Sodium-glucose cotransporter-2 inhibitors reduce cardiovascular outcomes in patients with congestive heart failure and a biventricular circulation. Congestive heart failure in Fontan univentricular circulation is distinctly different. Experience with sodium-glucose cotransporter-2 inhibitors in this group has not yet been well described.

This work describes safety and tolerability of sodium-glucose cotransporter-2 inhibitors in patients with Fontan circulation.

Single-centre review of patients with Fontan circulation prescribed a sodium-glucose cotransporter-2 inhibitors for congestive heart failure. Primary outcome was tolerability or need for discontinuation. Secondary outcomes were changes in New York Heart Association class, congestive heart failure hospitalisation, ventricular function, exercise performance, and laboratory values.

We identified 25 patients with Fontan circulation prescribed an sodium-glucose cotransporter-2 inhibitors, most with a systemic right ventricle. Over a third of subjects had at least moderately reduced baseline ventricular function. Baseline catheterisation showed a mean Fontan pressure of 17.1 ± 3.7 mmHg and pulmonary capillary wedge pressure 11.7 ± 3.2 mmHg at rest; 59% had occult diastolic dysfunction with abnormal pulmonary capillary wedge pressure elevation following volume expansion. Most were on congestive heart failure medications and/or a pulmonary vasodilator prior to sodium-glucose cotransporter-2 inhibitors addition, and three had a congestive heart failure hospitalisation within the previous year. All reported good medication tolerance except one patient was nonadherent to medications and two discontinued sodium-glucose cotransporter-2 inhibitors for perceived side effects. There were no significant differences in secondary outcomes. There was, however, a downward trend of serum brain natriuretic peptide (n = 13) and improved peak VO2 (n = 6), though neither statistically significant (p > 0.05).

This series, the largest published to date, suggests that sodium-glucose cotransporter-2 inhibitors are safe and tolerable congestive heart failure therapy in Fontan circulation. Further research is warranted to explore therapy in this unique population.

The Portsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (‘P-POSSUM’) is a two-part scoring system that includes a physiological assessment and a measure of operative severity. This study sought to determine whether risk estimates for this scoring system could be used in major head and neck reconstructive surgery.

A retrospective review was performed of patients undergoing resection for a temporal bone malignancy in a single head and neck centre in Dublin, Ireland, from 2002 to 2021.

The mean ± standard deviation morbidity estimate calculated using the scoring system was 47.6 per cent ± 19.5 per cent. The actual rate of complications was 47 per cent. The optimal cut-off for the scoring system was calculated using the Youden index from the receiver operating characteristic curve, which was 40.5 per cent in this case.

The study indicates that the Portsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity is a useful tool for predicting morbidity risk in patients undergoing head and neck resection with reconstruction for temporal bone malignancies.

To identify the impact of universal masking on COVID-19 incidence and putative SARS-CoV-2 transmissions events among children’s hospital healthcare workers (HCWs).

Quasi-experimental study.

Single academic free-standing children’s hospital.

We performed whole-genome sequencing of SARS-CoV-2- PCR-positive samples collected from HCWs 3 weeks before and 6 weeks after implementing a universal masking policy. Phylogenetic analyses were performed to identify clusters of clonally related SARS-CoV-2 indicative of putative transmission events. We measured COVID-19 incidence, SARS-CoV-2 test positivity rates, and frequency of putative transmission events before and after the masking policy was implemented.

HCW COVID-19 incidence and test positivity declined from 14.3 to 4.3 cases per week, and from 18.4% to 9.0%, respectively. Putative transmission events were only identified prior to universal masking.

A universal masking policy was associated with reductions in HCW COVID-19 infections and occupational acquisition of SARS-CoV-2.

Registry-based trials have emerged as a potentially cost-saving study methodology. Early estimates of cost savings, however, conflated the benefits associated with registry utilisation and those associated with other aspects of pragmatic trial designs, which might not all be as broadly applicable. In this study, we sought to build a practical tool that investigators could use across disciplines to estimate the ranges of potential cost differences associated with implementing registry-based trials versus standard clinical trials.

We built simulation Markov models to compare unique costs associated with data acquisition, cleaning, and linkage under a registry-based trial design versus a standard clinical trial. We conducted one-way, two-way, and probabilistic sensitivity analyses, varying study characteristics over broad ranges, to determine thresholds at which investigators might optimally select each trial design.

