Gender-based incidence, recovery period, and mortality rate of COVID-19 among the population of district Attock, Pakistan / Incidência baseada em gênero, período de recuperação e taxa de mortalidade de COVID-19 entre a população do distrito de Attock, Paquistão

Abstract COVID-19 is reported as an extremely contagious disease with common symptoms of fever, dry cough, sore throat, and tiredness. The published literature on incidence and gender-wise prevalence of COVID-19 is scarce in Pakistan. Therefore, the present study was designed to compare the distribution, incubation period and mortality rate of COVID-19 among the male and female population of district Attock. The data were collected between 01 April 2020 and 07 December 2020 from the population of district Attock, Pakistan. A total of 22,962 individuals were screened and 843 were found positive for RT-qPCR for SARS-CoV-2. The confirmed positive cases were monitored carefully. Among the positive cases, the incidence of COVID-19 was 61.7% among males and 38.2% among females. The average recovery period of males was 18.89±7.75 days and females were 19±8.40 days from SARS-CoV-2. The overall mortality rate was 8.06%. The death rate of male patients was significantly higher (P<0.05) compared to female patients. Also, the mortality rate was higher (P<0.05) in male patients of 40-60 years of age compared to female patients of the same age group. Moreover, the mortality rate significantly increased (P<0.05) with the increase of age irrespective of gender. In conclusion, the incidence and mortality rate of COVID-19 is higher in males compared to the female population. Moreover, irrespective of gender the mortality rate was significantly lower among patients aged <40 years.

Evaluation of economic loss caused by Indian crested porcupine (Hystrix indica) in agricultural land of district Muzaffarabad, Azad Jammu and Kashmir, Pakistan / Avaliação da perda econômica causada pelo porco-espinho de crista indiano (Hystrix indica) em terras agrícolas dos distritos de Muzaffarabad, Azad Jammu e Caxemira, Paquistão

Abstract The Indian crested porcupine (Hystrix indica) is a vertebrate pest of agricultural lands and forest. The study was aimed to report the damage to local crops by the Indian crested porcupine (Hystrix indica) in the Muzaffarabad District. A survey was conducted to identify the porcupine-affected areas and assess the crop damage to the local farmers in district Muzaffarabad Azad Jammu and Kashmir (AJK) from May 2017 to October 2017. Around 19 villages were surveyed, and a sum of 191 semi-structured questionnaires was distributed among farmers. Crop damage was found highest in village Dhanni where a porcupine destroyed 175 Kg/Kanal of the crops. Regarding the total magnitude of crop loss, village Danna and Koomi kot were the most affected areas. More than half (51.8%) of the respondents in the study area suffered the economic loss within the range of 101-200$, and (29.8%) of the people suffered losses in the range of 201-300$ annually. Among all crops, maize (Zea mays) was found to be the most damaged crop ranging between 1-300 Kg annually. In the study area, porcupine also inflicted a lot of damages to some important vegetables, including spinach (Spinacia oleracea), potato (Solanum tuberosum) and onion (Allium cepa). It was estimated that, on average, 511Kg of vegetables are destroyed by porcupine every year in the agricultural land of Muzaffarabad. It was concluded that the Indian crested porcupine has a devastating effect on agriculture which is an important source of income and food for the local community. Developing an effective pest control strategy with the help of the local government and the Wildlife department could help the farmers to overcome this problem.

