Correlation between neuroimaging, neurological phenotype, and functional outcomes in Wilson's disease.

INTRODUCTION: Wilson's disease (WD) is associated with a variety of movement disorders and progressive neurological dysfunction. The aim of this study was to correlate baseline brain magnetic resonance imaging (MRI) features with clinical phenotype and long-term outcomes in chronically treated WD patients. METHODS: Patients were retrospectively selected from an institutional database. Two experienced neuroradiologists reviewed baseline brain MRI. Functional assessment was performed using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) scale, and disease severity was classified using the Global Assessment Scale for Wilson's Disease (GASWD). RESULTS: Of 27 patients selected, 14 were female (51.9%), with a mean (standard deviation [SD]) age at onset of 19.5 (7.1) years. Neurological symptoms developed in 22 patients (81.5%), with hyperkinetic symptoms being the most common (70.4%). Baseline brain MRI showed abnormal findings in 18 cases (66.7%), including T2 hyperintensities in 59.3% and atrophy in 29.6%. After a mean (SD) follow-up of 20.9 (11.0) years, WD patients had a mean score of 19.2 (10.2) on WHODAS 2.0 and 6.4 (5.7) on GASWD. The presence of hyperkinetic symptoms correlated with putaminal T2 hyperintensities (p = 0.003), putaminal T2 hypointensities (p = 0.009), and mesencephalic T2 hyperintensities (p = 0.009). Increased functional disability was associated with brain atrophy (p = 0.007), diffusion abnormalities (p = 0.013), and burden of T2 hyperintensities (p = 0.002). A stepwise regression model identified atrophy as a predictor of increased WHODAS 2.0 (p = 0.023) and GASWD (p = 0.007) scores. CONCLUSIONS: Atrophy and, to a lesser extent, deep T2 hyperintensity are associated with functional disability and disease severity in long-term follow-up of WD patients.

Palliative care and end stage liver disease: A cohort analysis of palliative care use and factors associated with referral.

INTRODUCTION AND OBJECTIVES: Prevalence and mortality of chronic liver disease have risen significantly. In end stage liver disease, the survival of patients is approximately two years. Despite the poor prognosis and high symptom burden of these patients, integration of palliative care is limited. We aim to assess associated factors and trends in palliative care use in recent years. MATERIALS AND METHODS: A Multicenter retrospective cohort of patients with end stage liver disease who suffered in-hospital mortality between 2017 and 2019. Information regarding patient demographics, hospital characteristics, comorbidities, etiology, decompensations, and interventions was collected. Two-sided tests and logistic regression analysis were used to identify factors associated with palliative care use. RESULTS: A total of 201 patients were analyzed, with a yearly increase in palliative care consultation: 26.7 % in 2017 to 38.3 % in 2019. Patients in palliative care were older (65.72 ± 11.70 vs. 62.10 ± 11.44; p = 0.003), had a lower Karnofsky functionality scale (χ=18.104; p = 0.000) and had higher rates of hepatic encephalopathy (32.1 % vs. 17.4 %, p = 0.007) and hepatocarcinoma (61.7 % vs. 26.2 %; p = 0.000). No differences were found for Model for End-stage Liver Disease (19.28 ± 6.60 vs. 19,90 ± 5.78; p = 0.507) or Child-Pugh scores (p = 0.739). None of the patients who die in the intensive care unit receive palliative care (0 % vs 31.6 %; p = 0.000). Half of the palliative care consultations occurred 6,5 days before death. CONCLUSIONS: Palliative care use differs based on demographics, disease complications, and severity. Despite its increasing implementation, palliative care intervention occurs late. Future investigations should identify approaches to achieve an earlier and concurrent care model.

Sleep disturbances predict long-term changes in low back pain among Finnish firefighters: 13-year follow-up study.

