Evaluating the effectiveness of a universal eHealth school-based prevention programme for depression and anxiety, and the moderating role of friendship network characteristics, Andrews et al. 2022: (n=2,000) universal eHealth school-based, CBT-informed, preventive programme for depression and anxiety is no better than control
School-based mindfulness training in early adolescence: what works, for whom and how in the MYRIAD trial?, Montero-Marin et al. 2022: (n=8,000) school-based mindfulness training vs control resulted in worse scores on depression risk and well-being in students at risk of mental health problems both at post intervention and 1-year follow-up (though not clinically relevant); higher dose and reach associated with worse function post intervention

Reflections on Alnylam, Maraganore 2022
Epidemiology/pathophysiology:
The serotonin theory of depression: a systematic umbrella review of the evidence, Moncrieff et al. 2022: comprehensive review of the major strands of research on serotonin shows there is no convincing evidence that depression is associated with, or caused by, lower serotonin concentrations or activity; most studies found no evidence of reduced serotonin activity in people with depression compared to people without, and methods to reduce serotonin availability using tryptophan depletion do not consistently lower mood in volunteers
Prospective biomarkers of major depressive disorder: a systematic review and meta-analysis, Kennis et al. 2022: no biomarkers (neuroimaging, GI, immunology, neurotrophic, neurotransmitters, hormones, and oxidative stress) except cortisol predict MDD (but effect disappears after correcting for disease state) i.e. no evidence for any causal biomarkers of depression
Quantifying Deviations of Brain Structure and Function in Major Depressive Disorder Across Neuroimaging Modalities, Winter et al. 2022: (n=1,800) group differences in neuroimaging markers explained less than 2% variance
An exercise-inducible metabolite that suppresses feeding and obesity, Li et al. 2022: exercise stimulates the production of N-lactoyl-phenylalanine (Lac-Phe) in CNDP2+ cells (e.g. macrophages, monocytes) that suppresses feeding and obesity
High Intelligence is not a Risk Factor for Mental Health Disorders, Williams et al. 2022: Individuals with high g-factors had less general anxiety (OR=0.69) and PTSD (OR=0.67), were less neurotic (β=-0.12), less socially isolated (OR=0.85), and were less likely to have experienced childhood stressors and abuse, adulthood stressors, or catastrophic trauma (OR=0.69-0.90); they did not differ in any other mental health disorder or trait
Genome-wide association study of antisocial personality disorder, Rautiainen et al. 2022: first study showing genome-wide significant (n=6,000) and replicable (n=4,000) findings on genetic variants associated with any personality disorder
Ehlers-Danlos syndrome: prevalence and outcomes in gender affirming surgery - a single institution experience, Najafian et al. 2022: the prevalence of Ehlers-Danlos syndrome diagnosis in patients undergoing gender-affirming surgeries is 132x the highest reported prevalence in the general population
The function of efference copy signals: Implications for symptoms of schizophrenia, Pynn 2013: it is hypothesised that when one speaks, a copy of the efferent signals is sent to the auditory cortex where sensation is suppressed only when the anticipated voice matches the actual voice (sensory reafferent); failure in this “corollary discharge” may explain schizophrenic patients’ deficits in discriminating between self generated vs externally generated auditory sensations
Covid
Vaccine effectiveness of one, two, and three doses of BNT162b2 and CoronaVac against COVID-19 in Hong Kong: a population-based observational study, McMenamin et al. 2022: (n=21,000) in HK where no prior outbreak (hence population immunity) confounds analysis, 2-dose BioNTech’s efficacy against severe disease or death in adults aged 60+ was 89·3% [95% CI 86·6–91·6]) compared with CoronaVac’s 69·9% [64·4–74·6]; 3 doses (third being BioNTech) 97·9% [97·3–98·4]
The molecular epidemiology of multiple zoonotic origins of SARS-CoV-2, Pekar et al. 2022: SARS-CoV-2 emerged from at least 2 separate cross-species transmission events into humans, the first around 18 November 2019, and another within weeks of the first zoonotic transmission

Prospective Evaluation of Parent Distress Following Pediatric Burns and Identification of Risk Factors for Young Child and Parent Posttraumatic Stress Disorder, De Young et al. 2014: (n=120) concurrent parent PTSS was a significant predictor of child PTSS at 1 month (β=0.51, p<0.001) and 6 months (β=0.19, p<0.05); parents' responses to a traumatic event may play a particularly important role in a young child's psychological recovery
Sarah Constantin: Personalized Medicine For Real: “personalised medicine” is many things — healthcare optimisation for basically healthy people (superficial personalisation on top of generic lifestyle advice), stratifying treatment based on genes (we don’t know enough about how genes affects treatment effects), preventing medical error (building a “smart hospital” that runs on checklists, statistical prediction rules, outcomes monitoring, and other evidence-based practices is epically hard), AI diagnosis (irreducible dependence on how you frame the problem), connecting patients with experimental therapies (consulting/software to match patients with clinical trials), changing clearly mismatched standard practice to match scientific evidence (hard to scale), and of course n=1 translational medicine for rare diseases (requires actual therapeutic development expertise)

