Abstract
AIM To assess the impact of untreated dental caries and its severity on the oral health-related quality of life (OHRQoL) of Kuwaiti preschool children and their caregivers. METHODS Participants were 4- and 5-year-old kindergarten children attending preselected public schools from one of the Governorates in Kuwait. Early childhood caries (ECC) was evaluated by clinical examinations and presented using decayed, missed, filled teeth/surface (dmft/dmfs). The clinical consequences of untreated dental caries were assessed using the pufa (pulp, ulcers, fistula, abscess) index for primary teeth. A structured questionnaire obtained demographic information of children and their caregivers. OHRQoL was assessed using the Arabic version of Early Childhood Oral Health Impact Scale (A-ECOHIS). RESULTS Among the 334 participants, 171 were kindergarten level-1 (KG1), and 163 were level-2 (KG2). The overall prevalence of dental caries was 78.9% for KG1 children and 67.4% for KG2 children. Decayed teeth were the main component for both dmft (84%) and dmfs (68%). The total mean (SD) pufa score was 0.54 (1.5), and about 19.2% of participants had at least one tooth with pufa > 0. A total of 207 A-ECOHIS were completed. Both family and child impact scores were significantly higher for children with a dmft score of 1 or more (p < 0.001) or with one or more pufa (p < 0.001). Child impact section scores were significantly higher with the increasing degrees of untreated caries (dt) (p = 0.004). CONCLUSION The severity of untreated dental caries and caries experience had a negative impact on the OHRQoL of Kuwaiti preschool children and their families. Using the pufa index had provided additional information about the effect of the caries severity on the OHRQoL than assessing the caries experience alone.

Abstract
This research focuses on the impacts of different meteorological parameters (temperature, humidity, rainfall, and evapotranspiration) on the transmission of Covid-19 in the administrative regions and provinces of Pakistan, i.e., Azad Jammu and Kashmir, Gilgit Baltistan, Khyber Pakhtunkhwa, Islamabad, Punjab, Sindh, and Balochistan from June 10, 2020, to August 31, 2021. This study analyzes the relation between Covid-19-confirmed cases and the meteorological parameters with the help of the autoregressive distributed lag model. In this research, additional tools (t-statistics, f-statistics, and time series analysis) are used for the motive of examining the linear relationship, the productivity of the model, and for the significant association between dependent and independent variables, lnccc and lnevp, lnhum, lnrain, lntemp, respectively. Values of t-statistics and f-statistics reveal that variables have a connection and individual significance for the model exist. Time series display that the Covid-19 spread increased from June 10, 2020, to August 31, 2021, in Pakistan. Temperature positively influenced the Covid-19-confirmed cases in all provinces of Pakistan in the long run. Evapotranspiration and rainfall influenced positively, while specific humidity influenced negatively on the confirmed Covid-19 cases in Azad Jammu Kashmir, Khyber Pakhtunkhwa, and Punjab. Specific humidity had a positive impact, while evapotranspiration and rainfall had the negative impact on the Covid-19-confirmed cases in Sindh and Balochistan. Evapotranspiration and specific humidity influenced positively, while rainfall influenced the Covid-19-confirmed cases negatively in Gilgit Baltistan. Evapotranspiration influenced positively, while specific humidity and rainfall influenced negatively on the Covid-19-confirmed cases in Islamabad.

Abstract
Circular RNAs (circRNAs) are ubiquitously expressed, covalently closed rings, produced by pre-mRNA splicing in a reversed order during post-transcriptional processing. Circularity endows 3'-5'-linked circRNAs with stability and resistance to exonucleolytic degradation which raises the question whether circRNAs may be relevant as potential therapeutic targets or agents. High stability in biological systems is the most remarkable property and a major criterion for why circRNAs could be exploited for a range of RNA-centred medical applications. Even though various biological roles and regulatory functions of circRNAs have been reported, their in-depth study is challenging because of their circular structure and sequence-overlap with linear mRNA counterparts. Moreover, little is known about their role in viral infections and in antiviral immune responses. We believe that an in-depth and detailed understanding of circRNA mediated viral protein regulations will increase our knowledge of the biology of these novel molecules. In this review, we aimed to provide a comprehensive basis and overview on the biogenesis, significance and regulatory roles of circRNAs in the context of antiviral immune responses and viral infections including hepatitis C virus infection, hepatitis B virus infection, hepatitis delta virus infection, influenza A virus infection, Epstein-Barr virus infection, kaposi's sarcoma herpesvirus infection, human cytomegalovirus infection, herpes simplex virus infection, human immunodeficiency virus infection, porcine epidemic diarrhoea virus infection, ORF virus infection, avian leukosis virus infection, simian vacuolating virus 40 infection, transmissible gastroenteritis coronavirus infection, and bovine viral diarrhoea virus infection. We have also discussed the critical regulatory role of circRNAs in provoking antiviral immunity, providing evidence for implications as therapeutic agents and as diagnostic markers.

