Challenges and Opportunities for Developing Countries from Medical Tourism
Wikipedia defines âMedical Tourismâ as the act of traveling to other countries to obtain medical, dental and surgical care. Rapid expansion of facilities for patients abroad has helped to spur this industryâs growth. Regardless of the destination, U.S. citizens are increasingly embracing the benefits of medical tourism due to dramatically rising U.S. healthcare costs. Medical care in countries such as India, Mexico, Thailand and Singapore can cost as little as ten percent of the cost of comparable care in the U.S. for some procedures. Statistical analysis revealed the costs to be significantly lower for many of these countries. Currently, patients from U.S., Canada, Europe, Australia and the Middle East appear to be traveling to destinations in Asia such as India and in Central America such as Mexico for medical care. Medical tourism can offer opportunities to developing countries to make improvements in their country and the host country can enjoy the economic benefit from medical tourism. However, there are also some challenges they may face from medical tourism. This paper discusses the opportunities and the challenges resulting from medical tourism for developing countries

Persistent dermatomal eruption on a leg
Unilateral linear capillaritis (ULC) is a rare variant of pigmented purpuric dermatoses (PPD) that is characterized by a linear or pseudo-dermatomal eruption on a single extremity. Although clinically distinct from the other PPD, it shares histopathologic features with this group. Herein, we present a man in his 50s who presented with asymptomatic macules and scaly papules on the left lower extremity in a linear distribution. The eruption persisted despite treatment with topical triamcinolone 0.1% and oral rutocide
The Indiana University Student Outreach Clinic as a Substrate for Interprofessional Education: A Physical Therapy Perspective
poster abstractPurpose
The World Health Organization defines Inter-Professional Education (IPE) as âtwo or more professions learning about, from and with each other to enable effective collaboration &improve health outcomes.â IPE is being stressed in education to prepare students for Inter-Professional Care (IPC). IPC occurs when multiple health workers from different professional backgrounds provide comprehensive health services. Our purpose is to discuss the Indiana University Student Outreach Clinic (IU-SOC) as an exemplar in IPE/IPC in preparing PT students for clinical practice.
Description
The IU-SOC has implemented IPE/IPC by collaborating with partners from the schools of medicine, pharmacy, law, social work, dentistry, and most recently, physical therapy. Student leaders collaborate to provide comprehensive patient care. Different committees are in place to facilitate communication between disciplines. One PT student is designated in the IPE role to assist other partners in determining if a patient is appropriate for PT. This model has allowed PT to communicate reciprocally with medicine to ensure best patient care.
Summary of Use
IU-SOC is unique because it is a student-run pro bono clinic where teaching IPE/IPC is a primary purpose. Students benefit from this model by learning the importance of communication between disciplines early in their education to better prepare for IPC; making them more likely to utilize it during clinical practice. The community has increased access to services and is utilizing healthcare resources more efficiently, with less reliance on emergency services. Occupational Therapy is anticipated to join rehab services in the near future.
Importance to Members
IPC helps to sustain the health care system, improve outcomes, enhance organizational efficiency, and provide more comprehensive care. IPC is the future of health care; the foundation of which must be established in education. Multi-disciplinary, student-led outreach clinics, such as IU-SOC, can serve as an IPE/IPC substrate to prepare PT students for practice
Two Patients with Extremely Elevated Tumor Markers: Where Is the Malignancy?
