A total of 5,134 strains of Xanthomonas campestris pv. vesicatoria obtained from diseased pepper and tomato fruits at 22 diverse locations on the East Caribbean islands of Antigua, St. Christopher, St. Lucia, and Grenada were assessed for pathogenicity, taxonomic group phenotypes, and sensitivity to copper, zinc, and streptomycin. Altogether, 15 known races, namely T1, T2, P0T1, P0T2, P1T1, P1T2, P2T1, P2T2, P3T1, P3T2, P4T2, P5T2, P5T3, P6T2, and P6T3, were detected. Races T1, P0T1, P0T2, P1T2, P2T1, and P3T1 were common to all islands except St. Lucia. St. Lucia had races P2T2, P3T2, P4T2, and P6T2 in common with Grenada and two races each from among the four pathotypes in common with Antigua and St. Lucia. Races T1, P1T2, P3T1, and P3T2 were the most abundant strains of the bacterium in Antigua, whereas the two latter pathotypes, as well as races P0T1 and P2T1, were among the most prevalent strains in St. Christopher. In contrast, races P6T2 and P5T2 predominated in St. Lucia, and P6T2, P1T2, and P3T2 were the abundant pathotypes in Grenada. Generally, the largest bacterial spot fruit lesions were associated with the predominant races on each island, and the smallest lesions were generally linked to races capable of overcoming gene Bs2. Only these latter races were similar to group B strains of X. campestris pv. vesicatoria with respect to the presence of β-protein in their cellular protein profiles, ability to hydrolyze starch, and inability to oxidize cis-aconitate. Other race types tested resembled group A strains of the bacterium in their ability to utilize cis-aconitate, inability to hydrolyze starch and pectate, and the presence of the α-protein in profiles of cellular proteins. Copper-resistant strains of X. campestris pv. vesi-catoria constitute 8.7 to 10.6% of the pathogen collections from Antigua and St. Christopher and 44.4 and 66.7% of pathotypes from St. Lucia and Grenada, respectively. Almost all strains were sensitive to zinc. Streptomycin resistance was observed among 62% of the strains in St. Christopher and Grenada and 62.8 to 83.6% of those in Antigua and St. Lucia.

A series of 40 patients with TIA (25 males and 15 females) was thoroughly investigated by means of angiography and computerized tomography, and divided into a group (A) of 15 “sine materia”, and a group (B) of 25 with direct or indirect evidence of vascular occlusive or stenotic changes. Blood viscosity at 230 sec-1 37° was cp 4.2 ± 0.3 in the controls, cp 4.7 ± 0.7 in all patients (p < 0.05) cp 4.98 ± 0.7 in all male patients (p < 0.01 versus male controls), and cp 4.75 ± 0.8 in group B (p < 0.02). Haematocrit and Fibrinogen were also significantly increased in all male patients and in group B. Circulating platelet aggregates (CPA) were increased in 40% of the patients. Almost all patients with elevated CPA were males, with a slight prevalence in group B. Changes in blood viscosity parameters and in platelet aggregation in TIA patients were therefore related both to evidence of vascular lesions, and to sex, since they were found to prevail in male patients of both groups.

Abstract Forty-two nonhypertensive patients with a proven subarachnoid hemorrhage but normal cerebral panangiography were investigated. The follow-up period was 1 to 5 years, with a mean of 39.1 months. Treatment consisted of 2 weeks of bedrest and sedation, followed by progressive mobilization on the 3rd week. Thirteen patients (Group A) were treated with tranexamic acid, whereas 29 patients (Group B) received no antifibrinolytic therapy. Five patients of Group A died of ischemia caused by cerebral vasospasm. No patient of Group B died, and there was no early rebleeding in either group. Therefore, antifibrinolytic therapy is not indicated in these patients. Only 1 of 42 patients (2.4%) experienced late rebleeding, and he again had normal cerebral panangiography. Reangiography several weeks or months after the first hemorrhage seems not to be indicated. The overall prognosis of the surviving patients was good; almost all were able to return to their previous occupations within 6 months after the hemorrhage.

Objectives: External root resorption is the complication of intra-coronal bleaching done with 30% H2O2alone or mixed with sodium perborate but not with sodium perborate mixed with water. The study was done to comparatively evaluate the H2O2 leakage from three H2O2 liberating bleaching agents. Study design:Fifty one single rooted human teeth were used. After root canal therapy gutta percha was removed below cemento-enamel junction. Three bleaching agents: sodium perborate mixed with water , sodium perborate mixed with 30% H2O2 and 30% H2O2 alone were used. Teeth without defect , with cervical root defect and with mid root defect constituted group A, group B and group C. According to various bleaching agents groups were subdivided into subgroup 1, 2 and 3. H2O2 leakage was measured with the help of spectrophotometer. Results: Almost all teeth showed H2O2 leakage. It was maximum in B1 followed by C1, B2,A1, A2, C2, B3, A3 and C3. Conclusion: Sodium perborate mixed with water was found to be the best bleaching agent.

