Are functional gastrointestinal disorders a clinically significant comorbid factor for acute respiratory infection in children?
Authors: Meskina E. R. , Khadisova M. K. 
Published: April 2020

Rationale: Functional gastrointestinal disorders (FGID) are highly prevalent in children worldwide. Current concept of FGID pathophysiology implies contributions from various mechanisms. Information in the role of acute respiratory infections in the development of FGID in children is lacking.Aim: To determine the prevalence of FGID in children hospitalized to the department of infectious diseases with acute respiratory tract infections (ARTI) and their association with demographic, medical biological factors and clinical manifestations.Materials and methods: We performed observational and cross-sectional study with continuous patient sampling. The study included 180 ARTI patients, whose mothers agreed to fill in the proposed questionnaire of 41 items. The diagnosis of FGID during in-hospital stay was made based on clinical data in accordance with the Rome criteria IV (2016) and by standard collection of the information from the parents. The stool characteristics were assessed with the Bristol scale. The rate of recurrent ARTI was assessed by the resistance index of above 0.5. We considered clinical symptoms of ARTI at the admittance, the rates of bacterial complications and the need in antibacterial treatment.Results: The prevalence of FGID in hospitalized children with ARTI below 4 years of age (n = 134) was 35.1% (95% confidence interval [CI]) 27.0– 43.9); they had higher rates of functional diarrhea (14.9%, 95% CI 9.4–22.1) and constipation (14.2%, 95% CI 8.8–21.3). Among those above 4 years of age (n = 46), FGID were diagnosed in 50% (95% CI 34.9–65.1) of the cases; with most frequent symptoms being abdominal pain (39.1%, 95% CI 25.1–54.6) and irritable bowel syndrome (10.8%). Irrespective of their age, the children with FGID had higher rates of ARTI recurrence (by 34.0%, 95% CI 20.0–48.1; relative risk 1.98, 95% CI 1.47–2.69; odds ratio 4.13, 95% CI 2.18–7.85) and intestinal infections in their past history, compared to those without any gastrointestinal symptoms during the index hospitalization. In children with FGID, ARTI were more frequently complicated by otitis and they had higher requirement in antibiotics. The mothers of the infants and toddlers with FGID had lower educational level (smaller proportion of those with high school education) and were less satisfied with their home and living conditions, whereas their fathers were older and more frequently employed in vehicle operations and less frequently were occupied in communication-related professions.Conclusion: Acute respiratory infections, especially recurring, may plaу a significant role in the development and maintenance of FGID in children. Further studies are necessary, which may result in useful information for the development of tailored strategies to treatment and prevention.

Published: April 2020

Introduction: Portugal is experiencing the effects of the COVID-19 pandemic since March 2020. All-causes mortality in Portugal increased during March and April 2020 compared to previous years, but this increase is not explained by COVID-19 reported deaths. The aim of this study was to analyze and consider other criteria for estimating excessive all-causes mortality during the early COVID-19pandemic period.Material and Methods: Public data was used to estimate excess mortality by age and region between March 1 and April 22, proposing baselines adjusted for the lockdown period.Results: Despite the inherent uncertainty, it is safe to assume an observed excess mortality of 2400 to 4000 deaths. Excess mortality was associated with older age groups (over age 65).Discussion: The data suggests a ternary explanation for early excess mortality: COVID-19, non-identified COVID-19 and decrease in access to healthcare. The estimates have implications in terms of communication of non-pharmaceutical actions, for research, and to healthcare professionals.Conclusion: The excess mortality occurred between March 1 and April 22 was 3.5- to 5-fold higher than what can be explained by the official COVID-19 deaths.

