Published: August 2022

Objective To compare the clinical outcomes between single-port laparoscopic appendectomy using a needle-type grasping forceps (SLAN) and conventional three-port laparoscopic appendectomy (CLA) for patients with uncomplicated appendicitis. Methods We retrospectively collected clinical data of patients with uncomplicated appendicitis who underwent SLAN or CLA from May 2019 to May 2021 in our center. The patients’ baseline characteristics, perioperative outcomes, and follow-up data were compared between the two groups. Additionally, baseline characteristics were compared with postoperative outcomes in the SLAN group. Results Ninety-six patients were enrolled (SLAN group, n = 32; CLA group, n = 64). The SLAN group had a shorter hospital stay, lower 24-hour postoperative visual analogue scale scores, shorter postoperative fasting time, lower frequency of antibiotic administration, and longer operative time than the CLA group. In the SLAN group, younger patients had a longer appendix and male patients had a thicker appendix; additionally, patients with an appendiceal diameter of 0.6 to 1.0 cm had a longer postoperative hospital stay and higher frequency of antibiotic administration. Conclusions Compared with CLA, SLAN may be less invasive, provide faster postoperative recovery, and result in better cosmesis for patients with uncomplicated appendicitis. Further research should be performed to evaluate the long-term outcomes.

As a theoretically rigorous and accurate method, FEP-ABFE (Free Energy Perturbation-Absolute Binding Free Energy) calculations showed great potential in drug discovery, but its practical application was difficult due to high computational cost. To rapidly discover antiviral drugs targeting SARS-CoV-2 M pro and TMPRSS2, we performed FEP-ABFE–based virtual screening for ∼12,000 protein-ligand binding systems on a new generation of Tianhe supercomputer. A task management tool was specifically developed for automating the whole process involving more than 500,000 MD tasks. In further experimental validation, 50 out of 98 tested compounds showed significant inhibitory activity towards M pro, and one representative inhibitor, dipyridamole, showed remarkable outcomes in subsequent clinical trials. This work not only demonstrates the potential of FEP-ABFE in drug discovery but also provides an excellent starting point for further development of anti-SARS-CoV-2 drugs. Besides, ∼500 TB of data generated in this work will also accelerate the further development of FEP-related methods.

Objective: To determine the prevalence of drug-related problems and the factors influencing them among adult psychiatric inpatients. Methods: A multi-centre cross-sectional observational study was conducted from April to July 2021 at five randomly selected hospitals in Northwest Ethiopia. A total of 325 consecutively sampled patients participated in the study. Clinical pharmacists assessed the drug-related problems based on clinical judgement supported by updated evidence-based disease guidelines. We used the Medscape drug-interactions checker to check drug-to-drug interactions. The results were summarised using descriptive statistics, including frequency, mean, and standard deviation. For each variable, an odds ratio with a 95% confidence interval was calculated, as well as the related p-value. The value of p ⩽ 0.05 was considered statistically significant. Results: From the total number of 325 study participants, more than half of them (52.9%) were females, and the mean age ± (standard deviation) was 30.8 ± 11.3 years. At least one drug-related problem was recorded by 60.9% to 95% confidence interval (55.7–65.8) of study participants, with a mean of 0.6 ± 0.49 per patient. Additional drug therapy was the most common drug-related problem (22.8%) followed by non-adherence to medicine (20.6%) and adverse drug reactions (11%), respectively. Factors independent associated with drug-related problems were rural residence (adjusted odds ratio = 1.96, 95% confidence interval: 1.01–2.84, p-value = 0.046), self-employed (adjusted odds ratio = 6.0, 95% confidence interval: 1.0–36.9, p-value = 0.035) and alcohol drinkers (adjusted odds ratio = 6.40, 95% confidence interval: 1.12–37.5, p-value = 0.034). Conclusion: The prevalence of drug-related problems among adult psychiatric patients admitted to psychiatric wards was high. Healthcare providers give more attention to tackling these problems. Being a rural resident, self-employed, and alcohol drinkers were associated with drug-related problems.

