Abstract
BACKGROUND SAGE-324/BIIB124 is an investigational positive allosteric modulator of GABAA receptors. OBJECTIVE KINETIC (NCT04305275), a double-blind, randomized, placebo-controlled, phase 2 study, evaluated SAGE-324/BIIB124 in individuals with essential tremor (ET). METHODS Individuals aged 18 to 80 years were randomly assigned 1:1 to orally receive 60 mg of SAGE-324/BIIB124 or placebo once daily for 28 days. The primary endpoint was change from baseline in The Essential Tremor Rating Assessment Scale-Performance Subscale (TETRAS-PS) Item 4 (upper-limb tremor) at day 29 with SAGE-324/BIIB124 versus placebo. RESULTS Between May 2020 and February 2021, 69 U.S. participants were randomly assigned to receive SAGE-324/BIIB124 (n = 34) or placebo (n = 35). There was a significant reduction from baseline in TETRAS-PS Item 4 at day 29 with SAGE-324/BIIB124 versus placebo (least squares mean [standard error]: -2.31 [0.401] vs. -1.24 [0.349], P = 0.0491). The most common treatment-emergent adverse events included somnolence, dizziness, fatigue, and balance disorder. CONCLUSION These results support further development of SAGE-324/BIIB124 for potential ET treatment. © 2024 Sage Therapeutics, Inc and The Authors.

Abstract
INTRODUCTION The literature on the effect of head injuries on the risk of PD is inconclusive. Some researchers have hypothesized that studies that have seen an effect are simply capturing injury related to pre-clinical PD. However in animal models brain inflammation, which can be initiated by head trauma, has been shown to produce PD-like effects. Furthermore, animal studies have found that early life inflammation in particular is of relevance for PD pathology. METHODS We conducted an unmatched case-control study of 379 neurologist confirmed PD patients and 230 controls from the greater Boston, Massachusetts area with questionnaire data on history of head injury and other covariates. We used multivariable logistic regression to estimate adjusted odds ratios (OR) and their corresponding 95% confidence intervals (CI) for PD. RESULTS When we excluded injuries that occurred less than 10 years prior to the diagnosis of PD (in order to avoid reverse causation), we found an increased risk of PD associated with a head injury that resulted in a loss of consciousness, but it did not reach statistical significance (OR = 1.57; 95% CI = 0.89-2.80). We found a significant (p = 0.04) effect of age at first head injury. For every 5 year earlier age at first head injury with loss of consciousness the OR for PD was 1.37 (95% CI: 1.01-1.86). CONCLUSION Our results suggest that head injury in early life increases the risk of PD.

Abstract
Issuance of national policy guidance is a critical step to ensure quality HIV-TB (human immunodeficiency virus-tuberculosis) coordination and programme implementation. From the database of the Joint United Nations Programme on HIV/AIDS (UNAIDS), we reviewed 62 national HIV and TB guidelines from 23 high-burden countries for recommendations on HIV testing for TB patients, criteria for initiating antiretroviral therapy (ART) and the Three I's for HIV/TB (isoniazid preventive treatment [IPT], intensified TB case finding and TB infection control). We used UNAIDS country-level programme data to determine the status of implementation of existing guidance. Of the 23 countries representing 89% of the global HIV-TB burden, Brazil recommends ART irrespective of CD4 count for all people living with HIV, and four (17%) countries recommend ART at the World Health Organization (WHO) 2013 guidelines level of CD4 count ⩿500 cells/mm(3) for asymptomatic persons. Nineteen (83%) countries are consistent with WHO 2013 guidelines and recommend ART for HIV-positive TB patients irrespective of CD4 count. IPT is recommended by 16 (70%) countries, representing 67% of the HIV-TB burden; 12 recommend symptom-based screening alone for IPT initiation. Guidelines from 15 (65%) countries with 79% of the world's HIV-TB burden include recommendations on HIV testing and counselling for TB patients. Although uptake of ART, HIV testing for TB patients, TB screening for people living with HIV and IPT have increased significantly, progress is still limited in many countries. There is considerable variance in the timing and content of national policies compared with WHO guidelines. Missed opportunities to implement new scientific evidence and delayed adaptation of existing WHO guidance remains a key challenge for many countries.