Resumo O porco-espinho de crista indiano (Hystrix indica) é uma praga vertebrada de terras agrícolas e florestais. No estudo atual, o dano às plantações locais pelo porco-espinho de crista indiano (Hystrix indica) foi relatado pela primeira vez no distrito de Muzaffarabad. O estudo foi projetado para investigar a perda econômica causada pelo porco-espinho de crista indiano (Hystrix indica) nos distritos de Muzaffarabad, Azad Jammu e Caxemira (AJK) de maio de 2017 a outubro de 2017. Um estudo baseado em pesquisa foi conduzido para identificar as áreas afetadas por porcos-espinhos e avaliar os danos às colheitas para os agricultores locais. Cerca de 19 aldeias foram pesquisadas e um total de 191 questionários semiestruturados foi distribuído entre os agricultores. Os danos às colheitas foram encontrados mais intensamente na aldeia Dhanni, onde um porco-espinho destruiu 175 kg / Kanal das colheitas. Em relação à magnitude total da perda de safra, as aldeias Danna e Koomi Kot foram as áreas mais afetadas. Mais da metade (51,8%) dos entrevistados na área de estudo sofreu perdas econômicas na faixa de 101-200 $, e 29,8% das pessoas sofreram perdas na faixa de 201-300 $ anualmente. Entre todas as culturas, o milho (Zea mays) foi considerado a cultura mais danificada, variando entre 1-300 kg anualmente. Na área de estudo, o porco-espinho também causou muitos danos a alguns vegetais importantes, incluindo espinafre (Spinacia oleracea), batata (Solanum tuberosum) e cebola (Allium cepa). Estimou-se que, em média, 511 kg de vegetais são destruídos pelo porco-espinho todos os anos nas terras agrícolas de Muzaffarabad. Concluiu-se que o porco-espinho de crista indiano tem um efeito devastador na agricultura, que é importante fonte de renda e alimento para a comunidade local. O desenvolvimento de uma estratégia eficaz de controle de pragas com a ajuda do governo local e do Departamento de Vida Selvagem pode ajudar os agricultores a superar esse problema.

A comparative study to evaluate the effects of antibiotics, plant extracts and fluoride-based toothpaste on the oral pathogens isolated from patients with gum diseases in Pakistan / Um estudo comparativo para avaliar os efeitos de antibióticos, extratos vegetais e creme dental à base de flúor sobre os patógenos orais isolados de pacientes com doenças gengivais no Paquistão

Abstract Oral diseases caused by various microorganisms are common around the world. Scientific research has now been focusing on novel medicines to overcome bacterial resistance and antibiotics side effects; therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts (Ajuga bracteosa and Curcuma longa) versus the bacterial pathogens isolated from the human oral cavity. A total of 130 samples were collected from Khyber Teaching Hospital Peshawar, Pakistan, among those 27 species isolated, and eight bacterial species were identified from the samples. Among all the bacterial species, Staphylococcus aureus (29.62%) and Proteus mirabilis (22.2%) were found to be more prevalent oral pathogens. In comparison, the least pervasive microbes were Proteus vulgaris, Shigella sonnei, Escherichia coli and Aeromonas hydrophila. The study also suggested that dental problems were more prevalent in males (41-50 years of age) than females. Among the eight antibiotics used in the study, the most promising results were shown by Foxicillin against A. hydrophila. The survey of TP1 revealed that it showed more potent antagonist activity against Proteus vulgaris as compared TP2 and TP3 that might be due to the high content of fluoride. The Curcuma longa showed more significant activity than Ajuga bracteosa (Stem, leaves and root) extracts. The data obtained through this study revealed that antibiotics were more effective for oral bacterial pathogens than toothpaste and plant extracts which showed moderate and low activity, respectively. Therefore, it is suggested that the active compounds in individual medicinal plants like Curcuma longa and Ajuga bracteosa could replace the antibiotics when used in daily routine as tooth cleansers or mouth rinses.

Resumo As doenças bucais causadas por vários microrganismos são comuns em todo o mundo. A pesquisa científica agora tem se concentrado em novos medicamentos para superar a resistência bacteriana e os efeitos colaterais dos antibióticos; portanto, o presente estudo foi desenhado para avaliar a eficácia de certos antibióticos, pasta de dente e extratos de plantas medicinais (Ajuga bracteosa e Curcuma longa) contra os patógenos bacterianos isolados da cavidade oral humana. No total, 130 amostras foram coletadas do Khyber Teaching Hospital Peshawar, Paquistão, entre essas, 27 espécies foram isoladas e oito espécies bacterianas foram identificadas a partir das amostras. Entre todas as espécies bacterianas, Staphylococcus aureus (29.62%) e Proteus mirabilis (22.2%) foram os patógenos orais mais prevalentes. Em comparação, os micróbios menos difundidos foram Proteus vulgaris, Shigella sonnei, Escherichia coli e Aeromonas hydrophila. O estudo também sugeriu que os problemas dentários eram mais prevalentes em homens (41-50 anos de idade) do que em mulheres. Entre os oito antibióticos usados ​​no estudo, os resultados mais promissores foram mostrados pelo Foxicillin contra A. hydrophila. A pesquisa de TP1 revelou que ele mostrou atividade antagonista mais potente contra Proteus vulgaris em comparação a TP2 e TP3, o que pode ser devido ao alto teor de flúor. A Curcuma longa apresentou atividade mais significativa em relação aos extratos de Ajuga bracteosa (caule, folhas e raiz). Os dados obtidos neste estudo revelaram que os antibióticos foram mais eficazes para os patógenos bacterianos orais do que os dentifrícios e os extratos vegetais que apresentaram atividade moderada e baixa, respectivamente. Portanto, sugere-se que os compostos ativos em plantas medicinais individuais como Curcuma longa e Ajuga bracteosa possam substituir os antibióticos quando usados ​​na rotina diária como limpadores de dentes ou enxaguatórios bucais.