Longevity:
The relationship between epigenetic age and the hallmarks of aging in human cells, Kabacik et al. 2022: epigenetic ageing is affected by nutrient sensing, mitochondrial function, stem cell exhaustion and altered cell–cell communication, but not cellular senescence, telomere attrition and genomic instability; implies ageing is due to two types of mechanisms: deterministic (epigenetic ageing) and stochastic (wear and tear)
Oocytes maintain ROS-free mitochondrial metabolism by suppressing complex I, Rodríguez-Nuevo et al. 2022: oocytes formed during fetal development manage to avoid reactive oxygen species (ROS) during dormancy by suppressing mitochondrial complex I
Female reproductive life span is extended by targeted removal of fibrotic collagen from the mouse ovary, Umehara et al. 2022: fibrosis due to mitochondrial dysfunction within the ovarian stromal compartment imapir oocyte release; antifibrosis drugs (pirfenidone and BGP-15) eliminate fibrotic collagen and restore ovulation in reproductively old and obese mice
Clonal dynamics of haematopoiesis across the human lifespan, Mitchel et al. 2022: haematopoietic stem cells or multipotent progenitors (HSC/MPPs) accumulated a mean of 17 mutations/year after birth and lost 30 base pairs/year of telomere length; the prevalence of clones at more than 1% variant allele fraction (VAF) is universal after age 70 (not 10–20% prevalent as previously estimated); the number of expanded clones per individual is 10–20 (not 1–2); the fraction of overall haematopoiesis accounted for by expanded clones is 30–60% (not 3–5%); clonal expansions have their origins in mutations that occurred decades earlier (not in old age)
Alcohol consumption and telomere length: Mendelian randomization clarifies alcohol’s effects, Topiwala et al. 2022: (n=250k) higher genetically-predicted alcohol use disorder (inverse variance-weighted β = −0.06, 95% CI: −0.10 to −0.02, p = 0.001) was associated with shorter telomere length

Adrian D’Souza: On Sri Lanka's Economic Crisis: the Majority Sinhala Buddhists (Sri Lankan Army) has been accused of widespread rape and massacring civilians vs the minority Tamils (Tamil Tigers militant group) invented suicide bombing, used child soldiers and gorilla warfare; Rajapaksa ended the 30-year civil war tried to fix the economy with massive spending (on white elephant constriction projects for populist reasons) through high interest commerical loans (only 15% was Chinese-owned debt); Islamist terroist suicide bombing in 2019 led to increased nationalism; the massively popular Rajapaska implemented populist legislation e.g. cutting income tax and VAT, discontinuing automatic fuel pricing; Rajapaska wanted to save valuable foreign currency by switching away from heavily subsidized imported fertilizer, which destroyed Sri Lanka’s primary export of tea crop and tanked domestic rice production by 20% in just the first 6 months, causing further haemorrhage of foreign currency reserve (forced to import $450 million worht of rice); since the pandemic the Rajapaskas didn’t want to to make the structural reforms that an 18th IMF bail out would entail, instead tried to print money and establish price controls on fuel and food; ultimately, the current crisis is the fault of the citizens of Sri Lanka voting for populist politicians

Anton Howes: Age of Invention: Why wasn't the Steam Engine Invented Earlier? Part I: the usual story of the invention of the steam engine goes: Evangelista Torricelli demonstration in the 1640s both that vacuums are possible and that the atmosphere has a weight, leading to water-raising engines invented in the 1690s by Thomas Savery, which exploited atmospheric pressure by condensing steam; however Howes discovers that Salomon de Caus, as early as 1615, had very probably made a solar-powered version of Savery’s engine; see also Part II: the history of mechanical exploitation of condensation extends back to ancient times (along with alchemists)
2.8 Economics/Business/Finance
No evidence for nudging after adjusting for publication bias, Maier et al. 2022
Business Retreats and Sanctions Are Crippling the Russian Economy, Sonnenfeld et al. 2022: imports have collapsed (widespread domestic supply shortages); domestic production has come to a complete standstill (lost companies representing 40% of its GDP); oil is selling at a steep discount; natural gas futures in Europe are up about 700% year-over-year; Russia is more dependent on its counterparties e.g. China in terms of trade share

The Effect of Incarceration on Mortality, Norris et al. 2022: mortality risk (especially murders, overdoses, and natural causes) halves during the period of incarceration and no detectable effect on post-release mortality risk i.e. incarceration increases longevity
The Distributional Impact of the Minimum Wage in the Short and Long Run, Hurst et al. 2022: in the short run, a large increase in the minimum wage has a small effect on employment and therefore increases the labour income of the workers who were earning less than the new minimum wage; in the long run, the minimum wage has perverse distributional implications in that it reduces the employment, income, and welfare of precisely the low-income workers it is meant to help
Why do people stay poor? Balboni et al. 2021: large-scale, randomised asset (cows) transfer and an 11-year panel on 6000 households in extreme poverty in Bangladesh shows large transfers creating jobs for the poor are effective in getting people out of poverty traps
