ABSTRACT

OBJECTIVE: To compare the efficacy of percutaneous compression plate and cannulated compression screw in the treatment of displaced femoral neck fractures in young and middle-aged patients.

METHODS: From January 2015 to July 2020, 68 young and middle-aged patients with displaced femoral neck fracture were retrospectively analyzed. Among them, 31 cases were fixed by percutaneous compression plate (PCCP), and 37 cases were fixed by cannulated compression screw (CCS). General data such as gender, age, cause of injury, comorbidities, fracture classification and cause of injury of two groups were collected. The operation time, intraoperative blood loss, hospital stay, full weight bearing time, fracture healing time, visual analogue scale(VAS), Harris hip score and complications were compared between two groups.

RESULTS: Patients in both groups were followed up for more than 2 years. There were no significant differences in operation time, intraoperative blood loss, fracture reduction quality, hospital stay and VAS between two groups. The fracture healing time in PCCP group was significantly shorter than that in CCS group (t=-4.404, P=0.000). The complete weight bearing time of PCCP group was significantly shorter than that of CCS group (t=-9.011, P=0.000). Harris score of hip joint in PCCP group was better than that in CCS group 2 years after operation (P=0.002). Complications occurred in 3 cases (9.68%) in PCCP group, while 11 cases (29.72%) in CCS group, with a statistically significant difference (P=0.042).

CONCLUSION: Both PCCP and CCS can be used for the treatment of displaced femoral neck fractures in young and middle-aged people. Compared with CCS, PCCP fixation can achieve shorter fracture healing time and create conditions for early full weight bearing. PCCP results in higher hip score and lower complications.

ABSTRACT

Treatment of medically compromised patients with eating disorders is difficult in general hospital wards. There is currently no consensus on the best feeding method, however previous research has demonstrated the safety of using enteral feeding. As an oral diet has benefits on psychological and behavioural pathways, concurrent feeding requires further investigation. This research aimed to examine acceptability and safety of implementing mini meals to a previously nil-by-mouth seven-day enteral feeding protocol. This was mixed methods research including a retrospective observational study and participant survey. Patients admitted to a tertiary hospital in Brisbane, Australia between July 2020 and March 2021 were eligible. Eligible participants were provided mini meals from day five. Type and quantity of meals consumed alongside clinical incident data were collected. The survey examined acceptability of mini meals. Descriptive statistics were used to interpret findings. Content analyses were conducted on survey responses. Sixty-four participants (95% (n=57/60) female, 25.2±8.9 years, 75% (n=45/60) diagnosed with anorexia nervosa) were included. At least half of the participants consumed some or all of the mini meals at each meal period. No clinical incidents were reported. Twenty-six (50%, n=26/52) surveys were returned. Half (54%, n=14/26) agreed-strongly agreed that mini meals improved their experience. Eleven participants desired more choice in menu items. This study found that introducing mini meals into an enteral feeding protocol is acceptable and safe for patients with eating disorders. Participants reported benefits in returning to eating, however some items on the menu require reconsideration to enable increased consumption. This article is protected by copyright.

ABSTRACT

BACKGROUND: Vitamin D insufficiency is a common public health problem that is often unrecognized in children with congenital heart disease, and is not generally evaluated at congenital heart disease (CHD) follow-up. Recent studies have suggested that inadequate vitamin D status may have an adverse effect on cardiovascular health. This study investigates the relationship between vitamin D levels and hemodynamic parameters in children with CHD.

METHODS: Included in the study 40 patients (25 females, 15 males) with CHD, who were evaluated for Ross heart failure score, vitamin D, parathyroid hormone (PTH), calcium, phosphorus, alkaline phosphatase (ALP), whole blood count (WBC) and echocardiographic measurements, and all measurements were repeated in the third month of the therapy.

RESULTS: The mean vitamin D level was 16.4 ± 6.6 ug/L before and 27.5 ± 9.9 μg/L in the third month of therapy, while the mean PTH level was 53.3 ± 34.9 pg/mL before and 43.8 ± 21.4 pg/mL in the third month of therapy. The mean WBC was 8084 ± 2324/µL before and 7378±1893/µL in the third month of the therapy, and the mean platelet (PLT) count was 280,897 ± 80,119/µL before and 307,179 ± 60,202/µL in the third month of the therapy. The mean ejection fraction (EF) was 64% ± 7.2% before and 66.7% ± 6.2% in the third month of therapy, while the right ventricle (RV) myocardial performance index (MPI) was 32.1% ± 6.7% before and 28.9% ± 6.5% in the third month of the therapy. IL10 level was increased in four patients in the third month of therapy. A statistically significant decrease in PTH level and WBC, and an increase in PLT number and IL-10 level were detected by the therapy. Furthermore, echocardiographic findings revealed a statistically significant increase in EF and a decrease in RVMPI attributable to the therapy.

