Drahman A, Ngee-Soon SL, Crawford M. Prophylactic alpha-blockade for prevention of post-operative urinary retention after inguinal hernia repair: a systematic review and meta-analysis. Hernia 2023; 27:1351-1361. [PMID: 36952050 DOI: 10.1007/s10029-023-02764-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 03/02/2023] [Indexed: 03/24/2023]
Abstract
BACKGROUND The rate of post-operative urinary retention (POUR) in inguinal hernia repairs (IHR) is estimated to be approximately 5.9% to 38% worldwide. Currently, there are minimal studies on the prophylaxis of POUR after IHR. Pre-operative administration of alpha-blockers such as (but not limited to) Tamsulosin, Prazosin and Alfuzosin has shown promising results in the prevention of POUR in patients undergoing IHR. This study aims to determine the effectiveness of prophylactic alpha-blockade in the prevention of POUR after IHR. METHODS This study reports the findings of a systematic review and meta-analysis. Randomised controlled trials (RCTs) using prophylactic alpha-blockade for the prevention of POUR after open and/or laparoscopic IHR in patients aged more than 18 years in all sex groups were included. Multiple databases were searched from inception to October 2021 using the PRISMA flow diagram. Data were extracted and analysed to include eligibility criteria, comparator, intervention, study and participant characteristics. Studies excluded were non-RCT studies and patients with known urinary tract disorders such as benign prostate hypertrophy, urinary incontinence and cancer of the bladder or prostate. Subgroup analyses were also conducted. All effect measures of each data were odds ratio with 95% confidence interval. All studies were pooled using the dichotomous random effects Mantel-Haenszel statistical mode and I2 was used to assess heterogeneity. Publication bias was detected using the Cochrane risk-of-bias tool for randomised trials (RoB-2) involving two independent reviewers. RESULTS A total of eight RCTs were identified which provided adequate numeric data for incorporation into the meta-analysis. Overall, administration of pre-operative alpha-blocker prior to IHR did not prevent POUR (95% CI 1.20 (0.96-1.49), I2: 34%). Subgroup analysis comparing pre-operative use of prophylactic alpha-blocker in open versus laparoscopic IHR has shown statistically significant reduction of POUR prevention in the laparoscopic group (95% CI 0.66 (0.47-0.92)), I2: 43%). The older age group benefited from pre-operative alpha-blocker use with reduced incidence of POUR post-IHR (95% CI 0.14 (0.08, 0.23), I2: 0%)). Gender did not affect the difference of incidence of POUR post-IHR despite pre-operative alpha-blockers (95% CI 0.62 (0.27, 1.44)), I2: 53%)). CONCLUSION Overall, this meta-analysis has shown that administration of prophylactic alpha-blockers did not prevent POUR. However, there was statistically significant reduction of POUR in patients undergoing laparoscopic IHR as compared to open, as well as in older patients (age more than 60 years) after administration of pre-operative alpha-blocker. Hence, the use of pre-operative alpha-blocker especially in older patients should be considered and more RCTs should be undertaken.

Abstract
BACKGROUND AND PURPOSE To better understand the effects of an intervention, Mindfulness for Healthcare Professional (MIHP), and how it may improve healthcare professional student (HCP) functioning, a constructivist grounded theory exploration was conducted. MATERIALS AND METHODS Ten participants with the lowest or highest changes on quantitative measures of burnout and perceived stress at the end of MIHP were interviewed at a long-term follow-up. A theoretical framework was developed from the resultant themes to describe the mechanisms by which MIHP had effects on work-relevant functioning. RESULTS Three overarching themes emerged as mechanisms of change both from their presence in those participants reporting an improvement in stress and their missingness from those participants who reported no change: developing a mindfulness practice, integrating practice into daily life, and enhanced awareness. These mechanisms led to optimized work-relevant functioning: 1) emotional competencies, including nonjudgement, emotion regulation, and burnout prevention; and 2) patient-centered care, including improved listening, patience, and efficiency at work. CONCLUSION The resultant framework is discussed in the context of previous literature on MIHP and mindfulness theory more broadly. Implications for future disseminations of MIHP encourage the use of group interventions with emphasis on developing at-home practice and informal mindfulness integrated into daily work.