PURPOSE: To investigate the prevalence of low back pain among Finnish firefighters and to examine whether sleep disturbances predict membership of low back pain trajectories. METHODS: In this prospective study, 360 actively working firefighters responded to a questionnaire in 1996, 1999 and 2009. The outcome variables were radiating and local low back pain during the preceding year. Using logistic regression modeling, the likelihood of membership of pain trajectories was predicted by sleep disturbances at baseline. RESULTS: During the 13-year follow-up, the prevalence of radiating low back pain increased from 16 to 29 % (p < 0.0001) and that of local low back pain from 28 to 40 % (p < 0.001). The following trajectories were identified: "pain free," "recovering," "new pain," "fluctuating" and "chronic." More than one-fifth of the participants belonged to the new pain trajectory as regards both pain types, 6 % of the participants belonged to the chronic radiating and 12 % to the chronic local low back pain trajectory. Those with sleep disturbances at baseline had a 2.4-fold risk (adjusted OR 2.4; 95 % CI 1.2-4.7) of belonging to the new pain or chronic radiating pain cluster compared to pain-free participants. CONCLUSIONS: This is the first prospective study to show that low back symptoms are common and persistent among firefighters and that sleep disturbances strongly predict membership of a radiating pain trajectory. Occupational health and safety personnel, as well as the firefighters themselves, should recognize sleep problems early enough in order to prevent back pain and its development into chronic pain.

Does the association between musculoskeletal pain and sickness absence due to musculoskeletal diagnoses depend on biomechanical working conditions?

AIM: To investigate single-site and multi-site musculoskeletal pain as predictors of future sickness absence due to musculoskeletal disorders (MSD) among blue-collar employees in food industry, and to study to what extent this relationship depends on physical loading at work. METHODS: Survey responses of 901 employees on working conditions and musculoskeletal pain during the past week were linked to their future sickness absence records obtained from the personnel register of a food industry company. Negative binomial regression models were computed to determine associations of pain in one and in multi-site with the number of sickness absence days due to MSD during a four-year follow-up. Analyses were made in the whole cohort and stratified by the occurrence of repetitive movements and awkward postures (low/high). RESULTS: Multi-site pain occurred among 59 % in the total cohort and predicted sickness absence with a rate ratio of 1.48 [95 % confidence interval (CI) 1.21-1.80], adjusted for age, gender, biomechanical and psychosocial working conditions, body mass index and physical exercise. Similar associations were seen in the sub-cohorts with a low occurrence of repetitive movements (RR 2.18, CI 1.69-2.80) and awkward postures (RR 1.78, CI 1.39-2.28), but not in the sub-cohorts with a high occurrence of these exposure. Single-site pain was not predictive of sickness absence. CONCLUSIONS: A very high level of sickness absence in biomechanically strenuous work was found. Multi-site pain predicted sickness absence due to MSD among the employees with low exposure, but not among those with high exposure.

Health Behaviors and Overweight in Nursing Home Employees: Contribution of Workplace Stressors and Implications for Worksite Health Promotion.

BACKGROUND: Many worksite health promotion programs ignore the potential influence of working conditions on unhealthy behaviors. METHODS: A study of nursing home employees (56% nursing aides) utilized a standardized questionnaire. We analyzed the cross-sectional associations between workplace stressors and obesity, cigarette smoking, and physical inactivity. RESULTS: Of 1506 respondents, 20% reported exposure to three or more workplace stressors (physical or organizational), such as lifting heavy loads, low decision latitude, low coworker support, regular night work, and physical assault. For each outcome, the prevalence ratio was between 1.5 and 2 for respondents with four or five job stressors. Individuals under age 40 had stronger associations between workplace stressors and smoking and obesity. CONCLUSIONS: Workplace stressors were strongly associated with smoking, obesity, and physical inactivity, even among the lowest-status workers. Current working conditions affected younger workers more than older workers. Although this study is cross-sectional, it has other strengths, including the broad range of work stressors studied. Strenuous physical work and psychosocial strain are common among low-wage workers such as nursing home aides. Workplace health promotion programs may be more effective if they include measures to reduce stressful work environment features, so that working conditions support rather than interfere with employee health.