DISCUSSION: The decreased levels of PTH, which is a proinflammatory marker, the increases in IL-10, which is an antiinflammatory cytokine, and the decreases in the number of WBC resulting from vitamin D treatment demonstrate the antiinflammatory effects of vitamin D. An improvement in EF means improvement in left ventricular contractility, while a decrease in RV MPI has been shown to improve the systolic and diastolic function of the right ventricle. These results suggest that vitamin D therapy has a positive effect on the heart, and so vitamin D levels should be evaluated during the routine follow-up of congenital heart disease.

ABSTRACT

BACKGROUND: Sarcopenia and dementia are growing concerns among older adults that muscle and brain atrophy may cooccur. We aimed to compare the age-related loss of muscle mass by using ultrasound (US), and skeletal muscle mass index (SMI) by bioelectrical impedance analysis in older adults with and without dementia.

METHODS: A total of 221 older adults aged ≥65 years were included in the study. The diagnosis of sarcopenia was established if low muscle mass according to either SMI or sonographic gastrocnemius (GC) muscle thickness was combined with low grip strength. The diagnosis of dementia was based on the National Institute of Aging and Alzheimer’s Association criteria and the major neurocognitive disorder definition in the Diagnostic and Statistical Manual of Mental Disorders-V. Muscle strength was measured by hand dynamometer and physical performance was assessed by 4-meter usual gait speed.

RESULTS: There were similar/moderate correlation coefficients between GC muscle thickness and SMI with functional parameters (all p < 0.01). Forty-six patients (20.8%) had dementia, and 21 (45.7%) of them had sarcopenia diagnosed by GC thickness (p < 0.001). Age was older but weight, body mass index, and all sarcopenia-related parameters were lower in dementia patients (all p < 0.01). When clinical variables were taken into binary logistic regression analyses, age [OR = 1.095 (95% CI: 1.028-1.167)], weight [OR = 0.918 (95% CI: 0.887-0.950)], and presence of dementia [OR = 5.109 (95% CI: 2.002-13.033)] were independently associated with sarcopenia diagnosed with GC muscle thickness (all p < 0.05).

DISCUSSION: This study showed that sarcopenia is highly prevalent in older adults with dementia (45.7%) than without dementia (11.4%). Amongst different factors, increased age, having low body weight, and the presence of dementia independently increased the risk of sarcopenia diagnosed by GC muscle thickness (but not diagnosed by SMI) in older adults. Thus, we can evaluate easily and successfully the loss of (regional) muscle mass in dementia patients by using US in outpatient clinics.

ABSTRACT

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is one of the most common causes of death worldwide. Therefore, optimizing medical therapy in the comprehensive management of the disease, as well as including pulmonary rehabilitation (PR) in the treatment, is essential. The goal of our study was to determine the impact of PR on the survival of COPD patients.

METHODS: Between 2007-2015, 509 COPD patients who completed the PR constituted the PR group, while 167 patients who applied but could not complete it after the initial evaluations formed the control group. In the PR group, dyspnea perception, exercise capacity, muscle strength, body composition, quality of life, psychosocial status, and i-BODE scores were assessed at the beginning and end of the program, whereas in the control group, these assessments could only be conducted at the beginning. Also, after PR, our PR participants have prescribed a home exercise program, and they were recalled to the hospital at the 3rd, 6th, 12th, 18th, and 24th months for follow-up visits.

RESULTS: A statistically significant improvement was found in almost all the data (except FEV1/FVC, BORG after exercise, and FFMI) after PR. There was a statistically significant difference in 5-year survival in favor of the PR group (p = 0.006), and in PR patients who accompanied the home exercise program vs. those who did not (p = 0.000). Also the gains in MRC (p = 0.003; OR: 2.20; CI: 1.319- 3.682), MEP (p = 0.041; OR: 1.02; CI: 1.001-1.035), and i-BODE (p = 0.006; OR: 0.914; CI: 0.857-0.974) increased the survival.

