One-third of opioid (OPI) overdose deaths involve concurrent benzodiazepine (BZD) use. Little is known about concurrent opioid and benzodiazepine use (OPI-BZD) most associated with overdose risk. We aimed to examine associations between OPI-BZD dose and duration trajectories, and subsequent OPI or BZD overdose in US Medicare.

Retrospective cohort study.

US Medicare.

Using a 5% national Medicare data sample (2013-16) of fee-for-service beneficiaries without cancer initiating OPI prescriptions, we identified 37 879 beneficiaries (age ≥ 65 = 59.3%, female = 71.9%, white = 87.6%, having OPI overdose = 0.3%).

During the 6 months following OPI initiation (i.e. trajectory period), we identified OPI-BZD dose and duration patterns using group-based multi-trajectory models, based on average daily morphine milligram equivalents (MME) for OPIs and diazepam milligram equivalents (DME) for BZDs. To label dose levels in each trajectory, we defined OPI use as very low (< 25 MME), low (25-50 MME), moderate (51-90p A, five trajectories (32.3% of the study cohort) were associated with increased 6-month OPI overdose risks E low OPI-high BZD [hazard ratio (HR) = 3.27, 95% confidence interval (CI) = 1.61-6.63]; F medium OPI-low BZD (HR = 4.04, 95% CI = 2.06-7.95); G very high OPI-high BZD (HR = 6.98, 95% CI = 3.11-15.64); H very high OPI-very high BZD (HR = 4.41, 95% CI = 1.51-12.85); and I very high OPI-low BZD (HR = 6.50, 95% CI = 3.15-13.42).

Patterns of concurrent opioid and benzodiazepine use most associated with overdose risk among fee-for-service US Medicare beneficiaries initiating opioid prescriptions include very high-dose opioid use (MME > 150), high-dose benzodiazepine use (DME > 40) or medium-dose opioid with low-dose benzodiazepine use.

Compare the risk of melanoma between initiators of rasagiline or other antiparkinsonian drugs (APDs) in a Parkinson's disease (PD) population.

A retrospective cohort study was conducted in the US Medicare claims research database (2006-2015) in adults aged ≥65 years with PD claims. Other APD initiators were randomly matched (41) to rasagiline initiators on age, sex, and cohort entry year. Cutaneous melanoma events were identified by a validated claims algorithm. Incidence rates (IRs), incidence rate ratios (IRRs), and Cox-adjusted hazard ratios (HRs) for melanoma comparing rasagiline with other APD initiators were calculated and analyzed by duration of study medication use and cumulative dose of rasagiline. Potential indicators of surveillance bias were explored.

Among 23 708 rasagiline initiators and 96 552 matched APD initiators, the crude IR of melanoma/100 000 person-years was 334.3 (95% confidence interval [CI], 291.5-381.6) and 208.2 (95% CI, 190.1-227.5), respectively (crude IRR 1.61; 95% CI, 1.3ng explanation for the observed results.

What is the central question of this study? What is the effect of hypobaric hypoxia on markers of exercise-induced intestinal injury and symptoms of gastrointestinal (GI) distress? What is the main finding and its importance? Exercise performed at 4300m of simulated altitude increased intestinal fatty acid binding protein (I-FABP), claudin-3 (CLDN-3) and lipopolysaccharide binding protein (LBP), which together suggest that exercise-induced intestinal injury may be aggravated by concurrent hypoxic exposure. Increases in I-FABP, LBP and CLDN-3 were correlated to exercise-induced GI symptoms, providing some evidence of a link between intestinal barrier injury and symptoms of GI distress.

We sought to determine the effect of exercise in hypobaric hypoxia on markers of intestinal injury and gastrointestinal (GI) symptoms. Using a randomized and counterbalanced design, nine males completed two experimental trials one at local altitude of 1585m (NORM) and one at 4300m of simulated hypobaric hypoxia (HYP). Particpost-exercise in HYP (10.8±1.2 to 13.9±2.8μgml

 ; P=0.006, d=1.12) but not NORM (11.3±1.1 to 11.7±0.9μgml

 ; P>0.99, d=0.32). I-FABP (d=0.85), CLDN-3 (d=0.95) and LBP (d=0.69) were all significantly higher post-exercise in HYP compared to NORM (P≤0.05). Overall GI discomfort was significantly correlated to ΔI-FABP (r=0.71), ΔCLDN-3 (r=0.70) and ΔLBP (r=0.86). These data indicate that cycling exercise performed in hypobaric hypoxia can cause intestinal injury, which might cause some commonly reported GI symptoms.

Neck carcinoma of unknown primary (CUP) is a frequent scenario. HDAC inhibitor review Transoral robotic mucosectomies (TORM) of pharynx have increased rate of primary identification, but come with cost of treatment delay.

We reviewed patients who underwent CUP protocol from 2014 to 2020. Patients with cervical nodes carcinoma and failure to localize a primary source were classified as CUP. We determined primary identification rate and postoperative complications.

