Opioid and stimulant attributed treatment admissions and fatal overdoses: Using national surveillance data to examine the intersection of race, sex, and polysubstance use, 1992-2020.

BACKGROUND: We use national surveillance data to evaluate race/ethnicity by sex/gender differences and trends in substance use treatment admissions and overdose deaths involving opioid and stimulant use. METHODS: We used data (1992-2019) from the Treatment Episode Dataset-Admissions to identify treatment admissions and the Center for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (1999-2020) to identify overdose deaths. We assessed treatment admissions and related drug overdose deaths per 100,000 adults by sex and race/ethnicity for opioid and stimulant groups: cocaine, opioid, methamphetamines, cocaine and opioid use, cocaine and methamphetamines, and opioid and methamphetamines. RESULTS: We found significant variations in treatment admissions and deaths by race/ethnicity and sex/gender. Cocaine-related treatment admissions and deaths were most prevalent among Non-Hispanic Black individuals over the study years, yet lower rates were evident among individuals from other racial/ethnic groups. Notably, Non-Hispanic Black men experienced larger increases in cocaine-only admissions than men of other racial/ethnic groups between 1992 and 2019. Men had higher opioid and stimulant treatment admissions and overdose deaths than women. We observed skyrocketing methamphetamine deaths among American Indian/Native Alaskan men and women from 1992 to 2019. DISCUSSION: Steep increases in overdose deaths fueled by methamphetamines among Non-Hispanic Native Americans and cocaine among Non-Hispanic Black individuals suggest a need for more effective interventions to curb stimulant use. Variations by race/ethnicity and sex/gender also suggest interventions should be developed through an intersectionality lens.

The association between diabetes medication and weight change in a non-surgical weight management intervention: an intervention cohort study.

AIM: To compare weight change in a lifestyle-based weight management programme between participants taking weight-gaining, weight-neutral/loss and mixed diabetes medications. METHODS: Electronic health records for individuals (≥ 18 years) with Type 2 diabetes who had been referred to a non-surgical weight management programme between February 2008 and May 2014 were studied. Diabetes medications were classified into three categories based on their effect on body weight. In this intervention cohort study, weight change was calculated for participants attending two or more sessions. RESULTS: All 998 individuals who took oral diabetes medications and attended two or more sessions of weight management were included. Some 59.5% of participants were women, and participants had a mean BMI of 41.1 kg/m2 (women) and 40.2 kg/m2 (men). Of the diabetes medication combinations prescribed, 46.0% were weight-neutral/loss, 41.3% mixed and 12.7% weight-gaining. The mean weight change for participants on weight-gaining and weight-neutral/loss diabetes medications respectively was -2.5 kg [95% confidence interval (CI) -3.2 to -1.8) and -3.3 kg (95% CI -3.8 to -2.9) (P = 0.05) for those attending two or more sessions (n = 998). Compared with those prescribed weight-neutral medications, participants prescribed weight-gaining medication lost 0.86 kg less (95% CI 0.02 to 1.7; P = 0.045) in a model adjusted for age, sex, BMI and socio-economic status. CONCLUSIONS: Participants on weight-neutral/loss diabetes medications had a greater absolute weight loss within a weight management intervention compared with those on weight-gaining medications. Diabetes medications should be reviewed ahead of planned weight-loss interventions to help ensure maximal effectiveness of the intervention.

Process evaluation of a cluster-randomised controlled trial of multi-component weight management programme in adults with intellectual disabilities and obesity.

BACKGROUND: Providing effective weight management to adults with intellectual disabilities is necessary to challenge the high rates of obesity. The aim of this process evaluation was to explore the feasibility of conducting a full-scale clinical trial of the TAKE 5 multi-component weight management programme. METHODS: The study was a 12-month pilot cluster-randomised controlled trial. Adults with intellectual disabilities and obesity were randomised to either TAKE 5, which included an energy deficit diet (EDD) or Waist Winners Too, based on health education principles. A mixed-methods process evaluation was conducted focussing on the reach, recruitment, fidelity, implementation, dose (delivered/received) and context. RESULTS: The study successfully recruited adults with intellectual disabilities. Both weight management programmes were delivered with high fidelity and implemented as intended. Only one weight management programme, TAKE 5, demonstrated potential efficacy in reducing body weight and body composition. The effectiveness was largely attributed to the EDD and social support from carers. CONCLUSIONS: The extensive process evaluation illustrated that a full-scale trial of a multi-component programme including an EDD is feasible and an acceptable approach to weight management for adults with intellectual disabilities and obesity.

