Hypertension.
The morphological changes in myocardial tissue in spontaneously hypertensive rat (SHR) occurring after administration of propylthiouracil (PTU) were assessed in the project. PTU at a concentration of 0.1% was given to the animals with drinking water for 47 days. After the end of the experiment, the morphological parameters of cardiomyocytes, the density of cardiomyocytes and fibroblasts in the myocardium, and the average area of the lumen of veins were examined. The progressive development of dystrophic processes in the myocardium was established against the background of PTU intake, which was characterized by a decrease in the cardiomyocyte density and an increase in the volume of connective tissue, venous congestion, and expansion of the lumen of veins.

COVID-19.
Coronavirus disease-2019 (COVID-19) is an infectious disease that has spread worldwide and led to ongoing global concern. The pandemic prompted researchers to examine the impact of COVID-19 on human organs. The heart is one such organ. This study investigates the possible prediction of heart condition using some biochemical markers of particularly critically ill patients referred to an intensive care unit (ICU). Results of various serum biomarkers of patients infected with COVID-19 receiving treatment in the ICU, Asir Central Hospital, Asir Region, Saudi Arabia, were extracted and compared with healthy individuals using the Mann–Whitney U test. The study showed a distinguished increase in total Serum creatine phosphokinase-Total (CPK-Total), Serum creatine phosphokinase-MP (CPK-MP) levels among COVID-19/ICU patients. But, this increase was not statistically significant. Besides, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase levels revealed a statistically significant increase in the infected group compared with controls. Examination of electrolytes showed a reduction in calcium median value in COVID-19/ICU patients. Data revealed a possible influence of COVID-19 on the heart. Herein, we observe significant parameters that may reflect cardiovascular injury elicited by the virus. These biomarkers possibly used to monitor the severity of disease on the cardiovascular system.

COVID-19.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a pandemic infection that emerged in December 2019 leading to an outbreak worldwide. We aimed to investigate the hematological parameters and coagulation profiles specifically for the referral of coronavirus disease 2019 (COVID-19) patients to intensive care unit (ICU) due to the severity of illness to determine a pathognomonic association of infection severity and the hematological markers. The pathognomonic markers could assist physicians in better management of the infection to reduce mortality and morbidity. Thirty patients infected with COVID-19 who were receiving treatment during November and October 2020, in the ICU at Asir Central Hospital, Asir Region, Saudi Arabia, were recruited. The age of patients ranged between 30 and 90 years old. COVID-19 patients in the ICU displayed a statistical reduction in red blood cells (RBCs), hemoglobin (HBG), and hematocrit (HCT). Leukocytosis, neutrophilia, thrombocytopenia, and lymphocytopenia were significant in ICU COVID-19 patients. Hematological parameters and coagulation profiles may be used as signs to predict the severity of the coronavirus infection. COVID-19 cases in the ICU showed a dramatic change in hematological parameters and coagulation profiles, indicating that the virus may interfere with hemoglobin, platelet, and immune cell functions through either inhibition or stimulation, leading to severe complications.

Orthopaedics.
Management of infected gap non-unions of long bones has always been a challenging undertaking. Issues like compromised vascularity of bone, poor soft tissue envelop, persistent infection along with bone gap makes treatment complex. Staged treatment with fibular graft is a promising method for bridging the gap in bone defects created by debridement and sequestrectomy. Therefore, the objective of our study was to evaluate the outcome of non-vascularized fibular strut grafting in the management of infected gap non-union of long bones in paediatric patients. The prospective study included patients ≤ 14 years, with an infected gap non-union of long bones due to haematogenous osteomyelitis. Non-unions due to trauma, tumour, or other causes were excluded. Pre-operative evaluation of the patient included age, sex, anatomic site, and size of the bone gap. Staged treatment protocol for adequate healing of the infection as well as non-union was undertaken. The primary outcome measure was bone healing which was defined as complete fracture union with fibular graft incorporation and hypertrophy. Secondary outcome measures were mal-union, delayed union, peri-implant fracture, and re-activation of infection. Nine patients underwent staged treatment for infected gap non-unions with a mean age of 5.78 years. The average size of the bone gap was 5.83 cm. The average time between stage I and II surgeries was 3.56 months. The mean follow-up was 32 months. The most common bone involved was the femur (n = 6). Successful eradication of infection and consequent healing of non-union occurred in 7 (77.8%) patients. Non-union was seen in two (22.2%) patients. Stable fixation of graft with plate resulted in better outcome. Average time of radiological union was 6.5 months (range 5 - 9 months). Hypertrophy of fibula was evident radiologically at one-year follow-up in all of the patients, except two with graft failure. Delayed union and reactivation of infection were seen in one patient each. Limb-length discrepancy (mean = 5.5 cm) was seen in all patients with lower-limb involvement. Regrowth of the fibula was seen in all patients, and no patient developed common peroneal palsy. The use of non-vascularized fibular graft as a staged procedure for the treatment of infected gap non-union in children is a promising technique, which brings forth predictable and reproducible outcomes in all hands without the need for any microsurgical expertise. In addition, it has a minimal complication rate. Finally, the role of stable fixation in graft incorporation warrants further study.