We included 65 patients underwent TORM. Surgical approach consisted of lingual and/or palatine tonsillectomies. The primary detection rate was 49.2%. Average weight reduction was 2.5± 4.3kg. The average number of days from consultation to definitive treatment was 52.2± 18.3.

A systematic approach to patients with CUP showed a promising primary identification rate compared to panendoscopy alone. TORM carries a small risk of complications. The benefits of primary identification must be weighed with the morbidity and delay to definitive treatment.

Obesity disproportionately impacts Aboriginal and Torres Strait Islander children compared to non-Indigenous children. Aboriginal and Torres Strait Islander Health Workers (AHWs) in Queensland support the health of Aboriginal and Torres Strait Islander peoples. However, little is known about their perspectives and practices on addressing childhood obesity. The aim of this study was to investigate AHW perspectives and clinical practice behaviours with Aboriginal and Torres Strait Islander children and their families.

In a cross-sectional mixed-methods approach, a purpose-developed online survey (25 items) was distributed to the AHW workforce in Queensland (~100 AHWs). The survey explored [1] role characteristics, [2] current attitudes and beliefs about childhood obesity, [3] barriers to discussing weight management, [4] clinical practice behaviours and [5] demographic characteristics. Eight AHWs responding to the survey also participated in semi-structured telephone interviews to discuss their survey respoesity in Aboriginal and Torres Strait Islander communities.

AHWs report a willingness to address childhood obesity within their roles, however many find it difficult to raise the issue with families, with even fewer routinely undertaking obesity assessment practices. SO WHAT? These findings could inform training initiatives for AHWs to optimise screening, identification, referral, and treatment of childhood obesity in Aboriginal and Torres Strait Islander communities.

This study aimed to examine patients with facial nerve (VII) perineural spread (PNS) from cutaneous squamous cell carcinoma of the head and neck.

Retrospective analysis of patients managed by an Australian tertiary center between 2000 and 2019.

Seventy three patients were included. Most presented with recurrent disease (89.0%) and simultaneous trigeminal nerve (V) involvement (67.1%). Of the 55 patients (75.3%) who received curative intent treatment, 48 received surgery plus/minus post-operative radiotherapy. In these patients, 5-year disease-free survival, disease-specific survival, and overall survival was 50.7%, 68.7%, and 58.1%, respectively. Pathological nodal disease, involved margins, increasing VII zonal extent, and concurrent zone 2 V PNS significantly worsened outcomes.

High rates of recurrent disease reflects the importance of adequate treatment of the primary. Surgery and post-operative radiotherapy remains the mainstay treatment. Outcomes are improved in early-stage disease and with clear surgical margins, reinforcing the need for prompt diagnosis and intervention.

Therefore, identifying a safe and effective treatment strategy for PDAC is urgent. Lucidone is a natural compound extracted from the fruits of Lindera erythrocarpa Makino. However, the role of lucidone in PDAC inhibition remains unclear. In addition, high-mobility group box 1 (HMGB1) and receptor for advanced glycation end products (RAGE) are involved in multidrug resistance protein 1 (MDR1) regulation and GEM resistance. Thus, this study aimed to explore the function of lucidone in tumor cytotoxicity and chemosensitivity through the suppression of RAGE-initiated signaling in PDAC cells. The data showed that lucidone significantly promoted apoptotic cell death and inhibited the expression of autophagic proteins (Atg5, Beclin-1, LC3-II, and Vps34) and MDR1 by inhibiting the HMGB1/RAGE/PI3K/Akt axis in both MIA Paca-2 cells and MIA Paca-2GEMR cells (GEM-resistant cells). Notably, convincing data were also obtained in experiments involving RAGE-specific siRNA transfection. In addition, remarkable cell proliferation was observed after treatment with lucidone combined with GEM, particularly in MIA Paca-2GEMR cells, indicating that lucidone treatment enhanced chemosensitivity. Collectively, this study provided the underlying mechanism by which lucidone treatment inhibited HMGB1/RAGE-initiated PI3K/Akt/MDR1 signaling and consequently enhanced chemosensitivity in PDAC.Bifunctional fluorescent molecular oxoanion probes based on the benzoxadiazole (BD) chromophore are described which integrate a thiourea binding motif and a polymerizable 2-aminoethyl methacrylate unit in the 4,7-positions of the BD core. Concerted charge transfer in this electron donor-acceptor-donor architecture endows the dyes with strongly Stokes shifted (up to >250 nm) absorption and fluorescence. Binding of electron-rich carboxylate guests at the thiourea receptor leads to further analyte-induced red-shifts of the emission, shifting the fluorescence maximum of the complexes to ≥700 nm. Association constants for acetate are ranging from 1-5×105  M-1 in acetonitrile. Integration of one of the fluorescent probes through its polymerizable moiety into molecularly imprinted polymers (MIPs) grafted from the surface of submicron silica cores yielded fluorescent MIP-coated particle probes for the selective detection of antibiotics containing aliphatic carboxylate groups such as enoxacin (ENOX) at micromolar concentrations in highly polar solvents like acetonitrile.