The Use of Amiloride and Sodium-Glucose Cotransporter 2 Inhibitors in Cisplatin-Induced Hypomagnesemia: A Case Report and Review of the Literature.

Cisplatin, a chemotherapy agent widely used since its FDA approval in 1978 for testicular cancer, is associated with nephrotoxicity and hypomagnesemia. Magnesium supplementation is not only a treatment for hypomagnesemia but also a well-established agent in preventing cisplatin-induced nephrotoxicity (CIN). Considering the challenges associated with intravenous magnesium use and even with the supplementation of oral forms, there is a need for drugs that effectively reduce urinary magnesium excretion. Amiloride and sodium-glucose cotransporter 2 inhibitors (SGLT2 inhibitors) have emerged as potential candidates. Amiloride is a well-known potassium-sparing diuretic that also has a hypomagnesemia effect seen in preclinical data. SGLT2 inhibitors are a drug class initially used in diabetes that was also observed to have positive effects on cardiovascular mortality, diabetic kidney disease, and hypomagnesemia. SGLT2 inhibitors were found to reduce hypomagnesemia in a meta-analysis study of 18 trials. However, these trials were not specifically designed for the evaluation of hypomagnesemia, and their current use in hypomagnesemia is considered off-label.

Do physical or psychosocial factors at work predict multi-site musculoskeletal pain? A 4-year follow-up study in an industrial population.

PURPOSE: Musculoskeletal pain at multiple sites is common among working-age people and greatly increases work disability risk. Little is known of the work-related physical and psychosocial factors contributing to multi-site pain. METHODS: Survey responses from 734 employees (518 blue- and 216 white-collar; 65 % female) of a food processing company were collected twice, in 2005 and 2009. Information on musculoskeletal pain during the preceding week, and on environmental, biomechanical and psychosocial work exposures were obtained through a structured questionnaire. The association of multi-site pain with work exposures was estimated with logistic regression by gender and age group. RESULTS: At baseline, 54 % of informants reported pain in more than one area, and 50 % at 4-year follow-up. Forty percent of all employees had multi-site pain both at baseline and at follow-up. Among those with multi-site pain at baseline, 69 % had multi-site pain at follow-up. Both repetitive work and awkward work postures at baseline were associated with multi-site pain at follow-up. Psychosocial factors (low job satisfaction, low team spirit, and little opportunity to exert influence at work) also strongly predicted multi-site pain at follow-up, especially among younger workers and men. CONCLUSION: This prospective study provides new evidence of the high occurrence and persistence of musculoskeletal pain at multiple body sites in an industrial population with a strong association between biomechanical and psychosocial exposures at work and multi-site pain. Prevention of multi-site pain with many-sided modification of work exposures is likely to reduce work disability.

A narrative inquiry into women's experiences of menstruation at the workplace in Namibia.

Background: Menstruation's effects on workplace productivity and its impact on women's careers are rarely discussed in public discourse. This paper presents an analysis of thirteen women's accounts of their menstrual experiences at work. Objectives: The study aimed to understand women's lived experiences of menstruation in the workplace in Namibia and to make recommendations for best practices and policy formulation to help female employees cope with menstruation at work in Namibia. Materials and Methods: The study adopted a qualitative, phenomenological narrative inquiry research design, and thirteen participants working in various institutions and companies in Namibia were selected through a snowball sampling procedure. Individuals who agreed to participate in the study were given a link to a Google document containing reflective questions. Results: Thematic analysis was used to analyze the narratives. The study findings show that most participants experienced various menstrual-related symptoms ranging from unbearable physical pain or discomfort to heavy bleeding and psychological distress. Menstruating women face workplace challenges, such as a lack of emergency sanitary products and unsupportive superiors. Conclusions: Based on the narratives analyzed, we conclude that menstrual-related symptoms affect work productivity. Participants highlighted that they perform better and are considerably more productive on their non-menstrual days. Participants advocated for a shift in policy to allow flexibility to work from home or get menstrual leave when experiencing severe menstrual symptoms. Such a change will go a long way in making the workplace more accommodating to women.

