This finding is a first step toward delineating the neuronal circuity underlying paternal care and may have implications for treating abnormalities in paternal care associated with paternal postpartum depression or paternal abuse.SIGNIFICANCE STATEMENT Paternal behavior is essential for offspring survival and development in some mammalian species. However, the circuit mechanisms underlying the paternal brain are poorly understood. We show that manipulation of paraventricular nucleus of the hypothalamus (PVN) to ventral tegmental area (VTA) oxytocin (OT) projections as well as VTA to nucleus accumbens (NAc) DA projections promote paternal behaviors. Inhibition the PVN to VTA OT pathway reduces DA release in the NAc during pup licking and grooming. PVN to NAc OT circuit is also essential for paternal behaviors. Our findings identify two new neural circuits that modulate paternal behaviors.
Prognostication tools that report personalized mortality risk and survival could improve discussions about end-of-life and advance care planning. We sought to develop and validate a mortality risk model for older adults with diverse care needs in home care using self-reportable information - the Risk Evaluation for Support Predictions for Elder-Life in the Community Tool (RESPECT).
Using a derivation cohort that comprised adults living in Ontario, Canada, aged 50 years and older with at least 1 Resident Assessment Instrument for Home Care (RAI-HC) record between Jan. 1, 2007, and Dec. 31, 2012, we developed a mortality risk model. The primary outcome was mortality 6 months after a RAI-HC assessment. We used proportional hazards regression with robust standard errors to account for clustering by the individual. We validated this algorithm for a second cohort of users of home care who were assessed between Jan. 1 and Dec. 31, 2013. We used Kaplan-Meier survival curves to estimate the observed risk of death ntification of palliative and end-of-life care needs in a diverse older adult population receiving home care.
The RESPECT mortality risk prediction tool that makes use of readily available information can improve the identification of palliative and end-of-life care needs in a diverse older adult population receiving home care.
Studies demonstrated that adolescent e-cigarette use is associated with subsequent tobacco smoking, commonly referred to as the
. However, most studies only investigated gateways from e-cigarettes to tobacco smoking. This study replicates a cornerstone study revealing a positive association between both adolescent e-cigarette use and subsequent tobacco use; and tobacco and subsequent e-cigarette use in the Netherlands and Flanders.
The longitudinal design included baseline (n=2839) and 6-month (n=1276) and 12-month (n=1025) follow-up surveys among a school-based cohort (mean age 13.62). Ten high schools were recruited as a convenience sample. The analyses involved (1) associations of baseline e-cigarette use and subsequent tobacco smoking among never smokers; (2) associations of e-cigarette use frequency at baseline and tobacco smoking frequency at follow-up; and (3) the association of baseline tobacco smoking and subsequent e-cigarette use among non-users of e-cigarettes.
Consistent with prior findings, baseline e-cigarette use was associated with higher odds of tobacco smoking at 6-month (OR=1.89; 95% CI 1.05 to 3.37) and 12-month (OR=5.63; 95% CI 3.04 to 10.42) follow-ups. More frequent use of e-cigarettes at baseline was associated with more frequent smoking at follow-ups. Baseline tobacco smoking was associated with subsequent e-cigarette use (OR=3.10; 95% CI 1.58 to 6.06 at both follow-ups).
Our study replicated the positive relation between e-cigarette use and tobacco smoking in both directions for adolescents. This may mean that the gateway works in two directions, that e-cigarette and tobacco use share common risk factors, or that both mechanisms apply.

To evaluate the impact of COVID-19 plus a temporary ban on the sale of tobacco and vaping products, on smoking cessation in South Africa, by reviewing research surveys conducted while the prohibition was in place.
An internet search was conducted on 20 August 2020, using the key words 'South Africa', 'survey', 'poll', 'smoking', 'cigarettes', 'tobacco", 'vaping', and 'COVID-19'. There were no language restrictions. Additional studies were identified through press reports. Only studies conducted between March and August 2020 were included.
Four surveys which reported on smokers quitting behaviour were included. None had been published in a peer reviewed journal. The heterogeneity of the data did not allow pooling. Support for the ban on tobacco sales amongst smokers varied from 6% to 36%. Similarly, there were inconsistent findings about quitting behaviour. Nationally, between 16% to 49% of smokers reported not smoking during the ban.
Cigarette smoking in SA dropped during the 2020 COVID-19 lockdown, but the estimates were inconsistent, probably because of survey design. There was evidence that the lockdown achieved the fastest rate of decline in smoking prevalence in the country's history. The true extent of the fall though is uncertain. Prevalence studies post lockdown, using probability sampling, may more accurately show how many people quit smoking.

