Dying whilst on probation: a scoping review of mortality amongst those under community justice supervision.

AIM: Data suggest mortality rates of those under community justice services such as probation or parole have been increasing year on year. Little is known about why and how these individuals are dying. This scoping review explores the causes and contributing factors of mortality in those under community justice supervision. METHODS: Studies published between 2011 and 2021 were identified across CINAHL, Embase, Global Health, Ovid Medline and PsycINFO. Articles were included if they presented original data on either mortality rates among those under community justice supervision or risk factors associated with the mortality of those under community justice supervision. RESULTS: Searches identified 101 unique articles of which 13 were included in the review. Articles were representative of five countries. All articles were either retrospective reviews or retrospective cohort studies. The studies fell into the categories of all-cause mortality, self-inflicted deaths or drug-related deaths. CONCLUSION: Mortality rates of those under community justice supervision were found to be consistently higher than mortality rates for the general population regardless of cause of death. Factors identified as affecting mortality included history of drug use, history of self-harm and previous imprisonment including length of time in custody and experience of hospitalisation or solitary confinement while in custody.

Identifying the public health needs of a UK probation cohort: a cross-sectional analysis.

BACKGROUND: The health needs of those under probation are likely high, but they have received very little public health attention. Limited evidence exists on the public health needs and interventions to support this cohort. METHODS: Surveys were completed by 257 people on probation as part of a local health needs assessment. Results were compared with the general population responses from the National Survey for Wales (2021-22). RESULTS: People on probation were 4.2 times more likely to self-report not-good general health (fair, bad or very bad) than the general population (adjusted Odds Ratio [aOR] 4.2, 95% Confidence Intervals [CI] 3.2-5.4). The odds of having a mental health condition were over eight times higher than the general population (aOR 8.8, 95% CI 6.8-11.4). Prevalence of smoking (52%), drug use (60%), attention-deficit hyperactivity disorder (21%), autism (4%) and dyslexia (15%) were all higher than the general population. General Practitioner usage and hospital stays were higher, but dentist or optician usage lower than the general population (P < 0.05). Emergency departments were accessed by 35%, with 9% frequenting them three or more times. CONCLUSIONS: People on probation have poorer self-reported health, higher prevalence of unhealthy behaviours and higher accessing of reactive health services than the general population.

Quantifying cardiovascular disease risk and heart age predictions for men in the prison environment.

OBJECTIVES: Cardiovascular disease (CVD) and associated risk factors within the prison population often present at a younger age in this cohort. Given CVD is largely preventable, it warrants investigation to fully quantify this risk. This study explored the relative predicted 10-year CVD risk and examined the calculated heart age in a representative sample of male individuals aged 25-84 years within the prison environment. STUDY DESIGN: This was a cross-sectional study. METHODS: Data were collected on 299 men who underwent a cardiometabolic risk assessment in HMP Parc, Bridgend. The QRISK2 algorithm was used to calculate 10-year CVD risk, relative risk (to general population) and the predicted heart age of an individual. Between-group differences (prison population vs general community) in cardiovascular risk predictions (10-year CVD risk and heart age) were assessed. RESULTS: We observed that at all age groups, the relative risk of predicted 10-year CVD scores in the prison population was double that of the community risk (2.1 ± 0.6), and this was most apparent in the oldest age group (≥50 years: 17.0% compared to 8.8%; P < 0.001). Overall, the heart age of the sample was 7.5 (6.7-8.2) years higher than their own chronological age, and this difference increased to above 9 years in those aged ≥40 years. CONCLUSIONS: This study provides quantifiable evidence to the elevated CVD risk in prison. Heart age predictions were almost a decade higher in those aged ≥40 years. Lowering the screening age for CVD by around 5 years in the prison population should be considered.

Differences in the impact of precarious employment on health across population subgroups: a scoping review.