Palliative Care in Advanced Liver Disease: Similar or Different Palliative Care Needs in Patients with a Prospect of Transplantation? Prospective Study from a Portuguese University Hospital and Transplantation Center.

Background and Aims: End-stage liver disease (ESLD) is an important cause of morbidity and mortality, comparable to a large extent to other organ insufficiencies. The need for palliative care (PC) in patients with ESLD is high. In Portugal, in the only identified study, more than 80% of patients hospitalized with ESLD had criteria for PC. No results specified which needs they identified or their transplantation prospect status. Methods: Prospective observational study including 54 ESLD patients who presented to a university hospital and transplantation center, between November 2019 and September 2020. Assessment of their PC needs through the application of NECPAL CCOMS-ICO© and IPOS, considering their transplantation perspective status. Results: Of the 54 patients, 5 (9.3%) were on active waiting list for transplantation and 8 (14.8%) under evaluation. NECPAL CCOMS-ICO© identified 23 patients (n = 42.6%) that would benefit from PC. Assessment of PC needs by clinicians, functional markers and significant comorbidities were the most frequent criteria (47.8%, n = 11). IPOS also revealed a different sort of needs: on average, each patient identified about 9 needs (8.9 ±2.8). Among the symptoms identified, weakness (77.8%), reduced mobility (70.3%), and pain (48.1%) stood out, as well as the psychoemotional symptoms of depression (66.7%) and anxiety (77.8%). There were no significant differences between the subgroups of patients analyzed. Only 4 patients (7.4%) were followed by the PC team. Conclusion: All the ESLD patients included, independently of the group they belonged to, presented with PC needs. No significant differences between the subgroups of patients were identified, confirming that even patients with a transplantation prospect have important needs for PC.

Introdução e objetivos: A doença hepática avançada (DHA) é uma causa importante de morbilidade e mortalidade, comparável em grande medida a outras insuficiências de órgão. A necessidade de cuidados paliativos (CP) em doentes com DHA é elevada. Em Portugal, no único estudo identificado até ao momento, mais de 80% dos doentes hospitalizados com DHA apresentavam critérios para CP. Não foram especificadas que necessidades de CP nem a perspetiva de transplante dos referidos doentes, que com o presente estudo se pretende ajudar a esclarecer. Métodos: Estudo prospectivo observacional incluindo 54 doentes com DHA assistidos num hospital universitário e centro de transplante, entre novembro de 2019 e setembro de 2020. Avaliação das necessidades de CP por meio da aplicação do NECPAL CCOMS-ICO© e IPOS, considerando a sua perspectiva de transplante. Resultados: Dos 54 doentes, cinco (9,3%) estavam em lista de espera ativa para transplante e oito (14,8%) em avaliação. O NECPAL CCOMS-ICO© identificou 23 doentes (n = 42,6%) que beneficiariam de CP. A avaliação das necessidades de CP por médicos, os marcadores funcionais e as comorbidades significativas foram os critérios mais frequentes (47,8%, n = 11). O IPOS também revelou diversas necessidades de CP: em média, cada doente identificou cerca de 9 necessidades (8,9 + −2,8). Entre os sintomas identificados, destacaram-se a fraqueza (77,8%), a mobilidade reduzida (70,3%) e a dor (48,1%), bem como os sintomas psicoemocionais de depressão (66,7%) e ansiedade (77,8%). Não houve diferenças significativas entre os subgrupos de doentes analisados. Apenas 4 doentes (7,4%) foram acompanhados pela equipa intra-hospitalar de CP. Conclusão: Todos os doentes com DHA incluídos, independentemente do grupo a que pertenciam, apresentaram necessidades de CP. Não foram identificadas diferenças significativas entre os subgrupos de doentes, confirmando que mesmo os doentes com perspectiva de transplante têm importantes necessidades de CP.

