Gastroesophageal reflux disease (GERD) is a quite common disease caused by the reflux of gastric contents into the esophagus and manifested by heartburn and acid regurgitation. Apart from the esophageal manifestations, GERD is implicated in extraesophageal manifestations including pulmonary manifestations i.e. asthma, chronic cough, pneumonia, idiopathic pulmonary fibrosis, otolaryngological manifestations i.e. laryngitis, otitis, polyps, cancer of the larynx, chest pain [1,2]. The relationship between GERD and pulmonary manifestations is quite challenging and ongoing research efforts have focused on the elucidation of the pathogenesis of GERD induced asthma. 

Aim: To determine the correlation between mammographic features of breast cancer with molecular subtypes and to calculate the predictive value of these features. Materials and method: This is a retrospective study of breast cancer patients presenting between January 2017 and December 2021, who underwent mammography of the breast followed by true cut biopsy and immunohistochemical staining of the tissue sample. Breast carcinoma patients without preoperative mammograms, those unable to undergo histopathological and IHC examinations and h/o prior cancer treatment were excluded. On mammography, size, shape, margins, density, the presence or absence of suspicious calcifications and associated features were noted. Results: Irregular-shaped tumors with spiculated margins were likely to be luminal A/B subtypes of breast cancer. Tumors with a round or oval shape with circumscribed margins were highly suggestive of Triple negative breast cancer. Tumors with suspicious calcifications were likely to be HER2 enriched. Conclusion: Mammographic features such as irregular or round shape, circumscribed or noncircumscribed margins and suspicious calcifications are strongly correlated in predicting the molecular subtypes of breast cancer and thus may further expand the role of conventional breast imaging.

Background: Inflammation is associated with enhanced cardiovascular risk profile and increased cardiovascular mortality in end-stage kidney disease patients undergoing hemodialysis. Mechanisms of activated acute phase reaction in patients on chronic hemodialysis remain to be identified. As successful treatment of the inflammatory condition in these patients may improve long-term survival, we studied potential changes in different inflammatory biomarkers of cardiovascular risk in end-stage kidney disease patients after a mid-week hemodialysis session. Methods: Inflammatory biomarkers of cardiovascular risk (cystatin-C, homocysteine, C-reactive protein, procalcitonin, pentraxin-3, serum amyloid-A) and atherogenic plasma lipoproteins (Lipoprotein(a), cholesterol low and high density lipoproteins) were studied in 21 end-stage kidney disease patients previously and after a mid-week hemodialysis session. Results: We found a significant reduction in serum levels of low molecular weight molecules: cystatin-C (5.56 to 1.85 mg/L, 66.73%, p < 0.001), homocysteine (22.85 to 13.25 µmol/L, 42.01%, p < 0.001) and procalcitonin (0.788 to 0.457 ng/mL, 42.01%, p < 0.001). Large molecules as C-reactive protein (9.70 to 9.90 mg/L, 2.06%, p = 0.022) and pentraxin-3 (1.67 to 4.28 ng/mL, 156%, p < 0.001) increased, but serum amyloid-A decreased (15.90 to 12.70 mg/L, 20.13%, p < 0.05). There was no change in Lipoprotein (a) levels. Conclusion: Pentraxin-3 was a more specific inflammatory vascular marker than C-reactive protein, and the best inflammatory marker associated with hemodialysis. Homocysteine, procalcitonin and the other small proteins could be released and removed during hemodialysis session. Further studies are needed to understand the behavior and significance of these markers after successive hemodialysis.

Based on the differences between RNA and DNA, formulas for the natural frequency of torsional vibrations of single and double RNAs are obtained.It is shown that, despite the fact that millimeter waves are delayed by the skin of the human body, there are conditions under which they can freely penetrate through the human body.It is shown that centimeter waves, whose frequencies are multiples of the natural frequencies of torsional vibrations of the spirals of short DNA or RNA viruses, can cause subharmonic resonance in the spirals of RNA and DNA, which leads to the destruction of these molecules. Centimeter waves of non-thermal power flux density freely pass through the human body, which makes it possible to use them in vivo.A table has been compiled with the physical characteristics of DNA and RNA of the most dangerous viruses, indicating the frequencies of the external electromagnetic field that cause resonance in the DNA and RNA helices, which leads to the denaturation of molecules.In a series of experiments, it was shown that irradiation with microwaves with a resonant frequency of 180,402 GHz on samples with COVID-19 for 20 seconds. It has a disinfecting effect.

Aim and objectives: Endometrial Window of Implantation (WOI) is open in the midsecretory phase wherein the markers of invasion and cell adhesion are manifested .The primary objective was to find out the predictive value of Endometrial thickness and profile as a prognostic factors for embryo transfers during ART. Materials and Methods: Endometrial thickness assessment was performed with grey scale ultrasound on the day of transfer just before thawing the embryos in patients undergoing Frozen embryo transfer cycle after endometrial preparation. Results: The mean age and standard deviation of study population was is 33.26+5.95.Out of 69 patients there was clinical pregnancy in 33 patients , miscarriage in 10 patients and ongoing pregnacy in 23 patients. So the implantation rate was 47.83% (33/69), early miscarriage rate (pregnancy ending before 12 weeks) was 14.49%(10/69) and the ongoing pregnancy rate was 33.33% (23/69). Endometrial thickness < 6 mm had comparable implantation rates but low ongoing pregnancy rates. Conclusion: The ultrasound morphological and vascular grading of endometrial thickness and vascularity is useful to synchronise Day 5 embryo transfer and window and implantation thereby minimizing the loss of good embryos in nonreceptive endometrium.