AIM: Precarious employment is known to be detrimental to health, and some population subgroups (young individuals, migrant workers, and females) are at higher risk of precarious employment. However, it is not known if the risk to poor health outcomes is consistent across population subgroups. This scoping review explores differential impacts of precarious employment on health. METHODS: Relevant studies published between 2009 and February 2019 were identified across PubMed, OVID Medline, PsycINFO, and Scopus. Articles were included if (1) they presented original data, (2) examined precarious employment within one of the subpopulations of interest, and (3) examined health outcomes. RESULTS: Searches yielded 279 unique results, of which 14 met the eligibility criteria. Of the included studies, 12 studies examined differences between gender, 3 examined the health impacts on young individuals, and 3 examined the health of migrant workers. Mental health was explored in nine studies, general health in four studies, and mortality in two studies. CONCLUSION: Mental health was generally poorer in both male and female employees as a result of precarious employment, and males were also at higher risk of mortality. There was limited evidence that met our inclusion criteria, examining the health impacts on young individuals or migrant workers.

Cardiorespiratory fitness testing and cardiovascular disease risk in male steelworkers.

BACKGROUND: The workplace has been advocated as a setting to perform cardiovascular disease (CVD) risk assessments. These risk assessments usually focus on traditional risk factors rather than cardiorespiratory fitness (CRF) despite established associations between CRF and CVD. The lack of guidance on interpreting health-related CRF values has been suggested as a barrier to utilizing CRF in practice. AIMS: To assess the merits of CRF testing in the workplace and explore whether a CRF value identified male individuals above the recommended threshold for further clinical investigation. METHODS: Cross-sectional analysis of male steelworkers from Carmarthenshire, South Wales, UK who completed a workplace-based CVD risk assessment with an added CRF protocol based on heart rate responses (Chester Step Test). Receiver operating characteristic (ROC) analysis was undertaken to explore the possibility of a CRF value to identify individuals at an increased 10-year risk of CVD (QRISK2 ≥ 10%). RESULTS: There were 81 participants. ROC analysis revealed that a CRF level of 34.5ml/kg/min identified those individuals above the ≥10% QRISK2 threshold with the best sensitivity (0.800) and specificity (0.687) to discriminate against true- and false-positive rates. Further analysis revealed that individuals with either 'Average' or 'Below Average' CRF would be five times more likely to have a 10-year CVD risk above the ≥10% QRISK2 threshold than individuals with an 'Excellent' or 'Good' level of fitness [OR 5.10 (95% CI 1.60-16.3)]. CONCLUSIONS: This study suggests CRF assessments are a useful addition to a workplace CVD assessment and could identify male individuals at increased predicted risk of the condition.

Similar magnitude of post-exercise hyperglycemia despite manipulating resistance exercise intensity in type 1 diabetes individuals.

The aim of this study was to compare the glycemic and glucoregulatory hormone responses to low- and moderate-intensity morning resistance exercise (RE) sessions in type 1 diabetes (T1DM). Following maximal strength assessments (1RM), eight T1DM (HbA1C :72 ± 12 mmol/mol, age:34 ± 7 years, body mass index:25.7 ± 1.6 kg/m(2) ) participants attended the research facility on two separate occasions, having fasted and taken their usual basal insulin but omitting rapid-acting insulin. Participants performed six exercises for two sets of 20 repetitions at 30%1RM during one session [low-intensity RE session (LOW)] and two sets of 10 repetitions at 60%1RM during another session [moderate-intensity RE session (MOD)], followed by 65-min recovery. Sessions were matched for total mass lifted (kg). Venous blood samples were taken before and after exercise. Data (mean ± SEM) were analyzed using analysis of variance (P ≤ 0.05). There were no hypoglycemic occurrences throughout the study. Blood glucose rose similarly between sessions during exercise (P = 0.382), remaining comparable between sessions throughout recovery (P > 0.05). There was no effect of RE intensity on metabolic acidosis (P > 0.05) or peak growth hormone responses (P = 0.644), but a tendency for greater catecholamine responses under LOW (individualized peak concentrations: adrenaline MOD 0.55 ± 0.13 vs LOW 1.04 ± 0.37 nmol/L, P = 0.155; noradrenaline MOD 4.59 ± 0.86 vs LOW 7.11 ± 1.82 nmol/L, P = 0.082). The magnitude of post-exercise hyperglycemia does not differ between equal volume low and moderate intensity RE sessions performed in the morning.

