal intubation without care in the ICU). Additionally, an interaction was observed between the geographic location and health sector where they were treated.

Study Design: Retrospective cohort study. Objective: The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in late December 2019 has spread globally resulting in a pandemic of respiratory illness. The purpose of this study is to understand the impact of the first 6 months of the COVID-19 pandemic on the epidemiology of maxillofacial trauma at an urban trauma center. Methods: The study sample was derived from the population of patients who presented for evaluation and management of maxillofacial injuries at TriStar Skyline Medical Center in Nashville, Tennessee beginning March 1, 2020 and ending August 31, 2020, compared to the same period in 2019. Descriptive and bivariate statistics were calculated for study variables in each cohort with significance set at P < .05. Results: The number of subjects in the 2020 cohort (n = 212) was 4.2% higher than the 2019 cohort (n = 203). Volume decreased 24.5% during the initial phase of the pandemic with a 36.1% increase in volume occurring during the reopening phase (P = .003). Volume related to interpersonal decreased 52.4% during the initial phase of the pandemic with a rebound increase of 30% during reopening (P = .005). Conclusion: The first case of COVID-19 presented in Nashville, Tennessee in early March 2020. Over the next 6 months, periods of lockdown and reopening transpired. The volume of maxillofacial trauma decreased during the initial 3-months of the pandemic and rebounded to volumes greater than the year prior.
