Years lived with disability (YLDs) for 1160 sequelae of 289 diseases and injuries 1990-2010: a systematic analysis for the Global Burden of Disease Study 2010
TL;DR: Prevalence and severity of health loss were weakly correlated and age-specific prevalence of YLDs increased with age in all regions and has decreased slightly from 1990 to 2010, but population growth and ageing have increased YLD numbers and crude rates over the past two decades.

TL;DR: This study summarizes the potential factors that may affect the risk of acne presentation or severe acne and can help researchers and clinicians to understand the epidemiology of acne and severe acne.
Abstract: A systematic review was conducted on epidemiology studies on acne obtained from a Web of Science search to study risk factors associated with acne presentation and severity. A strong association was observed between several risk factors – family history, age, BMI and skin type – and acne presentation or severity in multiple studies. The pooled odds ratio of 2.36 (95% CI 1.97–2.83) for overweight/obese BMI with reference to normal/underweight BMI and the pooled odds ratio of 2.91 (95% CI 2.58–3.28) for family history in parents with reference to no family history in parents demonstrate this strong association. In addition, a pooled odds ratio of 1.07 (95% CI 0.42–2.71) was obtained for sex (males with reference to females). However, the association between other factors, such as dietary factors and smoking, and acne presentation or severity was less clear, with inconsistent results between studies. Thus, further research is required to understand how these factors may influence the development and severity of acne. This study summarizes the potential factors that may affect the risk of acne presentation or severe acne and can help researchers and clinicians to understand the epidemiology of acne and severe acne. Furthermore, the findings can direct future acne research, with the hope of gaining insight into the pathophysiology of acne so as to develop effective acne treatments.

TL;DR: The perspective of DM is expanded by not only considering elevated blood glucose levels, but also including literature about the other important pathogenic mechanisms, such as insulin resistance, dyslipidemia, hypertension, and immune dysfunction.
Abstract: Diabetes mellitus (DM) is associated with several microvascular and macrovascular complications, such as retinopathy, nephropathy, neuropathy, and cardiovascular diseases. The pathogenesis of these complications is complex, and involves metabolic and hemodynamic disturbances, including hyperglycemia, insulin resistance, dyslipidemia, hypertension, and immune dysfunction. These disturbances initiate several damaging processes, such as increased reactive oxygen species (ROS) production, inflammation, and ischemia. These processes mainly exert their damaging effect on endothelial and nerve cells, hence the susceptibility of densely vascularized and innervated sites, such as the eyes, kidneys, and nerves. Since the oral cavity is also highly vascularized and innervated, oral complications can be expected as well. The relationship between DM and oral diseases has received considerable attention in the past few decades. However, most studies only focus on periodontitis, and still approach DM from the limited perspective of elevated blood glucose levels only. In this review, we will assess other potential oral complications as well, including: dental caries, dry mouth, oral mucosal lesions, oral cancer, taste disturbances, temporomandibular disorders, burning mouth syndrome, apical periodontitis, and peri-implant diseases. Each oral complication will be briefly introduced, followed by an assessment of the literature studying epidemiological associations with DM. We will also elaborate on pathogenic mechanisms that might explain associations between DM and oral complications. To do so, we aim to expand our perspective of DM by not only considering elevated blood glucose levels, but also including literature about the other important pathogenic mechanisms, such as insulin resistance, dyslipidemia, hypertension, and immune dysfunction.

TL;DR: In this paper, a better understanding of droughts and other extreme events as sources of vulnerability is needed, including the patterns of risks and how these could change over time, the reasons for any changes, how these risks could affect human health and well-being, and the longer-term consequences of extreme events for vulnerability.
Abstract: The health risks of climate change arise from the interactions of the hazards associated with a changing climate (e.g. increases in the frequency and intensity of extreme weather and climate events, such as drought), the communities exposed to those hazards, the susceptibility of communities to adverse health impacts when exposed, and the capacity to prepare for and cope with the hazard. However, there is a very limited understanding of how extreme weather and climate events could themselves be sources of vulnerability. Drought is used as an example of an extreme event that can simultaneously be a current hazard and can directly and indirectly influence future vulnerability. A better understanding of droughts and other extreme events as sources of vulnerability is needed, including (i) the patterns of risks and how these could change over time, (ii) the reasons for any changes, (iii) how these risks could affect human health and well-being, and (iv) the longer-term consequences of extreme events for vulnerability. This knowledge will become increasingly important for managing risks to health as the frequency and intensity of extreme weather and climate events increase with climate change.