Abstract
BACKGROUND Many patients with bi-lobar liver tumours are not eligible for liver resection due to an insufficient future liver remnant (FLR). To reduce the risk of posthepatectomy liver failure and the primary cause of death, regenerative procedures intent to increase the FLR before surgery. The aim of this systematic review is to provide an overview of the available literature and outcomes on the effectiveness of simultaneous portal and hepatic vein embolization (PVE/HVE) versus portal vein embolization (PVE) alone. METHODS A systematic literature search was conducted in PubMed, Web of Science, and Embase up to September 2022. The primary outcome was resectability and the secondary outcome was the FLR volume increase. RESULTS Eight studies comparing PVE/HVE with PVE and six retrospective PVE/HVE case series were included. Pooled resectability within the comparative studies was 75 per cent in the PVE group (n = 252) versus 87 per cent in the PVE/HVE group (n = 166, OR 1.92 (95% c.i., 1.13-3.25)) favouring PVE/HVE (P = 0.015). After PVE, FLR hypertrophy between 12 per cent and 48 per cent (after a median of 21-30 days) was observed, whereas growth between 36 per cent and 67 per cent was reported after PVE/HVE (after a median of 17-31 days). In the comparative studies, 90-day primary cause of death was similar between groups (2.5 per cent after PVE versus 2.2 per cent after PVE/HVE), but a higher 90-day primary cause of death was reported in single-arm PVE/HVE cohort studies (6.9 per cent, 12 of 175 patients). CONCLUSION Based on moderate/weak evidence, PVE/HVE seems to increase resectability of bi-lobar liver tumours with a comparable safety profile. Additionally, PVE/HVE resulted in faster and more pronounced hypertrophy compared with PVE alone.

Abstract
STUDY PURPOSE The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. METHODS The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. RESULTS Not applicable. CONCLUSION DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.

Abstract
Background: The opioid epidemic continues to erode communities across Pennsylvania (PA). Federal and PA state programs developed grants to establish Hub and Spoke programs for the expansion of medications for opioid use disorders (MOUD). Employing the telementoring platform Project ECHO (Extension for Community Health Outcomes), Penn State Health engaged the other seven grant awardees in a Collaborative Health Systems (CHS) ECHO. We conducted key informant interviews to better understand impact of the CHS ECHO on health systems collaboration and opioid crisis efforts. Methods: For eight one-hour sessions, each awardee presented their unique strategies, challenges, and opportunities. Using REDCap, program characteristics, such as number of waivered prescribers and number of patients served were collected at baseline. After completion of the sessions, key informant interviews were conducted to assess the impact of CHS ECHO on awardee's programs. Results: Analysis of key informant interviews revealed important themes to address opioid crisis efforts, including the need for strategic and proactive program reevaluation and the convenience of collaborative peer learning networks. Participants expressed benefits of the CHS ECHO including allowing space for discussion of challenges and best practices and facilitating conversation on collaborative targeted advocacy and systems-level improvements. Participants further reported bolstered motivation and confidence. Conclusions: Utilizing Project ECHO provided a bidirectional platform of learning and support that created important connections between institutions working to combat the opioid epidemic. CHS ECHO was a unique opportunity for productive and convenient peer learning across external partners. Open dialogue developed during CHS ECHO can continue to direct systems-levels improvements that benefit individual and population outcomes.

Abstract
BACKGROUND Health anxiety is an under-recognised but a frequent cause of distress. It is particularly common in general hospitals. METHODS We carried out an 8-year follow-up of medical out-patients with health anxiety (hypochondriasis) enrolled in a randomised-controlled trial in five general hospitals in London, Middlesex and Nottinghamshire. Randomisation was to a mean of six sessions of cognitive behaviour therapy adapted for health anxiety (CBT-HA) or to standard care in the clinics. The primary outcome was a change in score on the Short Health Anxiety Inventory, with generalised anxiety and depression as secondary outcomes. Of 444 patients aged 16-75 years seen in cardiology, endocrinology, gastroenterology, neurology and respiratory medicine clinics, 306 (68.9%) were followed-up 8 years after randomisation, including 36 who had died. The study is registered with controlled-trials.com, ISRCTN14565822. RESULTS There was a significant difference in the HAI score in favour of CBT-HA over standard care after 8 years [1.83, 95% confidence interval (CI) 0.25-3.40, p = 0.023], between group differences in generalised anxiety were less (0.54, 95% CI -0.29 to 1.36), p = 0.20, ns), but those for depression were greater at 8 years (1.22, 95% CI 0.42-2.01, p < 0.003) in CBT-HA than in standard care, most in standard care satisfying the criteria for clinical depression. Those seen by nurse therapists and in cardiology and gastrointestinal clinics achieved the greatest gains with CBT-HA, with greater improvement in both symptoms and social function. CONCLUSIONS CBT-HA is a highly long-term effective treatment for pathological health anxiety with long-term benefits. Standard care for health anxiety in medical clinics promotes depression. Nurse therapists are effective practitioners.