Um total de 22.962 indivíduos foi selecionado, e 843 foram considerados positivos para RT-qPCR para SARS-CoV-2. Os casos positivos confirmados foram monitorados cuidadosamente. Entre os casos positivos, a incidência de Covid-19 foi de 61,7% no sexo masculino e 38,2% no feminino. O período médio de recuperação dos homens foi de 18,89 ± 7,75 dias e das mulheres 19 ± 8,40 dias do SARS-CoV-2. A mortalidade geral foi de 8,06%. A taxa de mortalidade de pacientes do sexo masculino foi significativamente maior (P 0,05) em comparação com pacientes do sexo feminino. Além disso, a taxa de mortalidade foi maior (P 0,05) em pacientes do sexo masculino com 40-60 anos de idade em comparação com pacientes do sexo feminino da mesma faixa etária. Além disso, a taxa de mortalidade aumentou significativamente (P 0,05) com o aumento da idade, independentemente do sexo. Em conclusão, a incidência e a taxa de mortalidade de Covid-19 são maiores no sexo masculino em comparação com a população feminina. E também, independentemente do sexo, a taxa de mortalidade foi significativamente menor entre os pacientes com idade 40 anos.

A new approach to actinic folliculitis: prophylactic narrowband ultraviolet B phototherapy.

BACKGROUND: We have observed an increasing number of patients referred to the Scottish Photobiology Service (SPS), who were later diagnosed with actinic folliculitis (AF) and had positive phototesting results. Treatment options for AF are limited, with only a few reports in the literature. The use of prophylactic narrowband ultraviolet B (NB-UVB) phototherapy for AF has not previously been described, and we report on this for the first time. AIM: To analyse the clinical characteristics, phototesting results and responses to treatment for patients with AF diagnosed by the SPS. METHODS: We undertook a retrospective review over 10 years of all case notes of patients who were assessed and diagnosed with AF through the SPS, based at the Photobiology Unit, Dundee, UK. RESULTS: All 10 patients were women. Mean age of onset was 25 years and mean time to referral for investigation was 7 years. The commonest site involved was the face, with the main clinical feature being monomorphic pustules appearing after sunlight exposure. The eruption could be provoked with iterative doses of broadband UVA irradiation in five patients. All patients were offered photoprotective advice and prophylactic NB-UVB phototherapy. Five patients proceeded with phototherapy; four of these completed the desensitization course and all four reported either a delay in symptom onset or total prevention of rash induction, with complete efficacy of desensitization maintained for 3 years in one patient. CONCLUSION: We demonstrate the successful use of UVA provocation testing as a diagnostic tool in AF. Additionally, we recommend the use of prophylactic NB-UVB phototherapy in AF as an effective and well-tolerated approach.

Diabetes and onset of natural menopause: results from the European Prospective Investigation into Cancer and Nutrition.