Objective of this research was to determine the slaughter properties and carcass composition of carcass sides derived from young cattle of Domestic Spotted breed, of pre-slaughter weights of 500 (group A) and 600 kg (group B). Heavier cattle had higher share of kidney fat in carcass, whereas the share of offals showed no significant differences. Statistically significant difference was registered only in share of toungue (P<0.05), that was higher in cattle of group A. Share of extra/premium (tenderloin), I category (round) and II category (loin, back, shoulder) showed no significant differences between groups of cattle. Statistically significant difference (P<0.05) was established in the share of III category carcass parts. Share of forearm and chest was significantly higher in lighter cattle (3.55% and 7.95%) compared to heavier animals (2.89% and 6.33%), whereas the share of subshoulder was considerably lower in group A (6.89%) compared to cattle of group B (9.73%). Data obtained by dissection of main carcass side parts differed significantly in regard to the share of muscle tissue in round and belly, that was significantly higher in cattle of group A (P<0.05). Share of fat tissue (subcutaneous and intermuscular) was higher in cattle of group B in almost all carcass side parts, however, statistically significant difference between groups was determined only in round, back, neck and subshoulder. Also, share of bones in chest differed statistically significantly (P<0.05) and it was higher in group A (20.09%) compared to cattle of group B (15.52%).

The disease caused by coronavirus SARS-CoV-2 (COVID-19) can affect almost all organs of the human body, including kidneys. We conducted a one-center study to comprehensively analyze the effects of kidney involvement on the course and outcomes in patients hospitalized with COVID-19, depending on the estimated glomerular filtration rate (eGFR) at admission. Out of the 1958 patients, 1342 (68.54%) had eGFR ≥ 60 mL/min/1.73 m2 (group A) and 616 (31.46%) had eGFR < 60 mL/min/1.73 m2 (group B). Group B was additionally divided into subgroups B1, B2, and B3 based on eGFR. We found that mortality rates during hospitalization, as well as after 90 and 180 days, were much higher in group B than group A. The highest mortality was observed in the B2 subgroup with eGFR of 15–29. The mortality of B patients was associated with comorbidities, respiratory dysfunction, immunological impairment, and more frequent development of AKI. AKI had a negative impact on patients’ survival, regardless of the initial renal function. At discharge, 7.4% of patients had serum creatinine levels 30% higher, or more, as compared to admission. The disease course and outcomes in COVID-19 patients are associated with baseline eGFR; however, AKI during hospitalization is a more significant predictor of poor prognosis regardless of the initial renal function.

Abstract Background COVID-19 has become a new infectious disease in the global pandemic, most of which are non-severe patients. It is particularly important to understand the dynamic changes of the whole disease course of non-severe patients from the onset to the follow-up after discharge.Methods On February 1, 2020, 18 cases of non-severe COVID-19 appeared in a hospital in Beijing. We recorded the clinical information and viral dynamics of these patients from the onset of the disease to one month after discharge.Results Eighteen patients (median age 43) were included, including 14 females. Fever (11/18) and cough (8/18) are the most common symptoms. According to the degree of lung inflammation, 18 patients were divided into two groups (group A imaging score ≤ 10; group B imaging score > 10). The duration of SARS-CoV-2 positive in group A was significantly longer than that in group B (the median was 30 and 13, respectively, P = 0.0025). One month after discharge, almost all patients were followed up for IgM antibody disappearance and IgG antibody production.Conclusion In non-severe COVID-19 patients, the positive duration of the SARS-CoV-2 in patients with mild lung injury was longer than that in patients with severe lung injury. The possible mechanism is that the virus-mediated immune system is not fully activated in mild damaged patients.

ABSTRACTDuring the novel coronavirus pandemic, also known as SARS-CoV-2 or COVID-19 pandemic, frontline healthcare professionals suffered psychological as well as pathological trauma due to the lack of preparation to cope with this unforeseen situation. The protocols to prevent the spread of this disease proved to be less effective than anticipated. In these circumstances, improvement of the existing triage system was felt and an AUDIO-VISUAL TRIAGE (AVT) system was introduced to enhance confidence as well as increase the safety of frontline healthcare professionals. The current analysis was performed from March 21, 2020, to April 28, 2020, until the completion of sixty response forms, at Bahria Town International Hospital, Lahore. Thirty participants (Group A) deployed on visual triage and other thirty (Group B) on AVT for screening suspected cases of COVID-19 infection. Anxiety levels were measured by using the GAD-7 scoring system and the participants of both groups were periodically tested for COVID-19 infection by PCR. Independent t-test was used to evaluate the significance of different variables at a confidence level of 95%. The result of the current study revealed the effectiveness of AVT for the screening of COVID-19 patients. There was a statistically significant increase in anxiety levels and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection rate in group A as compared to group B. Almost all participants in group A wanted to shift their place of work or ready to quit the job if they were forced to perform their duties at the same visual triage. AVT system for COVID-19 screening found to be more safe and less stressful than visual triage. It is not only a simple and effective way to prevent the spread of diseases but also boosted the confidence of frontline healthcare professionals to fight against coronavirus spread.