Abstract
OBJECTIVES To assess the attitude and knowledge of family medicine practitioners (FMPs) towards the association between periodontal disease and obesity. MATERIALS AND METHODS A cross-sectional study was performed and a 13-item survey questionnaire was given to FMPs practicing in 12 different teaching hospitals in Karachi, Pakistan. The questions were aimed at exploring the knowledge of FMP's regarding the association of obesity and periodontal disease and their attitude towards the association of obesity and periodontal disease. Chi-square and Spearman co-efficient were conducted to compare subgroups and correlate factors with the knowledge score of FMPs. RESULTS A total of 314 questionnaires were completed (response rate = 92%). Median age of participants was 41 years and 57% were females. Almost 61% of FMPs answered all the knowledge questions correctly and 64% reported moderate understanding of the association between periodontal health and obesity. Nearly 73% FMPs inquired from obese patients regarding the periodontal disease and more than half (58%) refer patients to a dentist for evaluation. More than half of FMPs perform periodontal disease screening. Nearly all FMPs considered informing obese patients regarding periodontal disease as one of their roles. CONCLUSIONS FMP's play an important role in the early diagnosis, prevention and treatment of periodontal conditions in obese patients. More than two thirds of FMPs showed good knowledge of the association of obesity and periodontal disease. The attitudes of FMPs towards assessing and referring obese patients at a risk of having periodontal disease were reassuring.

Abstract
Abstract
Background
Local recurrence is a major concern in patients (pts) diagnosed with ductal carcinoma in situ (DCIS). Therefore, the need to identify pts at risk for DCIS recurrence is a significant priority. In invasive breast cancers, ER+/PR- subtype is considered a more aggressive tumor phenotype with poorer prognosis as compared to ER+/PR+ tumors. It is unclear whether this molecular subtype holds the same significance in pts with DCIS.
Methods
We designed an analysis to determine if a significant difference exists in the recurrence rates in pts with ER+/PR- DCIS when compared to ER+/PR+ tumors. Six hundred and ninety three pts diagnosed and treated for DCIS at Froedtert & MCW Clinical Cancer Center from Feb 2002-March 2015 were included in our study. Recurrence was defined as either non-invasive or invasive ipsilateral, contralateral or distant disease. Probabilities of recurrences were calculated using Kaplan-Meier estimator. Cox proportional hazards model was used to evaluate the effect of prognostic factors on DCIS recurrence.
Results
Median follow up was 5.2 years. Five year recurrence free survival (RFS) was 91% (95% CI 88.2-93.3) while estimated 7 year RFS was 86% (95% CI 81.9-89.2). Patient characteristics are shown in table below. Seventy five pts were found to have a recurrence during their follow-up. Most of the grade 1 tumors were ER+/PR+ whereas almost all of the ER-/PR- subtype were high grade tumors. ER+/PR- tumors were mainly intermediate and high grade (p <0.0001). Pts with ER-/PR- tumors had a significantly higher risk of recurrence (HR 3.7, 95% CI 1.9-7.2, p=0.0001) and those with ER+/PR- tumor subtype did not have a statistically significant difference in risk of recurrence when compared to ER+/PR+ tumors (HR 1.75, 95% CI 0.92-3.32, p=0.085). Pts who did not receive endocrine therapy for their ER+ DCIS had a significantly higher risk of recurrence as compared to those who received endocrine therapy (HR 2.2, 95% CI 1.23-3.92, p=0.0073). When compared to pts undergoing lumpectomy and radiation, pts undergoing lumpectomy alone had a significantly higher risk of recurrence (HR 2.5, 95% CI 1.32-4.93, p=0.005) whereas those who underwent mastectomy had a significantly lower risk of recurrence (HR 0.34, 95% CI 0.15-0.8, p=0.014).

