Repositioning Cooperative Poultry Farming as a Vocation for the Unemployed Youths
Authors: Thulisile Ndashe Pinky Flavia , Lavendal Carol , Olumuyiwa Omotosho Ademola
Published: January 2024

The widespread impact of the Coronavirus pandemic has led to substantial job losses, prompting increased pressure on policymakers, scholars, and non-governmental organizations to generate sustainable employment opportunities for young individuals, particularly within economically disadvantaged communities. This investigation focuses on the feasibility of integrating unemployed youth into established commercial broiler value chains as a means to address the employment gap resulting from the pandemic. Its objective is to raise awareness among governments, institutions, and stakeholders regarding the hurdles faced by young people aspiring to engage in chicken production. To assess the current status of small-scale poultry farming in the studied region, interviews were conducted with small-scale poultry producers in Umhlathuze Municipality, KwaZulu-Natal, South Africa, along with experts from Owen Sithole College of Agriculture. Insights gathered from participants indicate various obstacles to poultry production in the area, such as insufficient digital, limited space, skill-shortage, restricted market access, low profitability, and instances of theft. Consequently, a proposed solution, the 'Collective Farming Model,' is advocated. Moreover, the authors contend that the efficacy of this model hinges significantly on its apprenticeship-based learning system, validated through successful implementation in a prototype initiative.

Severe cutaneous vasculitis as a symptom of right-sided infectious endocarditis in a patient with intravenous using of methadone: a clinical case
Authors: Todorova Y. M. , Gospodinov K. D. , Lukanov M. E. , Tisheva S. T.
Published: January 2024

A bacterial infection of the heart’s endocardial surface causes infectious endocarditis (IE). The heart valves or an intracardiac devices are most affected. In most cases of right-sided endocarditis, the tricuspid valve is involved. Using drugs like cocaine, heroin, or any number of others can cause this disorder. Infective endocarditis can develop if methadone is not administered in accordance with the Methadone program, despite the cessation of drug use. In drug users, Staphylococcus aureus is the most common cause of right-sided infective endocarditis with pulmonary embolism and persistent bacteraemia. Cutaneous vasculitis, particularly leukocytoclastic vasculitis, is a rare manifestation of IE.

Published: January 2024

The current study analyses the activity on cardiac pacing in Bulgaria in 2022 based on data derived from a national registry of patients with cardiac implantable electronic devices (CIEDs). Materials and methods. Data from the national registry BG-Pace for 2022 was studied retrospectively. Demographic data, procedure and device type, pacing mode, etiology, symptoms, preimplantation ECG, number of implantations, and centre and operator volumes were analyzed. Results: Four thousand seven hundred seventy devices were implanted by 45 operators in 30 centers. Median age was 76 (IQR 69-82, 14-98) years, and male patients were 2843 (59,6%). The most significant number of implantations were carried out in the age group 70-79 years. The most commonly implanted CIEDs were antibradycardia devices - 578,8/million. Of them, conduction system pacing was used in 111 (2.3%). Implanted cardioverter-defibrillators demonstrated a growth compared to previous periods and reached 31.9/million. Cardiac resynchronization defibrillators implantations also shown a growth to 15.9/million. A considerable increase was found with implantable loop-recorders, which reached 8.8/million. Number of implantations per center was 115.5 (IQR 53-261.,3, 3-546), and 76,5 (IQR 36,8-154,8, 3-364) devices per operator. Dual chamber devices were most commonly implanted with a share of 83.1% in AVB I and II degrees, 72.5% in complete AVB, 82.6% in intraventricular conduction disturbances, and in 66.8% in patients with sick sinus syndrome. Pacing modes allowing for atrial sensing were most frequently implanted – 62.4% of all implantations for conduction disturbances. There was a significant increase in the use of VVI mode with increasing age (P<0.001). Conclusion: The national registry BG-Pace includes systematic clinical, demographical, and procedural data for CIED implantations in Bulgaria. There is a growth in the implantation rates compared to previous periods, but they remain lower than the average number for Europe.

Overview of Vaginal Ulcerative Disease
Authors: Dhar Cherie Priya , Feuerstein Jessica L. , Salas-Humara Caroline
Published: January 2024

Genital ulcers may be located on the vagina, penis, and anorectal or perineal areas and may be infectious or noninfectious. Vaginal ulcers affect patients of all ages and are commonly due to sexually transmitted infections, such as herpes simplex virus, the most common cause of genital ulcers in the United States. Non–sexually transmitted infections, such as Epstein-Barr virus, and other noninfectious causes, such as trauma, medications, and autoimmune disease, rarely can present with genital ulcers. Appropriate history, examination findings, and targeted testing must be used to correctly diagnose and treat vaginal ulcers.