Abstract
Introduction The National Audit of Dementia (NAD) is funded by the Healthcare Quality Improvement Partnership to collect data from acute general hospital in England and Wales. In June 2020 NAD circulated optional surveys to leads for dementia in acute hospitals and carers asking about the impact of the pandemic on the organisation and provision of hospital care. Methods Anonymous survey links were sent to hospital dementia leads directly and circulated to carers of people with dementia via social media and representative organisations. Dementia Leads’ questions included whether they and/or their team had been redeployed during the pandemic and whether wards had access to specialist services. Carers’ questions included whether patients’ needs were discussed, whether they were permitted to visit/how this was communicated, any measures to facilitate communication with their loved ones, and whether they were updated about progress and discharge. Results 53 dementia hospital leads completed the questionnaire. 32% had been redeployed to other clinical areas during the pandemic, 45% said the same for members of the dementia team. Specialist support for people with dementia on both Covid and Non-Covid wards was significantly compromised. 32 carers completed the questionnaire. 48% were not asked about the needs of the patient they cared for, 90% not allowed to visit, 43% were not given any explanation about visiting and 48% not given support to keep in touch with their loved one. Conclusions Clinical priorities inevitably meant redeployment of dementia specialist staff, and changes to visiting. However, continuation of specialist support is a requirement for people with dementia admitted to hospital. Liaison with carers/families must be a priority, including facilitating remote support. Hospitals should take note of NHS guidance permitting carer visits to support a person with dementia experiencing distress.

Abstract
Abstract
Introduction
Lucid dreaming (being aware that one is dreaming) is typically a positive experience that may enhance positive mood even after waking. There is concern, however, that lucid dreaming may interfere with sleep quality. In the current experiment, participants practiced common lucid dream induction techniques over the course of a week, and kept a daily sleep and dream diary. The study objective was to assess relationships between dream lucidity and subjective sleep quality, dream emotional content, and subsequent waking mood.
Methods
There were 32 participants aged 19–33 in this open label, single arm study (mean=22.63±3.48; 6 males, 24 females). All participants completed a sleep and dream diary for 7 days that included scaled items (1–7 scale) concerning subjective sleep quality, negative and positive emotional intensity of a dream (if recalled). Participants also completed a 19-item lucidity questionnaire, and the Positive and Negative Affect Schedule. Average scores for the week were computed for all measures and Pearson’s correlations conducted between lucidity and all other measures. Participants with no dream recall (n=5) were excluded. Within-subjects analyses were undertaken by selecting each participant’s highest and lowest lucidity night (n=22; 5 participants with only minimum lucidity excluded).
Results
Positive correlations were found between lucidity and dream positive emotion (r=.490, n=27, p=.009) and positive waking mood (r=.638, n=27, p<.001); there were no other significant correlations (all p>.1). Higher lucidity was associated with more positive dream content (t(21)= -3.214, p=.004) and positive waking mood (t(25)=-4.568, p<.001); no other significant differences were observed.
Conclusion
These data indicate that lucidity is associated with positive dreams and waking mood, with no detriment to self-reported sleep quality. The findings provide preliminary support of lucid dreaming as an intervention to improve wellbeing and mood in the short term.

