Studies on parasitic prevalence in pet birds from Punjab, Pakistan / Estudos de prevalência parasítica em pássaros de estimação de Punjab, Paquistão

During this one year study, blood and fecal samples of doves (Zenaida asiatica), ducks (Anas platyrhynchos), pigeons (Columba livia), partridges (Alectoris chukar), turkeys (Meleagris gallopavo) and goose (Chen caerulescens) were collected to assess the parasitic prevalence in these birds. The birds were kept at Avian Conservation and Research Center, Department of Wildlife and Ecology, University of Veterinary and Animal Sciences, Lahore. All these avian species were kept in separate cages and their entire body was inspected on regularly basis to record external parasites. For internal parasites, 100 blood and 100 fecal samples for each species were analyzed. During present study, two species of ectoparasites i.e. fowl ticks (Args persicus) and mite (Dermanyssus gallinae) while 17 species of endoparasites; three from blood and 14 from fecal samples were identified. Prevalence of blood parasites was Plasmodium juxtanucleare 29.3%, Aegyptinella pullorum 15% and Leucoctoyzoon simond 13%. Parasitic species recorded from fecal samples included 6 species of nematodes viz. Syngamus trachea with parasitic prevalence of 50%, Capillaria anatis 40%, Capillaria annulata 37.5%, Heterakis gallinarum 28.3%, Ascardia galli 24% and Allodpa suctoria 2%. Similarly, two species of trematodes viz. Prosthogonimus ovatus having parasitic prevalence of 12.1% and Prosthogonimus macrorchis 9.1% were also recorded from fecal samples of the birds. Single cestode species Raillietina echinobothrida having parasitic prevalence of 27% and 3 protozoan species i.e. Eimeria maxima having prevalence 20.1%, Histomonas meleagridis 8% and Giardia lamblia 5.3% were recorded. In our recommendation, proper medication and sanitation of the bird's houses and cages is recommended to avoid parasites.

Optimized biotransformation of acid-treated water melon peel hydrolyzate into ethanol

Abstract Today, global focus of research is to explore the solution of energy crisis and environmental pollution. Like other agricultural countries, bulk quantities of watermelon peels (WMP) are disposed-off in environment as waste in Pakistan and appropriate management of this waste is the need of hour to save environment from pollution. The work emphasizes the role of ethanologenic yeasts to utilize significant sugars present in WMP for low-cost bioethanol fermentation. Dilute hydrochloric acid hydrolysis of WMP was carried out on optimized conditions employing RSM (response surface methodology) following central composite design (CCD). This experimental design is based on optimization of ethanologenesis involving some key independent parameters such as WMP hydrolysate and synthetic media ratio (X1), incubation temperature (X2) and incubation temperature (X3) for maximal ethanol yield exploiting standard (Saccharomyces cerevisiae K7) as well as experimental (Metchnikowia cibodasensisY34) yeasts. The results revealed that maximal ethanol yields obtained from S. cerevisiae K7 was 0.36±0.02 g/g of reducing sugars whereas M. cibodasensisY34, yielded 0.40±0.01 g ethanol/g of reducing sugars. The yeast isolate M. cibodasensisY34 appeared as promising ethanologen and embodies prospective potential for fermentative valorization of WMP-to-bioethanol.

Resumo Hoje, o foco global da pesquisa é explorar a solução da crise energética e da poluição ambiental. Como em outros países agrícolas, grandes quantidades de cascas de melancia (WMP) são descartadas como resíduos no meio ambiente no Paquistão, mas a gestão adequada desses resíduos é a mais recente solução para salvar o meio ambiente da poluição. O trabalho enfatiza o papel das leveduras etanologênicas para utilizar açúcares significativos presentes no WMP para fermentação de bioetanol de baixo custo. A hidrólise de ácido clorídrico diluído de WMP foi realizada em condições otimizadas empregando RSM (metodologia de superfície de resposta) e seguindo o projeto de composto central (CCD). Este projeto experimental é baseado na otimização da etanologenesis envolvendo alguns parâmetros independentes importantes, como hidrolisado de WMP e razão de meio sintético (X1), temperatura de incubação (X2) e temperatura de incubação (X3) para rendimento máximo de etanol explorando o padrão (Saccharomyces cerevisiae K7) também como leveduras experimentais (Metchnikowia cibodasensis Y34). Os resultados revelaram que os rendimentos máximos de etanol obtidos a partir de S. cerevisiae K7 foi de 0,36 ± 0,02 g / g de açúcares redutores, enquanto M. cibodasensis Y34 rendeu 0,40 ± 0,01 g de etanol / g de açúcares redutores. O isolado de levedura M. cibodasensis Y34 apareceu como um etanologeno promissor e incorpora um potencial prospectivo para a valorização fermentativa de WMP em bioetanol.