Algorithm that delivers an individualized rapid-acting insulin dose after morning resistance exercise counters post-exercise hyperglycaemia in people with Type 1 diabetes.

AIMS: To develop an algorithm that delivers an individualized dose of rapid-acting insulin after morning resistance exercise to counter post-exercise hyperglycaemia in individuals with Type 1 diabetes. METHODS: Eight people with Type 1 diabetes, aged 34 ± 7 years with HbA1c concentrations 72 ± 12 mmol/mol (8.7 ± 1.1%), attended our laboratory on two separate mornings after fasting, having taken their usual basal insulin the previous evening. These people performed a resistance exercise session comprising six exercises for two sets of 10 repetitions at 60% of the maximum amount of force that was generated in one maximal contraction (60% 1RM). In a randomized and counterbalanced order, the participants were administered an individualized dose of rapid-acting insulin (2 ± 1 units, range 0-4 units) immediately after resistance exercise (insulin session) by means of an algorithm or were not administered this (no-insulin session). Venous blood glucose concentrations were measured for 125 min after resistance exercise. Data (mean ± sem values) were analysed using anova (P ≤ 0.05). RESULTS: Participants had immediate post-resistance exercise hyperglycaemia (insulin session 13.0 ± 1.6 vs. no-insulin session 12.7 ± 1.5 mmol/l; P = 0.834). The decline in blood glucose concentration between peak and 125 min after exercise was greater in the insulin exercise session than in the no-insulin session (3.3 ± 1.0 vs. 1.3 ± 0.4 mmol/l: P = 0.015). There were no episodes of hypoglycaemia (blood glucose <3.9 mmol/l). CONCLUSIONS: Administration of rapid-acting insulin according to an individualized algorithm reduced the hyperglycaemia associated with morning resistance exercise without causing hypoglycaemia in the 2 h post-exercise period in people with Type 1 diabetes.

Impact of single and multiple sets of resistance exercise in type 1 diabetes.

To examine glycemic and glucoregulatory responses to resistance exercise (RE) sessions of different volume in type 1 diabetes (T1DM). Eight T1DM (seven males: one female; age: 38 ± 6 years, HbA1C : 8.7 ± 1.0%/71 ± 11 mmol/mol) attended the research facility fasted and on four separate occasions, having taken their usual basal insulin, but omitted morning rapid-acting insulin. Participants completed a 1SET (14 min), 2SET (28 min), 3SET (42 min) RE session (eight exercises × 10 repetitions) at 67 ± 3% one-repetition-maximum followed by 60-min recovery, or a resting trial (CON). Venous blood samples were taken before and after exercise. Data (mean ± SEM) were analyzed using repeated-measures analysis of variance (P ≤ 0.05). RE did not induce hypoglycemia (BG < 4 mmol/L). During recovery, blood glucose (BG) concentrations remained above pre-exercise after 1SET (15-60 min, P < 0.05) and 2SET (0-60 min, P < 0.05) but comparable (P > 0.05) with pre-exercise after 3SET. BGIAUC(area-under-curve) (mmol/L/60 min) was greater after 1SET and 2SET vs CON (1SET 103.6 ± 36.9 and 2SET 128.7 ± 26.1 vs CON -24.3 ± 15.2, P < 0.05), but similar between 3SET and CON (3SET 40.7 ± 59.3, P > 0.05). Under all trials, plasma creatine kinase levels at 24 h post-exercise were similar (P > 0.05) to pre-exercise. RE does not induce acute hypoglycemia or damage muscle. BG progressively rose after one and two sets of RE. However, inclusion of a third set attenuated exercise-induced hyperglycemia and returned BG to that of a non-exercise trial.

'Prosiect Sir Gâr': workplace-based cardiovascular disease and diabetes risk assessments.