Strategies for Creating Multidisciplinary Community Care Teams to Address Barriers to Providing Family Based Treatment of Eating Disorders
Authors: Horn Kelly , Morgan Renée N. , Franceschi Courtney L.
Published: January 2024

Eating disorders, especially anorexia nervosa, are complex and devastating illnesses. Although eating disorders have a high mortality rate and are relatively common, there are many barriers for those seeking treatment. Provider training and education, weight bias among health care providers, geographical and language barriers, and a lack of options because of insurance restrictions prevent many families from receiving appropriate care, especially in smaller or rural communities. In those areas, providers are left to piece together treatment using a small number of other providers from different disciplines who have a willingness to work with this population. Outpatient family based treatment is an evidenced-based treatment of anorexia nervosa and relies on a multidisciplinary approach to care. Community-based care teams can be an effective way to treat those with eating disorders seeking family based treatment. There are several strategies for building collaborative teams that can provide comprehensive and accessible care to those with few options.

THE EDWIN FOX: THE SECRET SHIP, YOU HAVE NEVER HEARD OF, AT THE OTHER END OF THE WORLD, PRESERVED AGAINST ALL ODDS BY A HANDFUL OF ENTHUSIASTIC TOWN LOCALS...
Authors: McLeod K
Published: January 2024

The Edwin Fox ship, built in India in 1853, (Figure1) has many stories to tell, from its adventures on the high seas to how it came to rest in a small, amazing little town at the other end of the world from where it began its life. The Edwin Fox is not well known, yet its story is not only important to Picton, Marlborough, a Provence with a rich maritime heritage from the early Polynesian explorers to Captain Cook in 1770, [6] but to Aotearoa, (New Zealand) as a country, and indeedthe world, there is much to be learnt from the ship.
The Edwin Fox is unlike any other historic ship due to the way the preservation of the ship was undertaken. It is one of the few historic ships in the world that people have been able to physically interact with.
In this paper I hope to inform the audience of the history of the Edwin Fox with reference to the various RINA conference topics.
I will showcase the importance and tenacity of volunteers, whom with passion and very little else, achieved remarkable outcomes while also highlighting some of the
negative aspects.
I will also highlight our present plight today with regards the ship preservation project and the need for expertise, particularly in the field of engineering given the complication of the ship being docked in an Earthquake prone area, making this a truly unique opportunity.
ROBERT SEPPINGS, A VISIONARY STRUCTURALIST
Authors: Corradi M , Tacchella C
Published: January 2024

The prolegomena of graphical statics in shipbuilding are uncertain and can only be deduced from a thorough reading of some authors’ writings. Among them, Robert Seppings excelled for his innovative ideas especially concerning the increase of resistance of vessels, in particular with respect to the hogging phenomenon, by using
reticular structures. The intent of this article is to tell a short story of the innovations and improvements that have taken place in wooden shipbuilding starting from the ideas of Seppings, regarding naval design engineering as well as the architecture of shipyard buildings. The importance of these ideas is proved by the fact that once entered
the shipyard they were in use until the second half of the 19th century when they were finally replaced by the use of iron and steel. For these reasons, Seppings’ ideas and drawings are a precious part of the maritime heritage which deserves to be remembered.

SS GREAT BRITAIN: VOYAGE TO CARBON NEUTRAL
Authors: Grahamslaw N
Published: January 2024

Brunel’s SS Great Britain, the first iron ship, is conserved and displayed in the historic dry dock where she was built. The most vulnerable parts of the original wrought iron hull are preserved by keeping the surrounding air at 20% relative humidity to prevent corrosion. A glass “sea” at waterline level creates a seal, and bespoke desiccant dehumidifiers desiccate the environment inside and underneath the ship. This conservation method relies on natural gas for drying the air, and electricity for circulating it.
A CASE STUDY OF HISTORIC SHIPS IN CANADA: THE STEAM TUG MASTER
Authors: Allan R G
Published: January 2024