Urethral Stricture.
Urethral calculi are uncommon diagnoses. Large urethral stones with peculiar shapes have been reported. Management of such large stones depends upon size, shape, position, and associated abnormality of the urethra. We present a case of dumbbell-shaped large calculus secondary to bulbar urethral stricture. The patient was managed with Suprapubic cystotomy, antibiotics. Retrograde-urethrogram and micturating cystourethrogram showed bulbar urethral stricture. Trans vesical removal of stone was attempted; however lower part of the calculus was impacted. Perineal retrieval of the calculus was done, followed by stage 1 urethroplasty with perineal urethrostomy. After three months, stage 2 urethroplasty was done.

Overseas Medical Treatment.
More and more Sri Lankans reach for overseas medical treatment with the raising standards of living in the country. However, it is largely an unexplored area. Economic burden of overseas medical treatment is largely an out-of-the-pocket expenditure. Considering the economic burden and low health insurance penetration among Sri Lankans, healthcare decision-makers should explore the clinical dynamics of this subset of patients to improve the services within the country. The study aimed to describe the clinical characteristics and cost of medical treatment by medical travellers for treatment overseas. A descriptive study was carried out by a team of experts analyzing the data of estimated overseas medical expenditure recorded at the President Fund, a body established to assist Sri Lankans who need financial assistance for the said purpose. The team studied the deidentified databases for 2018 and 2019. Of the 60 patients studied, liver transplant, treatment for scoliosis, and bone marrow transplant topped the list by the number of cases and the estimated cost for the procedure overseas. Advance cancer treatment, cardiac surgery, and brain and spinal cord surgery also contributed significantly to the burden. Highest estimated unit cost per procedure has been recorded by the liver and bone marrow transplant surgeries. In conclusion, the healthcare decision-makers should liaise with relevant professional bodies to establish liver and bone marrow transplant services, advance brain and spinal cord surgery including treatment of scoliosis, and advance cancer treatment and cardiac surgeries. Considering the lack of data sources on the economic burden of overseas medical treatment, authorities should act promptly to capture nationwide details of this important group of patients.

COVID-19
COVID-19 is an infectious disease that rapidly developed into a pandemic status. This deemed a need for new strategies to carry out routine health care activities. The recent practices and adaptations of the system as a response to the pandemic status were called a new normal situation. The aim of the study was to describe principles for adaptation to a new normal context for health care settings in COVID-19 pandemic. This narrative review of literature was conducted based on policy documents, guidelines, and public notices issued by the government and other key policymakers from the United Kingdom, Australia, Singapore, and Canada between June 15, 2020, and July 15, 2020, available on their government websites. The study revealed several principles, namely, enhanced surveillance, phasedown strategy for restoring routine services, vulnerability, dynamics of the service demand, new principles in human resource management, infection control measures, supply and usage of personal protective equipment, demand for intensive-care unit bed capacity, coordination and collaboration internally and externally, promotion and utility of remote care, ensuring equity, pre-hospital communication and assessment before reaching service facility, enhancing clinician participation in local-level decision-making, and risk assessments within all levels of service facility. The results of this study exposed new principles that facilitated managerial decision-making to the adaptation of new strategies. This new normal context created many challenges for resource management, which needed to consider dynamics of demand of services, prevention of spreading infections, and readiness for surge of cases while safeguarding quality and safety.

Alternative Rice Establishment Method.
Water and labor for agriculture are becoming increasingly scarce resources in many rice production areas. The share of water in agriculture is declining because of its increased demand in other non-agriculture sectors. Groundwater is being depleted at an alarming rate, especially in South Asia and the same is the case in India mainly because of its heavy use for rice production. Similarly, labor availability for agriculture is declining because of increased demand in non-agriculture sectors associated with rapid economic growth in many Asian countries. These factors provide incentives for farmers to shift to direct seeding, which requires less water and labor. Direct seeded rice production system gives a similar result with respect to growth and yield as found in transplanted puddled rice. However, due to the lower cost of cultivation B:C ratio is higher in direct seeded rice as compared to transplanted rice.