Abstract
Abstract
Introduction
The accurate estimation of sleep is critical for understanding who is most at risk for sleep disorders and associated disease outcomes. Individuals who overestimate sleep disturbances may be at increased risk for insomnia. A few studies have shown demographic differences in the accuracy of sleep estimation when comparing subjective and objective measures; however, the previous literature is inconsistent and focuses primarily on older adults. We sought to replicate these studies in a large sample of nurses using 14 days of sleep diary and actigraphy measures.
Methods
Participants were 392 nurses (91.8% female; 77.8% white, mean age = 39.54) recruited for a larger study. Participants completed 14 days of actigraphy and sleep diaries to prospectively assess total sleep time (TST) and sleep efficiency (SE). Discrepancy between diary and actigraphy measures was calculated by subtracting actigraphy measures from diary measures. Linear regression was used to examine how age, race (0 = race other than white, 1 = white), gender (1 = male, 2 = female), ethnicity (1= non-Hispanic/Latinx, 2 = Hispanic/Latinx) predicted degree of sleep discrepancy.
Results
The average discrepancy between diary and actigraphy TST was 30.29 minutes (SD = 29.28), and the average discrepancy between diary and actigraphy SE was 4.16% (SD = 5.66). Race and ethnicity did not predict amount of TST or SE discrepancy. However, younger individuals had more discrepancy in both TST (b = -0.48, p < .001) and SE (b = -0.09, p < .001). Men also had a greater discrepancy in both TST (b = -10.90, p < .05) and SE (b = -2.56, p < .05).
Conclusion
Men and younger individuals had greater discrepancies between diary and actigraphy measures of sleep. This is in contrast to some previous research showing that elderly women tend to display greater discrepancies between subjective and objective measures of sleep. It is essential that future research explore the discrepancies between subjective and objective measures of sleep in larger and more demographically diverse samples. Establishing a better understanding of this relationship is crucial, as it may have significant implications for the diagnosis and treatment of insomnia.

Abstract
Abstract
Background
Methamphetamine abuse is a growing public health crisis, affecting an estimated 33 millions users worldwide. It is associated with the development of several cardiac pathologies, however the incidence and predictors of cardiovascular disease among methamphetamine users remains unclear.
Purpose
We aim to describe the clinical characteristics of methamphetamine users identified from a large cohort of hospitalised patients. Through comparison of methamphetamine users who develop cardiovascular disease (CVD) with those who do not, we aim to identify predictors of these cardiac conditions.
Methods
We studied the clinical and sociodemographic characteristics (via ICD-9 codes) of methamphetamine users using a database of hospitalised patients in California, captured by the Healthcare Cost and Utilization Project (HCUP) between 2005–2011. We used Cox proportional hazards model for incidence of methamphetamine-associated cardiac pathologies (pulmonary hypertension, congestive heart failure, stroke and myocardial infarction) among methamphetamine users.
Results
Amongst 20,249,026 persons in HCUP, we identified n=66,199 patients as methamphetamine users. Methamphetamine users were younger (33±11.6 years) and more frequently male (63.3%) when compared to non-users (45±19.5 years, 44.4% male). They were also more likely to smoke (26% vs 4%) and concurrently abuse alcohol (7% vs 1%).
Methamphetamine use was associated with a 32% increased risk of CVD (HR 1.32, CI 1.26–1.38); higher than those who abuse alcohol (HR 1.28, CI 1.27–1.38), but lower than in those who abuse cocaine (HR 1.47, CI 1.40–1.54), when compared to non-users. Of the 4 CVD types studied, methamphetamine use was most strongly associated with the development of congestive heart failure (HR 1.53) and pulmonary hypertension (HR 1.42). Whilst male gender (HR 1.73) was a significant predictor of myocardial infarction among methamphetamine users, female gender was not found to be a significant risk factor for the development of any of the studied pathologies. Chronic Kidney Disease (HR 2.38, CI 1.74–3.25) and hypertension (HR 2.26, CI 2.03–2.51) were the risk factors most strongly associated with development of CVD among methamphetamine users.
A Kaplan-Meier plot was constructed (figure 1), comparing the time-to-event for development of CVD among users of either methamphetamine, alcohol or cocaine, with non-users. Methamphetamine and cocaine users both had a higher incidence of CVD after 5 years, when compared to those who abuse alcohol only.
Conclusions
Methamphetamine users are at increased risk of CVD when compared to the general hospitalised population. They have a similar risk of CVD as users of cocaine and a higher risk than those who abuse alcohol. Whilst male gender appears to be a risk factor for myocardial infarction among methamphetamine users, there was no significant association found between female gender and the development of CVD in this population.