Prognostic Impact of Type 2 Diabetes in Metastatic Colorectal Cancer.

Background Diabetes mellitus (DM) is a prognostic factor for some malignancies, but its clinical implications in metastatic colorectal cancer (mCRC) patients are less clear. Therefore, we conducted a retrospective study to evaluate the impact of pre-existing type 2 diabetes mellitus (T2DM) on the survival outcomes of patients with newly diagnosed mCRC. Methodology We retrospectively included patients with newly diagnosed mCRC between January 2017 and June 2021 and with pre-existing T2DM. Data on the characteristics of patients, clinicopathological features, and drug exposure were collected from the electronic medical records. The primary endpoint was overall survival (OS). Secondary endpoints were progression-free survival (PFS) and treatment-related adverse events (TRAEs). Results Among 187 mCRC patients, 54 (28.8%) had T2DM. The median follow-up was 25 months. We observed 150 OS events and 168 PFS events. Diabetes significantly and negatively impacted PFS and OS. The median for PFS (mPFS) was eight and 16 months for T2DM and no T2DM patients, respectively (p < 0.0001; log-rank test). The median overall survival (mOS) was 15 and 29 months for T2DM and no T2DM patients, respectively (p < 0.0001; log-rank test). Patients with diabetes were more often overweight or obese (59.3% vs. 24.8%; p < 0.01) and had a poorer performance status (53.7% vs. 21.1% with Eastern Cooperative Oncology Group Performance Status 1; p < 0.01). Additionally, T2DM patients had more high-risk pathological features, including G3 grading tumors (27.7% vs. 12.0%; p = 0.01), lymph node involvement (p < 0.01), BRAF-mutated (35.1% vs. 6.8%; p < 0.01), and right-sided CRC (63.0% vs. 30.1%; p < 0.01). We found no statistically significant differences in TRAEs. Nevertheless, a significantly higher rate of grade 2-4 peripheral neuropathy (22.2% vs. 5.3%; p < 0.01) was reported in T2DM patients. Conclusions T2DM is a negative prognostic factor for survival in mCRC. The paper provides empirical evidence in favor of the joint control of both pathologies. Further research is needed to establish the robustness of our results.

Trace Element Imbalances in Acquired Hepatocerebral Degeneration and Changes after Liver Transplant.

Brain manganese (Mn) accumulation is a key feature in patients with acquired hepatocerebral degeneration (AHD). The role of trace elements other than Mn in AHD needs to be clarified. In this study, using inductively coupled plasma mass spectrometry, we aimed to evaluate blood levels of trace elements in patients with AHD before and after liver transplantation (LT). Trace element levels in the AHD group were also compared with those of healthy controls (blood donors, n = 51). Fifty-one AHD patients were included in the study (mean age: 59.2 ± 10.6 years; men: 72.5%). AHD patients had higher levels of Mn, Li, B, Ni, As, Sr, Mo, Cd, Sb, Tl and Pb and a higher Cu/Se ratio, and lower levels of Se and Rb. Six patients (two women; mean age 55 ± 8.7 years) underwent LT, and there was an improvement in neurological symptoms, a significant increase in the Zn, Se and Sr levels, and a decrease in the Cu/Zn and Cu/Se ratios. In summary, several trace element imbalances were identified in AHD patients. Liver transplantation resulted in the improvement of neurological manifestations and the oxidant/inflammatory status. It is possible that observed changes in trace element levels may play a role in the pathophysiology and symptomatology of AHD.

Trends in musculoskeletal disorders and related health care utilization among conscripts in Finland, 1967-2006.

