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: Opportunities exist for accelerating development, particularly in fungal asthma, and to treat chronic and invasive aspergillosis.
Abstract: About 1.2 billion people worldwide are estimated to suffer from a fungal disease ( 1 , 2 ). Most are infections of the skin or mucosa, which respond readily to therapy, but a substantial minority is invasive or chronic and difficult to diagnose and treat. An estimated 1.5 to 2 million people die of a fungal infection each year, surpassing those killed by either malaria or tuberculosis ( 3 ). Most of this mortality is caused by species belonging to four genera of fungi: Aspergillus, Candida, Cryptococcus , and Pneumocystis. Although great strides were made in the 1990s, drug development has largely stalled since then. Opportunities exist for accelerating development, particularly in fungal asthma, and to treat chronic and invasive aspergillosis.

TL;DR: The information the authors have suggests that low-concentration topical capsaicin is without meaningful effect beyond that found in placebo creams; given the potential for bias from small study size, this makes it unlikely that it has any meaningful use in clinical practice.
Abstract: Background
Topical creams with capsaicin are used to treat peripheral neuropathic pain. Following application to the skin capsaicin causes enhanced sensitivity, followed by a period with reduced sensitivity and, after repeated applications, persistent desensitisation. High-concentration (8%) capsaicin patches were developed to increase the amount of capsaicin delivered; rapid delivery was thought to improve tolerability because cutaneous nociceptors are 'defunctionalised' quickly. The single application avoids noncompliance. Only the 8% patch formulation of capsaicin is available, with a capsaicin concentration about 100 times greater than conventional creams.
High-concentration topical capsaicin is given as a single patch application to the affected part. It must be applied under highly controlled conditions, normally under local anaesthetic, due to the initial intense burning sensation it causes. The benefits are expected to last for about 12 weeks, when another application might be made.
Objectives
To review the evidence from controlled trials on the efficacy and tolerability of topically applied, high-concentration (8%) capsaicin in chronic neuropathic pain in adults.
Search methods
We searched CENTRAL, MEDLINE, EMBASE and clinicaltrials.gov to December 2012.
Selection criteria
Randomised, double-blind, placebo-controlled studies of at least six weeks' duration, using topical capsaicin to treat neuropathic pain.
Data collection and analysis
Two review authors independently assessed trial quality and validity, and extracted data on numbers of participants with pain relief (clinical improvement) after at least six weeks, and with local skin reactions. We calculated risk ratio and numbers needed to treat to benefit (NNT) and harm (NNH). We sought details of definition of pain relief and specific adverse events.
Efficacy outcomes reflecting long-duration pain relief after a single drug application were from the patient global impression of change (PGIC) at specific points, usually eight and 12 weeks. We regarded these outcomes as first-tier evidence. We regarded average pain scores over weeks 2 to 8 and 2 to 12 and the number and/or percentage of participants with pain intensity reduction of at least 30% or at least 50% over baseline as second-tier evidence.
Main results
We included six studies, involving 2073 participants; they were of generally good reporting quality; the control was 0.04% topical capsaicin to help maintain blinding. Efficacy outcomes were inconsistently reported between studies, however, resulting in analyses for most outcomes being based on less than complete data.
Four studies involved 1272 participants with postherpetic neuralgia. All efficacy outcomes were significantly better than control. At both eight and 12 weeks there was a significant benefit for high-concentration over low-concentration topical capsaicin for participants reporting themselves to be much or very much better, with point estimates of the NNTs of 8.8 (95% confidence interval (CI) 5.3 to 26) and 7.0 (95% CI 4.6 to 15) respectively. More participants had average 2 to 8-week and 2 to 12-week pain intensity reductions over baseline of at least 30% and at least 50% with active treatment than control, with NNT values between 10 and 12.
Two studies involved 801 participants with painful HIV-neuropathy. In a single study the NNT at 12 weeks for participants to be much or very much better was 5.8 (95% CI 3.8 to 12). Over both studies more participants had average 2 to 12-week pain intensity reductions over baseline of at least 30% with active treatment than control, with an NNT of 11.
Local adverse events were common, but not consistently reported. Serious adverse events were no more common with active treatment (4.1%) than control (3.2%). Adverse event withdrawals did not differ between groups, but lack of efficacy withdrawals were somewhat more common with control than active treatment, based on small numbers of events. No deaths were judged to be related to study medication.
Authors' conclusions
High-concentration topical capsaicin used to treat postherpetic neuralgia and HIV-neuropathy generates more participants with high levels of pain relief than does control treatment using a much lower concentration of capsaicin. The additional proportion who benefit over control is not large, but for those who do obtain high levels of pain relief there are additional improvements in sleep, fatigue, depression and an improved quality of life. High-concentration topical capsaicin is therefore similar to other therapies for chronic pain. In this case, the high cost of single and repeated applications suggest that high-concentration topical capsaicin is likely to be used when other available therapies have failed, and that it should probably not be used repeatedly without substantial documented pain relief. Even when efficacy is established, there are unknown risks, especially on epidermal innervation, of repeated application of long periods.

TL;DR: Mental disorders were found to be commonplace with a prevalence level comparable to that found in the 1998 predecessor study but several further adjustments will have to be made for a sound methodological comparison between the studies.
Abstract: Background and objectives The German health interview and examination survey for adults (DEGS1) with the mental health module (DEGS1-MH) is the successor to the last survey of mental disorders in the general German population 15 years ago (GHS-MHS). This paper reports the basic findings on the 12-month prevalence of mental disorders, associated disabilities and self-reported healthcare utilization. Methods A representative national cohort (age range 18-79 years, n = 5,317) was selected and individuals were personally examined (87.5 % face to face and 12.5 % via telephone) by a comprehensive clinical interview using the composite international diagnostic interview (CIDI) questionnaire. Results The overall 12-month prevalence of mental disorders was 27.7 % with substantial differences between subgroups (e.g. sex, age, socioeconomic status). Mental disorders were found to be particularly impairing (elevated number of disability days). Less than 50 % of those affected reported to be in contact with health services due to mental health problems within the last 12 months (range 10-40 % depending on the number of diagnoses). Conclusions Mental disorders were found to be commonplace with a prevalence level comparable to that found in the 1998 predecessor study but several further adjustments will have to be made for a sound methodological comparison between the studies. Apart from individual distress, elevated self-reported disability indicated a high societal disease burden of mental disorders (also in comparison with many somatic diseases). Despite a relatively comprehensive and well developed mental healthcare system in Germany there are still optimisation needs for treatment rates.

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.
