Is Flexible Shared Workspace Model Truly Beneficial for the Users? A Review of Costs and Benefits

With the advancement in technology along with the changes in consumer behaviour, flexible shared workspace which is a new model in the workspace concept has become increasingly popular. Although abstract evidence is available on benefits as well as on the costs of these workspaces in a disorderly manner, comprehensive and scientific evidence is not properly and recently reviewed to identify the costs and the benefits of these flexible shared workspaces. Thus, a clear knowledge gap exists on whether these spaces are truly beneficial for their users. Intending to fill this knowledge gap, the main purpose of this study directs towards identifying the costs and benefits of using shared workspaces. The study findings will be useful for current and future shared workspace users when making decisions on selecting spaces for their work and also for space providers in order to identify the areas that they should improve to attract more customers. This study was done through a comprehensive literature review and 21 quantitative, qualitative and mixed approach articles published on flexible workspace context during the years from 2000 to 2022 were reviewed. The findings of this study reveal that the costs are mostly related to the areas of privacy, productivity, control, psychological concerns, cost and ergonomics while the benefits relate to a high level of flexibility, collaboration, knowledge sharing, networking, performance and low cost. The authors propose future researchers to conduct research studies to validate these findings empirically. © 2022 The Authors.

A content analysis of district level health data in Uttar Pradesh, India

The study aimed to conduct a content analysis of the different types of public health data maintained by the Health Department, the Department of Women and Child Development, and the private for profit and not for profit health sectors and the links that exist between them in terms of data sharing. Method: In two districts, Sitapur and Unnao, an IDEAS/PHFI study team visited district, sub-district and village level health facilities (public and private) as well as NRHM programme management units, and Women and Child Development offices. The team collected all available forms and interviewed facility staff and programme managers to understand the types of data collected, their flow and data sharing. Case studies of three not-for-profit non-governmental organisations were developed to understand how they maintain and share data with the public health system. Findings: The public health system collects a large volume of health data; Data exist for all of WHO’s health system building blocks, but it is unevenly distributed. There are fewer data on contextual information, e.g. village infrastructure and demographic profile, compared to service delivery; There is little formal or institutional routine data sharing between the public and private health sectors, and between the health department and other related departments such as Women and Child Development

Restriction Fragment Length Polymorphism (RFLP) of the Internal Transcribed Spacer 1 (ITS1) region of cutaneous leishmaniasis causing Leishmania donovani in Sri Lanka

Objectives: To isolate PCR quality DNA from punch biopsy samples of 35 suspected cutaneous leishmaniasis (CL) lesions, carry out Internal Transcribed Spacer 1 (ITS1) PCR, analyse Restriction Fragment Length Polymorphism (RFLP), sequence of ITS1 region of 10 randomly selected patient samples and to determine the genetic variation among the causative parasites.Methods: Punch biopsies (3mm) from CL lesions (n=35) were taken and stored in NET buffer at -20C. DNA was extracted using a commercially available kit. ITS1 PCR was carried out using previously described primers. PCR products were digested with Haelll, run in a 1.7 % ethidium bromide gel and visualized under UV light. Same ITS1 PCR products of 10 randomly selected samples were sequenced commercially. Analysis of sequences was carried out with CLUSTALW2 multiple sequence analyzing software.Results: All 35 CL samples showed the same Leishmania donovani ITS1 RFLP pattern. The BLAST search confirmed that the 10 sequenced Sri Lankan strains belong to L. donovani. Multiple sequences analysis showed that Sri Lankan L. donovani strains are highly homogenous in the ITS1 regions. However, the Sri Lankan strains showed, few indels in the ITS1 region when compared with the L. donovani ITS1 sequences originated from India, Sudan and Ethiopia.Conclusions: Cutaneous leishmaniasis in Sri Lanka is still caused only by L. donovani and ITS1 region of the L. donovani strain of Sri Lankan origin is highly homogenous and conserved

Two major tyrosine protein kinases of resting human T lymphocytes are down-regulated following mitotic stimulation

AbstractHuman lymphocyte tyrosine protein kinases (TPKs) have been analyzed by gel-filtration chromatography. The major TPK species with activity towards an exogenous tyrosine-containing peptide had molecular masses of 70–100 kDa (TPK I) and 35–40 kDa (TPK II). TPKs I and II were distinct from the well-characterized autophosphorylating lymphoid cell TPK, pp56lck [(1983) J. Biol. Chem. 258, 10738–107421]. Both TPK I and TPK II were down-regulated following mitogenic stimulation of lymphocytes with phytohae-magglutinin. By contrast, pp56lck remained clearly detectable in stimulated lymphocytes. We suggest that TPKs I and II may play a role in the regulation of the lymphocyte cell cycle