OBJECTIVES: The aim was to investigate time trends in musculoskeletal disorders (MSDs) among Finnish conscripts over a period of 40 years. METHODS: A nationally representative health examination survey (the Health 2000 study) was carried out in 2000-2001 among 10,000 adult Finns. All 18- to 50-year-old men were further sampled (n = 2674) and those with completion of the 6 to 12 month compulsory service were included. (n = 2296). Time trends in consultations because of MSDs during service and findings at call-up examinations were analysed. RESULTS: From 1967 to 2006 altogether 4872 MSD-related consultations were done, most commonly because of problems in the ankle or foot, knee, or back. The proportion of conscripts visiting military health care because of MSDs increased 1.6-fold (from 44 to 72%). The average number of MSD-related consultations per conscript tripled. The proportion of conscripts with > or = 6 consultations increased 5-fold and those seeking care for multisite symptoms increased 10-fold. No increase in symptoms or findings before service could be seen at preservice examinations. CONCLUSIONS: Conscripts seek care because of musculoskeletal symptoms considerably more often nowadays than before. More attention should be focused to the prevention of traumatic and overexertion injuries of the lower limbs, although the reasons for increasing careseeking should be further investigated.

Pembrolizumab-Induced Autoimmune Grade 4 Neutropenia in a Patient With Advanced Bladder Cancer: A Case Report.

Neutropenia is amongst the rare, but potentially life-threatening complications of immune checkpoint inhibitors (ICI). Awareness about this dangerous toxicity and its adequate treatment since early detection is of utmost importance. Unfortunately, there are no therapeutical guidelines to deal with neutropenia specifically. The best alternative is informed extrapolations based on reported neutropenia cases and established guidelines for other immune-related adverse events. We report a case of pembrolizumab-related grade 4 neutropenia in a patient with metastatic bladder cancer. She was successfully treated with immunosuppressive and supportive measures. Further studies are required to understand the range of immune-related adverse events and to improve their management.

Cutaneous and Cerebral Metastases From Primary Peritoneal Clear Cell Carcinoma.

Peritoneal tumors are very uncommon and among them, primary peritoneal clear cell carcinoma is extremely rare and often misdiagnosed as others subtypes. There are only 13 cases of primary peritoneal clear cell carcinoma previously reported in the literature and there are no reports about cutaneous metastasis in this setting and only brain metastases were described to be associated with other primary peritoneal carcinoma subtypes. More information about this topic is needed and so we are presenting a new case of primary peritoneal clear cell carcinoma with cutaneous and cerebral metastases in a 34-year-old female.

Brain MRI in the Decision for Liver Transplantation in Pediatric Neurological Wilson's Disease.

Background: Neurological Wilson's disease (WD) presentation in the pediatric population is rare, and liver transplantation (LT) in these patients remains controversial. The aim of the present study was to assess the role of brain magnetic resonance imaging (MRI) in predicting reversion of brain lesions and neurological outcomes in pediatric WD patients after LT. Methods: Patients with confirmed WD (Leipzig score ≥4), disease onset in pediatric age (<18 years), neurological involvement, and submitted to LT were selected. Clinical records and pre- and post-LT brain MRI were evaluated. Results: Six patients met the pre-defined inclusion criteria, one of whom died shortly after LT and was excluded. The indication for LT was end-stage liver disease in two patients and neurological worsening despite optimized treatment in three patients. After LT, the neurological picture progressively improved in all patients. Pre-LT brain MRI showed T1-weighted hyperintensities in four patients, which quickly resolved afterward. T2-weighted hyperintensities were observed in four patients before LT, completely resolving in one patient, stabilizing in two, and improving in one after LT. A direct correlation could not be found between clinical and neuroradiological improvement. Progressive clinical improvement was observed even in patients with irreversible brain MRI changes. Conversely, some patients with normal MRI had only slight neurological improvement. Conclusions: The pattern of T2-weighted hyperintensities after LT was unpredictable and did not correlate with neurological outcomes, suggesting that these changes may not entail irreversible clinical damage. Therefore, brain MRI does not seem to have prognostic value for assessing clinical response to LT.

Impact of Human Epidermal Growth Factor Receptor 2 (HER2) Low Status in Response to Neoadjuvant Chemotherapy in Early Breast Cancer.

