The pandemic of COVID-19 has adversely affected the world in many aspects. The health and economic sectors suffer most of the repercussions of this disease. The search for a cure for this rapidly spreading virus which is causing massive life losses worldwide requires clear understanding of the immunopathogenesis of this virus so as to develop pinpointed targeted therapies rather than relying mainly on supportive care measures and drug repurposing to fight this life-threatening virus infection. Neutrophils, neutrophil extracellular traps (NETs), and NETosis are not well studied not only in COVID-19, but also in coroviruses in general. The review will shed lights on the functions of neutrophils, NETs, and NETosis in various infectious complications as well as in sepsis and acute lung conditions in an attempt to understand their actual roles and in order to help in designing targeted therapies in the near future.

Context: Shoulder pain is one of the most frequent reported complaints in intensive competitive swimming. The so-called ‘swimmers’ shoulder’ has been widely explored and has been reported sometimes without specific reference to contributing mechanisms or structures. Somatic dysfunction is defined as an impaired or altered function of related components of the somatic system and may appear in the early stage of pain feeling. Aim: To evaluate somatic dysfunctions in a group of young competitive swimmers with and without shoulder pain and its relationship with the shoulder’s mobility along with the efficacy of an osteopathic manipulative treatment (OMT) on shoulder’s mobility, pain, and comfort of swimming. Material and method: 20 competitive swimmers (14.6 ± 1.3 ys; 11.6 ± 2.4 hs.wk-1) were divided into two groups, with and without shoulder pain (SPG/CG). Before and after light touch/OMT, and 1 week later, somatic dysfunctions, shoulder’s range of mobility, pain, and swimming comfort were assessed by 2 independent osteopaths. Results: Somatic dysfunctions were observed in both groups without significant differences in the number or localization and were independent of severity of pain. In the SPG, pain decreased significantly after OMT (6.1 ± 1.9 vs. 3.9 ± 1.8; p = 0.001) and remained stable 1-week later (P = NS). Shoulder’s mobility was lower on the aching shoulder in the “shoulder pain” group when compared to the control group on flexion and abduction tests but not on extension or adduction tests. Following OMT, only abduction improved when compared to light touch. Comfort in swimming was reported as “better” in both OMT/light touch groups. Conclusion: There is no difference between light touch and OMT as both decreased pain and increased comfort in swimming but abduction range of motion only improved in the OMT group.

The incidence of heart failure with preserved ejection fraction (HFpEF) continues to rise, and obesity continues to be a predominant comorbid condition affecting patients with HFpEF. Recent research sheds light on the important pathophysiologic role that obesity plays in the development of HFpEF, with many areas of opportunity existing for future developments in understanding the etiology and management of the disease. Crucial in these pathophysiologic developments are studies that clearly characterize the obesity phenotype in HFpEF and compare it to presentations of HFpEF in patients without obesity. This paper reviews the existing literature on the obesity phenotype within HFpEF and discusses some of the prevailing ideas behind the pathophysiologic interplay between the conditions, as well as the existing treatments demonstrating improved outcomes in HFpEF.

Trichomonas vaginalis could be seen in Pap smears where it is reported, but because main concerned is placed on malignant cells in Pap smears, not much effort is done to search for this parasite in smears. In this study, 100 cervical and vaginal specimens were examined microscopically by the conventional Papanicolaou method and liquid base cytology (LBC) for the presence of Trichomonas vaginalis (T.vaginalis). 16% were infected with T.vaginalis while 10% of diagnosis based on both perinuclear halo and T. vaginalis presence although the association between perinuclear halo and T, vaginalis is statistically insignificant it is recommended to increase the number of the cases to prove or disprove the association

Diabetes mellitus increases the possibility of different cancers. Scientists have substantiated the link of diabetes with increased prevalence, augmented progression and improved cancer aggression. Research has strengthened link of diabetes with the colorectal cancer risk among various cancers. Diagnosis and treatment have made some progress in recent years, but Colorectal is major issue for the health of people even today. In order to reduce cancer mortality, there is importance of prophylaxis, evaluation and proper treatment. Factors distressing cancer prognosis is required by policy-making system for beneficial approaches of cancer patients and improvement of disease. Eventually diabetes- specific strategies for different cancers are explored.

Coronary artery aneurysm is commonly defined as a localized dilatation exceeding the diameter of adjacent normal coronary segments by 50% [1]. Coronary artery aneurysms may be fusiform, involving the full circumference of the coronary artery, or saccular, involving only a portion of the circumference [2]. Causes of coronary artery aneurysms include atherosclerosis (accounting for 50% of cases), Kawasaki disease, polyarteritis nodosa, infection, trauma, coronary dissection, percutaneous coronary angioplasty, and congenital malformations [3]. The abnormal blood flow within the coronary artery aneurysm may lead to thrombus formation, embolization, rupture, myocardial ischemia or myocardial infarction [4]. Here we present a case of a giant fusiform coronary artery aneurysm who passed away due to coronary rupture after acute myocardial infarction.