The paper describes the lack of coherent or consistent policies within Canada which would enable the recognition and ultimately the preservation of worthy vessels of historic importance. Current designations of vessels as “National Historic Sites” are very few, and the responsible departments within government at all levels lack a clear set of criteria for such designation. The impact of that state of affairs on the
attempts at preservation and restoration of the century-old, historic steam tug Master in British Columbia is described.
Les Arméniens d’Égypte dans la première moitié du xixe siècle : le secours aux plus démunis au défi de la migration
Authors: Kazazian Anne
Published: January 2024

Au début du xixe siècle, des Arméniens viennent s’installer en Égypte à partir des terres centrales de l’empire ottoman, renouvelant profondément une petite communauté présente depuis longtemps en Égypte mais très peu structurée. Si quelques-uns des nouveaux venus, très proches de Muhammad Ali, gouverneur puis vice-roi d’Égypte, affichent une réussite remarquable, ce n’est pas le cas de tous. L’aide aux plus démunis est un des éléments qui incombait à la communauté dans le système des millets. Elle participe à la fabrique de la nouvelle communauté tant par rapport aux autres communautés en Égypte qu’aux Arméniens de l’empire ottoman.
Welfare after Empire: Italy, Egypt, and the politics of assistance after 1945
Authors: Viscomi Joseph J.
Published: January 2024

How could a state’s distanced approach to the welfare of its national subjects shape experiences at the end of empire? In this article, I consider this question by looking at the relationship between the Italian state and the departure of Italians from Egypt after 1945. The article presents a sociopolitical history of how experiences and expectations of welfare have shaped relations between the state and its migrant subjects at the end of empire. I argue that the regional strategies of the postwar Italian state turned away from institutional support of Italian residents in Egypt as a means of positioning itself closer to Nasser’s government after 1954 and, in doing so, marginalised the interests of migrant Italians even while it relied on interwar narratives about their importance for Mediterranean political kinships. The article begins by using oral history to understand how the memories of repatriated Italians from Egypt framed the historical context of experiences and expectations of welfare support in relation to the state. It then looks back to the political conjuncture of the early 1950s and its reverberations among Italians in Egypt seeking to re‑establish their lives after the Second World War, the collapse of fascist imperialism, and decolonisation. It examines how, at the very moment the two new republics moved closer together one another, Italian residents in Egypt were kept at a strategic distance by the Italian state and its diplomatic actors in Egypt. With the so‑called unmixing of the colonial sea, then, it looks at how Italians sought – and failed to acquire – aid and assistance from the Italian state when departing from Egypt and how this contoured the perspectives of Italian repatriates.

Published: January 2024

Direct chill (DC) casting has been considered as one of the promising casting methods that can be used to produce aluminum alloys billet. The process is conducted by pouring aluminum metal into a water-cooled mold. The billet shell begins to form when molten aluminum contact directly with the mold (this is also known as primary cooling). Afterward, the starting block is pulled downwards at a specified casting speed to achieve desired aluminum billet. The start-up phase during the DC casting process is considered a crucial step since it may determine the formation of defects in the casting products. This research aims to investigate the casting defects on the aluminum alloy that were formed during the start-up process of DC casting. The results show that the billet failed to form following the downward movement of starting block. Meanwhile, the billet tended to stick to the mold wall due to several factors, such as too low a pouring temperature, a less-round mold shape, the poor quality of the hot top and graphite ring, and the water that entered the mold during the casting process. It also noted several markers of the casting defects that occurred during the DC casting process such as liquation or bleeding, cold folding, billet stuck in the mold, butt structure, and rough billet surface.

Published: January 2024

It is well-known that silica sand is a special type of quartz sand that is suitable for glass fabrication due to its high silica content and low content of iron oxide. In this work, chemical analysis has been carried out on a sand sample from the Nong Phok site, Roi Et province, northeastern Thailand. The geological resources show that this site possesses a surface-to-near surface sand deposit. The grain of fine white sand consists of clear crystals. The grain shape is mainly angular-to-round. Chemical analysis shows that the sand contains more than 99 wt% silica and small amounts of Al, Ca, Ti, and Zr which is in agreement with international standards for glass production. The sand has been used as raw material for the fabrication of soda-lime, lead crystal, and lead-free high refractive index glasses. The colorless and various colored glass products have been satisfactorily used in domestic art and glass manufacturers which promotes local employment and economics.