Introduction In clinical practice, there is a binary distinction between human epidermal growth factor receptor 2 (HER2)-positive and HER2-negative (HER2-) breast cancer (BC). However, within HER2- disease, there is significant heterogeneity. Particularly, HER2- tumors that express some level of HER2 by immunohistochemistry (IHC) score 1+ or 2+/in situ hybridization (ISH) non-amplified are currently defined as HER2-low. This subgroup has shown distinct biological features compared to HER2-zero (HER2-0) BC and additionally novel antibody-drug conjugate therapies have demonstrated a potential and promising activity in HER2-low BC population. This study aims to evaluate the impact of HER2-low status in response to neoadjuvant chemotherapy (NACT) in HER2- BC being HER2-low and HER2-0 status. Materials and methods In a single institution, we retrospectively reviewed clinical and pathological data of HER2 early-stage BC patients treated with NACT following definitive surgery from January 2015 to December 2020. Tumors with HER2 IHC 0 were classified as HER2-0 and IHC score 1+ and 2+/ISH non-amplified as HER2-low. The primary objective was to evaluate the rate of pathological complete response (pCR) using the definition of ypT0/Tis ypN0 according to HER2-low and HER2-0 subgroups. Secondary objectives were to evaluate biological features between the two subgroups, disease-free survival (DFS), and overall survival (OS). Pearson chi-square, Fisher's exact, and Mann-Whitney tests were performed. The Kaplan-Meier method was used to plot DFS and OS curves. A p-value of <0.05 was considered statistically significant. Results A total of 72 patients with HER2 BC were included with a median age at diagnosis of 52.5 years and a median follow-up time of 35.5 months. Of patients, 56.9% had HER2-low disease and 43.1% had HER2-0 disease. Significant differences between the two subgroups were detected regarding hormonal receptor status and proliferation grade (Ki67). In the HER2-low subgroup, 70% of tumors were luminal-like and 64.5% of HER2-0 patients had triple-negative BC (p = 0.03). There were statistically significant differences regarding estrogen (p = 0.00) and progesterone (p = 0.02) receptors. The median Ki67 rate was higher in the HER2-0 subset (mean rank = 43.9) compared to HER2-low (mean rank = 30.9) and this difference was statistically significant (p = 0.00). HER2-low patients presented more stage III tumors (65.9%) and HER2-0 patients were mainly stage II (61.3%), and this was statistically relevant (p = 0.03). The prevalence of other clinical and pathological features was comparable between both groups. HER2-low subgroup achieved lower pCR rates (14.6% vs. 29.0%) but this difference was not statistically significant (p = 0.15). Similarly, there was no difference between the two subgroups regarding DFS (p = 0.97) and OS (p = 0.35), although the data were immature. Conclusion As in prior studies, this study did not support a significant impact of HER2-low status on response to NACT in HER2- patients with early-stage BC. HER2-low patients had a lower pCR, which may suggest a worse response to classic chemotherapy regimen and may have clinical implications that should be further exploited. The prevalence of hormonal receptors in HER2-low tumors was consistent with previous data in the literature. Although retrospective, the data suggest that HER2-low tumors should be regarded as a distinct biological subtype and more research is warranted.

Violence at the workplace increases the risk of musculoskeletal pain among nursing home workers.

BACKGROUND: Despite the high prevalences of workplace physical violence and musculoskeletal symptoms among health care workers, very few studies have examined the relationship between these two phenomena. METHODS: We surveyed 920 clinical nursing home workers by questionnaire regarding musculoskeletal pain in the low back, shoulders, wrists or hands, and knees. Information was also collected on exposure to physical assaults at work during the preceding 3 months, other workplace safety features, physical workload and psychosocial work environment. Log-binomial regression was used to estimate the prevalence ratios (PR) with 95% CIs. RESULTS: Almost one-half of respondents reported being assaulted at least once during the preceding 3 months by a resident or resident's visitor. The prevalence of low back pain increased from 40% among non-assaulted workers to 70% among those assaulted three or more times. The highest risk was found for widespread pain (three or more areas), with an adjusted PR of 2.7 (95% CI 1.8 to 3.9) for workers assaulted three or more times. Good workplace safety buffered the effects, so that violence increased the risk of most pains considerably less in a work environment perceived to be safe. CONCLUSIONS: To our knowledge, this is the first study to show a dose-response association between physical assaults and musculoskeletal pain in a health care setting where violence is a frequent occurrence. This emphasises the need to address violence as a workplace hazard through practical measures for prevention as well as in future aetiological research on musculoskeletal disorders.