Presence of obesity is associated with lower mortality in elderly patients with implantable cardioverter defibrillator.

BACKGROUND: Higher body mass index (BMI) is associated with greater prevalence of cardiovascular risk factors, yet an inverse relationship between obesity and survival after cardiovascular events has been described. It is unclear whether a similar relationship exists for patients with implantable cardioverter defibrillators (ICDs) at high risk for mortality. We aimed to assess the impact of BMI on mortality and cardiovascular hospitalization in patients with ICD. METHODS: Patients who underwent ICD implantation in 2010-2011 were divided into normal (<25 kg m-2), overweight (25-29.9 kg m-2) and obese (⩾30 kg m-2) groups based on BMI. Clinical parameters were compared and long-term outcomes were determined using χ2 test, Wilcoxon's rank-sum test, logistic regression models and Kaplan-Meier curves. RESULTS: Of 904 patients (mean age 67±13 years), 26% had normal BMI, 32% were overweight and 42% were obese. No significant baseline differences in ventricular ejection fraction, ICD for primary or secondary prevention, history of heart failure, syncope or cardiac arrest existed. Despite a greater prevalence of diabetes, hypertension and prior myocardial infarction, the obese and overweight groups had lower mortality (10.1% and 7.9%, respectively) than the normal group (22.9%, P<0.001). On multivariate logistic regression, BMI in the obese and overweight range (odds ratio (OR): 0.35; 95% confidence interval (CI): 0.21-0.58 and OR: 0.25; 95% CI: 0.13-0.40, respectively) was protective against mortality, whereas history of diabetes (OR: 2.01; 95% CI: 1.30-3.09), myocardial infarction (OR: 1.76; 95% CI: 1.11-2.80), heart failure (OR: 3.88; 95% CI: 1.56-9.66), stroke (OR: 3.19; 95% CI: 1.63-6.23) and history of cardiac arrest (OR: 2.65; 95% CI: 1.37-5.15) were independent risk factors for higher mortality. CONCLUSIONS: A paradoxical relationship between BMI and mortality risk is present in elderly patients with ICD at high risk of sudden death with a lower mortality in obese or overweight patients than in those with normal BMI.

SerpinB2 regulates stromal remodelling and local invasion in pancreatic cancer.

Pancreatic cancer has a devastating prognosis, with an overall 5-year survival rate of ~8%, restricted treatment options and characteristic molecular heterogeneity. SerpinB2 expression, particularly in the stromal compartment, is associated with reduced metastasis and prolonged survival in pancreatic ductal adenocarcinoma (PDAC) and our genomic analysis revealed that SERPINB2 is frequently deleted in PDAC. We show that SerpinB2 is required by stromal cells for normal collagen remodelling in vitro, regulating fibroblast interaction and engagement with collagen in the contracting matrix. In a pancreatic cancer allograft model, co-injection of PDAC cancer cells and SerpinB2-/- mouse embryonic fibroblasts (MEFs) resulted in increased tumour growth, aberrant remodelling of the extracellular matrix (ECM) and increased local invasion from the primary tumour. These tumours also displayed elevated proteolytic activity of the primary biochemical target of SerpinB2-urokinase plasminogen activator (uPA). In a large cohort of patients with resected PDAC, we show that increasing uPA mRNA expression was significantly associated with poorer survival following pancreatectomy. This study establishes a novel role for SerpinB2 in the stromal compartment in PDAC invasion through regulation of stromal remodelling and highlights the SerpinB2/uPA axis for further investigation as a potential therapeutic target in pancreatic cancer.

Attrition and weight loss outcomes for patients with complex obesity, anxiety and depression attending a weight management programme with targeted psychological treatment.

The objective of the study is to investigate the effect of baseline anxiety and depression, using different definitions for caseness, on attrition and weight outcomes following a multidisciplinary weight management programme. The study design is a prospective observational study. The Hospital Anxiety and Depression Scale (HADS) was used to measure anxiety and depression with 'caseness' scoring ≥11 and severity ≥14. The participants were all patients who began a weight management programme between 1 October 2008 and 30 September 2009 (n = 1838). The setting was the Glasgow and Clyde Weight Management Service (GCWMS), a specialist multidisciplinary service, which aims to achieve a minimum of ≥5 kg weight loss. The results were as follows: patients with HADS score ≥14 were referred to the integrated psychology service for psychological assessment or intervention. Patients with caseness (HADS ≥11) for anxiety (33%) and depression (27%) were significantly younger, heavier, more socio-economically deprived and a higher proportion was female. There was a significant positive correlation between HADS anxiety and depression scores and increasing body mass index (r(2) = 0.094, P < 0.001 and r(2) = 0.175, P < 0.001, respectively). Attendance and completion was lower throughout follow-up amongst patients with anxiety or depression. More patients with HADS score ≥11 achieved ≥5 kg or ≥5% weight loss and by 12 months those with anxiety had a significantly higher mean weight loss (P = 0.032). Participants who scored for severe anxiety (HADS ≥14) achieved similar weight loss to those without, whilst participants who scored for severe depression achieved significantly greater weight loss than non-cases at 3, 6 and 12 months of follow-up (P < 0.01). Despite a less favourable case-mix of risk-factors for poor weight loss, patients who scored caseness for severe anxiety or depression and were offered additional psychological input achieved similar or better weight loss outcomes.

