Non-pharmacologic treatment of insomnia in primary care settings

Adopting STOPP/START Criteria Version 3 in Clinical Practice: A Q&A Guide for Healthcare Professionals

The growing complexity of geriatric pharmacotherapy necessitates effective tools for mitigating the risks associated with polypharmacy. The Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (STOPP)/Screening Tool to Alert doctors to Right Treatment (START) criteria have been instrumental in optimizing medication management among older adults. Despite their large adoption for improving the reduction of potentially inappropriate medications (PIM) and patient outcomes, the implementation of STOPP/START criteria faces notable challenges. The extensive number of criteria in the latest version and time constraints in primary care pose practical difficulties, particularly in settings with a high number of older patients. This paper critically evaluates the challenges and evolving implications of applying the third version of the STOPP/START criteria across various clinical settings, focusing on the European healthcare context. Utilizing a "Questions & Answers" format, it examines the criteria's implementation and discusses relevant suitability and potential adaptations to address the diverse needs of different clinical environments. By emphasizing these aspects, this paper aims to contribute to the ongoing discourse on enhancing medication safety and efficacy in the geriatric population, and to promote more person-centred care in an aging society.

Effects of insomnia treatments on cognitive function: A meta-analysis of randomized controlled trials

BACKGROUND

Globally, insomnia has been shown to impact cognitive function, which has prompted the exploration of effective treatments to enhance cognitive outcomes. Both pharmacological and non-pharmacological interventions vary in their effects, indicating that further research for optimized therapeutic strategies is needed.

METHODS

Searches of PubMed, EMBASE, Web of Science, the Cochrane Library, and PsychInfo from database inception until August 2024 were conducted to identify relevant randomized controlled studies investigating the impacts of insomnia treatments on cognitive function. The standardized mean difference (SMD) and 95% confidence interval (CI) were calculated for all studies. Sensitivity analysis, publication bias, and meta-regression were performed.

RESULTS

A total of 14,829 records were retrieved, with 24 randomized controlled studies assessing the impact of insomnia treatment on cognition. Pooled analysis indicated that non-pharmacological interventions significantly enhanced cognitive function (SMD: 0.27, 95% CI: 0.04-0.49, p = 0.019), with notable improvements observed in memory (SMD: 1.18, 95% CI: 0.25-2.12, p = 0.013), attention (SMD: 0.32, 95% CI: 0.15-0.50, p < 0.001), and daily living activities (SMD: 0.29, 95% CI: 0.20-0.39, p < 0.001) based on self-reported measures. Longer follow-up periods were associated with more pronounced cognitive benefits (SMD: 0.34, 95% CI: 0.14-0.54, p = 0.001).

CONCLUSIONS

The critical role of insomnia treatments, particularly non-pharmacological interventions, in improving cognitive function is highlighted, emphasizing the importance of tailored therapeutic approaches to optimize cognitive outcomes and overall well-being.

Consumption patterns and factors associated with inappropriate prescribing of benzodiazepines in Primary Health Care settings

BACKGROUND

Benzodiazepines are frequently prescribed to treat anxiety and insomnia, but long-term use has been associated with the development of dependence, tolerance, and cognitive decline, especially among older adults. This study aimed to investigate the pattern of consumption and factors associated with inappropriate prescribing of benzodiazepines in primary health care.

METHODS

This is a cross-sectional analytical study, using dispensing records of diazepam, clonazepam, and nitrazepam from public pharmacies in a Brazilian municipality between 2018 and 2022. Metrics for benzodiazepine consumption were DDD (Defined Daily Dose) and DDD/1000PD (per 1000 population per day). Long-term/prolonged benzodiazepine use was defined as consuming at least 90 DDD and at least 2 dispensations per year. To ascertain associations between long-term use and predictor variables, a multivariate logistic regression model was utilized.

FINDINGS

A total of 40402 participants were included, with an average age of 55 years (SD = 0.30), 38.5% were older aged. Diazepam and nitrazepam exceeded the daily dose recommended. There was a reduction in diazepam consumption during the study period, as calculated by DDD/1.000PD, while the consumption of other benzodiazepines remained stable. However, a significant increase in diazepam consumption is noted when considering the last decade. Prolonged use was observed in 29.1% of participants, with a significant prevalence among the older people (34.8% of them were long-term users) and advancing age was identified as a risk factor for long-term use. Higher PDDs were also associated with long-term use and aging. Participants who used different benzodiazepines during the period had a higher risk of prolonged use.