STUDY QUESTION: Do women who have diabetes before menopause have their menopause at an earlier age compared with women without diabetes? SUMMARY ANSWER: Although there was no overall association between diabetes and age at menopause, our study suggests that early-onset diabetes may accelerate menopause. WHAT IS KNOWN ALREADY: Today, more women of childbearing age are being diagnosed with diabetes, but little is known about the impact of diabetes on reproductive health. STUDY DESIGN, SIZE, DURATION: We investigated the impact of diabetes on age at natural menopause (ANM) in 258 898 women from the European Prospective Investigation into Cancer and Nutrition (EPIC), enrolled between 1992 and 2000. PARTICIPANTS/MATERIALS, SETTING, METHODS: Determinant and outcome information was obtained through questionnaires. Time-dependent Cox regression analyses were used to estimate the associations of diabetes and age at diabetes diagnosis with ANM, stratified by center and adjusted for age, smoking, reproductive and diabetes risk factors and with age from birth to menopause or censoring as the underlying time scale. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, no association between diabetes and ANM was found (hazard ratio (HR) = 0.94; 95% confidence interval (CI) 0.89-1.01). However, women with diabetes before the age of 20 years had an earlier menopause (10-20 years: HR = 1.43; 95% CI 1.02-2.01, <10 years: HR = 1.59; 95% CI 1.03-2.43) compared with non-diabetic women, whereas women with diabetes at age 50 years and older had a later menopause (HR = 0.81; 95% CI 0.70-0.95). None of the other age groups were associated with ANM. LIMITATIONS, REASONS FOR CAUTION: Strengths of the study include the large sample size and the broad set of potential confounders measured. However, results may have been underestimated due to survival bias. We cannot be sure about the sequence of the events in women with a late age at diabetes, as both events then occur in a short period. We could not distinguish between type 1 and type 2 diabetes. WIDER IMPLICATIONS OF THE FINDINGS: Based on the literature, an accelerating effect of early-onset diabetes on ANM might be plausible. A delaying effect of late-onset diabetes on ANM has not been reported before, and is not in agreement with recent studies suggesting the opposite association.

Comparison of three commercial RT-PCR systems for the detection of respiratory viruses.

BACKGROUND: Due to the insensitivity of rapid tests for respiratory viruses, nucleic acid amplification tests are quickly becoming the standard of care. OBJECTIVES AND STUDY DESIGN: The performance of the FilmArray Respiratory Panel (RP) and Verigene RV+ (RV+) were compared in a retrospective analysis of 89 clinical specimens previously determined to be positive for the following viruses by our test of record, Prodesse (Pro): influenza A (29, FluA), influenza B (13, FluB), respiratory syncytial virus (12, RSV), human metapneumovirus (10, hMPV), parainfluenza (14, PIV), and adenovirus (10, AdV). Samples positive for influenza A, B or RSV were tested by both methods, while the remainder were tested by RP only. True positives were defined as positive by two or more assays. RESULTS: Limit of detection (LOD) analyses demonstrated Pro had the lowest LOD for all FluA strains tested, PIV1, PIV2 and AdV; RV+ had the lowest LOD for FluB; and RP had the lowest LOD for RSV, PIV3 and hMPV. Of the 55 samples tested by RV+, all 54 true positive samples were positive by RV+. Of the 89 samples tested by RP, 85 of the 88 true positive samples were positive by RP. From these results, the overall sensitivities for influenza A, B and RSV were 100% and 98% for RV+ and RP, respectively. The overall sensitivity of RP for all viruses was 97%. CONCLUSIONS: In summary, these systems demonstrated excellent performance. Furthermore, each system has benefits which will ensure they will all have a niche in a clinical laboratory.

Tumour-related factors and prognosis in breast cancer detected by screening.

BACKGROUND: Breast cancer detected by screening has an unexplained prognostic advantage beyond stage shift compared with cancers detected clinically. The aim was to investigate biological factors in invasive breast cancer, with reference to mode of detection and rate of death from breast cancer. METHODS: Histology, oestrogen receptor α and ß, progesterone receptor, human epidermal growth factor receptor (HER) 2, cyclin D1, p27, Ki-67 and perinodal growth were analysed in 466 tumours from a prospective cohort, the Malmö Diet and Cancer Study. Using logistic regression, odds ratios were calculated to investigate the relationship between tumour characteristics and mode of detection. The same tumour factors were analysed in relation to standard prognostic features. Death from breast cancer was analysed using Cox regression with adjustments for standard tumour factors; differences following adjustment were analysed by means of Freedman statistics. RESULTS: None of the biological tumour characteristics varied with mode of detection of breast cancer. After adjustment for age, tumour size, axillary lymph node involvement (ALNI) and grade, women with cancer detected clinically had an increased risk of death from breast cancer (hazard ratio 2·48, 95 per cent confidence interval 1·34 to 4·59), corresponding to a 37·2 per cent difference compared with the unadjusted model. Additional adjustment for biological tumour factors studied caused only minor changes. CONCLUSION: None of the biological tumour markers investigated explained the improved prognosis in breast cancer detected by screening. None of the factors was related to ALNI, suggesting that other mechanisms may be responsible for tumour spread.