Positive Pressure and Negative Pressure Irrigation Dynamics with Different Needle Designs Using Computational Fluid Dynamics

@#This study aimed to investigate the irrigation dynamics of the positive pressure side-vented (SV) needle, EndoVac (micropores) needle and modified apical negative pressure (mANP) open-ended needle using computational fluid dynamics (CFD). A simulation of a prepared root canal (conical frustum) of 15 mm length with an apical diameter of 0.40 mm following Protaper F4 apical preparation was created using three-dimensional (3D) CAD software. The 3D simulated needle of SV 30G needle, EndoVac with micropores needle and mANP, 30G flat open-ended needle were also created. The irrigation dynamics were evaluated through transient CFD simulations. In addition, the irrigation dynamics of mANP at 0.2 mm, 0.5 mm, and 1.0 mm short from the working length were also assessed. The EndoVac and mANP showed negative apical static pressure and streamline patterns able to reach the apical region, thus indicating negligible extrusion. Meanwhile, SV showed positive apical static pressure and almost nonexistent streamlines beyond the needle tip. The SV showed the highest wall shear stress (WSS) magnitude of 1030Pa whereas Endovac (161 Pa) and mANP1 (258 Pa). However, SV revealed lower average WSS (10 Pa) compared to mANP1 (13 Pa) and mANP2 (11 Pa). This is due to SV developed a localised maximum WSS opposite the open vent area only therefore, uneven distribution of WSS. The EndoVac system developed a localised maximum WSS in the pair of micropores furthest away from the apical. CFD analysis of the EndoVac, mANP and SV showed different technique approach, needle design and needle depths insertion affect the irrigation dynamics pattern and magnitude.

A Systematic Review on Effectiveness of Nicotine-Based and NonNicotine Based Drug Delivery System for Smoking Cessation Among the Elderly

@#Introduction: Smoking is associated with a higher risk of mortality, especially in smokers with cardiovascular and respiratory diseases. Smoking cessation remains the most effective approach in reducing smoking-related illness risks at all ages. For elderly smokers, smoking cessation has been proved to prolong life expectancy and reduce the risk of stroke and ischemic heart disease. However, a wide selection of smoking cessation medications makes prescribing challenging, especially among elderly smokers. Inability to recommend the best treatment may reduce the smoking cessation success rate in the elderly. Therefore, this study compares the effectiveness of pharmacotherapy available and correlate the effect of ageing on the effectiveness, leading to the recommendation of the best medication for elderly smokers. Method: A systematic searching strategy was performed in three different databases by using predetermined search strings. Results: Overall, this systematic review revealed that varenicline showed the greatest smoking cessation rate among the elderly, followed by bupropion and NRT. Conclusion: It is suggested that varenicline offered the best medical aid for smoking cessation in the elderly.