Regulatory compliance in the retail environment is integral to the success of tobacco control. We assessed compliance among naswar (smokeless tobacco product widely used in South Asia) vendors with tobacco control laws. We also assessed their awareness of tobacco-related harms and policies and perceived effect of policies on their sales.
We surveyed 286 naswar vendors in three districts of the Khyber Pakhtunkhwa province of Pakistan. We recruited general and specialty vendors from urban and rural areas through multistage cluster sampling. Compliance was measured for promotion, sale to/by minors and tax paid on naswar. We used logistic regression analyses for assessing the association between the outcome variables (awareness of tobacco harms and laws, perceptions about the effect of policies on business and compliance with laws) and their predictors.
Most vendors (70%) were aware of tobacco-related harms of naswar. Although educated vendors were more aware of tobacco control policies, the greatest awareness was for a ban on sales to/by minors (21% overall). The majority of vendors (76%) violated this policy (measured by self-report), and violations were more common among rural than urban vendors (OR 2.27, 95% CI 1.05 to 4.96). Most vendors (71%) violated a ban on promotion of naswar. Vendors perceived tax increases and sales ban to/by minors as most detrimental for business.
There was poor awareness and compliance among naswar vendors in Pakistan with tobacco control laws. find more This study finds potential areas for policy interventions that can reduce urban/rural disparities in implementation of and compliance with tobacco control laws.

COVID-19 has exploited the inequities within the US housing system. Examining the association between housing and health during the pandemic is imperative to reducing health inequities and improving population health.
We analysed 957 714 responses from the Household Pulse Survey Study, collected between April and July 2020. Using survey-weighted multivariable regression analyses, we assessed the relationships between housing tenure and health, both on average and over time, as well as how these relationships were moderated by COVID-19-related hardships including job loss, food insecurity and inability to afford housing-related costs. We controlled for a variety of potential socioeconomic and demographic confounding factors.
We found that housing tenure was significantly associated with both self-rated health and mental distress. Compared with homeowners without mortgage debt, homeowners with mortgage debt reported worse self-rated health (β=-0.13; 95% CI -0.15 to -0.12, p<0.001) and greater mental distress (β=0.50; 95% CI 0.44 to 0.55, p<0.001). Renters also reported worse self-rated health (β=-0.18; 95% CI -0.20 to -0.16, p<0.001) and greater mental distress (β=0.76; 95% CI 0.69 to 0.83, p<0.001) than homeowners without mortgage debt. Across all tenure groups, self-rated health decreased (β=-0.007; 95% CI -0.011 to -0.004, p<0.001) and mental distress increased (β=0.05; 95% CI 0.05 to 0.06, p<0.001) over this period. Additionally, time and COVID-19-related hardships compounded differences in health status between homeowners and renters.
These results add to a limited body of evidence suggesting that, during this period, housing instability and COVID-19-related hardships have contributed to an increase in health inequities in the USA.

This patient had a pre-existing inflammatory disease, having recently developed ulcerative colitis antenatally. Five days prior to admission, she had tested positive asymptomatically on a SARS-CoV-2 reverse-transcriptase PCR nasopharyngeal swab. The positive swab result was confirmed on admission. Clinical examination revealed bilaterally exaggerated knee reflexes, lower limb weakness and positive Babinski's sign. Sensation was impaired at L4 and L5 dermatomes and absent at S1 and S2. MRI findings suggested longitudinal extensive transverse myelitis, with multiple regions of patchy hyperintensity seen in the thoracic region of the spinal cord both centrally and peripherally. She was started on a course of intravenous corticosteroids and improvement was seen both clinically and on repeat imaging. This case demonstrates a rare complication to an asymptomatic COVID-19 infection and explores the potential neurotropic properties of COVID-19.Ventilator-associated pneumonia (VAP) is one of the leading cause of mortality and morbidity in critically ill patients on mechanical ventilation. We report a case of VAP caused by Providencia rettgeri in a postoperative 58-year-old man with prepyloric perforation. The patient's ICU stay was complicated by VAP. As the organism was carbapenem resistant, high-dose extended infusion of meropenem along with cefepime was started. Early identification and treatment helped in successful weaning of the patient from the ventilator. Providencia is an emerging nosocomial pathogen with an increase in resistance pattern. This case highlights the rarity and importance of Providencia as a cause of VAP.