CONCLUSIONS

These results provide insights into the prevalence of problematic utilization of benzodiazepines in primary health care. Authorities and health care providers must take steps to encourage gradual cessation of prolonged benzodiazepine prescriptions and the embrace of suitable strategies for addressing anxiety and insomnia within primary health care settings.

Cubital tunnel syndrome: anatomy, pathology, and imaging

Cubital tunnel syndrome (CuTS) is the second most common peripheral neuropathy in the upper limb. It occurs due to ulnar nerve compression within the fibro-osseous cubital tunnel at the elbow joint. Although CuTS is typically diagnosed clinically and with electrodiagnostic studies, the importance of imaging in evaluating the condition is growing. Knowing the typical imaging findings of ulnar nerve entrapment is necessary for precise diagnosis and proper treatment. In this article, we focus on the clinical features, workup and complex imaging of the "anatomic" cubital tunnel and relevant pathological entities.

Sleep disorders in chronic pain and its neurochemical mechanisms: a narrative review

Chronic pain (CP) is a prevalent problem, and more than half of patients with CP have sleep disorders. CP comorbidity with sleep disorders imposes immense suffering and seriously affects the patient's quality of life, which is a challenging issue encountered by clinicians. Although the reciprocal interactions between pain and sleep have been studied to some degree, there is still a lack of awareness and comprehensive description of CP comorbidity with sleep disorders. In this narrative review article, we summarize the current knowledge about the present estimates of the prevalence of comorbid sleep disorders in CP patients, sleep detection methods, sleep characterization in CP, and the effect of sleep disorders on CP and current therapies. We also summarize current knowledge of the neurochemical mechanisms of CP comorbidity with sleep disorders. In conclusion, insufficient attention has been paid to the role of sleep disorders in CP patients, and CP patients should be screened for sleep disorders in the clinic. Special attention should be given to a possible risk of drug-drug interaction when using two types of drugs targeting pain and sleep simultaneously. The current insight into the neurobiological mechanisms underlying CP comorbidity with sleep disorders is still rather limited.

High prevalence of insomnia among physiatrists in the Czech Republic: A web-based questionnaire survey

BACKGROUND

Physicians who suffer from poor sleep quality are at an increased risk of mistakes and poor decision-making. We deemed it noteworthy to assess sleep quality in practicing physiatrists, previously reported to be at higher risk of physician burnout, which was documented associated with sleep deprivation.

OBJECTIVE

The aim was to estimate the prevalence of sleep disturbance among practicing physiatrists and evaluate the association of sleep quality with their sleep hygiene habits and depression.

METHODS

Of the 101 study participants (77 females) who met the inclusion criteria, the majority was between the age of 25 and 40 years (70.3% ); 62 (61.4% ) were specialists and 39 (38.6% ) were in training. In this cross-sectional study, practicing physiatrists were invited to complete an anonymous and voluntary web-based survey. The survey consisted of questions covering demographic information, nicotine and caffeine consumption, exercise habits, and three questionnaires: the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory-II (BDI-II), and the Sleep Hygiene Index (SHI).

RESULTS

Sixty-five (64.4% ) respondents showed poor sleep quality (PSQI >  5), and 23 (22.8% ) showed at least mild symptoms of depression (BDI-II>13). The mean PSQI, SHI, BDI-II scores were 6.85±3.09, 18.18±5.35, and 8.36±7.52, respectively. Poor sleep quality was significantly positively correlated with symptoms of depression and sleep hygiene misbehavior.

CONCLUSION

We found that 64.4% of practicing physiatrists suffered from poor sleep quality, and 22.8% showed at least mild symptoms of depression. Considerable efforts should be directed toward sleep hygiene behavior and mental health improvement.

Evaluation of an occupation-based sleep program for people with Insomnia

Background

Sleep problems are a health issue worldwide. Based on the Person-Environment-Occupation-Performance model, we developed an occupation-based sleep programme to promote awareness of sleep hygiene factors, promote an environment conductive to sleep, and restructure participation in daytime activities with a focus on occupational balance.

Method

This study uses a non-equivalent group design to evaluate the effectiveness of an occupation-based sleep intervention among community-dwelling adults with insomnia, when compared with a treatment-as-usual (TAU) group which focused on sleep hygiene, and relaxation.

Results

When compared with the TAU group ( n = 20), the intervention group ( n = 22) had significant improvement in sleep duration, occupational balance, and reduction in mood symptoms at both post treatment and 1-month follow up.