An enquiry into the lack of attention awarded to serotonin antagonism in the treatment of arterial thrombosis revealed that the mode of action of serotonin and its platelet receptor antagonists was an action upon thrombus growth, and not, as with other anti-platelet drugs upon the initiation of thrombosis. This lack of effect could explain why this approach has been considered not to be effective. However under conditions of arterial stenosis in which there is platelet activation by increased shear stress, and during the growth phase of arterial thrombi, serotonin 5HT2A antagonism has been demonstrated to have great potentcy in dispersing thrombotic obstruction to blood flow. This mode of action, the lack of participation of serotonin in haemostasis, and the absence of serotonin in wounds accounts for the proven lack of effect of effect of pure specific 5HT2A antagonists (i.e., not those with other actions) on operative bleeding and skin bleeding times. This lack of effect on haemostasis solves the dosing problem encountered with other anti-thrombotic drugs, with which drug concentration cannot be controlled with single fixed doses, leading to the association between increased anti-thrombotic efficacy and increased bleeding complications. Thus 5HT2A antagonism appears to be the preferred approach, from the point of view of safety and lack of bleeding risk; this consideration applies particularly to thrombosis therapy in the context of traumatic accidents, surgical operations and invasive procedures such as angioplasty.

Woven coronary artery (WCA) is an extremely rare and still not a clearly defined coronary anomaly. It is characterized by the division of epicardial coronary artery into thin channels which then reanastomose with the distal part of the abnormal coronary artery [1]. Since the angiographic imaging of WCA looks like an intracoronary thrombus and dissection; the differential diagnosis between atherothrombotic coronary arteries with recanalization of organized thrombi in coronary arteries and WCA may be very difficult for invasive cardiologists, especially in patients with single or two coronary artery involvements [2].

Functional appliances used in correction of class II malocclusions are shown to modify the neuromuscular environment of dentition & associated bones. There are many studies related to the skeletal, dental and neuromuscular changes which are evaluated cephalometrically, clinically as well as with the recent diagnostic aids like MRI. The aim of this short communication was to highlight and discuss the different aspects of condylar modifications and its role in its growth. The Twin Block has higher effectiveness & comfort as compared to other removable functional appliances [1.2]. The action of Twin Block & Bionator is for 24 hours so effects are more with these appliances. Over the years, several theories have emerged attempting to shed light on condylar growth. One of the earliest theories, the genetic theory, suggests the condyle is under strong genetic control like an epiphysis that causes the entire mandible to grow downward and forward. Although this may be related more to development of the prenatal than postnatal condyle, the theory does indirectly question the effectiveness of orthopedic appliances in condylar growth as proposed by Brodie [3,4]. Several long-term investigations actually showed clinically insignificant condylar growth modification after continuous mandibular advancement with a reasonable retention period in human beings although the initial treatment results appeared encouraging. This leads to the conclusion that the general growth of the condyle appears relatively unalterable in long-term studies. A second hypothesis based on the earliest available acute and blind EMG monitoring technique, suggests that hyperactivity of the lateral pterygoid muscles (LPM) promotes condylar growth. Rees reported that other muscles and tendons, including those of the deep masseter and temporalis, also attach to the articular disk region. Attachments of the LPM to the condylar head or articular disk may be expected to cause condylar growth, but anatomic research has not found evidence that significant attachments actually exist [5,6]. The LPM tendon is observed attaching, however, to the anterior border of the fibrous capsule that in turn attaches to the fibrocartilage of the condylar head and neck anteriorly. At the same time, it is doubtful that initial hyperactivity could occur where the LPM muscle has been shortened by continuous mandibular displacement therapy. By using LPM myectomy in rats, which may have disrupted condylar blood supply, Whetten and Johnston found little evidence that LPM traction had any pronounced effect on condylar growth. More recently, permanently implanted longitudinal muscle monitoring techniques have found that the condylar growth is actually related to decrease postural and functional LPM activity. This notion was also supported in human studies by Auf der Maur, Pancherz and Anehus- Pancherz, and Ingervall and Bitsanis that reported decreased muscle activity. The LPM hyperactivity theory brought forward by Charlier et al. Petrovic, and later espoused by McNamara however, was important in prompting further investigations in muscle-bone interactions [7,8]. A third hypothesis, the functional matrix theory, postulates the principal control of bone growth is not the bone itself, but rather the growth of soft tissues directly associated with it. Although this was supported in part by investigations testing the different growth and developmental responses between the condyle and epiphysis, there has been no explanation as to exactly how condylar growth would be stimulated. Thus, this theory’s validity has been questioned. One of the reasons was that there was little explanation of the specific mechanism by which the condyle was stimulated to grow. Endow and Hans presented an excellent overall perspective suggesting that mandibular growth is a composite of regional forces and functional agents of growth control that interact in response to specific extra-condylar activating signals [9,10].

This article shows the driving factors of rural women's participation in the TWITEZIMBERE and REKATUJANE rice cooperatives in the GIHANGA commune. These factors are related to the preservation of traditional culture in Burundi in general and in rural areas in particular, where women are in the majority. To achieve this, the research methodology used is both qualitative (individual interviews and documentary research) and quantitative (questionnaire administered to respondents). The results of this research show that traditional culture has forced rural women to stay at home to care for children and perform various household chores. This situation of isolation leads to a lack of information about the benefits of rice-growing cooperatives and the value they can bring to their members. It is also observed that rural women lack the will to adopt the new rice farming practices in Cooperatives. This situation of lack of will to adopt new behavior has hindered the massive participation of rural women in rice cooperatives. Finally, the article emphasizes that the illiteracy of these rural women and the lack of external technical and financial support are considered other important factors that constituted the barriers to their massive participation in rice cooperatives. To deal with this series of problems, the researcher has discovered strategies that can encourage rural women to participate massively in rice cooperatives, in particular, to become members of rice cooperatives that help their members to make them known and receive external technical and financial support, for example, incentives from the government. For this, the Government must therefore help them by providing multifaceted support including local and foreign technical and financial partners. Similarly, cooperative leaders might seek out various donors for their agricultural cooperative associations.