The research purpose: to study features of clinical process of a coronary heart disease when it combines with a bronchial asthma.The materials and methods: 180 people were included in the research, 90 of them suffer from both CHD and BA (the first group), and also 90 people have only CHD without BA (the second group). The examination included complaint collection process, studying medical history, medical examination, percussion, auscultation, blood pressure measurement with the Korotkov’s method twice a day (in the morning and in the evening), heart rate measurement, 24-hour Holter ECG monitoring, echodoplercardiography. Besides, standard laboratory biochemical testing, including total cholesterol and lowdensity lipoprotein cholesterol, were made with the enzymatic colorimetric method.The results. Dyspnoea is the main complaint among 86 patients with both CHD and asthma, humans have (95,5%), moreover, dyspnoea combines with heartbeating in 73,8%, and is accompanied by angina pectoris only in 20%. There is a significant difference between systolic and diastolic blood pressure (р=0,001) that becomes higher if CHD combines with asthma. The signs of left ventricular and interventricular septum hypertrophy were discovered in the first group, these signs statistically significantly differ from the ones in the second group. The medium pulmonary arterial pressure is significantly higher in the combined group than in the group with only CHD (р=0,001). It is revealed with 24-hour Holter ECG monitoring that cases of myocardial ischemia are more frequent in the group which consists of patients with CHD. Besides, duration of ischemic depression per day is longer in this group too. It might be that if patients have both CHD and asthma they do not reach an ischemic threshold because of dyspnoea due to a respiratory failure.The conclusion. According to our findings bronchial asthma occurs among patients with coronary heart disease in 16.6% of cases. It is a distinctive feature of a bronchial asthma associated with coronary heart disease, that a patient often complaints to dyspnea (cardiopulmonary) and palpitation, increase in arterial blood pressure and heart rate, which appropriately indicates the activation of rennin-angiotensin-aldosteron and sympathicoadrenal systems. It requires the inclusion of appropriate drug groups in the treatment of patients.

Comme toute activité d’élevage, la production porcine est à l’origine d’effluents qui peuvent avoir un impact sur l’environnement parce qu’ils affectent la qualité de différentes ressources naturelles comme l’air, l’eau, le sol et la santé humaine. Le programme «Porcherie verte» s’est plus particulièrement attaché à un certain nombre de composés présents dans l’alimentation du porc dont une fraction, non retenue par l’animal, est rejetée dans les déjections. Le devenir de ces composés tout au long de la chaîne de production, de l’aliment du bétail au sol, varie beaucoup en fonction des filières utilisées pour la gestion des effluents.
Dans l’esprit du public, les nuisances olfactives sont également très liées à la production porcine. Souvent considérées comme un facteur limitant essentiel au développement de cet élevage, elles dépendent aussi très largement des filières utilisées pour la gestion des effluents.

Treatment of Proximal Femoral Fragility Fractures in Patients with COVID-19 During the SARS-CoV-2 Outbreak in Northern Italy
Authors: Catellani Francesco , Coscione Andrea , D’Ambrosi Riccardo , Usai Luca , Roscitano Claudio , Fiorentino Gennaro 
Published: April 2020

Background:
From February 20 to April 2020, the coronavirus SARS (severe acute respiratory syndrome)-CoV-2 spread in northern Italy, drastically challenging the care capacities of the national health care system. Unprepared for this emergency, hospitals have quickly reformulated paths of assistance in an effort to guarantee treatment for infected patients. Orthopaedic departments have been focused on elderly traumatology, especially the treatment of femoral neck fractures in patients with coronavirus disease-2019 (COVID-19). The purpose of the present study was to evaluate the orthopaedic management strategy for femoral fragility fractures in COVID-19-positive patients with the hypothesis that operative treatment may contribute to the overall stability of the patient.

Methods:
Sixteen patients affected by proximal femoral fracture and a recent history of fever, shortness of breath, and desaturation were admitted to the emergency room. Thoracic computed tomography (CT) and oropharyngeal swabs confirmed that they were positive for COVID-19, requiring hospitalization and prophylaxis with low-molecular-weight heparin.

Results:
Three patients died before surgery because of severe respiratory insufficiency and multiple-organ-failure syndrome. Ten patients underwent surgery on the day after admission, whereas 3 patients had suspended their use of direct thrombin inhibitors and needed surgery to be delayed until the third day after admission. In all patients except 1, we noted an improvement in terms of O2 saturation and assisted respiration. In 9 patients, hemodynamic and respiratory stability was observed at an average of 7 days postoperatively. Four patients who underwent surgical treatment died of respiratory failure on the first day after surgery (1 patient), the third day after surgery (2 patients), or the seventh day after surgery (1 patient).

Conclusions:
We noted a stabilization of respiratory parameters in 12 COVID-19-positive patients who underwent surgery treatment of proximal femoral fractures. We believe that in elderly patients with COVID-19 who have proximal femoral fractures, surgery may contribute to the overall stability of the patient, seated mobilization, improvement in physiological ventilation, and general patient comfort in bed.