Published: August 2022

Introduction Providing care for patients by family caregivers causes in several consequences known as “Caregiving Burden”, which affects the caregiver's health and the whole family process, considered in holistic healthcare/nursing. This study aimed to evaluate the caregiving burden and social support in family caregivers of patients with cancer and their influencing factors in a local area in Iran. Methods In this cross-sectional study, 190 family members of patients with cancer were studied through convenient sampling method. Data were collected using demographic data sheet enriched with Karnofsky Performance Status Scale and Katz Index of Independence in Activities of Daily Living (ADL), and Zarit Burden Inventory and Medical Outcomes Social Support Survey questionnaires. Results The results indicated intermediate performance status and moderate independence in ADL in patients. The mean score of caregiving burden was 43.95 ± 17.48 which indicates moderate to severe burden. The average social support in the caregivers was 60.25 ± 23.81% which shows above the average social support. Both performance status and dependence in ADL of patient had statistically significant effect on the caregiving burden in caregivers. Also a statistically significant negative relationship was observed between caregiving burden and social support in primary family caregivers of patients with cancer. Discussion Considering the increasing importance of primary care provided by families, developing strategies for providing caregiver's needs through family care in cancer nursing is essential. So supporting caregivers through family nursing in holistic healthcare by providing social support, can play a significant role in reducing caregiving burden in healthcare services considering the qualified holistic healthcare/nursing.
Blue growth zones caused by Fe2+ in tourmaline crystals from the San Piero in Campo gem-bearing pegmatites, Elba Island, Italy

Published: August 2022

AbstractTwo tourmaline crystals with a blue growth zone at the analogous pole, respectively from the San Silvestro and the Fucili pegmatites, located in the San Piero in Campo village, Elba Island (Tyrrhenian Sea, Italy), have been described for the first time using compositional and spectroscopic data to define their crystal-chemical aspects and the causes of the colour. Compositional data obtained by electron microprobe analysis indicate that both tourmalines belong to the elbaite–fluor-elbaite series. The upper part of each crystal is characterised by an increased amount of Fe (FeO up to ~1 wt.%) and a Ti content below the detection limit. Optical absorption spectra recorded on the blue zone of both samples show absorption bands caused by spin-allowed d-d transitions in [6]-coordinated Fe2+, and no intervalence charge transfer Fe2+-Ti interactions, indicating that Fe2+ is the only chromophore. Mössbauer analysis of the blue zone of the Fucili sample confirmed the Fe2+ oxidation state, implying that the redox conditions in the crystallisation environment were relatively reducing. The presence of colour changes at the analogous termination during tourmaline crystal growth suggests a change in the composition of the crystallisation environment, probably associated with a partial opening of the system.
The role of iron in chronic inflammatory diseases: from mechanisms to treatment options in anemia of inflammation
Authors: Marques Oriana , Weiss Günter , Muckenthaler Martina U. 
Published: August 2022

AbstractAnemia of inflammation (AI) is a highly prevalent comorbidity in patients affected by chronic inflammatory disorders, such as chronic kidney disease, inflammatory bowel disease, or cancer, that negatively affect disease outcome and quality of life. The pathophysiology of AI is multifactorial, with inflammatory hypoferremia and iron-restricted erythropoiesis playing a major role in the context of disease-specific factors. Here, we review the recent progress in our understanding of the molecular mechanisms contributing to iron dysregulation in AI, the impact of hypoferremia and anemia on the course of the underlying disease, and (novel) therapeutic strategies applied to treat AI.
Plating versus elastic stable intramedullary nailing for displaced pediatric midshaft clavicular fractures
Authors: Hong Pan , Liu Ruikang , Rai Saroj , Ze Renhao , Tang Xin , Li Jin 
Published: August 2022

Abstract
Introduction
Traditionally, operative treatment for displaced midshaft clavicle fractures in adolescents has been achieved by using a plate and screws. However, a minimally invasive trend has led surgeons to use the elastic stable intramedullary nail (ESIN) for displaced midshaft clavicle fractures. This study aims to compare the clinical outcomes of adolescent patients who were operated on with an ESIN vs. a plate.