Conclusion

The results demonstrated that an occupation-based programme is an effective treatment for insomnia disorder and demonstrated the role which occupational therapy could play in primary health care service.

Improved Functional Organization in Patients With Primary Insomnia After Individually-Targeted Transcranial Magnetic Stimulation

Primary insomnia (PI) is among the most prevalent sleep-related disorders and has a far-reaching impact on daytime functioning. Repetitive transcranial magnetic stimulation (rTMS) has drawn attention because of its effectiveness and safety. The purpose of the current study was to detect changes in the topological organization of whole-brain functional networks and to determine their associations with the clinical treatment effects of rTMS. Resting-state functional magnetic resonance imaging (rsfMRI) data from 32 patients with PI were collected and compared with findings from 32 age- and gender-matched healthy controls (HCs). The patients were treated with Stanford accelerated intelligent neuromodulation therapy, which is a recently validated neuroscience-informed accelerated intermittent theta-burst stimulation protocol. Graph theoretical analysis was used to construct functional connectivity matrices and to extract the attribute features of small-world networks in insomnia. Scores on the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index, Self-Rating Anxiety Scale, Self-Rating Depression Scale, and the associations between these clinical characteristics and functional metrics, were the primary outcomes. At baseline, the patients with PI showed inefficient small-world property and aberrant functional segregation and functional integration compared with the HCs. These properties showed renormalization after individualized rTMS treatment. Furthermore, low functional connectivity between the right insula and left medial frontal gyrus correlated with improvement in ISI scores. We highlight functional network dysfunctions in PI patients and provide evidence into the pathophysiological mechanisms involved and the possible mode of action of rTMS.

Effect of Ashwagandha (Withania somnifera) extract on sleep: A systematic review and meta-analysis

OBJECTIVE

To determine the effect of Ashwagandha extract on sleep.

METHODS

A comprehensive search was conducted in CENTRAL, MEDLINE, SCOPUS, Google Scholars, World Health Organization Trials Portal, ClinicalTrials.gov, Clinical Trial Registry of India, and AYUSH Research Portal for all appropriate trials. Randomized controlled trials that examined the effect of Ashwagandha extract versus placebo on sleep in human participants 18 years old and above were considered. Two authors independently read all trials and independently extracted all relevant data. The primary outcomes were sleep quantity and sleep quality. The secondary outcomes were mental alertness on rising, anxiety level, and quality of life.

RESULTS

A total of five randomized controlled trials containing 400 participants were analyzed. Ashwagandha extract exhibited a small but significant effect on overall sleep (Standardized Mean Difference -0.59; 95% Confidence Interval -0.75 to -0.42; I2 =  62%). The effects on sleep were more prominent in the subgroup of adults diagnosed with insomnia, treatment dosage ≥600 mg/day, and treatment duration ≥8 weeks. Ashwagandha extract was also found to improve mental alertness on rising and anxiety level, but no significant effect on quality of life. No serious side effects were reported.

CONCLUSION

Ashwagandha extract appears to has a beneficial effect in improving sleep in adults. However, data on the serious adverse effects of Ashwagandha extract are limited, and more safety data would be needed to assess whether it would be safe for long-term use.

Ulnar Neuropathy at the Elbow: From Ultrasound Scanning to Treatment

Ulnar neuropathy at the elbow (UNE) is commonly encountered in clinical practice. It results from either static or dynamic compression of the ulnar nerve. While the retroepicondylar groove and its surrounding structures are quite superficial, the use of ultrasound (US) imaging is associated with the following advantages: (1) an excellent spatial resolution allows a detailed morphological assessment of the ulnar nerve and adjacent structures, (2) dynamic imaging represents the gold standard for assessing the ulnar nerve stability in the retroepicondylar groove during flexion/extension, and (3) US guidance bears the capability of increasing the accuracy and safety of injections. This review aims to illustrate the ulnar nerve's detailed anatomy at the elbow using cadaveric images to understand better both static and dynamic imaging of the ulnar nerve around the elbow. Pathologies covering ulnar nerve instability, idiopathic cubital tunnel syndrome, space-occupying lesions (e.g., ganglion, heterotopic ossification, aberrant veins, and anconeus epitrochlearis muscle) are presented. Additionally, the authors also exemplify the scientific evidence from the literature supporting the proposition that US guidance is beneficial in injection therapy of UNE. The non-surgical management description covers activity modifications, splinting, neuromobilization/gliding exercise, and physical agents. In the operative treatment description, an emphasis is put on two commonly used approaches-in situ decompression and anterior transpositions.