BACKGROUND: Cardiovascular disease (CVD) and diabetes remain two of the greatest health challenges in the UK. Government guidelines recommend screening for both of these conditions to identify individuals at high risk. Assessing individuals in the work environment for these two conditions as part of routine annual medicals could have benefits for both the employee and employer. AIMS: To introduce the Prosiect Sir Gâr workplace-based initiative for CVD and diabetes prevention and report some of the baseline measurements in regards to CVD and diabetes risk. METHODS: Individuals from two workplaces (local health board and steelworks) attended a medical health check with an added CVD and diabetes risk assessment component. Demographic and anthropometric data, systolic and diastolic blood pressure, smoking status and family and medical histories were recorded. Blood samples were analysed for total and high-density lipoprotein cholesterol and HbA1c. Ten year risk of CVD and diabetes were predicted using the QRISK2 and QDiabetes algorithms. Individuals at high risk of either condition were referred to a lifestyle intervention programme. RESULTS: Among over 800 individuals screened a high prevalence of central obesity (75%), systolic hypertension (20%) and diastolic hypertension (23%) were observed in both workforces. In addition, a substantial proportion of the workers were either 'overweight' (42%) or 'obese' (28%). CONCLUSIONS: Introducing CVD and diabetes risk assessments to routine annual medicals in the workplace uncovered significant isolated risk factors for both CVD and diabetes that may otherwise have remained undiagnosed. This approach also gave employers a more detailed awareness of the current health of their employees.

Reductions in resistance exercise-induced hyperglycaemic episodes are associated with circulating interleukin-6 in type 1 diabetes.

AIMS: To determine the influence of different volumes of resistance exercise on circulating interleukin-6 (IL-6) and to explore the relationships between IL-6 and glycaemia. METHODS: Eight participants with complication-free type 1 diabetes, whose mean ± SEM age was 38 (6) years, mean ± SEM HbA(1c) concentration was 71 ±11 mmol/mol (8.7 ±1.0%) and mean ± SEM type 1 diabetes duration was 15 ±13 years, attended the research facility after an overnight fast on four separate occasions, having administered their basal insulin the night before (glargine 27.5±3.1U, n=8), but omitted morning rapid-acting insulin. Participants completed either a one-set (14-min), two-set (28-min), or three-set (42-min) resistance exercise trial (eight exercises × 10 repetitions) at 67±3% one-repetition maximum followed by a 60-min recovery, or a resting control trial. Venous blood samples were taken before and after exercise. Data were analysed using repeated-measures ANOVA (P≤0.05). RESULTS: Whereas IL-6 levels remained similar to baseline levels after one set of resistance exercises (30 min, P=0.287; 60 min, P=0.318), IL-6 levels were > baseline levels at 60 min post-exercise after a two-set exercise trial (2.94 ± 0.94 pg/ml, P=0.002) and doubled at both 30 min (4.01 ± 1.00 pg/ml, P=0.048) and 60 min (4.28 ± 1.25 pg/ml, P=0.084) post-exercise after the three-set resistance exercise trial. Post-exercise blood glucose area under the curve (mmol/l/60 min) was greater after both the one-set (P=0.025) and two-set trials (P=0.008), than after the control trial, but similar between the three-set trial and the control trial (P=0.240). The rise in IL-6 from baseline to peak concentration significantly correlated inversely with blood glucose area under the curve (r=-0.65, P=0.041). CONCLUSIONS: Circulating IL-6 is increased by resistance exercise in a volume-dependent manner, and resistance exercise-induced increases in IL-6 correlated with reductions in post-exercise hyperglycaemia in type 1 diabetes, suggesting a role for IL-6 in improving post-resistance exercise glycaemic disturbances in type 1 diabetes.

Cough threshold to citric acid in diabetic patients with and without autonomic neuropathy.

The cough reflex has been investigated in insulin dependent diabetic patients with and without autonomic neuropathy. The cough response to inhaled citric acid was determined in eight patients with diabetes who had severe autonomic neuropathy and compared with that in 10 who had no evidence of neuropathy. The patients with autonomic neuropathy had a higher median threshold for the cough response to citric acid (median 50%, range 20- greater than 100%) than non-neuropathic control patients (median 10%, range 2-20%). These results suggest that vagal innervation of the bronchial tree is damaged by diabetic autonomic neuropathy.

Transcutaneous oxygen tension during exercise in patients with pulmonary emphysema.