Achieving this goal is impossible without changes in teaching methodology, teaching technologies and teacher’s work.The article is an overview and focuses on the following issues. In the information society, the era of biocomputers and quantum computers is coming, which will use not only artificial intelligence, but also artificial consciousness for simulation. Artificial awareness builds the foundations for the development of robots that will be widely used in various fields of industry and science. - Artificial awareness combined with artificial intelligence can be an innovative method in education and communication; - Quantum computers and biocomputers will find wide application in human education and social life;

Case report: This case report aimed to evaluate temporomandibular joint activity in a patient with the temporomandibular disorder before and after disclusion time reduction (DTR) therapy.Results: Positive changes in joint health were observed in the patient after the DTR treatment. Conclusion: The joint vibration analysis objectively showed significant results with the disclusion-time reduction therapy. The measured parameters were closer to the reference values. Thus, DTR is an effective method to treat TMJ disorders, based on Piper’s classification.

Peripartum cardiomyopathy is one of the curable cardiomyopathy. It’s a severe and frequent disease arising among women of childbearing age. Its evolution in the long-term among some patients leads to chronic heart failure. Our study aims to determine from a prospective cohort, the factors associated with the non-recovery of myocardial function upon 12 months of diagnosis. Sociodemographic, clinical and echocardiographic data were collected at the time of diagnosis and then in months 3, 6 and 12. The outcome was the non-recovery of myocardial function at one year, defined by a left ventricular ejection fraction (LVEF) below 50%. 60 patients were analyzed after 12 months of follow-up. Mortality was about 13.3% and recovery rate of myocardial function reached 42.3%. After logistic regression, delay diagnosis and observance were the factors related to non- recovery of myocardial function.

Caregivers of Children Living with HIV/AIDS experience severe burdens in Africa amidst unmet needs while seeking care from hospitals. This study aimed to explore the diagnosis history, health-seeking behaviour, and care provided by hospitals and whether the services meet caregivers’ expectations. We used a qualitative approach and conducted individual in-depth interviews among purposively sampled caregivers of children living with HIV/AIDS from three hospitals. We achieved data sufficiency after interviewing nine participants. Audio-recorded interviews were transcribed verbatim and thematically analyzed manually through Collaizi’s steps. Four themes developed including; history of pregnancy and poor HIV testing, effective care for caregivers and CLWH, attitude of healthcare providers, and unmet expectations of care. Healthcare providers showed positive attitudes towards caregivers and provided services (counselling, dispensing Anti-retrovirals, health monitoring, and coordination of clinical care). Expectations bordered on financial support (for food, education, health care), and treatment for opportunistic infections. Findings indicate gaps in HIV voluntary testing for pregnant women, enrollment in Prevention of Mother to Child Transmission (PMTCT), and unmet needs. It is imperative to improve coverage of testing for pregnant women and efforts made to meet their needs. Financial support, provision of food security, and assistance for caregivers are essential for care.

Background: The clinical manifestations of Corona Virus Disease of 2019 (COVID-19) varied from patient to patient with evidence of multi-organ involvement. Many patients continue to have a wide range of symptoms for variable periods of time. The long-term effects of COVID-19 infection (post-COVID-19 illness or syndrome) are not yet been fully explored.This study aims to highlight the clinical manifestations of the acute COVID-19 infection and the longer-term manifestations of the disease among the attendants to a private GP clinic in the Urban Amman Area, Jordan.Methods: A clinical case-series study was conducted on a sample of 300 COVID-19-positive cases among patients attending my private GP clinic in the Urban Amman Area, Jordan. We used the structured questionnaire based mainly on World Health Organization (WHO) Case Report Form (CRF) verified tool for post-COVID-19. All patients with COVID-19 were included in the study. Data collection was conducted through phone calls and analyzed using the Statistical Package for Social Sciences (SPSS) software. Results: The incidence of COVID-19 among patients attending the clinic during the period of this study was 25%. Females were 135 (45%) of the study population and males were 165 (55%). The mean (SD) of age was 34.2 (5.0) years. Most of the infected staff (90%) were symptomatic and developed acute COVID-19 symptoms. Fever, Cough, Fatigue, joint pain and loss of smell and taste were the most common symptoms. 72% of the study population had fully recovered from the infection, while 28% of them continued to suffer from many long symptoms. Fatigue (28%), shortness of breath on activity (18%), Social withdrawal (18%), anxiety (17%), forgetfulness (16%), trouble concentrating (15) and depressed mood (14%) were the most frequently reported long symptoms.Conclusion: The prevalence of Post COVID-19 illness was 28% with a high public health burden calling for the public health system to address the medical and psychological needs of affected persons. Mental health and psychosocial support are recommended elements for the management of patients.