DISCUSSION: Apart from incorporating PR into treatment in the comprehensive management of COPD, we demonstrated that maintaining a home exercise program for at least two years following PR increased 5-year survival significantly.

ABSTRACT

BACKGROUND: Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) can in vivo characterize tumor microvascular environment. The aim of the present study was to reveal the DCE-MRI findings and to determine the correlation between these findings and immunohistochemical data in head and neck squamous cell carcinoma (HNSCC).

METHODS: Thirty-three patients diagnosed with primary HNSCC were evaluated retrospectively. DCE-MRI was conducted in all cases. CD34, CD105, and ki-67 expressions were analyzed with immunohistochemistry in tissue sections to determine micro-vessel density and proliferative activity.

RESULTS: The DCE-MRI is a successful technique in distinguishing tumor tissue from normal tissue. It was determined that Ve, Ktrans, and ki-67 values were significantly higher in high-stage tumors and there were positive correlations between the Ktrans value (by standard ROI) and CD34 MVDmax and CD34 MVDmean values. No statistically significant correlation was determined between other parameters in DCE-MRI and immunohistochemical data, and T stage.

DISCUSSION: DCE-MRI could successfully differentiate tumor tissue in HNSCC. Furthermore, it was observed that DCE-MRI had the potential to reveal certain immunohistochemical information in vivo.

ABSTRACT

BACKGROUND: Hypertension is a known risk factor for developing atrial fibrillation. However, there is limited data to investigate the association between morning blood pressure surge (MBPS) and paroxysmal atrial fibrillation (PAF). We conducted the present study to determine whether there is a relationship between asymptomatic PAF and MBPS and whether MBPS may be a predictor of asymptomatic PAF episodes.

METHODS: This prospective study comprised 264 adult patients who were newly diagnosed with essential hypertension or were previously diagnosed but not receiving regular antihypertensive therapy. We evaluated the patients in 2 groups according to their 24-h electrocardiography monitoring results: group 1 included patients who exhibited PAF (n = 32, 23 females/9 males; mean age 60.2 ± 7.4 years) and group 2 included patients with no signs of PAF as a control group (n = 232, 134 females/98 males; mean age 56.9 ± 9.4 years). We calculated the MBPS as the difference between mean systolic blood pressure (SBP) in the 2 h after getting up and the minimum nocturnal SBP.

RESULTS: : MBPS values were significantly higher in group 1 than in group 2 (35.3 ± 7.0 vs. 22.0 ± 6.7, p < 0.001). MBPS was positively associated with left atrial diameter (LAD) (r = 0.441, p < 0.001), left ventricle mass index (LVMI) (r = 0.235, p < 0.001), the ratio of early (E) peak of mitral inflow velocity to early (Em) diastolic mitral annular velocity (E / Em) (r = 0.239, p < 0.001), 24-h mean (r = 0.270, p < 0.001) and daytime SBP (r = 0.291, p < 0.001). We determined a cut-off value for MBPS as 28.6 for predicting PAF episodes development and identified LAD and MBPS as independent risk factors for PAF.

DISCUSSION: Patients who had larger MBPS were observed to have higher PAF incidence. MBPS values may be sensitive in predicting asymptomatic episodes of paroxysmal atrial fibrillation.