Methods
All patients aged between 10 and 14 years with displaced midshaft clavicle fractures who were operated on at our institute between January 2014 and January 2018 were reviewed retrospectively. The preoperative data, including baseline information on the patients, and types of surgical procedure were collected from the hospital database. The postoperative data, including clinical outcome and complications, were collected during the follow-up visits. Clinical outcome was evaluated during outpatient visits using the American Shoulder and Elbow Surgeons (ASES) score. The scar problem was evaluated according to the Scar Cosmesis Assessment and Rating (SCAR) scale.

Results
A total of 73 patients were included. Patients were categorized into two groups: ESIN (n = 45; 27 males, 18 females) and plate (n = 28; 17 males, 11 females), according to surgical technique. The average age of the patients in the ESIN group was 12.2 ± 1.5 years, and that in the plate group was 12.2 ± 1.4 years. The ESIN group presented significantly less operative time (31.1 vs. 59.8 min), a shorter hospital stay (1.5 vs. 2.5 days), and a smaller incision (2.4 vs. 5.4 cm) as compared to the plate group (P < .001). The rate of scar concern was much higher in the plate group (71.4%) than the ESIN group (22.2%) (P < .001). There was no statistically significant difference in shoulder function between the ESIN group and the plate group at different time points.

Conclusion
A conservative approach remains the first choice for a pediatric clavicle fracture. Both the ESIN and the plate are safe and effective treatment methods for displaced midshaft clavicle fractures in adolescents. The ESIN is superior to the plate given its shorter operative time, shorter hospital stay, lower rate of scar concern, and easier implant removal.

Authors: Migliorini Filippo , Eschweiler Jörg , Spiezia Filippo , Knobe Matthias , Hildebrand Frank , Maffulli Nicola 
Published: August 2022

Abstract
Background
This systematic review investigates the role of synthetic graft for primary medial patellofemoral ligament (MPFL) reconstruction in patients with recurrent patellofemoral instability, focusing on clinical scores and the rate of complications.

Methods
This systematic review was conducted according to the PRISMA statement. The main online databases were accessed in January 2022 without time constraints. All clinical studies investigating the use of synthetic grafts for MPFL reconstruction were accessed. Revision settings were not considered. Only articles reporting data on patients with recurrent patellofemoral instability were eligible. Studies regarding congenital or acute patellofemoral dislocation were excluded. Only studies performing a follow-up longer than 24 months were considered.

Results
Data on 199 patients [mean age 22.3 (range 19.0–28.0) years] were collected. The mean follow-up was 60.5 (39.0–142.8) months. All the scores of interest improved at last follow-up: Kujala (+ 24.8; P = 0.0002), Lysholm (+ 42.0; P = 0.02), Tegner (+ 1.2; P = 0.03), IKDC (+ 20.9; P = 0.02). Post-operatively, a positive apprehension test was detected in 6.1% (7/115) of patients, and a sensation of instability was reported by 1.5% (3/199) of patients. The rate of re-dislocations was 2.5% (5 of 199 patients), and revision procedures were performed in less than 1% (1 of 199) of patients.

Conclusion
Synthetic graft may be reliable and feasible for primary MPFL reconstruction in patients with recurrent patellofemoral instability.
Production of extracellular amylase contributes to the colonization of Bacillus cereus 0–9 in wheat roots
Authors: Huang Qiubin , Liu Huiping , Zhang Juanmei , Wang Shaowei , Liu Fengying , Li Chengdie , Wang Gang 
Published: August 2022

Abstract
Background
Bacteria usually secrete a variety of extracellular enzymes to degrade extracellular macromolecules to meet their nutritional needs and enhance their environmental adaptability. Bacillus cereus 0–9, a biocontrol bacterial strain isolated from wheat roots, has three genes annotated as encoding amylases in the genome, but their functions are unknown, and whether they are involved in the colonization process of the bacterium remains to be further studied.

Methods
Mutant gene strains and fluorescently tagged strains were constructed by homologous recombination, and amylase protein was expressed in the prokaryotic Escherichia coli BL21(DE3) expression system. The iodine staining method was used to measure the activity of amylase proteins. We further observed the colonization abilities of the test strains in wheat roots through frozen section technology.

