This story reflects a personal narrative of a graduate student who experienced a disturbing incident during Mardi Gras in New Orleans, shedding light on the enduring issue of racism. The author's journey to graduate school and the challenges faced along the way provide context for the pivotal moment of racial discrimination. The narrative then shifts to the author's decision to prioritize education over anger, highlighting the sacrifices made to protect their future as a graduate student. The incident serves as a stark reminder that, despite personal achievements and aspirations, racial prejudice persists. In conclusion, the author calls for resilience and focus in the pursuit of personal goals while acknowledging the ongoing struggle against racism and other forms of discrimination in society. This personal story serves as a poignant reminder of the challenges faced by individuals and the need for continued efforts to combat systemic intolerance.

Research among adolescents exploring the association between depressive symptoms and aggression has produced inconsistent findings. This study investigated the prevalence of clinically significant (current major depressive episode) and subthreshold depressive symptoms in a general population sample of adolescents from Northern Russia and explored their association with aggression and anger, while controlling for comorbid mental health problems. The sample consisted of 2600 participants, aged 13-17 years (59.5% female; 95.7% ethnic Russian). Symptoms of a current major depressive episode, types of anger and aggression (anger rumination, trait anger, physical, verbal and social aggression) and comorbid problems (posttraumatic stress, alcohol use, anxiety, and hyperactivity/impulsivity) were assessed by means of self-reports. The prevalence of a clinically significant depressive episode in the past month was 3.5%, while for subthreshold depression it was 21.6%. All anger and aggression variables, as well as comorbid problems increased together with increasing levels of depression. The association between overt aggressive behavior and depression was primarily explained by comorbid mental health problems, whereas anger rumination and social aggression had more direct associations with depression, independent of comorbidity. Among adolescents with depression, boys reported higher levels of social and verbal aggression and of anger rumination than girls. The results of this study suggest that interventions aiming to reduce aggressive behavior in adolescents should consider depression and its comorbid conditions.

Nudges are means to influence the will formation of people to make specific choices more likely. My focus is on nudges that are supposed to improve the health condition of individuals and populations over and above the direct prevention of disease. I point out epistemic and moral problems with these types of nudges, which lead to my conclusion that health-enhancing nudges fail. They fail because we cannot know which choices enhance individual health-properly understood in a holistic way-and because health-enhancing nudges are often themselves bad for our health. They can be bad for our health because they assume inferior agency in their targets and accordingly regularly lead to appropriate resentment and anger-strong emotions which go along with an increased risk of health impairments. Briefly, health-enhancing nudges fail because they are based on persistent ignorance and on a presumptuous attitude.

Impaired spermatogenesis and male infertility are common manifestations associated with mitochondrial diseases, yet the underlying mechanisms linking these conditions remain elusive. In this study, we demonstrate that mice deficient for the mitochondrial intra-membrane rhomboid protease PARL, a recently reported model of the mitochondrial encephalopathy Leigh syndrome, develop early testicular atrophy caused by a complete arrest of spermatogenesis during meiotic prophase I, followed by degeneration and death of arrested spermatocytes. This process is independent of neurodegeneration. Interestingly, genetic modifications of PINK1, PGAM5, and TTC19 - three major substrates of PARL with important roles in mitochondrial homeostasis - fail to reproduce or modify this severe phenotype, indicating that the spermatogenic arrest arises from distinct molecular pathways. We further observed severe abnormalities in mitochondrial ultrastructure in PARL-deficient spermatocytes, along with prominent electron transfer chain defects, disrupted coenzyme Q (CoQ) biosynthesis, and metabolic rewiring. These mitochondrial defects are associated with a germ cell-specific decrease in GPX4 expression leading arrested spermatocytes to ferroptosis - a regulated cell death modality characterized by uncontrolled lipid peroxidation. Our results suggest that mitochondrial defects induced by PARL depletion act as an initiating trigger for ferroptosis in primary spermatocytes through simultaneous effects on GPX4 and CoQ - two major inhibitors of ferroptosis. These findings shed new light on the potential role of ferroptosis in the pathogenesis of mitochondrial diseases and male infertility warranting further investigation.

BACKGROUND
Opioid-free anesthesia is increasingly being adopted to reduce opioid consumption, but its impact on early postoperative recovery after major surgery has not been evaluated in comparative trials. The hypothesis was that an opioid-free anesthesia protocol would enhance the early quality of recovery for patients undergoing scheduled major surgery under general anesthesia.
METHODS
The SOFA study was a monocentric, randomized, controlled, assessor- and patient-blinded clinical trial conducted from July 10, 2021, to February 12, 2022. The eligible population included male and female patients undergoing scheduled major surgery, excluding bone procedures, that typically require opioids for postoperative pain management. Patients in the intervention group received a combination of at least two drugs among ketamine, lidocaine, clonidine, and magnesium sulfate, without opioids for anesthesia. The standard group received opioids. The primary outcome was early postoperative quality of recovery, assessed by Quality of Recovery-15 score at 24 h after surgery. Secondary outcomes were Quality of Recovery-15 at 48 and 72 h after surgery, incidence of chronic pain, and quality of life at 3 months.
RESULTS
Of the 136 randomized patients, 135 were included in the primary analysis (mean age, 45.9 ± 15.7 yr; 116 females [87.2%]; 85 underwent major plastic surgery [63.9%]), with 67 patients in the opioid-free anesthesia group and 68 in the standard group. The mean Quality of Recovery-15 at 24 h was 114.9 ± 15.2 in the opioid-free anesthesia group versus 108.7 ± 18.1 in the standard group (difference, 6.2; 95% CI, 0.4 to 12.0; P = 0.026). Quality of Recovery-15 scores also differed significantly at 48 h (difference, 8.7; 95% CI, 2.9 to 14.5; P = 0.004) and at 72 h (difference, 7.3; 95% CI, 1.6 to 13.0; P = 0.013). There were no differences in other secondary outcomes. No major adverse events were noticed.
CONCLUSIONS
The opioid-free anesthesia protocol improved quality of recovery after major elective surgery in a statistically but not clinically significant manner when compared to standard anesthesia.