Authors: Liu Bin , Gao Pengxiang , Zhang Shuoxin 
Published: April 2020

Abstract
Background:Agroforestry system is regarded as a promising practice in sustainable agricultural management. However, the effects of long-term tree-based intercropping on crop remain poorly understood, especially in the Loess Plateau. In this study, the impacts of photosynthetic and respiration rate were determined by the portable photosynthesis system (Li-6400), and the effects of the root growth dynamics of soybean in walnut-soybean intercropping system were measured by soil auger and WinRHIZO root analysis system, in the Loess Plateau. Results:The results showed that soybean reached the highest net photosynthetic rate during flowering period, with the net photosynthetic rate of intercropped soybean, which was 20.40µmol·m-2·s-1, significantly higher than that of its monocropped counterpart. Soybean biomass reached the maximum during the pod-bearing period, with intercropped soybean biomass being 25.49g, significantly higher than that of its monocropped counterpart. The mean diameter and increased density of soybean fine roots reduced along with increased soil depth. Both the diameter (0.43mm) and increased density (930cm/dm3) of intercropped soybean fine roots were evidently higher than those of monocropped soybean(0.35mm, 780cm/dm3). With increasing cropping years, fine roots of intercropped soybean tended to be mainly distributed in soil at a depth between 0 and 20cm from the fifth year. Conclusion:Collectively, compared with soybean monoculture, walnut soybean agroforestry system is more conducive to soybean growth in the Loess Plateau.

Abstract
Background Pupfish frequently enter paradoxical anaerobism in response to endogenously produced or exogenously supplied ethanol in a dose-dependent manner. To decipher the role of the gut microbiota in ethanol-associated paradoxical anaerobism, gut microbial communities were depleted using a cocktail of antibiotics and profiled using 16S rRNA gene sequencing. Results Compared to the control group (n=12), microbiota-depleted fish (n=12) spent more time in paradoxical anaerobism. Our analysis indicated that the bacterial phyla Proteobacteria, Fusobacteria, Bacteroidetes, Firmicutes, Actinobacteria, Patescibacteria, and Dependentiae dominated the pupfish gut, which is consistent with other fish gut microbiota. Although the gut microbial communities with and without antibiotic treatment were similarly diverse, they were distinct and the greatest contribution to the dissimilarity (27.38%) was the common fish commensal Cetobacterium. Conclusions This study reports the first characterization of gut microbial communities of pupfish and suggests the microbiome may play a critical role in regulating metabolic strategies that are critical for survival in extremes of temperature and oxygen concentration. We speculate that Cetobacterium, a primary fermenter, also consumes ethanol through secondary fermentation via an alcohol dehydrogenase and therefore regulates the transition from paradoxical anaerobism to aerobic respiration in fish. Given the wide distribution and abundance of Cetobacterium in warm-water fishes, this process may be of broad importance, and suggests that the microbiome be carefully considered for both conservation and aquaculture.

Abstract
Background: Through the comparison of three-dimensional CT reconstruction between the supine position and the prone position, the relative position of thoracolumbar great vessels and vertebral body was studied, and the shortest safe distance between them was measured to improve the safety of bicortical pedicle screw insertion and reduce the risk of vascular injury. Methods: Forty adults were selected to participate the research. Three-dimensional reconstruction of thoracolumbar (T9-L3) CT was performed in the prone position and the supine position. The relative distance between the Aorta/Inferior Vena Cava (IVC) and vertebral body was obtained as AVD/VVD respectively. The relative angle of the Aorta/ IVC and the vertebral body was calculated as ∠AOY/∠VOY. Self-controlled experiments were carried out in the prone and the supine positions, and the data obtained were analyzed using SPSS 22.0 statistical software. Results: The AVD of the prone position and the supine position was the shortest at T12 (3.18 ±0.68mm), but the difference was not statistically significant. The aorta of the T9-L3 segment was shifted from the anterolateral to the anteromedial. The ∠AOY of the other groups differed significantly between the prone and supine positions in all vertebrae except L1 (P < 0.05), and the aorta in the prone position was more anteromedial than that of supine position. With regard to VVD/∠VOY, there was no significant difference between the prone and supine positions (P≥0.05), and the minimum VVD of L3 segment is greater than 5.4mm. The IVC has no obvious mobility and is fixed in the range of 20 °~ 30 ° near the midline. Conclusion: When using bicortical anchoring of pedicle screws, it is safe to ensure that the protruding tips of the screw is less than 3mm. Due to the mobility of the aorta in different postures and individual differences in anatomy, the prone position CT can help doctors to make better preoperative plans and decisions.
What is the role of the Practice Nurse in the care of people living with dementia, or cognitive impairment, and their support person(s)? : A systematic review.
Authors: Gibson Caroline , Goeman Dianne , Pond Dimity 
Published: April 2020