Abstract
Background Health-care professional (HCP) students experience high levels of burnout, characterized by work- and school-related stress. Burnout is associated with a host of negative psychological and health outcomes. It may also contribute to cognitive dysfunction and decreased work productivity and may be related to trait mindfulness. This study cross-sectionally explored psychological distress and its correlates in a sample of interdisciplinary HCP students using cluster analysis. Method Fifty-seven interdisciplinary HCP students completed validated measures of burnout, depressive and anxiety symptoms, perceived stress, and rumination, which were entered into a cluster analysis. A neuropsychological test measured executive function; validated questionnaires assessed work productivity and trait mindfulness. Relationships between cluster membership and classroom productivity, executive function, and trait mindfulness were investigated. Results Burnout, depressive symptoms, and perceived stress were reported at high rates in this sample. The cluster analysis yielded 4 clusters, categorized as follows: Healthy, Ruminative Healthy, Moderate Distress, and High Distress. Cluster membership significantly differed based on trait mindfulness and classroom productivity. Trait mindfulness was related to classroom productivity. Although not significant, there were small to medium associations between executive function and both cluster membership and trait mindfulness. Discussion Cluster membership was highly related to trait mindfulness and classroom productivity, suggesting these are important correlates of psychological distress in HCP students. Taken together, these results underscore the need for interventions, especially ones that are mindfulness-based, to manage stress and work-relevant functioning in HCP students.

Abstract
Despite the widespread belief that the involvement of users and carers in the training of psychiatrists would provide a valuable addition to the training process, it is clear that many trainees do not receive this input as part of their current teaching. This article explores some of the questions and concerns that all those parties involved have raised and draws on the experience of users, carers and psychiatrists to address some of these issues and promote the further development of this practice.

Abstract
In 2015, there are a few absolute contraindications to liver transplantation. In adult patients, survival post-liver transplant is excellent, with 1-year survival rate >90% and 5-year survival rates >80% and predicted median allograft survival beyond 20 years. Patients with a Child-Turcotte Pugh score ≥9 or a model for end-stage liver disease (MELD) score >15 should be referred for liver transplantation, with patients who have a MELD score >17 showing a 1-year survival benefit with liver transplantation. A careful selection of hepatocellular cancer patients results in excellent outcomes, while consideration of extra-hepatic disease (reversible vs irreversible) and social support structures are crucial to patient assessment. Alcoholic liver disease remains a challenge, and the potential to cure hepatitis C virus infection together with the emerging issue of non-alcoholic fatty liver disease-associated chronic liver failure will change the landscape of the who in the years ahead. The when will continue to be determined largely by the severity of liver disease based on the MELD score for the foreseeable future.

Abstract
Acute or recurrent bleeding from ectopic varices is a potentially life-threatening condition in rare patients with extrahepatic complete portal vein thrombosis (PVT) after liver transplantation (LT). In this setting, the role of interventional radiology is very limited and surgical shunts, in particular splenorenal shunts are usually used, despite the high associated mortality. We present the first reports of the clinical use of a new minimally invasive technique, percutaneous retroperitoneal splenorenal shunt (PRESS), in two LT recipients with life-threatening variceal hemorrhage secondary to PVT. Both patients had a successful PRESS using a transplenic approach with resolution of bleeding, avoiding the need for a potentially complicated laparotomy. The PRESS procedure is a useful addition to the interventional armamentarium that can be used in cases unsuitable for surgical shunt, and refractory to endoscopic management. In the future, this technique may be an alternative to surgical shunts as the standard procedure in patients with extra-hepatic PVT, just as the transjugular intrahepatic portosystemic shunt (TIPS) procedure has become for the management of portal hypertension in the absence of PVT. Longer-term follow-up will be needed to establish the long-term success of this procedure.

Abstract
We demonstrate, for the first time, OCT imaging capabilities of a novel, akinetic (without any form of movement in the tuning mechanism), all-semiconductor, all-electronic tunable, compact and flexible swept source laser technology at 1550 nm and 1310 nm. To investigate its OCT performance, 2D and 3D ex vivo and in vivo OCT imaging was performed at different sweep rates, from 20 kHz up to 200 kHz, with different axial resolutions, about 10 µm to 20 µm, and at different coherence gate displacements, from zero delay to >17 cm. Laser source phase linearity and phase repeatability standard deviation of <2 mrad (<160 pm) were observed without external phase referencing, indicating that the laser operated close to the shot noise limit (~2 × factor); constant percentile wavelengths variations of sliding RIN and ortho RIN <0.2% could be demonstrated, ~5 times better as compared to other swept laser technologies.