Combined effect of low-penetrant SNPs on breast cancer risk.

BACKGROUND: Although many low-penetrant genetic risk factors for breast cancer have been discovered, knowledge about the effect of multiple risk alleles is limited, especially in women <50 years. We therefore investigated the association between multiple risk alleles and breast cancer risk as well as individual effects according to age-approximated pre- and post-menopausal status. METHODS: Ten previously described breast cancer-associated single-nucleotide polymorphisms (SNPs) were analysed in a joint European biobank-based study comprising 3584 breast cancer cases and 5063 cancer-free controls. Genotyping was performed using MALDI-TOF mass spectrometry, and odds ratios were estimated using logistic regression. RESULTS: Significant associations with breast cancer were confirmed for 7 of the 10 SNPs. Analysis of the joint effect of the original 10 as well as the statistically significant 7 SNPs (rs2981582, rs3803662, rs889312, rs13387042, rs13281615, rs3817198 and rs981782) found a highly significant trend for increasing breast cancer risk with increasing number of risk alleles (P-trend 5.6 × 10(-20) and 1.5 × 10(-25), respectively). Odds ratio for breast cancer of 1.84 (95% confidence interval (CI): 1.59-2.14; 10 SNPs) and 2.12 (95% CI: 1.80-2.50; 7 SNPs) was seen for the maximum vs the minimum number of risk alleles. Additionally, one of the examined SNPs (rs981782 in HCN1) had a protective effect that was significantly stronger in premenopausal women (P-value: 7.9 × 10(-4)). CONCLUSION: The strongly increasing risk seen when combining many low-penetrant risk alleles supports the polygenic inheritance model of breast cancer.

Non-caseating granulomas in patients after the diagnosis of cancer: clinical characteristics and outcome.

BACKGROUND: The association between cancer and non-caseating granulomas is controversial. The aim of this study is to describe the clinical characteristics and outcome of a cohort of patients found to have non-caseating granulomas following the diagnosis of cancer. METHODS: Retrospective review of medical records. RESULTS: There were 30 patients with non-caseating granulomas following the diagnosis of cancer. There were 21 females and 14 patients were African Americans. Breast, lung, and head and neck cancers were the most common malignancies. The time between the diagnosis of cancer and non-caseating granulomas was a mean of 27.6 months (range 3 to 245 months). New mediastinal lymphadenopathy were present in 29 patients and pulmonary infiltrates or nodules were detected in 15 patients. All patients who underwent FDG-PET scan (n=18) had FDG avid findings with a mean SUV of 6.8 (range 2.8-19.4). Non-caseating granulomas were diagnosed by mediastinoscopy (12 patients), EBUS-FNA (6 patients), surgical thoracic biopsy (3 patients), transbronchial biopsy (2 patients), and other biopsies (7 patients). Patients were followed for a mean of 32.7 months (range 6-98 months) and 3 patients developed recurrence of the primary cancer. CONCLUSION: Non-caseating granulomas should be considered in patients with cancer who develop lymphadenopathy or pulmonary nodules. Recurrence of cancer should not always be assumed, and tissue diagnosis is essential.

Anti-TNF-alpha agents are less effective for the treatment of rheumatoid arthritis in current smokers.