Published: January 2024

Lithium-ion batteries like LiFePO4 become a new choice for electrical energy sources in the world and can be used on electric vehicles. Battery packs monitoring by Battery Management System in electric vehicles require accurate monitoring. The inaccuracy of monitoring such property can lead to low safety, low efficiency and battery’s life reduction. Estimating state of charge (SoC) to prevent battery damage from overcharging and over discharging. Some of the methods used to estimate SoC such as Coulomb Counting have errors during the charge and discharge process. This research proposes a counting method for measuring SoC with the artificial neural networks (ANN) to provide more precise estimation. Feed Forward Neural Network (FFNN) is an ANN model that can give an accurate estimation of SoC by learning data of the charge-discharge process performed on sample batteries. The sample batteries are tested with a battery analyzer to get its charging-discharging data consisting of variables such as voltage, current, capacity, and time with C-Rate variations. These variables data are then learned by the modeled FFNN to predict SoC value. The FFNN model consisted of 16 neurons in the first layer, 8 neurons in the second layer, and 4 neurons in the third layer. The predicted SoC value from FFNN has a similar value with its real SoC value. The relationship between SoC and battery voltage is plotted in a curve and shows an identical characteristic with how the SoC-Voltage curve of a battery should be and have a low mae value. This FFNN model can be applied further such as in electric vehicles to maintain its safety and for longer use.

Authors: Fauziah Nisa Aina , Kurniawan Teguh , Irawan Anton
Published: January 2024

The existence of oxygen is needed in various fields such as health, industry, aerospace, and energy. Pressure swing adsorption method using zeolite A and X is commonly used in the oxygen separation process. Zeolite LiX is widely used especially in oxygen purification systems from air for medical needs until the purity reach >90%. In the present work the simulation studies of oxygen separation from air using zeolite LiX were investigated by pressure swing adsorption method. This simulation uses 2 beds/4 steps Skarstrom cycle which generally consists of bed pressurization, adsorption, depressurization and desorption. Several variables were studied such as the effect of pressure, cycle time, and temperature to determine the level of product purity. The simulation shows that the increase in oxygen concentration is caused by an increase in operating pressure and total cycle time to obtain maximum results. Meanwhile, large pressures can reduce the efficiency of the adsorbent. The maximum oxygen concentration that can be obtained up to 99%. However, the temperature variation has no significant change. In general, pressure plays the most significant role in oxygen purification.
An Assessment of the Environmental Sensitivity of the Coastal Zone of Negombo, Sri Lanka
Authors: Botheju W. Ishini Udha , Herath H. M. Malani
Published: January 2024

The coastal area of Sri Lanka provides various ecosystem services amidst various challenges. For instance, coastal erosion is an ongoing problem caused by human activities. Sensitivity assessment one of the measures which helps planning coastal areas to ensure better urban development and environmental protection. This study developed a framework for the assessment of the environmental sensitivity of coastal zones. The framework primarily considered sensitive biological factors and external disturbances, demonstrated in the Negombo coastal zone. 16 indicators were selected, considering the area with AHP technique, and the weighted summation method was used to assess the sensitivity. The assessment enables the study region of an area of around 38km2 to be divided into zones of very high, high, moderate, low, and very low sensitivity. The maps generated out of this assessment can be used to identify areas that require prioritized management. The very highly sensitive areas need priority in management as the sensitive biological aspects and external disturbances were both high in them. In the other areas, either the external disturbance or the sensitive biological aspects are high. Having identified the level of sensitivity, appropriate actions could be taken to either maintain the status of the biological aspect or to regulate the external disturbance in that area. Some areas were identified as very low to low sensitivity indicating their potential for development. This study provides a model framework to assess the sensitivity of coastal zones as a measure towards planning for sustainable developments in them.
Assuring Sustainable Construction at Project Inception Stage: A Project Feasibility Evaluation Criteria
Authors: Senanayake Gayani , Hadiwattage Chandanie , Perera Kanchana
Published: January 2024

Sustainable construction (SC) practices are crucial for minimising environmental impacts and enabling the long-term viability of construction projects. However, sustainability considerations are often lacking during early project stages in developing countries like Sri Lanka. This research aims to mandate sustainability assessment at the critical project feasibility stage by proposing sustainable feasibility criteria. A qualitative Delphi study gathered experts' insights on incorporating sustainability factors into feasibility evaluations. The findings reveal 68 minimum sustainability requirements spanning economic, social, and environmental dimensions which should be assessed during feasibility studies. Further analysis identified 35 non-legalised sustainability criteria along with measurable factors and relevant Sri Lankan authorities to mandate their evaluation. By requiring consideration of these criteria, project owners and developers can be compelled to integrate sustainability principles during initial decision-making. This research provides a vital first step towards mainstreaming sustainability practices through mandated feasibility assessments. The proposed sustainable feasibility evaluation framework with specific criteria ensures that all projects account for sustainability impacts before approval, driving improved triple-bottom-line performance.