Registry-based trials were more cost effective than standard clinical trials 98.6% of the time. Data-related cost savings ranged from $4300 to $600,000 with variation in study characteristics. Cost differences were most reactive to the number of patients in a study, the number of data elements per patient available in a registry, and the speed with which research coordinators could manually abstract data. Registry incorporation resulted in cost savings when as few as 3768 independent data elements were available and when manual data abstraction took as little as 3.4 seconds per data field.

Registries offer important resources for investigators. When available, their broad incorporation may help the scientific community reduce the costs of clinical investigation. We offer here a practical tool for investigators to assess potential costs savings.

To characterize adults with comorbid attention-deficit/hyperactivity-disorder (ADHD) and borderline personality disorder (BPD) with regard to ADHD symptoms, psychopathology, cognitive functioning and psychosocial factors.

A between-group design compared a group of individuals diagnosed with ADHD (n = 40) with a group diagnosed with BPD and who also met the criteria for ADHD (ADHD + BPD) (n = 20).

Significant differences were observed for both childhood and current impulsivity symptoms, whereby ADHD + BPD exhibited increased impulsivity; no differences on self-report and cognitive measures of impulsivity were reported. The ADHD + BPD group scored significantly higher on measures of depression, anxiety and numerous other axis I and II conditions. The ADHD + BPD group scored significantly lower on most measures of intellectual functioning and attention, however largely not on those relating to response inhibition. Furthermore, group differences were observed for psychosocial factors, including education, substance use and criminal record.

Comorbid ADHD and BPD is characterized by more symptoms of impulsivity, additional psychopathology, comparatively lower intellectual and attentional functioning and increased psychosocial difficulties.

To describe public health nurses’ (PHN) experiences of referring to, and families’ experiences of being referred to, a multicomponent, community-based, childhood weight management programme and to provide insight into families’ motivation to participate in and complete treatment.

Qualitative study using semi-structured interviews and the draw-and-write technique.

Two geographical regions in the south and west of Ireland.

Nine PHN involved in the referral process, as well as ten parents and nine children who were referred to and completed the programme, participated in the present study.

PHN were afraid of misclassifying children as obese and of approaching the subject of excess weight with parents. Peer support from other PHN as well as training in how best to talk about weight with parents were potential strategies suggested to alleviate these fears. Parents recalled the anxiety provoked by the ‘medical terminology’ used during referral and their difficulty interpreting what it meant for the health of their child. Despite initial fears, concern for their children’s future health was a major driver behind their participation. Children’s enjoyment, the social support experienced by parents as well as staff enthusiasm were key to programme completion.

The present study identifies the difficulties of referring families to community weight management programmes and provides practical suggestions on how to support practitioners in making referrals. It also identifies key positive factors influencing parents’ decisions to enrol in community weight management programmes. These should be maximised by staff and policy makers when developing similar programmes.

Families of children born with CHD face added stress owing to uncertainty about the magnitude of the financial burden for medical costs they will face. This study seeks to assess the family responsibility for healthcare bills during the first 12 months of life for commercially insured children undergoing surgery for severe CHD.

The MarketScan® database from Truven was used to identify commercially insured infants in 39 states from 2010 to 2012 with an ICD-9 diagnosis code for transposition of the great arteries, tetralogy of Fallot, or truncus arteriosus, as well as the corresponding procedure code for complete repair. Data extraction identified payment responsibilities of the patients’ families in the form of co-payments, deductibles, and co-insurance during the 1st year of life.

There were 481 infants identified who met the criteria. Average family responsibility for healthcare bills during the 1st year of life was $2928, with no difference between the three groups. The range of out-of-pocket costs was $50–$18,167. Initial hospitalisation and outpatient care accounted for the majority of these responsibilities.

Families of commercially insured children with severe CHD requiring corrective surgery face an average of ~$3000 in out-of-pocket costs for healthcare bills during the first 12 months of their child’s life, although the amount varied considerably. This information provides a framework to alleviate some of the uncertainty surrounding healthcare financial responsibilities, and further examination of the origination of these expenditures may be useful in informing future healthcare policy discussion.

