A Compact Bandpass Microstrip Filter for Wireless Communication Applications

A design of Compact Bandpass Microstrip Filter is proposed for wireless communication applications like Bluetooth, Wi-Fi, and 5G. Filter is constructed using parallel-coupled Microstrip lines to form 5th order filter of an inverted C structure. Ground slotted technique is used to enhance the bandwidth with dielectric constant of 9.9. The designed filter is simulated at a center frequency of 5.87GHz and bandwidth of 1.9GHz with an insertion loss of -0.5dB, return loss of greater than 12dB. The proposed filter has a compact size, good increased bandwidth and cost-effective. These results are verified with the theoretically designed values and good agreements are recorded. Hence the proposed compact filter will provide a platform for designing and development of compact filters for the microwave regime

Diphyllobothriasis in a nine-year-old child in India: a case report

<p>Abstract</p> <p>Introduction</p> <p>The <it>Diphyllobothrium </it>genus belongs to the <it>Diphyllobothridea </it>order of tapeworms. <it>Diphyllobothrium </it>spp., which is commonly known as fish tapeworm, is generally transmitted in humans, but also in other species, such as bears, dogs, cats, foxes, and other terrestrial carnivores. Although worldwide in distribution, the original heartland of <it>Diphyllobothrium </it>spp. spreads across Scandinavia, northern Russia, and western Serbia. We report a rare case that occurred in India.</p> <p>Case presentation</p> <p>A nine-year-old south Indian girl was brought to the casualty at the Prathima Institute of Medical Sciences with complaints of vomiting and loose stools that had started three days earlier. The vomit did not have a foul smell and contained no blood or mucus, but it did contain undigested food particles. The patient described a history of recurrent abdominal pain. She was a non-vegetarian and said she had a history of eating fish.</p> <p>Conclusion</p> <p>The incidence of <it>Diphyllobothrium </it>spp. infection is infrequent in India. Since this is only the fourth reported case in India, and since the previously reported cases also involved observed pediatric patients, we emphasize the need for clinical microbiologists and pediatricians to suspect fish tapeworm infection and recommend epidemiological study of <it>Diphyllobothrium </it>spp. infection.</p

Midwifery education in Pacific Island countries: A discussion paper.

BACKGROUND: The aim for 95% maternal health care coverage and zero-unmet need for family planning in Pacific Island countries by 2030 could be achieved by strengthening the midwifery workforce. To enable health services to provide accessible, locally acceptable, and high-quality care, the midwifery workforce must be regulated and educated to global standards and supported to practice in enabling environments. In 2019, around 64,000 live births occurred in Pacific Island countries, yet information regarding the state the midwifery workforce and midwifery education is limited. AIM: Using data from recent reports and country case studies, this paper provides an overview of the current midwifery education situation in Pacific Island countries and discusses strategic directions for strengthening quality midwifery education and therefore quality midwifery care provision in Pacific Island countries. DISCUSSION: Six Pacific Island countries have midwifery curricula, all post-nursing programs, although few offer midwifery education programs on a regular annual basis. Current programs do not meet ICM Global Standards for Midwifery Education. Critical areas for strengthening include making underpinning philosophical frameworks, the vision for midwifery education, and program intended learning outcomes explicit in curricula documents and ensuring integration of these in program implementation. Fortunately, five of six midwifery education programs are under processes of renewal and strengthening against global, regional, and national standards. CONCLUSION: Strengthening the midwifery workforce in the Pacific to meet maternal and newborn health targets can be achieved through supporting the existing midwifery education programs to meet global standards. Strengthened midwifery education programs in Pacific Island countries offer an opportunity to meet each country's maternal and newborn health targets

Can Global Variation of Nasopharynx Cancer Be Retrieved from the Combined Analyses of IARC Cancer Information (CIN) Databases?

BACKGROUND: The international nasopharynx cancer (NPC) burdens are masked due to the lack of integrated studies that examine epidemiological data based on up-to-date international disease databases such as the Cancer Information (CIN) databases provided by the International Agency for Research on Cancer (IARC). METHODS: By analyzing the most recently updated NPC epidemiological data available from IARC, we tried to retrieve the worldwide NPC burden and patterns from combined analysis with GLOBOCAN2008 and the Cancer Incidence in Five Continents (CI5) databases. We provide age-standardized rates (ASR) for NPC mortality in 20 highest cancer registries from GLOBOCAN2008 and the World Health Organization (WHO) mortality databases, respectively. However, NPC incidence data can not be retrieved since it is not individually listed in CI5 database. The trend of NPC mortality was investigated with Joinpoint analysis in the selected countries/regions with high ASR. RESULTS: GLOBOCAN 2008 revealed that the highest NPC incidence rates in 2008 were in registries from South-Eastern Asia, Micronesia and Southern Africa with Malaysia, Indonesia and Singapore ranking the top 3. WHO mortality database analysis revealed that China Hong Kong, Singapore and Malta ranks the top 3 regions with the highest 5-year mortality rates. CONCLUSIONS: NPC mortality rate is about 2-3 times higher in male than that in female, and shows decrease tendency in those selected countries/regions during the analyzed periods. However, the integrated analyses of the current IARC CIN databases may not be suitable to retrieve epidemiological data of NPC. Much effort is required to improve the local cancer entry and regional death-reporting systems so as to aid similar studies

Cytokine and Protein Markers of Leprosy Reactions in Skin and Nerves: Baseline Results for the North Indian INFIR Cohort

Leprosy affects skin and peripheral nerves. Although we have effective antibiotics to treat the mycobacterial infection, a key part of the disease process is the accompanying inflammation. This can worsen after starting antibacterial treatment with episodes of immune mediated inflammation, so called ‘reactions’. These reactions are associated with worsening of the nerve damage. We recruited a cohort of 303 newly diagnosed leprosy patients in North India with the aim of understanding and defining the pathological processes better. We took skin and nerve biopsies from patients and examined them to define which molecules and mediators of inflammation were present. We found high levels of the cytokines Tumour Necrosis Factor alpha, Transforming Growth Factor beta and inducible Nitric Oxide Synthase in biopsies from patients with reactions. We also found high levels of bacteria and inflammation in the nerves. These experiments tell us that we need to determine which other molecules are present and to explore ways of switching off the production of these pro-inflammatory molecules