Valsalva retinopathy in pregnancy: a case report

<p>Abstract</p> <p>Introduction</p> <p>Valsalva retinopathy is a unilateral or bilateral condition that occurs when increased intra-thoracic or intra-abdominal pressure transmitted to the eye causes a sharp rise in the intra-ocular venous pressure, and rupture of superficial retinal capillaries. The patient often gives a history of a recent strenuous physical act, which could have increased the intra-thoracic pressure. Pregnancy is known to be a risk factor for Valsalva retinopathy.</p> <p>Case presentation</p> <p>A 23-year-old woman in her seventh month of pregnancy presented with a history of decreased vision in her left eye of one-week duration. Examination of the affected eye showed best corrected visual acuity of 20/50, and fundus examination revealed a pre-retinal hemorrhage located in the macula. Based on clinical findings, the diagnosis of Valsalva retinopathy was made.</p> <p>Conclusion</p> <p>Retinal hemorrhages can be generated by Valsalva maneuvers. Pregnancy is a known risk factor for Valsalva retinopathy; however, the diagnosis should be made only after excluding other causes of retinal hemorrhages. It is a self-limited event. We report a case of Valsalva retinopathy complicating normal pregnancy and confirm that, to date, there is no evidence to indicate that there is a risk of recurrence following spontaneous vaginal delivery.</p

Use of a rapid diagnostic test to detect cutaneous leishmaniasis in Sri Lanka

Objectives: This study was initiated to determine the sensitivity and specificity of a commercially available rapid diagnostic test (RDT) to detect leishmania antigen in cutaneous leishmaniasis(CL) skin lesions among Sri Lankan patients compared to PCR and Slit skin smear(SSS).Methods: Patients clinically suggestive of CL lesions were subjected to parasitological investigations. The clinical history was collected by the researcher. Samples were collected by a qualified trained medical officer from the suspected CL lesions at the dermatology clinic in the Hambantota hospital and from the patients coming to the Department of Parasitology, Faculty of Medical Sciences, University of Sri Jayewardenepura. RDT was done at the Hambantota hospital and samples were brought to the Department of Parasitology, to perform SSS, PCR and cultures.Results: Fifty samples have been collected thus far and PCR was performed only in 48 samples. Out of the 50 samples only 9 were positive by RDT and 32 by SSS and PCR. The 9 samples that were positive for RDT were positive by SSS and 7 positive by PCR. Of the 41 samples that were negative by RDT, 16 were negative by PCR as well as SSS.Conclusions: From the data collected it can concluded that RDT is not the best method to diagnose CL skin lesions in patients in Sri Lanka. Also it confirms that the best method to diagnose leishmaniasis is PCR

Interferon-gamma release assay (IGRA) conversion, reversion and implications for the diagnosis of latent tuberculosis infection using a multimodality approach: a retrospective, observational study within a central London TB centre

Introduction and Objectives Accurate diagnosis & management of latent tuberculosis infection (LTBI) among TB contacts is critical for both the health of infected individuals and prevention of disease transmission. Interferon gamma release assays (IGRAs) measure T cell release of interferon-gamma following stimulation by antigens not confounded by the BCG vaccination. The current NICE guidelines recommend their use following a positive TST. In addition some centres have moved to a single step IGRA test for LTBI. Our institution adopts a triple investigation approach comprising a chest radiograph (CXR), TST and IGRA on presentation followed by a rescreen if the TST & IGRA are discordant or if pulmonary contacts are screened prior to 6 weeks. The aim of our study was to evaluate the prevalence of IGRA conversion and reversion in rescreened asymptomatic TB contacts that attended our centre. Methods This was a retrospective, observational study carried out at a central London teaching hospital. The study population comprised 593 consecutive, adult TB contacts screened between 1 January 2008 and 31 December 2010. Data were collected through retrospective review of chest radiographs, TST & IGRA tests. Results Of 498 asymptomatic TB contacts screened, 460 had both an initial TST and IGRA performed (Abstract P13 figure 1). 81 (17.7%) contacts had discordant TST & IGRA results. 52 (64%) of these discordant cases had a positive TST & Negative IGRA; these patients would have been discharged under NICE guidelines however, our rescreen revealed 9 (17%) positive 2nd IGRAs that is, conversion. Three of these patients were under 35 and would therefore by eligible for chemoprophylaxis. Twenty-nine (36%) of the discordant cases had a negative TST and positive IGRA however, 8 (28%) of these IGRAs reverted to negative. It is important to note that if following a single-step IGRA screening protocol (ie, without a rescreen) these cases may have been commenced on chemoprophylaxis unnecessarily (four of these reversion cases were under the age of 35). Conclusions Our results show that adoption of either a sequential TST + ve/IGRA approach or single IGRA approach can result in a significant number of false negative LTBI diagnoses due to IGRA conversion. Conversely, we have also shown that an IGRA rescreen because of discordant TST/IGRA tests can improve LTBI diagnostic specificity and therefore reduce unnecessary chemoprophylaxis due to the effect of reversion