Aims: we estimated the probability of a positive result for the most common bacterial causal agents of diarrhea, such as Campylobacter spp., Salmonella spp., Shigella/Enteroinvasive Escherichia coli, Yersinia enterocolitica or Shiga toxin-producing Escherichia coli by a stool multiplex Polymerase Chain Reaction (PCR) assay in a pediatric population evaluated at the Pediatric and Pediatric Emergency Unit, Children Hospital of the Azienda Ospedaliera SS. Antonio e Biagio e Cesare Arrigo, Alessandria, Italy, during the period April 2022 - July 2023. Methods: we analyzed the clinical data collected by the Pediatrician on the stool sample request form along with complete blood count and C-Reactive Protein (CRP). Results: in our case series, the presence of blood/mucus in stool along with an increased value of CRP are independently associated with a positive result diagnosed by molecular method for bacterial diarrhea caused by the aforementioned pathogens. Conclusions: the results proposed in this paper can be of help in hospital settings without the availability of a stool multiplex PCR assay to estimate the probability of bacterial diarrhea in a pediatric patient.
Common hydrology features (CHyF) logical model
Authors: Sondheim M , Hodgson C
Published: January 2024

The Open Geospatial Consortium has defined "OGC WaterML 2: Part 3 - Surface Hydrology Features (HY_Features) - Conceptual Model", but not any particular implementation of it. The Common Hydrology Features (CHyF) model extends HY_Features and makes some minor
changes to it required for implementation and the delivery of high performance services. HY_Features discusses catchment coverage and topological relations. In CHyF these are key ideas, as is the notion that hydrologically defined network components form elements of a mathematical graph, allowing
for very fast network traversal. HY_Features defines catchments and catchment networks, as well as rivers, channels, flowpaths and hydrographic networks. The CHyF logical model specifies a profile and some extensions to HY_Features, as required to implement topological and graph relations. This
starts with the definition of elementary catchments and elementary flowpaths, which are treated as fundamental elements. They are tightly specified terms corresponding to basic catchments and flowpaths in HY_Features and the basic components in the standard reach-catchment model (Maidment and Clark,
2016). If they are subdivided, the result is simply more elementary catchments and elementary flowpaths. Consequently, they are the building blocks used to form complementary coverages as well as a graph structure referred to as a hygraph. Building the hygraph necessitates that connections between
features be manifest through their geometry. Divergences and distributaries are supported in CHyF, as the hygraph need not be hierarchical. Nevertheless, CHyF does recognize hierarchical drainage basins and the value in identifying them explicitly (Blodgett, et al, 2021). Different kinds of
elementary catchments and elementary flowpaths are defined in CHyF. Of note is that polygonal waterbody features, or portions of such features, are treated as elementary catchments in their own right. In addition to these water catchments, several kinds of land-based elementary catchments are
recognized. These model constructs are compatible with the higher level conceptual model in HY_Features, although they differ in detail from other popular implementation models. With the approach taken it becomes practical to handle very large lakes and rivers, as well as coastal ocean zones. CHyF
also includes wetlands, glaciers and snowfields as kinds of hydro features; these features help complete the concept of a catchment coverage as put forward by HY_Features.

