N-acetylcysteine inhalation improves the quality of life of patients with head and neck cancers who are receiving radiation therapy, without any specific side effect.This study examined how levels of neurotransmitters in the lateral prefrontal cortex (LPFC), a region underlying higher-order cognition, are related to the brain's intrinsic functional organization. Using magnetic resonance spectroscopy (MRS), GABA+ and Glx (glutamate + glutamine) levels in the left dorsal (DLPFC) and left ventral (VLPFC) lateral prefrontal cortex were obtained in a sample of 64 female adults (mean age = 48.5). We measured intrinsic connectivity via resting-state fMRI in three ways (a) via seed-based connectivity for each of the two spectroscopy voxels; (b) via the spatial configurations of 17 intrinsic networks defined by a well-known template; and (c) via examination of the temporal inter-relationships between these intrinsic networks. The results showed that different neurotransmitter indexes (Glx-specific, GABA+-specific, Glx-GABA+ average and Glx-GABA+ ratio) were associated with distinct patterns of intrinsic connectivity. Neurotransmitter levels in the left LPFC are mainly associated with connectivity of right hemisphere prefrontal (e.g., DLPFC) or striatal (e.g., putamen) regions, two areas of the brain connected to LPFC via large white matter tracts. While the directions of these associations were mixed, in most cases, higher Glx levels are related to reduced connectivity. Prefrontal neurotransmitter levels are also associated with the degree of connectivity between non-prefrontal regions. These results suggest robust relationships between the brain's intrinsic functional organization and local neurotransmitters in the LPFC which may be constrained by white matter neuroanatomy.

The aim of this study was to analyse whether the global trend in drug prescriptions for attention-deficit hyperactivity disorders (ADHD), as observed during the last years and often criticized as medicalization, have remained stable or shifted.

This observational study was based on a secondary analysis of data from a large German database including patients with an ADHD diagnosis between 2008 and 2018. this website Prescription data comprised all important ADHD drugs.

A total of 620 practices delivered data from a total of 77,504 patients (31% of them females) with a diagnosis of AHDH. Nearly 38% (29,396/77,504) of all patients received, at least, one prescription for an ADHS medicine between 2008 and 2018. The number of patients receiving a drug steadily increased annually until 2012 and then slowly fell, but unevenly distributed across the age groups. While the number of younger patients ( ≤ 16 years) receiving a prescription fell by 24% and the defined daily doses (DDDs) remained stable, the number of patients between 17 and 24years receiving a prescription increased by 113% and the DDDs by 150%. Respectively, the number of older adults (≥ 25years) with a prescriptionincreased by 355% and the DDDs by515%. Nearly one-third of older adults received an ADHD medicine only once.

The ever-increasing prescription of ADHD medicines stopped some years ago for children. ADHS and its pharmacological management are increasingly observed among older adolescents and adults, with a different pattern of drug persistence compared with children.

To examine whether there is a positive association between sexual dysfunction (SD) and different types of progestin-based contraceptives.

Nested case-control study in women of child-bearing age (15-45 years) from the IQVIA® Ambulatory electronic medical record database from 2008 to 2018. Cases defined by diagnosis of sexual dysfunction identified by international classification for disease clinical modification code 9th and 10th. Each case was matched to four controls and rates of prescriptions of the following were compared levonorgestrel intra-uterine device (IUD), progestin, and ethinyl estradiol (EE) combined oral contraceptive (COC) formulations including levonorgestrel, norgestimate, drospirenone, desogestrel, norethindrone, and norgestrel; etonogestrel vaginal ring; and medroxyprogesterone injection.

Overall, 6689 cases of patients with SD were matched to 26,756 matched controls. Compared with matched controls, more subjects with SD used levonorgestrel IUD (OR 1.24, 95% CI 1.08-1.44), EE-levonorgrgestrel. The small association size and lack of difference between drug formulations suggest a minimal impact of progestin-based contraceptives on sexual dysfunction.

Mizoribine (MZR) is an immunosuppressant for the prevention of allograft rejection in Asian countries, but the great variability in pharmacokinetics (PK) limits its clinical use. This study was to explore genetic and clinical factors that affect the MZR PK process.

Blood samples and clinical data were collected from 60 Chinese renal transplant recipients. MZR plasma concentration was measured at pre-dose (0h) and 0.5, 1, 2, 3, 4, 5, 6, 8, and 12h post-dose by high performance liquid chromatography with an ultraviolet detector. PK parameters were calculated by non-compartmental analysis. High-throughput sequenced single nucleotide polymorphism was applied screening possible genetic factors.

Extensive inter-individual MZR PK differences were reflected in the process of elimination (k

, CL/F, MRT and t

) and intestinal absorption (C

and T

), as well as in the dose-normalized exposure (AUC

/D). From 146 SNPs within 39 genes screened, AUC

/D was found higher in recipients with CREB1 rs11904814 TT than with G allele carriers (3.135 ± 0.928 versus 2.084 ± 0.379μghml

mg

, p = 0.007). Recipients with SLC28A3 rs10868138 TT had lower t

as compared to C allele carriers (0.728 ± 0.189 versus 0.951 ± 0.196h, p = 0.001). Serum creatinine (SCr) explained 35.5% of C

/D variability (p < 0.001). Pure effects of genotypes CREB1 and SLC28A3 were 13.7% (p = 0.004) and 17.5% (p = 0.001) for AUC

/D and t

, respectively. When additionally taking SCr into models, CREB1 and SLC28A3 genotypes explained 20.0% (p = 0.038) and 46.5% (p < 0.001) of AUC

/D and t

variability, respectively.

CREB1 and SLC28A3 genotypes, as well as SCr, are identified as determinants in predicting inter-individual MZR PK differences in renal transplant recipients.