Assessment of Daytime and Nighttime Ground Level Ozone Pollution in Malaysian Urban Areas

@#Introduction: Ozone (O3 ) is a significant component of photochemical smog as a typical secondary which is formed via nitrogen oxide photochemical interactions with volatile organic compounds (VOCs). This research discerns the complex influence of meteorological parameters and air pollutants influencing O3 concentrations. Methods: Data were acquired from 1 January 2018 until 31 December 2020 that including ozone (O3 ), nitrogen oxide (NOx), nitric oxide (NO), sulphur dioxide (SO2 ), nitrogen dioxide (NO2 ), carbon monoxide (CO), particulate matter (PM10, PM2.5), wind speed, solar radiation, temperature, and relative humidity (RH). Data were analysed using descriptive statistics in terms of line graphs. Results: The results demonstrate that the O3 concentration peaked around 14:00 hours and dropped at night (20:00 hours) owing to the lack of sunshine and redox processes. Conclusion: In conclusion, ozone precursors played an important role in ozone formation and the findings of this research are valuable for policymakers and other interested parties

Dynamic Self-Determination of Self-Care and Positive Deviance Model for Stunting Prevention in Indonesia

ABSTRACT Objective: To describe the dynamic self-determination of self-care (DSDoSC) and positive deviance (PD) models in changing stunting prevention behavior. Material and Methods: This research is a quasi-experimental study with a sample of 90 mothers taken by purposive sampling. Thirty mothers were given the DSDoSC intervention, 30 were given the PD intervention, and another 30 were in the control group. This research was conducted in July - October 2019. The variables studied were feeding behavior, nurturing behavior, personal hygiene behavior, environmental cleanliness and air sanitation, and behavior seeking health services. To analyze the difference in mother behaviour before and after test, we used Paired t-test. Analysis of Variance (MANOVA) was used to analyze the difference of mother behaviour among groups. The level of significance was p<0.05. Results: The PWD group showed that eating behavior, parenting behavior, personal hygiene behavior, environmental hygiene and water sanitation, and behavior seeking health services had significant numbers. In the DSDoSC group, eating behavior, parenting behavior, environmental hygiene, water sanitation and health service-seeking behavior were significantly (p<0.05). The results of the Manova test showed that there was an effect of PD and DSDoSC on stunting prevention behavior. Conclusion: Self-dynamic for self-care model and the positive deviance model both can change a mother's behavior for the better in feeding, parenting, environmental hygiene, and water sanitation, seeking health services, but not changing behavior about personal hygiene behavior.

Incidence of Breakthrough Infections after COVID-19 Vaccination among the COVID-19 Vaccine Recipients at a Tertiary Care Hospital in Srinagar

COVID‑19 infections despite complete vaccination are called breakthrough infections. Breakthrough infections may decrease the vaccination confidence among people. This study was conducted soon after the Covishield vaccine was approved for use in J and K to find out the incidence of breakthrough infections among the recipients of the Covishield vaccine at SKIMS and to find out the associated factors. List of beneficiaries (between February 14, and May 15, 2021) was obtained from the records. Information was gathered telephonically. Incidence of breakthrough infections 6‑month postvaccination was determined. Among 919 participants, the incidence of breakthrough infections was 2.7% (25 cases). The medical profession was associated with a higher frequency of breakthrough infections. Most infections were mild to moderate (96%). One (4%) person required hospitalization. Thus, COVID‑19 infections can occur despite complete vaccination. Increased exposure places an individual at higher risk of breakthrough infections. Therefore, where exposure is high, COVID‑appropriate behavior should be followed despite being vaccinated.

Conhecimentos e práticas sobre telemedicina entre alergistas e imunologistas brasileiros / Telemedicine knowledge and practices among Brazilian allergists and immunologists