Results
The results showed that there were three amylase-encoding genes, amyC, amyP and amyS, in the B. cereus 0–9 genome. Among the three amylase encoding genes, only amyS produced extracellular amylase whose secretion was related to signal peptide at position 1–27. The AmyS protein encoded by the amyS gene is an α-amylase. The growth of Rhizoctonia cerealis was inhibited 84.7% by B. cereus 0–9, but the biocontrol ability of the ΔamyS strain decreased to 43.8% and that of ΔamyS/amyS was restored when the amyS gene was complemented. Furthermore, the biocontrol ability of the ΔamySec strain was decreased to 46.8%, almost the same as that of the ΔamyS mutant. Due to the deletion of the amyS gene, the colonization capacities of ΔamyS (RFP) and ΔamySec (RFP) in wheat roots decreased, while that of ΔamyS/amyS (RFP) was restored after the amyS gene was complemented, indicating that the amyS gene influences the colonization of B. cereus 0–9 in wheat roots. In addition, the colonization and biocontrol abilities of the mutant were restored after the addition of sugars, such as glucose and maltose.

Conclusions
B. cereus 0–9 encodes three genes annotated as amylases, amyC, amyP and amyS. Only the deletion of the amyS gene with a signal peptide did not produce extracellular amylase. The AmyS protein encoded by the amyS gene is an α-amylase. Our results indicated that the amyS gene is closely related to the colonization abilities of B. cereus 0–9 in wheat roots and the biocontrol abilities of B. cereus 0–9 to fight against R. cerealis. The extracellular amylase produced by B. cereus 0–9 can hydrolyze starch and use glucose, maltose and other nutrients to meet the needs of bacterial growth. Therefore, it is very possible that the secretion and hydrolytic activities of extracellular amylase can promote the colonization of B. cereus 0–9 in wheat roots and play important roles in the prevention and control of plant diseases. Our results contribute to exploring the mechanisms of microbial colonization in plant roots.
Longitudinal changes of mental health problems in children and adolescents treated in a primary care-based health-coaching programme – results of the PrimA-QuO cohort study
Authors: Decke Siona , Hamacher Karina , Lang Martin , Laub Otto , Schwettmann Lars , Strobl Ralf , Grill Eva 
Published: August 2022

Abstract
Background
In Germany, 19.1% of boys and 14.5% of girls are affected by mental health problems (MHP). Paediatricians are usually the first in line to be contacted but they often do not feel adequately trained to diagnose and treat MHP in primary care. A major statutory health insurance fund introduced a health coaching (HC) programme to strengthen primary care consultation for MHP. The HC includes a training concept for paediatricians, standardised guidelines for actions and additional payments. The aim of this study was to investigate the potential effects of the HC programme on the change of MHP in children and adolescents.

Methods
A prospective cohort study was conducted in Bavaria, Germany, in 2018 and 2019. Data were collected at 2 points 1 year apart using an online questionnaire. Parents of patients with developmental disorder of speech and language, head/abdominal pain, conduct disorder or non-organic enuresis were approached by their health insurance. Families treated according to the HC programme form the intervention group while all others serve as controls. MHP was assessed using the Strengths and Difficulties Questionnaire (SDQ) as a child self-assessment (SDQ-S)/or external assessment by parents (SDQ-P). Determinants of SDQ total score were analysed using linear mixed effects models.

Results
Cross-sectional (n = 1090) and longitudinal analyses (n = 599) were performed. At baseline, a total of 23.5% had an SDQ total score “at risk” (SDQ-S > 15/SDQ-P > 13). There were no significant differences between intervention and controls. After full adjustment for all potential confounders, higher SDQ scores indicating more problems were significantly associated with male sex (2.000, p < 0.001) whereas a high parental education level was significantly associated with decreased SDQ scores (-2.127, p =0.034). There was a significant improvement in the control group over time (-0.814, p = 0.001) while the SDQ scores in the intervention group remained stable (-0.012, p = 0.020).