20P/13). The global rise in lithium demand has motivated the Geological Survey of Canada's (GSC) recent investigations of the Brazil Lake pegmatites to study surficial geochemistry methods that can be used to explore for lithium and associated critical minerals (i.e., Cs, Ta, Be, In, Sn, W). These
types of deposits are important sources of lithium, tin, and rubidium and the primary source of tantalum. This research at Brazil Lake is being undertaken as part of the GSC's Targeted Geoscience Initiative Program and has been carried out in partnership with the Nova Scotia Department of Natural
Resources and Renewables (NSDNRR). The goals of the research are to increase exploration success in regions covered by glacial sediments by documenting how critical minerals and associated elements are glacially dispersed in till from pegmatites at the Brazil Lake property. Newly available LiDAR
data assisted in deciphering ice flow trajectories, which in turn, allowed for targeted till sampling. A total of 184 till samples were collected for till geochemistry in 2020, 2021 and 2022 and the data reported here include widely spaced regional samples collected across southwest Nova Scotia,
proximal samples collected up-ice, overlying, and down-ice of the Brazil Lake pegmatites. The widely spaced till samples provide the regional context for the interpretation of the case study samples and assess the potential for additional pegmatites buried by extensive till cover. Data reported in
this Open File include sample descriptions, location, site photos, and geochemical analyses of the coarse sand (1.0 - 2.0 mm) and silt + clay (<0.063 mm) fractions. For the 2020 samples only, the <0.002 mm (clay) fraction was also analyzed. Analyses over the 3 years
(2020-2021-2022) include various combinations of different digestions or fusions to test and compare their efficacy for the various pathfinder elements for LCT pegmatites: aqua regia (partial) digestion, 2) Na peroxide fusion (total), 3) 4-acid (near total) digestion, 4) Li-meta/tetraborate fusion,
5) loss on ignition, and 6) portable X-ray fluorescence (XRF).

Published: January 2024

Background:

The World Health Organization introduced the entities of sessile serrated adenoma and traditional serrated adenoma, and hyperplastic polyps (HPs) under the serrated lesions category in 2010. Indian studies on demographic, clinical, and histopathological characteristics of colorectal polyps, especially on serrated lesions, are limited. Our study aimed to study the morphology of the colorectal polyps and estimate the percentage of serrated lesions in the polyps studied.

Methodology:

A cross-sectional hospital-based study was conducted on colorectal polyps received for routine histopathological examination from July 2013 to August 2015. The polyps were classified according to the WHO 2010 colon and rectum tumors classification. Data were compiled and analyzed using IBM SPSS statistics version 20.0. The interpretation was done in frequencies and percentages.

Results:

We studied a total of 200 colorectal polyps. The polyps were mostly seen in the descending colon (41%). Histologically, the majority of the colorectal polyps were adenomatous in nature (59%). The serrated lesions accounted for 29% of all colorectal polyps. The polyps were mostly seen in patients who were more than 40 years old.

Conclusion:

Adenomas were the most prevalent type of colorectal polyps, seen more in males, at a higher age, and distally located. Serrated lesions predominantly included HPs, mostly <1 cm in size.

Photodermatoses represent a broad spectrum of skin diseases caused because of exposure to ultraviolet radiation. It is categorized mainly as idiopathic photosensitive disorders, drug or chemical induced photosensitivity reactions, DNA repair-deficiency photodermatoses and photoaggravated dermatoses. Despite being under the photodermatoses umbrella, the pathophysiology of each type of photodermatoses varies. We reported 4 cases of photodermatoses including azathioprine induced pellagra, adult onset actinic prurigo, and photoallergic contact dermatitis due to NSAIDs and cutting fluids. Photoprotection with the usage of photoprotective clothing, broad-spectrum sunscreen application and avoidance of photosensitizing drugs and chemicals are crucial.

Authors: Jawade Sugat , Saoji Vikrant , Madke Bhushan , Singh Adarshlata
Published: January 2024

Background:

Vitiligo is a common acquired depigmentory skin disorder supposed to be of autoimmune aetiology. Different immunosuppressants have been tried with varying success. Azathioprine has been less studied in vitiligo.

Aims and Objectives:

To study the efficacy of oral azathioprine and compare with systemic steroid in the treatment of vitiligo.

Materials and Methods:

It was an interventional study with multi-armed (three), parallel group, an open-label, randomized controlled trial with allocation ratio of 1:1:1. Patients of vitiligo aged between 18 and 60 years having more than 5% body surface involvement were included in the study. Patients were divided into three groups. Group A—patients received oral azathioprine 50 mg OD daily, group B—patients received combination of oral azathioprine 50 mg OD and PUVASOL and group C—patients received combination of betamethasone oral mini pulse (OMP) and PUVASOL. All the groups were treated for 1 year. Repigmentation was evaluated by vitiligo area severity index (VASI), and stabilization was evaluated by vitiligo disease activity (VIDA).