Introdução: O objetivo deste estudo foi avaliar as características das práticas de telemedicina (TM) entre médicos alergistas/ imunologistas (A/I) brasileiros e avaliar seu conhecimento sobre as recomendações regulatórias. Métodos: Uma pesquisa eletrônica autorreferida foi enviada por e-mail uma vez por semana entre agosto e outubro/2021 a 2.600 médicos A/I brasileiros. Resultados: 205 (7,9%) participantes preencheram os formulários. 143 (70,2%) médicos usaram TM em sua prática clínica, e 184 (89,9%) nunca o usaram antes da pandemia de COVID-19. Dentre os médicos, 192 (93,8%) utilizaram a TM para consultas de acompanhamento, 186 (91%) para verificação de exames complementares e 136 (66,7%) nas primeiras consultas. Cento e quarenta e três médicos A/I (70,2%) sentiram-se seguros em seu diagnóstico por meio da TM, e 7 (3,5%) responderam que não conseguiram encontrar um diagnóstico correto usando a TM. Os principais benefícios da TM relatados foram: maior acessibilidade, principalmente em áreas mais distantes 159 (77,6%), redução dos custos de deslocamento 158 (77,1%) e segurança quanto à transmissão do COVID-19 145 (71,2%). Por outro lado, algumas desvantagens da TM foram listadas pelos participantes: ausência de exame físico 183 (89,7%), relação médico-paciente fragilizada 59 (28,8%) e problemas de Internet 45 (22%). Em relação ao campo jurídico/ético, 105 (51,4%) dos especialistas aplicaram o termo de consentimento e 34 (16,7%) registraram a teleconsulta, ambas as etapas exigidas em uma consulta de TM, conforme recomendações regulatórias locais. Além disso, plataformas online inadequadas para TM, como aplicativos de mídia social e programas de reuniões online não específicos, foram relatadas como sendo usadas por 131 (64,1%) dos participantes. Oitenta (40%) não leram as declarações e recomendações oficiais que regulamentam a prática da TM no Brasil. Conclusões: Observouse um uso crescente de TM no Brasil, influenciado principalmente pela pandemia de COVID-19. Apesar de ser ferramenta útil na pandemia, com vantagens e desvantagens, há necessidade de conhecer as recomendações regulatórias.

Introduction: The aim of this study was to evaluate the characteristics of telemedicine (TM) practices among Brazilian allergists/immunologists (A/I) and to assess their knowledge of regulatory recommendations. Methods: A self-report electronic survey was sent by email once a week between August and October 2021 to 2,600 Brazilian A/I physicians. Results: A total of 205 (7.9%) participants completed the survey. TM was used in clinical practice by 143 (70.2%) physicians, and 184 (89.9%) had never used it before the COVID-19 pandemic. Among participants, 192 (93.8%) used TM for follow-up consultations, 186 (91%) for checking complementary exams, and 136 (66.7%) for first consultations. The number of A/I physicians (70.2%) that felt confident in their diagnosis using TM was 143, and 7 (3.5%) reported that they could not reach the correct diagnosis using TM. Participants reported that the main benefits of TM were greater accessibility, especially in more distant areas (159, 77.6%), reduced travel costs (158, 77.1%), and safety regarding the transmission of COVID-19 (145, 71.2%). Conversely, the lack of physical examination (183, 89.7%), poor doctor-patient relationship (59, 28.8%), and internet connection problems (45, 22%) were mentioned as disadvantages. Regarding legal/ethical aspects, 105 (51.4%) physicians reported applying a consent form and 34 (16.7%) reported making a record of the teleconsultation, both of which are required for TM consultations, according to local regulatory recommendations. The use of inappropriate online platforms for TM, such as social media applications and nonspecific online meeting programs, was reported by 131 (64.1%) participants. Eighty (40%) participants did not read the official statements and recommendations that regulate the practice of TM in Brazil. Conclusions: An increasing use of TM was observed in Brazil, mainly influenced by the COVID-19 pandemic. Despite being a useful tool in the pandemic, with advantages and disadvantages, physicians should have knowledge of regulatory recommendations.

Ameliorative effects of morel mushroom (Morchella esculenta) against Cadmium-induced reproductive toxicity in adult male rats / Efeitos benéficos do cogumelo morel (Morchella esculenta) contra a toxicidade reprodutiva induzida por cádmio em ratos machos adultos

