Algorithms for Early Detection of Silent Liver Fibrosis in the Primary Care Setting.

More than one-third of the adult world population has steatotic liver disease (SLD), with a few percent of individuals developing cirrhosis after decades of silent liver fibrosis accumulation. Lack of systematic early detection causes most patients to be diagnosed late, after decompensation, when treatment has limited effect and survival is poor. Unfortunately, no isolated screening test in primary care can sufficiently predict advanced fibrosis from SLD. Recent efforts, therefore, combine several parameters into screening algorithms, to increase diagnostic accuracy. Besides patient selection, for example, by specific characteristics, algorithms include nonpatented or patented blood tests and liver stiffness measurements using elastography-based techniques. Algorithms can be composed as a set of sequential tests, as recommended by most guidelines on primary care pathways. Future use of algorithms that are easy to interpret, cheap, and semiautomatic will improve the management of patients with SLD, to the benefit of global health care systems.

Screening for Fibrosis Promotes Lifestyle Changes: A Prospective Cohort Study in 4796 Individuals.

BACKGROUND AND AIMS: Early detection of liver fibrosis is believed to promote lifestyle changes. We evaluated self-reported changes in alcohol intake, diet, exercise, and weight after participating in a screening study for liver fibrosis. METHODS: We conducted a prospective screening study of individuals at risk of alcohol-related liver disease (ALD) or metabolic dysfunction-associated steatotic liver disease (MASLD). We provided lifestyle advice to all participants and evaluated lifestyle changes by questionnaires after 1 week and 6 months, with re-examination of a subgroup after 2 years. RESULTS: A total of 1850 at risk of ALD and 2946 at risk of MASLD were included, of whom 383 (8%) were screening positive (transient elastography ≥8 kPa). A total of 84% replied to the 6-month questionnaire. In ALD participants, excessive drinking decreased from 46% to 32% after 6 months. Only 15% reported increased drinking, without differences between screening positive and negative individuals (P = .698). In high-risk drinkers, a positive screening test predicted abstinence or decreased alcohol use after 6 months (odds ratio, 2.45; 95% confidence interval, 1.32-4.57; P = .005). After 2 years, excessive drinking decreased from 52% to 41% in a subgroup of 752 individuals and a positive screening test predicted abstinence or decreased alcohol use after 2 years (odds ratio, 1.84; 95% confidence interval, 1.09-3.11, P = .023). MASLD participants showed similar improvements: 35% improved their diet, 22% exercised more, and 13% reported a weight loss ≥5% after 6 months. CONCLUSIONS: Screening for liver fibrosis is associated with sustained improvements in alcohol consumption, diet, weight, and exercise in at-risk ALD and MASLD. The changes are most pronounced in screening positive participants but not limited to this group.

The risk of developing seizures before and after primary brain surgery of low- and high-grade gliomas.

OBJECTIVE: To identify risk factors for developing seizures pre- and postoperatively in low- and high-grade gliomas. PATIENTS AND METHODS: 282 patients undergoing neurosurgical tumor resection between 2013-2015 were included in the present single-center retrospective cohort study. Seizure incidences according to various variables were described. Univariate and multivariate logistic regression analyses were performed to identify significant risk factors for both pre- and postoperative seizures. RESULTS: 37.6% of patients presented with seizures before surgery, 18.4% developed seizures in the postoperative course, and 55.0% had no record of seizures pre- or postoperatively. Focal, cognitive, and other symptoms, tumors located in a non-eloquent area, and tumors ≥ 40 mm in diameter were found to be associated with a reduced risk of preoperative seizures, whereas hypertension or no comorbidity posed an increased risk. The presence of seizures pre- or perioperatively (≤ 24 h before and after surgery), and tumors located in the thalamus were associated with an increased risk of seizures in the postoperative course. CONCLUSION: Predictors for pre- and postoperative seizures identified in this study should be taken into account and integrated into the present knowledge, when determining patients at increased risk of developing seizures. Future prospective studies investigating the efficacy of prophylactic antiepileptic therapy in subgroups of glioma patients are needed before applied into clinical practice.

Voluntary activation of the trapezius muscle in cases with neck/shoulder pain compared to healthy controls.

Subjects reporting neck/shoulder pain have been shown to generate less force during maximal voluntary isometric contractions (MVC) of the shoulder muscles compared to healthy controls. This has been suggested to be caused by a pain-related decrease in voluntary activation (VA) rather than lack of muscle mass. The aim of the present study was to investigate VA of the trapezius muscle during MVCs in subjects with and without neck/shoulder pain by use of the twitch interpolation technique. Ten cases suffering from pain and ten age and gender matched, healthy controls were included in the study. Upper trapezius muscle thickness was measured using ultrasonography and pain intensity was measured on a 100mm visual analog scale (VAS). VA was calculated from five maximal muscle activation attempts. Superimposed stimuli were delivered to the accessory nerve at peak force and during a 2% MVC following the maximal contraction. Presented as mean±SD for cases and controls, respectively: VAS; 16.0±14.4mm and 2.1±4.1mm (P=0.004), MVC; 545±161N and 664±195N (P=0.016), upper trapezius muscle thickness; 10.9±1.9mm and 10.4±1.5mm (P=0.20), VA; 93.6±14.2% and 96.3±6.0% (P=0.29). In spite of significantly eight-fold higher pain intensity and ∼20% lower MVC for cases compared to controls, no difference was found in VA. Possible explanations for the reduction in MVC could be differences in co-activation of antagonists and synergists as well as muscle quality.

Musculoskeletal pain among surgeons performing minimally invasive surgery: a systematic review.

BACKGROUND: Musculoskeletal pain is the most common occupational disease in Europe. Surgeons with awkward and static working postures are no exception. Robotic-assisted laparoscopy has been postulated to be superior to conventional laparoscopy regarding the ergonomic strain for surgeons. In this review, we aimed to systematically evaluate the existing literature comparing the two surgical modalities. METHODS: A systematic literature search was employed in PubMed, Embase and Cochrane Library in spring 2015. Inclusion criteria were as follows: English language, full text available, original data, and comparative data on surgeons' physical workload with robotic-assisted laparoscopy and conventional laparoscopy. Studies only describing a single surgical modality were excluded. We applied the checklist, STrengthening the Reporting of OBservational studies in Epidemiology (STROBE), to assess the quality of reporting of the included studies. Semi-quantitative comparisons were made. RESULTS: In total, 2685 records were screened and 15 articles were included in the analysis. All studies were observational with sample sizes ranging from one single surgeon to 250 questionnaire responses. None of the studies fully fulfilled the criteria of STROBE, with an average score of 13 (range 10-16) out of 18. DISCUSSION: Results, mainly self-reported measures, suggest that robotic-assisted laparoscopy is less strenuous compared with conventional laparoscopy. However, results are limited by the large methodological heterogeneity and a high risk of bias. We advocate for further high-quality exposure studies to assess the potential ergonomic deficits related to different minimally invasive surgical techniques. In addition, future intervention studies should evaluate possible means to alleviate and prevent musculoskeletal pain among surgeons.