Conclusion
ER+/PR- subtype was not a significant predictor of recurrence in DCIS patients. This finding is in contrast to the risk of recurrence and tumor aggressiveness seen in invasive breast cancers. Mastectomy and post lumpectomy radiation were associated with improved outcomes as was adjuvant endocrine therapy.

Abstract
This study was conducted for evaluation of existing MBBS curriculum (2002) of undergraduate medical education in Bangladesh. The specific objectives of this study were: i) to assess the subject wise course content coverage in the new MBBS curriculum, ii) to assess different examination system for evaluation of MBBS students, iii) to evaluate the effectiveness of teaching and learning activities under the curriculum, iv) to explore students opinions regarding improvement of new curriculum. This was a descriptive cross-sectional study. The study was conducted among the students of Dhaka medical colleges of Bangladesh in 2008. Data was collected by self administered structured questioner adopting convenient sampling method. About ninety percent students opined that the coverage of course content of subjects in the curriculum in Phase I was enough. In case of the subjects in phase II except community medicine more than four fifth of the students expressed their opinion about coverage of course content in the curriculum as enough. In case of phase III it was mentioned by most of the students that coverage of course content was enough. Study revealed that teaching methods were perceived suitable by about three fourth of the respondents, to achieve learning objectives. Most of the students expressed their positive views regarding practice of block posting teaching. More than three fourth of the students perceived that formative assessment was encouraging for students to become time bound learner and Structured Oral Examination (SOE) was fair on an average. Only 31(8.6%) of the respondents had opinion that Objective Structured Practical Examination (OSPE)/Objective Structured Clinical Examination (OSCE) was not well organized. About half of the students opined that 20% marks in written test should be allocated for Multiple Choice Question (MCQ). Students' suggestions regarding teaching were: there should be smaller group sessions; more interactive sessions; more clinical and practical sessions; more problem oriented sessions; more sessions with senior and experienced teachers; teachers should follow the curriculum properly; and should be well prepared for class. Regarding assessment suggestions were: written script of the formative examination should be returned to students with feedback; teachers should not be biased. Study recommended that training of the teachers on teaching methodology and assessment system is needed; teachers should provide feedback to the students according to the performance of the formative assessment at the individual level; to maintain the standards of assessment proper planning, designing, conduction and evaluation of assessment should be taken into consideration; subject wise review and updating is essential to make the curriculum more need based, user friendly and applicable considering context of Bangladesh.

Abstract
Acute experimental hydronephrosis induces increased output of renin from ipsilateral kidney. In most clinical presentation of unilateral hydronephrosis the patients are however, normotensive with normal circulating plasma renin activity. In consideration of this argument we undertook this prospective study of ipsilateral renal vein renin activity in children with congenital Pelvic Ureteric Junction Obstruction (PUJO) and compared with other wise normal children. In this prospective cross-sectional study, started from July 99 to June 2001, twenty patients, age upto 12 years, with unilateral hydronephrosis and in control group ten patients without hydronephrosis were taken. 2ml blood was taken from the renal vein in study group and from infrarenal portion of inferior vena cava during exploratory laparotomy from the control group. All the patients had advanced grade of hydronephrosis and two patients (13%) had mild hypertension. In this study the mean plasma renin activity (PRA) was 45.58 ng/ml/hr (range: 11.69-67.56 ng/ml/hr) in study group. The mean PRA in control group was 5.9ng/ml/hr. The result of study group was significantly higher than normal (P value 0.0003). In Bangladesh we are doing more conservative kidney preserving surgery for PUJO, but need long term follow up of the patients undergoing surgery for PUJO in childhood for potential of developing renin-angiotensin induced hypertension in later life.

Abstract
Sea bream broodstock were immunised 1 or 2 months before spawning with a novel photobacteriosis vaccine. Sixty-seven-day-old larvae (mean weight 22.3 mg) originating from immunised and non-immunised parents were experimentally infected with the Photobacterium damsela subsp. piscicida (Phdp). Larvae from immunised fish showed delayed onset and lower mortality (66.67%) compared with larvae from control fish (80%). Eighty-nine-day-old larvae (mean weight 162.2 mg) from both groups were bath vaccinated with Phdp and Escherichia coli lipopolysaccharides (LPS) and larval samples were collected for measurement of humoral parameters. Larvae vaccinated with Phdp and LPS showed significantly higher anti-protease activity, lysozyme activity and total immunoglobulin compared to the controls. One-hundred-and-twenty-day-old larvae (mean weight 297.85 mg) from both parental groups were challenged with (LD70) virulent Phdp bacterial cells. Vaccinated larvae from both groups showed significantly less mortality compared to the respective controls. The RPS values of larvae from immunised parents vaccinated with Phdp and LPS was 95.83% and 72.22%, respectively. The RPS values of larvae from non-immunised parents vaccinated with Phdp and LPS was 62.5% and 70.83%, respectively. Results are discussed with respect to the beneficial effect of broodstock immunisation prior to spawning and the immunisation of larvae on their survival against photobacteriosis.