Have early postoperative complications from laparoscopic rectal cancer surgery improved over the past 20 years?

AIM: Laparoscopic rectal cancer surgery has been increasingly used since 1991 following the publication of the first case series. Since then, several studies have confirmed that laparoscopic surgery for rectal cancer is challenging with associated morbidity and mortality. The aim of this study was to determine if the rates of early postoperative complications in laparoscopic rectal cancer surgery have improved over the past 20 years. METHOD: A literature search of the EMBASE and MEDLINE databases between August 1991 and August 2011 was conducted using the keywords laparoscopy, rectal cancer and postoperative complications. Data were analysed using linear regression ANOVA performed in GNUMERICS software. RESULTS: Ninety-seven studies were included for analysis. Over the last 20 years there has been no significant change in the rate of any early postoperative complications (anastomotic leak, conversion, sexual, urinary or faecal dysfunction, wound infection, overall morbidity or mortality). However, in the last 3 years, the rate of positive resection margins has decreased significantly (P = 0.01). CONCLUSION: There was no evidence of a statistically significant change in early postoperative complications until 3 years ago. This may reflect the inherent morbidity associated with rectal surgery regardless of the approach used, the limitations of the current laparoscopic instrumentation or the relatively long learning curve. With increasing experience, a repeat analysis in the near future following the publication of ongoing randomized clinical trials might show improved outcomes.

US Hemophilia Treatment Center population trends 1990-2010: patient diagnoses, demographics, health services utilization.

For several decades, US government agencies have partially supported regional networks of Hemophilia Treatment Centers (HTC). HTC multidisciplinary teams provide comprehensive and coordinated diagnosis, treatment, prevention, education, outreach and surveillance services to improve the health of people with genetic bleeding disorders. However, national data are scarce on HTC-patient population trends and services. The aim of the study was to examine national trends over the past 20 years in patient diagnoses, demographics and health services utilization among the Health Resources and Services Administration (HRSA) and Centers for Disease Control and Prevention (CDC)-supported HTC network. Diagnoses, demographics and health services utilization data from 1990 to 2010 were aggregated from all HTCs using the Hemophilia Data Set (HDS). From 1990 to 2010, the HTC population grew 90% from 17 177 to 32 612. HTC patients with von Willebrand's disease increased by 148%, females by 346%, Hispanic patients by 236% and African Americans by 104%. Four thousand and seventy-five deaths were reported. From 2002 to 2010, annual comprehensive evaluations grew 38%, and persons with severe haemophilia on a home intravenous therapy programme rose 37%. In 2010, 46% of patients were less than 18 years vs. 24% for the general US population. The Hemophilia Data Set documents the growth and diversity of the US Hemophilia Treatment Center Network's patient population and services. Despite disproportionate deaths due to HIV, the HTC patient base grew faster than the general US population. The HDS is a vital national public health registry for this rare-disorder population.

Environmental contaminants and human health in the Canadian Arctic.

The third Canadian Arctic Human Health Assessment conducted under the Canadian Northern Contaminants Program (NCP), in association with the circumpolar Arctic Monitoring and Assessment Programme (AMAP), addresses concerns about possible adverse health effects in individuals exposed to environmental contaminants through a diet containing country foods. The objectives here are to: 1) provide data on changes in human contaminant concentrations and exposure among Canadian Arctic peoples; 2) identify new contaminants of concern; 3) discuss possible health effects; 4) outline risk communication about contaminants in country food; and 5) identify knowledge gaps for future contaminant research and monitoring. The nutritional and cultural benefits of country foods are substantial; however, some dietary studies suggest declines in the amount of country foods being consumed. Significant declines were found for most contaminants in maternal blood over the last 10 years within all three Arctic regions studied. Inuit continue to have the highest levels of almost all persistent organic pollutants (POPs) and metals among the ethnic groups studied. A greater proportion of people in the East exceed Health Canada's guidelines for PCBs and mercury, although the proportion of mothers exceeding these guidelines has decreased since the previous assessment. Further monitoring and research are required to assess trends and health effects of emerging contaminants. Infant development studies have shown possible subtle effects of prenatal exposure to heavy metals and some POPs on immune system function and neurodevelopment. New data suggest important beneficial effects on brain development for Inuit infants from some country food nutrients. The most successful risk communication processes balance the risks and benefits of a diet of country food through input from a variety of regional experts and the community, to incorporate the many socio-cultural and economic factors to arrive at a risk management decision that will be the most beneficial in Arctic communities.