TL;DR: Increased PFC connectivity in early-course patients is identified, predictive of symptoms and diagnostic classification, but less evidence for “hypoconnectivity,” and the initial hyperconnectivity, which may decrease longitudinally, could have prognostic and therapeutic implications.
Abstract: Strong evidence implicates prefrontal cortex (PFC) as a major source of functional impairment in severe mental illness such as schizophrenia. Numerous schizophrenia studies report deficits in PFC structure, activation, and functional connectivity in patients with chronic illness, suggesting that deficient PFC functional connectivity occurs in this disorder. However, the PFC functional connectivity patterns during illness onset and its longitudinal progression remain uncharacterized. Emerging evidence suggests that early-course schizophrenia involves increased PFC glutamate, which might elevate PFC functional connectivity. To test this hypothesis, we examined 129 non-medicated, human subjects diagnosed with early-course schizophrenia and 106 matched healthy human subjects using both whole-brain data-driven and hypothesis-driven PFC analyses of resting-state fMRI. We identified increased PFC connectivity in early-course patients, predictive of symptoms and diagnostic classification, but less evidence for “hypoconnectivity.” At the whole-brain level, we observed “hyperconnectivity” around areas centered on the default system, with modest overlap with PFC-specific effects. The PFC hyperconnectivity normalized for a subset of the sample followed longitudinally (n = 25), which also predicted immediate symptom improvement. Biologically informed computational modeling implicates altered overall connection strength in schizophrenia. The initial hyperconnectivity, which may decrease longitudinally, could have prognostic and therapeutic implications.

TL;DR: Notably, major depressive disorder is a common disorder, widely distributed in the population, and usually associated with substantial symptom severity and role impairment, and while the recent increase in treatment is encouraging, inadequate treatment is a serious concern.
Abstract: ContextUncertainties exist about prevalence and correlates of major depressive
disorder (MDD).ObjectiveTo present nationally representative data on prevalence and correlates
of MDD by Diagnostic and Statistical Manual of Mental Disorders,
Fourth Edition (DSM-IV) criteria, and on study
patterns and correlates of treatment and treatment adequacy from the recently
completed National Comorbidity Survey Replication (NCS-R).DesignFace-to-face household survey conducted from February 2001 to December
2002.SettingThe 48 contiguous United States.ParticipantsHousehold residents ages 18 years or older (N = 9090) who responded
to the NCS-R survey.Main Outcome MeasuresPrevalence and correlates of MDD using the World Health Organization's
(WHO) Composite International Diagnostic Interview (CIDI), 12-month severity
with the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR),
the Sheehan Disability Scale (SDS), and the WHO disability assessment scale
(WHO-DAS). Clinical reinterviews used the Structured Clinical Interview for DSM-IV.ResultsThe prevalence of CIDI MDD for lifetime was 16.2% (95% confidence interval
[CI], 15.1-17.3) (32.6-35.1 million US adults) and for 12-month was 6.6% (95%
CI, 5.9-7.3) (13.1-14.2 million US adults). Virtually all CIDI 12-month cases
were independently classified as clinically significant using the QIDS-SR,
with 10.4% mild, 38.6% moderate, 38.0% severe, and 12.9% very severe. Mean
episode duration was 16 weeks (95% CI, 15.1-17.3). Role impairment as measured
by SDS was substantial as indicated by 59.3% of 12-month cases with severe
or very severe role impairment. Most lifetime (72.1%) and 12-month (78.5%)
cases had comorbid CIDI/DSM-IV disorders, with MDD
only rarely primary. Although 51.6% (95% CI, 46.1-57.2) of 12-month cases
received health care treatment for MDD, treatment was adequate in only 41.9%
(95% CI, 35.9-47.9) of these cases, resulting in 21.7% (95% CI, 18.1-25.2)
of 12-month MDD being adequately treated. Sociodemographic correlates of treatment
were far less numerous than those of prevalence.ConclusionsMajor depressive disorder is a common disorder, widely distributed in
the population, and usually associated with substantial symptom severity and
role impairment. While the recent increase in treatment is encouraging, inadequate
treatment is a serious concern. Emphasis on screening and expansion of treatment
needs to be accompanied by a parallel emphasis on treatment quality improvement.