Abstract
Immunisation of sea bream (Sparus aurata L.) broodstock with a novel vaccine mixture of Photobacterium damsela subsp. piscicida SK7 (Phdp) was performed during the period of egg development and the changes in specific and non-specific humoral immune parameters were measured. Total immunoglobulin level, specific antibody titre, anti-protease activity and lysozyme activity were significantly higher in immunised parents compared to the control. After spawning significantly higher anti-protease activity, lysozyme activity and total immunoglobulin level were detected in the eggs from immunised parents. Specific antibody titres against Phdp were only detected in the eggs from the immunised parents. The larvae from immunised parents also expressed significantly higher levels of specific and non-specific humoral immune parameters compared to the controls. A small amount of total immunoglobulin was detected in larvae decreasing gradually until day 8 post-hatching and then an increase was measured in larvae from immunised parents, whereas no immunoglobulin was detected at days 4, 6 and 8 in larvae from non-immunised parents. The specific antibody titre against Phdp was detected only in larvae from immunised broodstock until day 14 post-hatching. The higher humoral immune parameters in eggs and larvae from immunised parents in comparison to eggs and larvae from non-immunised parents, suggest transfer of maternal specific and non-specific immune factors.

Abstract
Photobacterium damsela subsp. piscicida, the causative agent of fish pasteurellosis, was grown in vivo. Bacterial cells and extracellular products (ECPs) were analysed via electrophoresis and immunoblot analysis, using specific sea bass antisera. Growth in vivo induced the synthesis of unique bacterial cell proteins at > 206, 206, 21.3, 18, 7.6 and < 7.6 kDa. Sea bass serum raised against live bacterial cells of the pathogen and especially a sea bass serum raised against formalin-inactivated bacterial cells grown in a specific novel medium recognized the novel antigens at > 206 (associated with iron sequestration), 21.3, 7.6 and < 7.6 kDa, suggesting that the latter medium conserves the synthesis of natural bacterial cell proteins in vitro. In vivo growth of the pathogen induced the synthesis of more toxic ECPs in comparison with in vitro growth and an inverse correlation between total protein concentration in the ECPs and toxicity per unit of protein was observed. Substrate-polyacrylamide electrophoresis revealed the presence of in vivo synthesized ECPs of the pathogen (proteases) at 175, 132, < 79 and 48.3 kDa. Histological examination of tissues isolated from fish injected with these ECPs revealed inflammatory and necrotic lesions in the spleen, liver, head kidney, intestine and heart as soon as 48 h post-introduction of the ECPs.

Abstract
PURPOSE To reduce the incidence of nephrectomy or hydronephrosis in children. MATERIALS AND METHODS From September 1998 to October 2000, we treated 58 patients with hydronephrosis; their ages ranged from 35 days to 11 years (mean age 4 years 7 months). All patients were subjected to a DTPA renogram with split function. In 12 patients (study group), kidney function was less than 10 % (range 0 - 10 %). Initially, nephrostomy was carried out in all 12 patients followed by Anderson-Hyne's pyeloplasty after 4 - 6 weeks. Postoperatively renal USG, urine r/m/e & c/s (routine and microscopic examination and culture and sensitivity test), blood urea, serum creatinine were assessed and DMSA scan and DTPA renogram with split functions were carried out in all patients. RESULTS In the study group, all 12 patients showed improvement of renal function (more than 10 %) after nephrostomy and in all of them pyeloplasty was subsequently carried out within 4 - 6 weeks. There were no significant pre-, peri- or postoperative complications. CONCLUSIONS Contrary to common practice we do not recommend nephrectomy for hydronephrotic kidneys which show < 10 % of renal function on renogram. The renal functional status improves significantly after a preliminary nephrostomy, thus avoiding the need for a straightforward nephrectomy in children along with all the possible long-term effects of a single kidney.