Cadmium (Cd) is one of the major toxicants, which affects human health through occupational and environmental exposure. In the current study, we evaluated the protective effects of morel mushrooms against Cd-induced reproductive damages in rats. For this purpose, 30 male rats were divided into 6 groups (n=5/group), the first group served as the control group, second group was treated with an intraperitoneal (i.p) injection of 1 mg/kg/day of Cd. Third and fourth groups were co-treated with 1 mg/kg/day of Cd (i.p) and 10 and 20 mg/kg/day of morel mushroom extract (orally) respectively. The final 2 groups received oral gavage of 10 and 20 mg/kg/day of morel mushroom extract alone. After treatment for 17 days, the animals were euthanized, and testes and epididymis were dissected out. One testis and epididymis of each animal were processed for histology, while the other testis and epididymis were used for daily sperm production (DSP) and comet assay. Our results showed that Cd and morel mushrooms have no effect on animal weight, but Cd significantly decreases the DSP count and damages the heritable DNA which is reversed in co-treatment groups. Similarly, the histopathological results of testes and epididymis show that morel mushrooms control the damage to these tissues. Whereas the morel mushroom extract alone could enhance the production of testosterone. These results conclude that morel mushrooms not only control the damage done by Cd, but it could also be used as a protection mechanism for heritable DNA damage.

O cádmio (Cd) é um dos principais tóxicos, que afeta a saúde humana por meio da exposição ocupacional e ambiental. No presente estudo, avaliamos os efeitos protetores dos cogumelos morel contra os danos reprodutivos induzidos pelo Cd em ratos. Para tanto, 30 ratos machos foram divididos em 6 grupos (n = 5 / grupo); o primeiro grupo serviu de controle, o segundo grupo foi tratado com injeção intraperitoneal (i.p) de 1 mg / kg / dia de Cd. O terceiro e o quarto grupos foram cotratados com 1 mg / kg / dia de Cd (i.p) e 10 e 20 mg / kg / dia de extrato de cogumelo morel (por via oral), respectivamente. Os dois grupos finais receberam gavagem oral de 10 e 20 mg / kg / dia de extrato de cogumelo morel sozinho. Após o tratamento por 17 dias, os animais foram sacrificados e os testículos e o epidídimo foram dissecados. Um testículo e epidídimo de cada animal foram processados para histologia, enquanto o outro testículo e epidídimo foram usados para produção diária de esperma (DSP) e ensaio cometa. Nossos resultados mostraram que os cogumelos Cd e morel não têm efeito sobre o peso do animal, mas o Cd diminui significativamente a contagem de DSP e danifica o DNA hereditário, que é revertido em grupos de cotratamento. Da mesma forma, os resultados histopatológicos dos testículos e do epidídimo mostram que os cogumelos morel controlam os danos a esses tecidos. Considerando que o extrato de cogumelo morel sozinho pode aumentar a produção de testosterona. Esses resultados concluem que os cogumelos morel não apenas controlam os danos causados pelo Cd, mas também podem ser usados como um mecanismo de proteção para danos hereditários ao DNA.

Os dois grupos finais receberam gavagem oral de 10 e 20 mg / kg / dia de extrato de cogumelo morel sozinho. Após o tratamento por 17 dias, os animais foram sacrificados e os testículos e o epidídimo foram dissecados. Um testículo e epidídimo de cada animal foram processados para histologia, enquanto o outro testículo e epidídimo foram usados para produção diária de esperma (DSP) e ensaio cometa. Nossos resultados mostraram que os cogumelos Cd e morel não têm efeito sobre o peso do animal, mas o Cd diminui significativamente a contagem de DSP e danifica o DNA hereditário, que é revertido em grupos de cotratamento. Da mesma forma, os resultados histopatológicos dos testículos e do epidídimo mostram que os cogumelos morel controlam os danos a esses tecidos. Considerando que o extrato de cogumelo morel sozinho pode aumentar a produção de testosterona. Esses resultados concluem que os cogumelos morel não apenas controlam os danos causados pelo Cd, mas também podem ser usados como um mecanismo de proteção para danos hereditários ao DNA.