Truncated form of VACM-1/cul-5 with an extended 3' untranslated region stimulates cell growth via a MAPK-dependent pathway.

We have sequenced a 4.9kb clone (KLB22) which shares 99% sequence homology with the rabbit vasopressin-activated calcium mobilizing (VACM-1) protein. The 5' terminus sequence of KLB22 cDNA (nucleotides 1-1961) is continuous and overlapping with nucleotides 1226-3186 of the VACM-1 cDNA sequence. The 3'UTR of KLB22 cDNA extends beyond the 3'UTR of VACM-1 by 2999nt. KLB22 cDNA encodes a 497 amino acid protein, which putatively begins at Met 284 of the 780 amino acid VACM-1 protein. The in vitro translation of KLB22 cDNA yields a 59kDa protein. When expressed in cos-1 cells, the truncated VACM-1 protein localizes to the nucleus. KLB22 cDNA transfected cells show increased growth rates and increased levels of phosphorylated MAPK when compared to the vector or to VACM-1 cDNA transfected cells. Finally, in vivo, KLB22 protein expression is tissue specific and can be detected in kidney and in heart atrium. These results suggest that truncated VACM-1 cDNA (KLB22) increases cell proliferation through a MAPK pathway.

Relationship between glutathione S-transferase M1, P1 and T1 polymorphisms and early onset prostate cancer.

There is evidence suggesting that polymorphic variations in the glutathione S-transferases (GSTs) are associated with cancer susceptibility. Inter-individual differences in cancer susceptibility may be mediated in part through polymorphic variability in the bioactivation and detoxification of carcinogens. The GSTs have been consistently implicated as cancer susceptibility genes in this context. The GST supergene family includes several loci with well characterized polymorphisms. Approximately 50% of the Caucasian population are homozygous for deletions in GSTM1 and approximately 20% are homozygous for deletions in GSTT1, resulting in conjugation deficiency of mutagenic electrophiles to glutathione. The GSTP1 gene has a polymorphism at codon 105 resulting in an Ile to Val substitution which consequently alters the enzymatic activity of the protein and this has been suggested as a putative high-risk genotype in various cancers. We investigated the relationship between GST polymorphisms and young onset prostate cancer in a case-control study. GSTM1, GSTT1 and GSTP1 genotypes were determined for 275 prostate cancer patients and for 280 geographically matched control subjects. We found no significant difference in the frequency of GSTM1 or GSTT1 null genotypes between cases and controls. GSTP1 genotype was, however, significantly associated with prostate cancer risk: the Ile/Ile homozygotes had the lowest risk and there was a trend in increasing the risk with the number of 105 Val alleles: Ile/Val odds ratio (OR)= 1.30 (95% FCI 0.99-1.69), Val/Val OR = 1.80 (95% FCI 1.11-2.91); Ptrend = 0.026. These results suggest that the GSTP1 polymorphism may be a risk factor for developing young onset prostate cancer. We also found that carrying more than one putative high-risk allele in the carcinogen metabolizing GST family was associated with an elevated risk for early onset prostate cancer (OR 2.48, 95% FCI 1.22-5.04, Ptrend = 0.017).

Stereotactic breast biopsy: a six-year surgical experience.

A retrospective review was done of all stereotactic breast biopsies performed at the Central Baptist Hospital Breast Center from February 1994 through December 1999. A total of 1,080 biopsies were performed in 1,026 patients, all by surgeons working independently. Masses were biopsied in 54% and calcifications in 40%. Eighteen percent of biopsies were malignant. The most common benign diagnosis was fibrocystic disease (72%), followed by fibroadenoma (19%), lymph node (2%), and papilloma (2%). The most common malignant diagnosis was invasive ductal carcinoma (40%) followed by ductal carcinoma in situ (32%) and mixed invasive and in situ ductal carcinoma (19%). A prebiopsy BI-RADS mammographic Category III was associated with a 2% incidence of malignancy; Category IV--17%; Category V--90%. Atypical ductal hyperplasia on stereotactic biopsy was upgraded to a malignant diagnosis after reexcision in 19% of the cases. The false-negative rate was 0.4% (sensitivity 99%) and the complication rate was 3%, mostly related to bleeding. Stereotactic biopsy is a safe and accurate technique for the minimally-invasive diagnosis of abnormal mammograms.