ABSTRACT

Objective: Data for 2016 from cancer registries were used to estimate cancer incidence and mortality in China in 2016. Methods: According to the quality control process of the National Central Cancer Registry, the data from 683 cancer registries submitted by each province were evaluated, and the data of 487 cancer registries were qualified and included in the final analysis. Age-specific incidence and mortality rates were calculated by area (urban/rural), sex, age and cancer site, combined with national population data to estimate cancer incidence and mortality in China in 2016. Chinese population census in 2000 and Segi’s population were used for age-standardized incidence and mortality rates. Results: Total population covered by 487 cancer registries was 381 565 422 (192 628 370 in urban and 188 937 052 in rural areas). The percentages of morphologically verified (MV%) and death certificate-only cases (DCO%) accounted for 68.31% and 1.40%, respectively, and the mortality to incidence ratio was 0.61. It was estimated about 4 064 000 new cases occurred in China in 2016, with the crude incidence rate being 293.91/100 000 (the rates of males and females were 315.52/100 000 and 271.23/100 000), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 190.76/100 000 and 186.46/100 000, with the cumulative incidence rate (0-74 years old) being 21.42%. The crude incidence and ASIRC were 314.74/100 000 and 196.38/100 000 in urban areas, whereas in rural areas, they were 265.90/100 000 and 182.21/100 000, respectively. It was estimated about 2 413 500 cancer deaths occurred in China in 2016, the crude mortality rate was 174.55/100 000 (216.16/100 000 in males and 130.88/100 000 in females), the age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 106.00/100 000 and 105.19/100 000, and the cumulative mortality rate (0-74 years old) was 11.85%. The crude mortality and ASMRC were 180.31/100 000 and 104.44/100 000 in urban areas, whereas in rural areas, they were 166.81/100 000 and 108.01/100 000, respectively. The most common cancer cases include lung, colorectal, stomach, liver and female breast cancers. The top five cancers accounted for about 57.27% of all cancer cases. The most common cancer deaths included lung, liver, stomach, colorectal and esophageal cancers. The top five cancers accounted for about 69.25% of all cancer deaths. Conclusions: The burden of cancer shows a continuous increasing trend in China. Regional and gender differences in cancer burden are obvious. The cancer patterns still show the coexistence of cancer patterns in developed countries and developing countries. The situation of cancer prevention and control is still serious in China.

ABSTRACT

Probabilistic sequence learning supports the development of skills and enables predictive processing. It remains contentious whether visuomotor sequence learning is driven by the representation of the visual sequence (perceptual coding) or by the representation of the response sequence (motor coding). Neurotypical adults performed a visuomotor sequence learning task. Learning occurred incidentally as it was evidenced by faster responses to high-probability than to low-probability targets. To uncover the neurophysiology of the learning process, we conducted both univariate analyses and multivariate pattern analyses (MVPAs) on the temporally decomposed EEG signal. Univariate analyses showed that sequence learning modulated the amplitudes of the motor code of the decomposed signal but not in the perceptual and perceptual-motor signals. However, MVPA revealed that all 3 codes of the decomposed EEG contribute to the neurophysiological representation of the learnt probabilities. Source localization revealed the involvement of a wider network of frontal and parietal activations that were distinctive across coding levels. These findings suggest that perceptual and motor coding both contribute to the learning of sequential regularities rather than to a neither-nor distinction. Moreover, modality-specific encoding worked in concert with modality-independent representations, which suggests that probabilistic sequence learning is nonunitary and encompasses a set of encoding principles.

ABSTRACT

INTRODUCTION: Centralisation defined as the reorganisation of healthcare services into fewer specialised units serving a higher volume of patients is a potential measure for healthcare reforms aiming at reducing costs while improving quality. Research on centralisation of healthcare services is thus essential to inform decision-makers. However, so far studies on centralisation report a variability of outcomes, often neglecting outcomes at the health system level. Therefore, this study aims at developing a core outcome set (COS) for studies on centralisation of hospital procedures, which is intended for use in observational as well as in experimental studies.

METHODS AND ANALYSIS: We propose a five-stage study design: (1) systematic review, (2) focus group, (3) interview studies, (4) online survey, (5) Delphi survey. The study will be conducted from March 2022 to November 2023. First, an initial list of outcomes will be identified through a systematic review on reported outcomes in studies on minimum volume regulations. We will search MEDLINE, EMBASE, CENTRAL, CINHAL, EconLIT, PDQ-Evidence for Informed Health Policymaking, Health Systems Evidence, Open Grey and also trial registries. This will be supplemented with relevant outcomes from published studies on centralisation of hospital procedures. Second, we will conduct a focus group with representatives of patient advocacy groups for which minimum volume regulations are currently in effect in Germany or are likely to come into effect to identify outcomes important to patients. Furthermore, two interview studies, one with representatives of the German medical societies and one with representatives of statutory health insurance funds, as well as an online survey with health services researchers will be conducted. In our analyses of the suggested outcomes, we will largely follow the categorisation scheme developed by the Cochrane EPOC group. Finally, a two-round online Delphi survey with all stakeholder groups using predefined score criteria for consensus will be employed to first prioritise outcomes and then agree on the final COS.

ETHICS AND DISSEMINATION: This study has been approved by the Research Ethics Committee at the Brandenburg Medical School Theodor Fontane (MHB). The final COS will be disseminated to all stakeholders involved and through peer-reviewed publications and conferences.