Ameliorative effects of morel mushroom (Morchella esculenta) against Cadmium-induced reproductive toxicity in adult male rats / Efeitos benéficos do cogumelo morel (Morchella esculenta) contra a toxicidade reprodutiva induzida por cádmio em ratos machos adultos

Cadmium (Cd) is one of the major toxicants, which affects human health through occupational and environmental exposure. In the current study, we evaluated the protective effects of morel mushrooms against Cd-induced reproductive damages in rats. For this purpose, 30 male rats were divided into 6 groups (n=5/group), the first group served as the control group, second group was treated with an intraperitoneal (i.p) injection of 1 mg/kg/day of Cd. Third and fourth groups were co-treated with 1 mg/kg/day of Cd (i.p) and 10 and 20 mg/kg/day of morel mushroom extract (orally) respectively. The final 2 groups received oral gavage of 10 and 20 mg/kg/day of morel mushroom extract alone. After treatment for 17 days, the animals were euthanized, and testes and epididymis were dissected out. One testis and epididymis of each animal were processed for histology, while the other testis and epididymis were used for daily sperm production (DSP) and comet assay. Our results showed that Cd and morel mushrooms have no effect on animal weight, but Cd significantly decreases the DSP count and damages the heritable DNA which is reversed in co-treatment groups. Similarly, the histopathological results of tests and epididymis show that morel mushrooms control the damage to these tissues. Whereas the morel mushroom extract alone could enhance the production of testosterone. These results conclude that morel mushrooms not only control the damage done by Cd, but it could also be used as a protection mechanism for heritable DNA damage.

Study on expression and significance of ferroptosis related genes in osimertinib acquired-resistant NSCLC cells based on transcriptomics / 中国药理学通报

Aim To explore the key genes of osimertinib aequired resistanee in non-small eell lung eaneer eells based on transcriptomics, anrl to analyze the significance in osimertinib resistant eells. Methods Hu man lung cancer HI975 cells and osimertinib resistant HI 975/OR cells were cultured in vitro. The effect of osimertinib and ferroptosis inducers on cell viability was measured by CCK-8 assay. The difference in gene expression was measured by transcriptomics. Hie expression levels of ferroptosis-related proteins were measured by Western blot. Results Osimertinib j eould inhibit the proliferation of HI975 eells and HI 975/OR eells in different concentrations, and HI975 cells were more sensitive. Transcriptomics analysis revealed remarkable differences in gene expression levels between HI975 and H1975/OR cells, among which the ferroptosis pathway was most significant. Western blot assay validated that different degrees of change existed in the expression levels of ferroptosis-re- lated proteins in HLF-1 , H1975 and H1975/OR eells. After the treatment of ferroptosis inducers RSL3 and Erastin, H1975/OR cells showed higher sensitivity, while little significance was observed on HI975 cells. Conclusions There were significant differences between HI975 lung cancer cells and osimertinib resist-ant H1975/OR cells on the gene expression levels, and the ferroptosis pathway plays an important role in acquired resistance to osimertinib.

Early Dental Implant Failure in Patient with Active Implant Periapical Lesions: Lesson Learnt from Two Case Reports

ABSTRACT@#Implant periapical lesion (IPL) is also known as retrograde peri-implantitis and as the name suggests, it involves inflammation surrounding the apical part of the dental implants. Previously, many studies have reported the event of IPL that further delays osseointegration, and some reported failure of implant placement due to this disease. In this article, we described two cases of early dental implant failure that was associated with active IPL and correlated the clinical and radiographical findings with the histopathological findings.

Facial Palsy with Tongue Ulcer: A Rare Initial Presentation of Granulomatosis with Polyangiitis

ABSTRACT@#Granulomatosis with polyangiitis (GPA) is a rare multisystem disease. Although GPA is rare, it commonly presents in a localised stage where its manifestation involves the upper or lower respiratory tract before progressing to a generalised stage. Therefore, most patients with GPA will visit an oral surgeon or an otolaryngologist to seek treatment. However, the diagnosis of GPA is often delayed as GPA is not frequently considered as a differential diagnosis in common oral and facial diseases. The lack of gold standard investigation for the diagnosis of GPA makes management of this case, a diagnostic conundrum. We herein report a patient who was diagnosed with bilateral acute otitis media and left mastoiditis complicated with facial nerve palsy, and later developed tongue ulceration one month after his initial presentation. The ear, facial and oral symptoms represent a diagnostic red herring to a full-blown generalised stage of GPA.