When your client has had an accident.

Accident victims often experience difficulty finding meaning and logic in their accident. Confusion and depression are frequently emotions that will be felt until resolution occurs. In many cases other individuals assist in this struggle for resolution. The nurse often has opportunity to provide suggestions and support as the client struggles to find meaning.

E-mail triage.

This article describes how hospital managers can use principles of triage when sending and receiving e-mail. It also discusses when e-mail should not be used, and when personal communication should occur.

Getting your nursing program in the "news".

Getting in the news usually needs to be a planned event with intentional actions and strategies. In most cases, news from the nursing program needs to be an administrative or faculty goal with a strategy for how this will occur. There must be a commitment to ensure that timely information is provided so that a news item can actually become reality. Most importantly, when newspapers and the media are provided with this information in a news release it must be written in a style that piques the interest of the editor and causes it to be selected as news (Perloff, 1997). If time is taken to interact with reporters and to understand how the media works, it can provide support to achieve the goals and outcomes of a nursing program.

The frequency of germ-line mutations in the breast cancer predisposition genes BRCA1 and BRCA2 in familial prostate cancer. The Cancer Research Campaign/British Prostate Group United Kingdom Familial Prostate Cancer Study Collaborators.

Predisposition to prostate cancer has a genetic component, and there are reports of familial clustering of breast and prostate cancer. Two highly penetrant genes that predispose individuals to breast cancer (BRCA1 and BRCA2) are known to confer an increased risk of prostate cancer of about 3-fold and 7-fold, respectively, in breast cancer families. Blood DNA from affected individuals in 38 prostate cancer clusters was analyzed for germ-line mutations in BRCA1 and BRCA2 to assess the contribution of each of these genes to familial prostate cancer. Seventeen DNA samples were each from an affected individual in families with three or more cases of prostate cancer at any age; 20 samples were from one of affected sibling pairs where one was < or = 67 years at diagnosis. No germ-line mutations were found in BRCA1. Two germ-line mutations in BRCA2 were found, and both were seen in individuals whose age at diagnosis was very young (< or = 56 years) and who were members of an affected sibling pair. One is a 4-bp deletion at base 6710 (exon 11) in a man who had prostate cancer at 54 years, and the other is a 2-bp deletion at base 5531 (exon 11) in a man who had prostate cancer at 56 years. In both cases, the wild-type allele was lost in the patient's prostate tumor at the BRCA2 locus. However, intriguingly, in neither case did the affected brother also carry the mutation. Germ-line mutations in BRCA2 may therefore account for about 5% of prostate cancer in familial clusters.

Luck: what the nurse should know about it and how it affects nursing situations.

Luck permeates every aspect of human behaviour. Thus, luck is an aspect of nursing care and client belief of which the nurse should be aware. Beliefs about luck will influence client compliance with recommendations for actions as well as influence actions the client selects in relation to health. Beliefs about luck will also influence actions the nurse may take when responding to clients.

Your best preparation for a good day's work: a good night's sleep.

Contrary to the manner in which a great many people seem to regard sleep, sleep is not a waste of time. Inadequate sleep, let alone chronic sleep deprivation and actual sleep disorders, leads to diminished quality of work and loss of productivity. As far as caregivers are concerned, inadequate sleep can affect dangerously their ability to function in critical situations. On the other hand, adequate sleep is needed if one is to function at one's potential best and sufficient sleep is also an effective hedge against the encroachment of job stresses. For one who is occasionally unable to get sufficient sleep, there are steps to be taken to improve the ability to rest. A good night's sleep invariably precedes a good day's work.

A dilemma of modern technology: managing e-mail overload.

In an amazingly short time, electronic mail (e-mail) has become one of the most powerful and useful communication mediums in the health care workplace. However, while e-mail has added new dimensions to the communication system, which are advantageous, a concomitant effect is e-mail overload. By implementing e-mail management technique, strategies information overload can be controlled and effective productivity promoted.

The effective voice mail message.

When used effectively, voice mail is an indispensable and powerful tool for the busy health services manager. On the other hand, misused or abused, voice mail can handicap the manager and cause frustration to all individuals involved in the communication interaction. By following guidelines for effective use of voice mail, the manager can maximize this important communication modality and enhance business finesse.