Conclusion
This evaluation of the HC programme could not prove a clinically relevant intervention’s effect on the MHP developmental course. Nevertheless, (HC) paediatricians have crucial potential to improve the care of MHP patients. Targeting families with less access to support measures might help reduce the burden of MHP and be a step towards continuous improvement of care.
Are self-management abilities beneficial for frail older people’s cognitive functioning?
Authors: Cramm Jane M. , Nieboer Anna P. 
Published: August 2022

Abstract
Background
Self-management abilities seem to be important for the cognitive functioning of older people, especially those who are frail. We investigated relationships between broad self-management abilities (initiative taking, investment behavior, resource variety, resource multifunctionality, self-efficacy, and positive frame of mind) and cognitive functioning among frail older people while controlling for background characteristics (sex, age, marital status, and educational level).

Method
Survey data were collected from mid-2014 to mid-2015 from community-dwelling frail older people residing in North Brabant, the Netherlands. We measured cognitive functioning with the 12-item Mini-Mental State Examination (MMSE-12) and self-management abilities with the short version of the Self-Management Ability Scale (SMAS-S).

Results
In total, 588 of 834 potential participants were willing to participate (70.5% response rate). The mean age was 82.33 ± 5.19 and the majority (68.5%) of respondents were female. About one-third (38.4%) of respondents had low educational levels and 61.7% lived alone. Mean MMSE-12 and SMAS-S scores were 9.68 ± 2.10 and 3.70 ± 0.88, respectively. Bivariate analyses showed that all six self-management abilities were related positively to cognitive functioning. Multivariate analyses with adjustment for background characteristics (sex, age, marital status, and educational level) showed that cognitive functioning was associated positively with initiative taking (β = 0.23, p = 0.030) and investment behavior (β = 0.24, p = 0.030) among community-dwelling frail older people.

Conclusions
This study clearly showed that a repertoire of broad self-management abilities is related to cognitive functioning among community-dwelling frail older people. Initiative taking and investment behavior seem to be especially important. These findings are of interest in a time of populational aging and an increasing number of older people dealing with cognitive problems. Preventive investments in (older) people’s self-management abilities are expected to be beneficial for their cognitive functioning in the long term.
Circulating miR-130a-3p is elevated in patients with cerebral atherosclerosis and predicts 2-year risk of cerebrovascular events
Authors: Xu Jialei , Gao Fengchao 
Published: August 2022

AbstractBackgroundCerebral atherosclerosis (AS) leads to high risk of cerebrovascular events. This study aims to evaluate the diagnostic performance of serum microRNA-130a-3p (miR-130a-3p) in cerebral AS patients, and construct a logistic risk model for 2-year cerebrovascular events on the basis of the prognostic potential of miR-130a-3p.MethodsSerum samples were collected from 74 cerebral AS patients and 62 control individuals, and miR-130a-3p expression was investigated using reverse transcription quantitative PCR. Risk factors related with cerebral AS were assessed using a logistic regression analysis, and the receiver operating characteristic analysis was performed to evaluate the diagnostic value of miR-130a-3p. The relationship between miR-130a-3p and cerebrovascular events was analyzed using a Kaplan–Meier method, and a logistic risk model was constructed for 2-year cerebrovascular events.ResultsCerebral AS patients had elevated serum miR-130a-3p compared with controls (P < 0.001). Serum miR-130a-3p had diagnostic value (AUC = 0.899), and could significantly improve the diagnostic accuracy of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in cerebral AS patients (AUC = 0.992). High serum miR-130a-3p was independently related with high probability of cerebrovascular events (HR = 1.993, 95% CI = 1.205–2.897,P = 0.006), and a logistic risk model was constructed based on serum miR-130a-3p, hs-CRP, TC and LDL-C.ConclusionAll the findings indicated that high serum miR-130a-3p had diagnostic potential to screen cerebral AS, and predicted the probability of cerebrovascular events after AS. The logistic risk model based on miR-130a-3p may provide an efficient method to predict 2-year cerebrovascular events in AS patients.