Abstract
Background: The potential value of expanding the Practice Nurse role to include the recognition and management of dementia has been acknowledged and Practice Nurses are well-positioned to provide comprehensive dementia information and support so that people living with dementia are better equipped to self-manage their health and live well with dementia. The purpose of this review was to systematically examine published Australian and international literature to identify the existing and potential roles of Practice Nurse’s involvement in the delivery of care to people living with dementia or cognitive impairment and their support person(s) and also describe the characteristics and effectiveness of nurse interventions in dementia models of care in general practice. Methods: We systematically reviewed the evidence for roles and characteristics of the Practice Nurse in the delivery of dementia care. A comprehensive literature search identified relevant original research published in English between January 2000 and January 2019 and available in full text. Thirteen articles were included. Results: Characteristics of roles, undertaken by nurses working in the general practice setting, which were potentially beneficial to people living with dementia and their support person were identified. These included increased patient accessibility to the Practice Nurse, early recognition and management of cognitive changes, care management and collaboration with the General Practitioner. Limitations of the provision of dementia care by Practice Nurses included a lack of definition of the role, inadequate dementia specific training, time constraints and poor communication with General Practitioners. Conclusions Further research is required to define and evaluate the scope of practice and characteristics of the Practice Nurse role in dementia care provision. Embedding in usual general practice care an evidence-based model of care describing the role of the Practice Nurse in dementia care provision has the potential to increase early recognition of cognitive impairment and more appropriate primary care management of dementia.

Abstract
Background : Several studies have shown that maternal HIV infection is associated with adverse pregnancy outcomes such as low birth weight and perinatal mortality. However, the association is conflicted with the effect of antiretroviral therapy (ART) on the pregnancy outcomes and it remains unexamined. Using methods for matching possible confounders, the objectives of the study were to assess the effect of maternal HIV on birth weight and perinatal mortality and to investigate the effect of ART on these two pregnancy outcomes in HIV-infected women.

Methods: Data on 4111 and 4759 children, born within five years of the 2010 and 2015-16 Malawi Demographic and Health Surveys (MDHS) respectively, whose mothers had an HIV test result, were analysed. A best balancing method was chosen from a set of covariate balance methods namely, the 1:1 nearest neighbour (NN) matching, matching on the propensity score (PS) and inverse weighting on the PS. HIV and ART data were only available in the MDHS 2010, permitting an assessment of the moderating effect of ART on the association between maternal HIV infection and birth weight and perinatal mortality.

Results: In 2010, maternal HIV infection was negatively associated with birth weight (-25.3g, 95% CI:(-95.5, -7.4)) and in 2015-16 it was positively associated with birth weight (116.3g, 95 % CI:(27.8, 204.7)). Perinatal mortality was higher in infants of HIV-infected mothers compared to infants of HIV-uninfected mothers (OR = 1.5, 95% CI:(1.1 - 3.1)) in 2010, while there was no difference in the rate in 2015-16 (OR = 1.0, 95% CI:(0.4, 1.6)). ART was not associated with birth weight, however, it was associated with perinatal mortality (OR=3.9, 95% CI:(1.1, 14.8)).

Conclusion: The study has found that maternal HIV infection had an adverse effect on birth weight and perinatal mortality in 2010. Birth weight was not dependent on ART uptake but perinatal mortality was higher among infants of HIV-infected mothers who were not on ART. The higher birth weight among HIV-infected mothers and similarity in perinatal mortality with HIV-uninfected mothers in 2015-16 may be indicative of successes of interventions within the PMTCT program in Malawi.