The distribution and co-occurrence of physical and psychosocial risk factors for musculoskeletal disorders in a general working population.

BACKGROUND: There is growing evidence that physical and psychosocial exposures at work increase the risk of musculoskeletal disorders. The aim of this study was to describe the distribution and co-occurrence of these risk factors in the working population. METHODS: We used data from the Health 2000 survey carried out in Finland in 2000-2001. The sample of our study consisted of 2,491 men and 2,613 women who had been actively working during the year preceding the survey. Logistic regression and exploratory factor analysis were used to analyze the co-occurrence of the work-related risk factors. RESULTS: Exposure to high physical work load and several co-occurring work load factors was more prevalent among men than women. In women, as opposed to men, the highest exposure to most physical work load factors was found in their later work life. Gender and age showed weak associations with psychosocial work load factors. Low socioeconomic position, in both genders, was related to an increased risk of being exposed to several co-occurring physical or psychosocial factors. Physical exposures most frequently co-occurred with high job demands and low job control in men. Among women, physical exposures were found to co-occur with high job demands, low job control and job insecurity. CONCLUSIONS: This study provides novel information on the occupational exposures in general working population. It appears that co-occurrence of physical and psychosocial exposures should be considered in research and prevention of musculoskeletal disorders. In addition, a broader set of occupational factors, e.g., work organization, are suggested to be included in future studies to cover all the relevant determinants.

Systemic inflammation as a risk factor for portal vein thrombosis in cirrhosis: a prospective longitudinal study.

BACKGROUND AND AIMS: Various risk factors for portal vein thrombosis (PVT) development in patients with cirrhosis have been identified, but the role of systemic inflammatory reaction is unknown. The study aims to assess the association between markers of systemic inflammation and PVT in cirrhosis. METHODS: Between January 2014 and October 2015, 107 outpatients with cirrhosis and no PVT were recruited, and followed till February 2017. White blood cell count, serum concentrations of high-sensitive C-reactive protein, ferritin, tumor necrosis factor-alpha and interleukin-6 (IL-6) were evaluated at baseline and every 3 or 6 months till PVT diagnosis or end of follow-up. RESULTS: Median age, model for end-stage liver disease (MELD) score and follow-up period of the studied population was 55 years (IQR 46-62 years), 9.6 points (IQR 7.5-12 points) and 19 months (12-24 months), respectively. PVT developed in 10.3% of the patients. Lymphocyte count below 1.2 ´ 109/L [hazard ratio, 6.04; 95% confidence interval (CI), 1.29-28.2; P = 0.022], IL-6 above 5.5 pg/mL (hazard ratio, 5.64; 95% CI, 1.21-26.33; P = 0.028) and neutrophil-to-lymphocyte ratio (hazard ratio, 1.46; 95% CI, 1.04-2.04; P = 0.028) were associated with a higher risk of PVT development. IL-6 and lymphopenia remained associated with subsequent PVT development after adjustment for nonselective beta-blockers, spleen size, portosystemic collaterals, oesophageal varices (grade ≥2) and ascites, but also with alcohol as the cause for cirrhosis and MELD ≥13. CONCLUSION: In patients with cirrhosis, markers of systemic inflammation IL-6 and lymphopenia are predictive of PVT independently of markers of portal hypertension. These results draw our attention on a factor so far overlooked in the pathogenesis of PVT.