Background: Down Syndrome (DS) is the most common chromosomal abnormality with an incidence of 1:700 live births. Alzheimer’s disease (AD) affects almost all of these individuals from the age of 30, whose susceptibility is on the rise with increasing life expectancy. However, interventions can limit or improve cognitive decline. Objectives: To compare early interventions in the prevention of AD in patients with DS. Methods: Randomized Controlled Trial published in English, in the last 5 years, in humans, at PUBMED. Were included studies involving participants over 18 years old, diagnosed with DS and those with unclear interventions were excluded. Six articles were found and after applying the criteria, two studies were part of this review. The PRISMA scale was used. Results: Ptomey et al. (2018) intervened with online exercise, selecting 27 participants divided into two groups: A) one session/week; B) two sessions/ week. After 12 weeks it was observed that group B showed improvement in learning compared to group A. Sano et al. (2016) performed an intervention with Vitamin E (VE) for three years in 337 individuals, segregated in: A) 1,000 IU, orally, twice/day; B) placebo. There was no significant difference in the progression of cognitive, functional, behavioral and clinical deterioration between the groups. Conclusions: The practice of physical exercise proved to be promising in the prevention of AD, however the use of VE did not show significant results. Further studies on the subject are needed.

Objectives: 1. To find out the affect of surface wetting of existing surgical gownfabric before and after laundering (among three groups of hospitals). 2. To compare the resultsof surface wetting of existing surgical gowns among three groups of hospitals. Study Design:The study has Experimental design. Period: March, 2017- June, 2017. Setting: This fabricwas collected from different govt. and private hospitals under study. Materials and Methods:The surgical gown fabric was used as sample for experiments. All the experimental work wasdone at PCSIR Labs. Lahore. Result and Conclusion: According to the above graph figure 04the resistance of fabric to surface wetting (spray test) was absolutely same in Group B and C.However, in Group A, the values were slightly greater than other two groups from new gown to10th laundering intervals and became null in further laundering, similar to group A and B. Theresistance to surface wetting nullified in almost all groups after 5th laundry and no statisticaldifference was observed in resistance of fabric in all groups i.e. (p-value=0.423). These gownsdid not match any international standard or parameter either. After repeated launderings mostof the gowns were torn and became discolored. Among three groups under study group Ashowed highest ratings in ISO-Spray test where as for weft yarns group c failed the test.

Background: Diabetes is a most prevalent chronic disease and has reached to alarming stage in almost all developed and developing countries. Worldwide approximately four hundred millions of people are living with diabetes and it is a leading cause of death. Aims and objectives is to study effectiveness of addition of drug Teneligliptin to Metformin, Glimepiride, Pioglitazone combination in type II Diabetic patients.Methods: This was a cross sectional study carried out in the department of Medicine of a tertiary health care centre during the one year period i.e. January 2017 to January 2018 in the type II diabetic patients. Out of all type II diabetic patients 40 patients who were on the treatment for hypoglycemia with drugs Metformin, Glimepiride, Pioglitazone were selected out of these randomly 20 patients were continued on the previous treatment (Group B) and remaining 20 were given additional drug Teneligliptin (Group A). The statistical analysis was done by unpaired t-test and chi-square test analyzed by SPSS 19 version of software.Results: In this study Authors have seen that the average age in both the groups was comparable i.e. 36.78±6.74 and 38.92±5.87 (p>0.05, t=1.24, df=38), the sex ration was also similar in both the group (p>0.43, χ2=0.43, df=1) and the HbA1C was comparable at 1st Wk. 10±4.56 - 9.87±3.42 (p>0.05, t=1.023, df=38) and 4th Wk. 8±5.23 - 9.67±4.52 (p>0.05, t=1.0804, df=38) but significantly differed at 8th Wk. 7.12±2.34 - 9.92±3.56 (p<0.01, t=3.82, df=38), 12th Wk. 5.98±1.98 - 9.24±2.79 (p<0.001, t=4.26, df=38) respectively in Group A and B.Conclusions: It can be concluded from this study that the addition of Teneligliptin significantly reduced the HbA1c level at the end of 4th wk. and hence superior to conventional Metformin, Glimepiride, Pioglitazone only combination treatment.