Cannabis use shows a robust dose-dependent relationship with psychosis risk among the general population. Despite this, it has been difficult to link cannabis use with risk for transitioning to a psychotic disorder among individuals at ultra-high risk (UHR) for psychosis. The present study examined UHR transition risk as a function of cannabis use characteristics which vary substantially between individuals including age of first use, cannabis abuse severity and a history of cannabis-induced attenuated psychotic symptoms (APS).

Participants were 190 UHR individuals (76 males) recruited at entry to treatment between 2000 and 2006. They completed a comprehensive baseline assessment including a survey of cannabis use characteristics during the period of heaviest use. Outcome was transition to a psychotic disorder, with mean time to follow-up of 5.0 years (range 2.4–8.7 years).

A history of cannabis abuse was reported in 58% of the sample. Of these, 26% reported a history of cannabis-induced APS. These individuals were 4.90 (95% confidence interval 1.93–12.44) times more likely to transition to a psychotic disorder (p = 0.001). Greater severity of cannabis abuse also predicted transition to psychosis (p = 0.036). However, this effect was mediated by higher abuse severity among individuals with a history of cannabis-induced APS.

Findings suggest that cannabis use poses risk in a subpopulation of UHR individuals who manifest cannabis-induced APS. Whether this reflects underlying genetic vulnerability requires further study. Nevertheless, findings reveal an important early marker of risk with potentially significant prognostic utility for UHR individuals.

Peer volunteers can be key to delivering effective social cognitive interventions due to increased potential for social modeling. We consulted peer volunteers who had just taken part in an 8-week social and nutritional mealtime intervention with older adults living alone, to seek their evaluation of the intervention.

Semi-structured focus groups were used with a total of 21 volunteers (17 female) and two facilitators. Thematic analysis was used to interrogate the data.

Six themes (16 sub-themes) are discussed. Peer volunteers described the importance of the socializing aspect of the intervention, of pairing considerations and compatibility in peer interventions, of considering the needs of the participant, of benefits to the volunteers, and of the practical considerations of conducting an intervention. Volunteers also discussed considerations for future research and services for older adults living alone.

Volunteers found their involvement in the intervention to be personally beneficial, and revealed some valuable considerations for the researchers to take forward to future research. Results are pertinent to intervention design and could inform future social cognitive and other peer-oriented interventions for older adults living alone.

Physical health and, in particular, frailty may be associated with psychological factors among older adults. We aimed to investigate the relationships between aspects of psychological distress and progression of frailty over time among older adults.

We used a longitudinal observational study design with 624 participants aged over 60 years (mean age=72.75, s.d.=7.21, 68% female) completing a baseline comprehensive biopsychosocial geriatric assessment, and 447 returning for a follow-up assessment 2 years later. Aspects of psychological distress, physical health, and frailty were analysed for the purposes of this study. We employed a series of logistic regression analyses to determine psychological predictors of changing states of aspects of frailty over time.

With individual components of frailty, neuroticism and age predicted negative transitions of exhaustion and grip strength, respectively, whereas age alone was a predictor of transitions in overall frailty scores based on four components.

We conclude that neuroticism and age may impact upon physical frailty and its progression over time in an ageing population. These findings may reflect the tendency for those with high levels of neuroticism to endorse negative symptoms, or alternatively, neuroticism may result in exhaustion via worry in an older population. Further research is required to further elucidate this relationship.

It is widely accepted that people with mental illness have increased risk of cardiometabolic complications such as obesity and type 2 diabetes mellitus. What is less well known is that individuals with diabetes have an increased risk of brain health complications including depression, cognitive impairment and dementia. These conditions can adversely influence disease self-management and further increase risk of other diabetes complications.

The aim of this paper is to highlight the increased risk of brain health complications in populations with diabetes in order to promote awareness of such complications among healthcare professionals and encourage timely intervention.

An overview of the prevalence and potential mechanisms linking depression and cognitive impairment with diabetes as well as implications for detection, management and brain health protection, based on a narrative review of the literature.

Early detection and effective management of depression and cognitive impairment among individuals with diabetes has the potential to minimise adverse health outcomes. In order to promote screening healthcare professionals caring for individuals with diabetes in all settings must be aware of the increased risk of brain health complications in this vulnerable population.