Transcutaneous PO2 (tcPO2) and arterial PO2 (PaO2) were compared during exercise in six patients with pulmonary emphysema. For calibration purposes, the tcPO2 electrode was first attached to the skin and after stabilisation its reading was adjusted to correspond to the PO2 of an initial arterial blood sample. It was shown that tcPO2 measurement could follow accurately the rapid changes in PaO2 occurring during exercise. Sixty-eight paired comparisons of PaO2 and tcPO2 were available and the regression equation was given by: tcPO2 (mmHg) = 0.98 PaO2 + 0.7 (correlation coefficient, 0.985; 95% confidence limits, 5.7 mmHg).

In vivo calibration of a transcutaneous oxygen electrode in adult patients.

Transcutaneous oxygen tension (tcPO2) has been compared with arterial oxygen tension (PaO2 in 14 haemodynamically stable patients in an intensive care unit. Two calibration methods have been compared: (1) "In vitro" calibration, a two point calibration procedure carried out before attachment to the skin. (2) "In vivo" calibration, calibration using a single arterial sample, to recalibrate the upper point after attachment of the electrode to the skin and stabilisation of the electrical output. After "in vitro" calibration the regression equation was given by tcPO2 (mmHg) = 0.58 PaO2 + 13.4 (95% confidence limits +/- 19.6). After "in vivo" calibration, the regression equation for 55 comparisons over the range 50 to 120 mmHg was given by: tcPO2 (mmHg) = 0.98 PaO2 + 1.6 (95% confidence limits +/- 6.6). The "in vivo" calibration method therefore allows a close estimate of PaO2 to be made from tcPO2 values in adult patients providing strict operating criteria observed.

Assessing effective obturation.

The use of lung function tests and sequential radiography appear to be suitable complementary methods of contrasting the effectiveness of obturator prostheses provided in the management of maxillectomy patients. The creation of an oral seal, demonstrable by normal subjects during swallowing and in the production of certain speech sounds, appears to be unobtainable in the management of maxillectomy. Effective obturation produces sufficient separation of the oral cavity from the nasal cavity to permit efficient swallowing and intelligible speech. These two methods also offer simple means to evaluate subjective experiences of the patient.

Effect of rifampicin administration on theophylline pharmacokinetics in humans.

Theophylline pharmacokinetics were studied before and after rifampicin administration (600 mg daily for 1 wk). Rifampicin reduced the area under the concentration-time curve by 18% after the oral administration of sustained release aminophylline (450 mg) to 7 normal subjects (p less than 0.05) and increased the metabolic clearance and volume of distribution by 45% (p less than 0.05) and 17% (p less than 0.05), respectively, after the intravenous administration of aminophylline (5 mg/kg over 30 min) to 8 normal subjects. These findings are consistent with an inducing and choleretic effect of rifampicin on theophylline disposition. In patients receiving theophylline, blood levels should be monitored closely and dosage adjusted if rifampicin therapy is introduced or withdrawn.

Stepfamilies: a concern health education should address.

In this country there are more than 1 million children who find themselves in a stepfamily situation. Coping with the changes involved can be a difficult process. Health educators need to recognize the fact that many children are in this situation. Through the subunits included in the family life unit, young people can be taught how to deal with the issues involved. In so doing, health education will be addressing another major family life problem in our society.

Diminished bronchial reactivity to cold air in diabetic patients with autonomic neuropathy.

To investigate the role of neural pathways in the nonasthmatic response to eucapnic hyperventilation with below freezing air five diabetic patients with severe symptomatic autonomic neuropathy were studied. Their responses were compared with those shown by five diabetic patients without autonomic neuropathy and five non-diabetic controls. After bronchial provocation testing with cold air the diabetic patients with autonomic neuropathy did not show a significant fall in specific airways conductance (mean (SE) maximum percentage fall 2.0 (3)%), whereas conductance fell in the diabetic patients without neuropathy by 30.8 (2.0)% (p less than 0.001) and in the non-diabetic controls by 22.7 (4.6)% (p less than 0.02). In subjects who do not have asthma the bronchial response to cold air is mediated largely via neural mechanisms.