Effects of high-intensity interval training and strength training on levels of testosterone and physical activity among women with polycystic ovary syndrome

Objective@#Polycystic ovary syndrome is a diverse endocrine disorder characterized by hyperandrogenism and ovulatory dysfunction. Hyperandrogenism affects body morphology, resulting in excess weight (overweight or obesity). This study aimed to evaluate the efficacy of high-intensity interval training on serum testosterone levels, body fat percentage, and level of physical activity among women with polycystic ovary syndrome. @*Methods@#Fifty participants were enrolled in the study and randomly allocated into two groups. Group A performed highintensity interval training on alternate days per week (total of 12 weeks) and group B performed strength training on alternate days per week (total of 12 weeks). Baseline and 12th-week assessments included serum testosterone levels, body fat percentage using the skinfold method, and level of physical activity assessed using the International Physical Activity Questionnaire. @*Results@#After 12 weeks of intervention, both groups showed significant improvements in all the outcomes. However, group A (high intensity interval training) showed statistically significant results compared to group B (strength training) in lowering serum testosterone levels (P=0.049) and body fat percentage (P=0.001) and increasing physical activity levels (P=0.006). @*Conclusion@#After 12 weeks of exercise, both exercises benefited the participants; however, high-intensity interval training specifically was found to be a more effective exercise regimen than strength training in reducing serum testosterone levels and body fat percentage and enhancing levels of physical activity in women with polycystic ovary syndrome.

Spatial and Temporal Distributions Pattern of Dengue Fever Cases: A Ten Years Trends in Kuantan, Pahang

@#Introduction: Dengue fever (DF) is a prominent vector-borne disease spread by mosquitos of the Aedes genus (mainly Aedes aegypti, and even Aedes albopictus), a tropical regions vector. The purpose of this research was to establish the spatial and temporal distribution patterns of DF cases in the study area between 2010 and 2020. Methods: The correlation between the Kuantan sub-district and dengue haemorrhagic fever (DHF) incidence is examined in this study using spatial analysis. The correlation was calculated using spatial autocorrelation, Moran’s Index (Moran’s I) and Spatial Autocorrelation of Local Indicators (LISA). Moran’s index is a worldwide indicator used to determine whether or not disease transmission has geographical autocorrelation in disease transmission. Results: The results indicated that between 2011 and 2020, the monthly Moran’s I of dengue transmission in Kuantan was estimated to range between -0.685 and 0.338. The lowest reading of Moran’s index was -0.685 in May 2015, whereas the highest reading was 0.338 in May 2019. This reflects the strong spatial autocorrelation of dengue transmission in Kuantan over the last decade. The LISA analysis revealed significant spatial autocorrelations on DF cases in Kuantan for three (3) out of six (6) sub-districts (50%) with a significance level of 2%. This suggests that there are spatial autocorrelations in Kuala Kuantan, Beserah and Penor sub-district that influence the distribution of DHF transmission. Conclusion: The results reveal that the spatial autocorrelation analysis method can be a tool for relevant researchers to understand the pattern of DF transmission study and establish the direction for further study.

Recurrent Retrobulbar Optic Neuritis in Seronegative Rheumatoid Arthritis

@#Rheumatoid arthritis (RA) is a multisystemic autoimmune disease which can be associated with visual threatening ocular manifestations. Common ocular associations with RA include necrotising scleritis and peripheral ulcerative keratitis (PUK). Optic nerve involvement otherwise is uncommon, especially as a presenting feature of RA. We report a rare case of recurrent bilateral retrobulbar optic neuritis (ON) with progressive visual deterioration as an early manifestation of seronegative RA. This case posed diagnostic and management challenges due to its unusual presentation and initially inconclusive investigations. The patient was diagnosed with seronegative RA three years after the first eye presentation. Her RA disease activity score (DAS-28) improved after treatment with a disease-modifying anti-rheumatic drugs (DMARDs), and her ON attacks have been controlled since then. However, her visual acuity, visual field and colour vision remained poor after multiple ON attacks. Multidisciplinary care is key to managing such a patient’s condition and its potential disease complications.