Abstract
BACKGROUND Research using reconstructed exposure histories has suggested an association between heavy metal exposures, including lead, and Parkinson's disease (PD), but the only study that used bone lead, a biomarker of cumulative lead exposure, found a nonsignificant increase in risk of PD with increasing bone lead. OBJECTIVES We sought to assess the association between bone lead and PD. METHODS Bone lead concentrations were measured using 109Cd excited K-shell X-ray fluorescence from 330 PD patients (216 men, 114 women) and 308 controls (172 men, 136 women) recruited from four clinics for movement disorders and general-community cohorts. Adjusted odds ratios (ORs) for PD were calculated using logistic regression. RESULTS The average age of cases and controls at bone lead measurement was 67 (SD = 10) and 69 (SD = 9) years of age, respectively. In primary analyses of cases and controls recruited from the same groups, compared with the lowest quartile of tibia lead, the OR for PD in the highest quartile was 3.21 [95% confidence interval (CI), 1.17-8.83]. Results were similar but slightly weaker in analyses restricted to cases and controls recruited from the movement disorders clinics only (fourth-quartile OR = 2.57; 95% CI, 1.11-5.93) or when we included controls recruited from sites that did not also contribute cases (fourth-quartile OR = 1.91; 95% CI, 1.01-3.60). We found no association with patella bone lead. CONCLUSIONS These findings, using an objective biological marker of cumulative lead exposure among typical PD patients seen in our movement disorders clinics, strengthen the evidence that cumulative exposure to lead increases the risk of PD.

Abstract
We report a 74-year-old woman with opsoclonus, myoclonus, ataxia, and encephalopathy who had small-cell lung cancer and high titers of anti-Hu antibody in her serum. At autopsy, there were perivascular inflammatory infiltrates in the brainstem, putamen, and meninges overlying the orbital frontal cortex. Immunohistochemical studies showed the expression of the Hu antigens by the tumor and the presence of deposits of anti-Hu IgG in the patient's cortex, brainstem, and cerebellum, suggesting that anti-Hu immune response was related to the patient's clinical syndrome. This case of paraneoplastic opsoclonus, myoclonus, ataxia, and encephalopathy expands the spectrum of neurologic dysfunction associated with the anti-Hu antibody.

Abstract
Kappa receptor multiplicity is a complex area. We now present evidence from binding studies suggesting the existence of four kappa receptor subtypes. The guinea pig cerebellum contains high levels of U50,488-sensitive, or kappa 1, receptors. Kappa opiates (U50,488, tifluadom, Mr2034, Mr2266 and Win44,441) compete [3H]ethylketocyclazocine binding to kappa 1 receptors with kappa, values under 10 nM and Hill coefficients of approximately one, as does dynorphin A (kappa 1, 0.27 +/- 0.05 nM; Hill coefficient, 0.83 +/- 0.20, n = 4). However, competition studies with dynorphin B yield a Hill coefficient of 0.46 +/- 0.03 (n = 5) and nonlinear regression analysis of the competition curve is best fit by two sites. alpha-Neoendorphin Neoendorphin competition curves (Hill coefficient, 0.46 +/- 0.07; n = 3) also were best fit with two components. Competition studies with both alpha-neoendorphin and dynorphin B together suggest that both compounds label the same site with high affinity. Similar results were obtained using [3H]U69,593. Dynorphin B and alpha-neoendorphin competed binding with Hill coefficients of 0.45 +/- 0.04 (n = 3) and 0.59 +/- 0.09 (n = 3), respectively. These data suggest two subtypes of kappa 1 receptors in the guinea pig cerebellum: kappa 1a and kappa 1b. Classical kappa opiates and dynorphin A have high affinity for both subtypes whereas dynorphin B and alpha-neoendorphin label kappa 1b over 50-fold more potently than kappa 1a sites. [3H]Naloxone benzoylhydrazone [( 3H]NalBzoH) labels a novel, U50,488-insensitive kappa receptor subtype, kappa 3, in membranes from calf striatum, rat and mouse brain. We now have developed a relatively selective assay in calf striatum.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The actions of insulin, vanadate (V) and hydrogen peroxide (H2O2) on IGF-II binding and insulin receptor tyrosine kinase activity were studied in rat adipocytes. Incubating adipocytes with a combination of V plus H2O2 resulted in a potent synergistic effect on both the increase in IGF-II binding and the activation of the insulin receptor kinase. Catalase, which removes H2O2, abolished this synergism if added at the time of mixing of V plus H2O2 but not if added 10 min. later, suggesting that the formation of peroxide(s) of vanadate generated a potent insulin mimicker. The data support a critical role for the insulin receptor kinase in insulin action. The novel insulin-mimetic compound, a presumed peroxide of vanadate, could prove useful for investigating insulin action and may be valuable for treating insulin resistance.

Abstract
Preincubation of adipocytes with insulin (10 ng/ml) stimulated binding of IGF-II to maximal levels of 160% above controls. Vanadate also augmented IGF-II binding with an increase of 126% above controls at a concentration of 1 mM. Coincubation of vanadate (1 mM) with a maximal stimulatory dose of insulin (10 ng/ml) produced no additive effect. However, at submaximal doses of insulin (0.1 ng/ml) the effect of vanadate was additive. Amiloride, a potent inhibitor of the insulin receptor kinase, inhibited the effects of both vanadate and insulin. The data are consistent with an effect of vanadate via a similar sequence of steps to that of insulin; perhaps involving activation of the insulin receptor kinase.