Results:

Group A, group B and group C showed 24.24%, 53.24% and 47.28% improvement in VASI score, respectively, at the end of 1 year. Group B and group C showed statistically significant superior repigmentation as compared to azathioprine monotherapy. Though azathioprine and betamethasone showed equivalent efficacy, azathioprine has a better safety profile. Side effects were minimal in azathioprine groups, whereas 50% patients developed various side effects in group C.

Conclusion:

Azathioprine is safe and effective option in the treatment of vitiligo.
Real-World Indian Experience of Switchover to Bilastine 40 mg/day in CSU Patient Refractory to Other Antihistamines at Double Dose
Authors: De Abhishek , Shah Bela , Banodkar Pravin D. , Dhoot Dhiraj , Chitnis Kruttika , Barkate Hanmant
Published: January 2024

Background:

Although second-generation antihistamines (SGAHs) are recommended as first-line drugs in chronic spontaneous urticaria (CSU), symptom relief has been reported in <50% of patients at licensed doses and up to fourfold dosing is recommended for these patients. Bilastine (SGAH), at licensed doses and higher doses, is efficacious in CSU. However, large-scale real-world data is scarce.

Objectives:

To report the real-world evidence of the safety and effectiveness of bilastine at a double dose (40-mg per day) in CSU management.

Materials and Methods:

In this retrospective questionnaire-based study carried out from February 2022 to July 2022, a pre-validated questionnaire was used to gather data on patients with CSU in dermatology practice from 62 centres across India. Adult patients of either gender diagnosed with CSU and switched over to bilastine 40 mg/day due to a non-satisfactory response (UCT score <12) to other antihistamines at double dose were considered for analysis. Based on UCT scores, patients were classified as responders (UCT ≥12) and non-responders at follow-up assessment at 2 weeks as compared to baseline.

Results:

177 patients with a mean disease duration of 2.11 ± 1.48 years were included in the final analysis, with 53% females and 47% males. At the end of two weeks, 74/177 (42%) patients were classified as responders, and 103/177 (58%) were non-responders to Bilastine 40 mg/day. The mean change of UCT score from 5.0 ± 2.2 at baseline to 8.08 ± 5.41 (62% improvement) was significant (P < 0.001). Sedation was reported by ten patients without any discontinuation of treatment.

Conclusion:

Bilastine 40 mg/day was effective and well-tolerated in controlling CSU symptoms refractory to antihistamines at double doses.

New trends in diagnosis and management of gallbladder carcinoma

Published: January 2024

Gallbladder (GB) carcinoma, although relatively rare, is the most common biliary tree cholangiocarcinoma with aggressiveness and poor prognosis. It is closely associated with cholelithiasis and long-standing large (> 3 cm) gallstones in up to 90% of cases. The other main predisposing factors for GB carcinoma include molecular factors such as mutated genes, GB wall calcification (porcelain) or mainly mucosal microcalcifications, and GB polyps ≥ 1 cm in size. Diagnosis is made by ultrasound, computed tomography (CT), and, more precisely, magnetic resonance imaging (MRI). Preoperative staging is of great importance in decision-making regarding therapeutic management. Preoperative staging is based on MRI findings, the leading technique for liver metastasis imaging, enhanced three-phase CT angiography, or magnetic resonance angiography for major vessel assessment. It is also necessary to use positron emission tomography (PET)-CT or 18F-FDG PET-MRI to more accurately detect metastases and any other occult deposits with active metabolic uptake. Staging laparoscopy may detect dissemination not otherwise found in 20%-28.6% of cases. Multimodality treatment is needed, including surgical resection, targeted therapy by biological agents according to molecular testing gene mapping, chemotherapy, radiation therapy, and immunotherapy. It is of great importance to understand the updated guidelines and current treatment options. The extent of surgical intervention depends on the disease stage, ranging from simple cholecystectomy (T1a) to extended resections and including extended cholecystectomy (T1b), with wide lymph node resection in every case or IV-V segmentectomy (T2), hepatic trisegmentectomy or major hepatectomy accompanied by hepaticojejunostomy Roux-Y, and adjacent organ resection if necessary (T3). Laparoscopic or robotic surgery shows fewer postoperative complications and equivalent oncological outcomes when compared to open surgery, but much attention must be paid to avoiding injuries. In addition to surgery, novel targeted treatment along with immunotherapy and recent improvements in radiotherapy and chemotherapy (neoadjuvant-adjuvant capecitabine, cisplatin, gemcitabine) have yielded promising results even in inoperable cases calling for palliation (T4). Thus, individualized treatment must be applied.