OBJECTIVES: To assess if smoking status at the time of commencing an anti-TNF-alpha agent for rheumatoid arthritis (RA) reduces the likelihood of achieving at least a moderate response on the European League Against Rheumatism (EULAR) response criteria at 3-month assessment. METHODS: All patients with RA treated with their first anti-TNF-alpha agent at the Department of Rheumatology, Derby Hospital NHS Trust between April 2001 and October 2008 were included in this retrospective case control study. Information about age, gender, disease duration, body mass index, smoking status (current smoker, ex-smoker, and nonsmoker), comorbidities, oral prednisolone use, and 28 joint 4 variables disease activity score (DAS28) at the time of commencing an anti-TNF-alpha agent was recorded. Details of rheumatoid factor (RF) and past and present disease modifying antirheumatic drugs were recorded. A case control study was carried out to examine possible baseline predictors of treatment effects at the 3-month assessment. RESULTS: Results were available for 395 patients at 3-month assessment. According to the EULAR response criteria 42 patients failed to show at least a moderate response. After adjusting for confounders using multivariate analysis, current smoking at the time of commencing an anti-TNF-alpha agent reduced the chance of achieving at least a moderate response on the EULAR response criteria when compared with nonsmokers (aOR [95% CI] 0.20 [0.05-0.83], P = 0.03). CONCLUSIONS: RA patients who smoke are less likely to respond to an anti-TNF-alpha agent.

Parity in relation to survival following breast cancer.

AIM: The present study examines the association between parity and survival following breast cancer diagnosis. METHODS: Medical records of 4453 women diagnosed with breast cancer in Malmö, Sweden, between 1961 and 1991 were analysed. All women were followed until 31 December 2003, using the Swedish Cause-of-Death Registry. Breast cancer specific mortality rate was calculated in different levels of parity. Corresponding relative risks, with 95% confidence intervals (CI), were obtained using Cox's proportional hazards analysis. All analyses were adjusted for potential prognostic factors and stratified for age, menopausal status and diagnostic period. RESULTS: As compared to women with one child, nulliparity (RR 1.27: 95% CI 1.09-1.47), and high parity (four or more children) (1.49: 1.20-1.85) were positively associated with a high mortality from breast cancer. When adjusted for potential confounders, the association was only statistically significant for high parity (1.33: 1.07-1.66). In the analyses stratified on age and menopausal status, there was a similar positive association between high parity and breast cancer death in all strata, although only statistically significant among women older than 45 years of age or postmenopausal. Nulliparity was associated with breast cancer death in women that were younger than 45 years of age (1.28: 0.79-2.09) or premenopausal (1.30: 0.95-1.80), but these associations did not reach statistical significance. There was no association between nulliparity and breast cancer death in women older than 45 years of age or postmenopausal. All associations were similar in analyses stratified for diagnostic period. CONCLUSION: Women with four or more children have a poor breast cancer survival as compared to women with one child.

The importance of the baseline Disease Activity Score 28 in determining responders and non-responders to anti-TNF in UK clinical practice.

OBJECTIVES: The NICE re-appraisal of anti-TNF requires demonstration of ongoing response, making the baseline 28-joint Disease Activity Score (DAS28) crucially important. A retrospective analysis of all RA patients on their first anti-TNF determined predictive factors for those classified as non-responders at 6 months according to current NICE guidelines. METHODS: The patients were divided into responders (DAS28 dropped by >1.2) and non-responders. These groups were compared for demographics, DAS28 at the two pre-assessments 1 month apart and at baseline. Exposure to intramuscular, oral and IA steroids in the 3 months period before the baseline DAS28 was recorded. RESULTS: At 6-month assessment in 256 patients, 82.8% were responders with no demographic differences between them and non-responders. Although the first pre-assessment score was not significantly different (6.8 vs 6.6), the second pre-assessment score (7.1 vs 6.7) and the baseline DAS (7.2 vs 6.3) were lower in the non-responders (P < 0.04 and P < 0.001, respectively). Comparing the differences in DAS28 from the first pre-assessment to baseline, the responders had increased by 0.4, and the non-responders had decreased by 0.4, (P < 0.001). If the first pre-assessment score had been taken as the baseline DAS28, then 9.4% of responders would be re-classified as non-responders, and 31.8% of non-responders would be re-classified as responders. The proportion of patients who had steroid treatment within the 3 months period before the baseline DAS28 did not differ significantly between the responders and non-responders (34% vs 41%, P = 0.38). CONCLUSION: Baseline DAS28 is critical in classifying responders at the 6-month assessment.
