Pediatric Concerns Due to Expanded Cannabis Use: Unintended Consequences of Legalization

An “unintended consequence” of marijuana legalization is the impact on the pediatric population. From prenatal exposure to unintentional childhood exposures, through concerns of adolescence abuse and marijuana use for medicinal indications in children, marijuana exposure can affect pediatric patients at every stage in childhood. Regardless of the stage or reason of exposure, concerns exist about short-term and long-term consequences in a child’s physical and mental health. The use of cannabidiol (CBD) may have some benefit for the treatment of epilepsy, but emphasis needs to be on rigorous clinical trials to evaluate efficacy and safety. As more states allow both medical and recreational marijuana, availability and prevalence of use will likely increase and more surveillance and research is needed to evaluate the consequences on the pediatric population.     

Impact of surgery and radiation therapy on spinal high-grade gliomas: a population-based study

Cerebral radiation necrosis (CRN) is a known complication of radiation therapy. Treatment options are limited and include steroids, bevacizumab, and surgery. This study seeks to determine the safety of laser interstitial thermal therapy (LITT) for CRN and identify the pattern of post-ablation volume change over time. Patients undergoing LITT for tumor treatment at Henry Ford Hospital between November 2013 and January 2016 with biopsy-confirmed CRN were prospectively collected and retrospectively reviewed with attention to ablation volume, survival, demographic data, steroid dose, and complications. Imaging occurred at set intervals beginning pre-ablation. Ten patients with 11 ablations were evaluated. Four patients had a primary diagnosis of high-grade glioma, while six had metastatic lesions. An average of 86% of CRN volume was ablated. Ablation volume increased to 430% of initial CRN volume at 1–2 weeks before decreasing to 69% after 6 months. No patient had a decline in baseline neurological examination while in the hospital. Four patients developed delayed neurological deficits likely due to post-operative edema, of which three improved back to baseline. The 6-month survival was 77.8% and the 1-year survival was 64.8% based on Kaplan–Meier curve estimates. In this study, LITT was a relatively safe treatment for CRN, providing both a diagnostic and therapeutic solution for refractory patients. Significant increase in ablation volume was noted at 1–2 months, gradually decreasing in size to less than the original volume by 6 months. Further studies are needed to better define the role of LITT in the treatment of CRN.     

High serum folate is associated with brain atrophy in older diabetic people with vitamin B12 deficiency

Previous studies have reported the adverse cognitive effects of high folate status in older individuals with vitamin B12 (VB12) deficiency. Thus, the aim of this study was to investigate how high serum folate and VB12 deficiency could collaboratively aggravate neuronal degeneration. In total, 146 older non-demented diabetic individuals with an average age of 75 ± 3.9 were recruited. VB12 deficiency and high folate status were based on high serum methylmalonic acid (MMA) concentrations (> 0.3 μmol/L) and the serum folate concentration being in the top tertile (> 31.4 nmol/L) respectively. Among these subjects, there were 20 with elevated MMA and high folate. The structural magnetic resonance imaging data of these subjects were analyzed by performing flexible factorial analysis with the “folate level” and “MMA level” added as main effects, and the interaction effect of folate and VB12 on brain volume was evaluated. The results showed significant gray matter atrophy of the right middle occipital gyrus and the opercular part of the inferior frontal gyrus in subjects with a simultaneous high folate status and VB12 deficiency. Together with previous observational studies on cognitive function, this study lends support to the notion that high serum folate concentrations in older people with VB12 deficiency may be associated with increased neurodegeneration..     

Glycosylated hemoglobin-defined prediabetes and cardiovascular risk markers in rural India: the Nallampatti noncommunicable disease study

The aim of this study is to assess the associations between glycosylated hemoglobin in the prediabetes range and cardiovascular risk markers in a rural South Indian population. Local Ethics Committee approval and informed consent was obtained from all participants. Inclusion criteria were participants, aged ≥20 and ≤85 years, from Nallampatti, a classical farming village from Tamil Nadu State, India. Those with known history of diabetes were excluded from this analysis. All participants were administered a detailed questionnaire, had anthropometric measurements including height, weight, and waist circumference. Bloods were drawn for random blood glucose, glycosylated hemoglobin, nonfasting lipid profile, cystatin C, uric acid, and hemoglobin. All participants had carotid intima thickness done by high-resolution B-mode carotid ultrasound. Progressive hyperglycemia across the glucose tolerance continuum based on glycosylated hemoglobin levels in a rural South Indian population seems to be associated with worsening cardiovascular risk markers. A cut-off value of ≥6% (42 mmol/mol) seems to herald a much more significant increase in such markers. Long-term follow-up of this cohort for incident cardiovascular disease will help to substantiate the associations between glycosylated hemoglobin levels within the prediabetes range and cardiovascular disease in an Indian population. Evidence-based race-specific criteria for diagnosis of prediabetes and diabetes are the need of the hour for risk stratification and appropriate management.     

Do Meaning in life,Ideological Commitment,and Level of Religiosity,Related Adolescent Substance Abuse and Attitude?

The present study focuses on expanding and broadening the connection between meaning in life and psychoactive substance abuse. Since professional literature presents an individual’s meaning in life as an immunizing factor against substance abuse, the present study sought to examine the impact of level of religiosity and level of ideological-political commitment, through the prism of meaning in life, on the attitudes adopted by adolescents towards such abuse, and their actual use of the various substances. The findings of the study, in which 1032 Israeli adolescents aged 14 to 18 took part, supported the hypothesis whereby a high level of religiosity “immunizes” against psychoactive substance abuse. However, they also indicate that despite the negative approach to it among individuals with high levels of ideological commitment, no significant correlation can be found between ideological commitment and actual psychoactive substance abuse. The study findings underscore the importance of both religion and ideological commitment in the formation of meaning in life by youth, as well as the impact of social supervision and perceived norms in their environment, with regard to their willingness to attempt using psychoactive substances, and their actual use thereof. The study findings contribute both to research and practical application when constructing programs for the prevention of normative adolescent substance abuse.