Serum tumor markers are useful to evaluate a cancer's response to treatment, for early detection of cancer relapse, and, in some cases, to diagnose malignancy. In this paper, we present two patients with significantly elevated serum tumor markers without evidence of malignant disease. An 18-year-old patient suffering from autoimmune hepatitis had markedly increased alpha-fetoprotein (aFP) levels (2,002âÎŒg/L; normal <10âug/L). Extensive imaging showed no signs of hepatocellular carcinoma or other cancer, and treatment with Prednisone led to rapid normalization of both liver enzymes and aFP. The second patient, a 60-year-old female with painless jaundice due to biliary stone disease, had very high serum levels of CA19-9 (18,000âkU/L, normal <27âkU/L). Liver biochemistry and serum CA19-9 concentration decreased to almost normal values (45âkU/L) after biliary stenting. These cases demonstrate that serum tumor markers can be elevated in benign disease and are therefore not appropriate to diagnose cancer
Family history is neglected in the work-up of patients with colorectal cancer: a quality assessment using cancer registry data
In the diagnostic work-up of hereditary non-polyposis colorectal cancer (HNPCC, Lynch syndrome), high-risk patients can be identified using information from the family history on cancer (âAmsterdam criteriaâ and âBethesda guidelinesâ). To investigate to what extent the medical specialists apply these criteria to patients with colorectal carcinoma and a suspicion of HNPCC, we collected information on diagnostic work-up of 224 patients of seven hospitals in the region of the Comprehensive Cancer Centre West in Leiden, The Netherlands. These patients were diagnosed with colorectal cancer between 1999 and 2001 and satisfied at least one of the Bethesda guidelines. A complete family history was recorded for 38 of the 244 patients (16%). Patients with a complete family history were more likely to be referred to the Clinical Genetic Centre than those with an incomplete or absent family history (53% vs. 13% and 4%, respectively; PÂ <Â 0.0001), and more likely to be analyzed for microsatellite instability (MSI), which is a characteristic of HNPCC (34% vs. 6% and 1%, respectively; PÂ <Â 0.0001). We conclude that the family history is neglected in the majority of patients with colorectal cancer and MSI-analysis is only performed in a small proportion of the patients that meet the guidelines for this analysis
Alteration of the Exhaled Volatile Organic Compound Pattern in Colorectal Cancer Patients after Intentional Curative SurgeryâA Prospective Pilot Study
As current follow-up modalities for colorectal carcinoma (CRC) have restricted sensitivity, novel diagnostic tools are needed. The presence of CRC changes the endogenous metabolism, resulting in the release of a specific volatile organic compounds (VOC) pattern that can be detected with an electronic nose or AeonoseTM. To evaluate the use of an electronic nose in the follow-up of CRC, we studied the effect of curative surgery on the VOC pattern recognition using AeonoseTM. A prospective cohort study was performed, in which 47 patients diagnosed with CRC were included, all of whom underwent curative surgical resection. Breath testing was performed before and after surgery using the AeonoseTM. A machine learning model was developed by discerning between the 94 pre-and postoperative breath samples. The training model differentiated between the pre-and postoperative CRC breath samples with a sensitivity and specificity of 0.78 (95%CI 0.61â0.90) and 0.73 (95%CI 0.56â0.86), respectively, with an accuracy of 0.76 (95%CI 0.66â0.85), and an area under the curve of 0.79 (95%CI 0.68â0.89). The internal validation of the test set resulted in an accuracy of 0.75 (95%CI 0.51â0.91) and AUC of 0.82 (95%CI 0.61â1). In conclusion, our results suggest that the VOC pattern of CRC patients is altered by curative surgery in a short period, indicating that the exhaled VOCs might be closely related to the presence of CRC. However, to use AeonoseTM as a potential diagnostic tool in the clinical follow-up of CRC patients, the performance of the models needs to be improved through further large-scale prospective research.</p
The role of hole transport between dyes in solid-state dye-sensitized solar cells
In dye-sensitized solar cells (DSSCs)
photogenerated positive charges
are normally considered to be carried away from the dyes by a separate
phase of hole-transporting material (HTM). We show that there can
also be significant transport within the dye monolayer itself before
the hole reaches the HTM. We quantify the fraction of dye regeneration
in solid-state DSSCs that can be attributed to this process. By using
cyclic voltammetry and transient anisotropy spectroscopy, we demonstrate
that the rate of interdye hole transport is prevented both on micrometer
and nanometer length scales by reducing the dye loading on the TiO<sub>2</sub> surface. The dye regeneration yield is quantified for films
with high and low dye loadings (with and without hole percolation
in the dye monolayer) infiltrated with varying levels of HTM. Interdye
hole transport can account for >50% of the overall dye regeneration
with low HTM pore filling. This is reduced to about 5% when the infiltration
of the HTM in the pores is optimized in 2 ÎŒm thick films. Finally,
we use hole transport in the dye monolayer to characterize the spatial
distribution of the HTM phase in the pores of the dyed mesoporous

Narrowing the Tolerance Factor Limits for Hybrid Organic-Inorganic Dicyanamide-Perovskites
[Abstract] In this work we focus in setting the limits of the tolerance factor and the size of the A-cations that stabilize the perovskite structure in hybrid dicyanamide compounds [A][Mn(dca)3]. For this purpose, we propose an alternative, simple approach to calculate a more realistic effective ionic radius for the large and anisotropic A-cations often present in these type of compounds. We test the proposed procedure by analysing the crystal structures of [A][Mn(dca)3] dicyanamide hybrids reported in the literature and recalculating the tolerance factors of such compounds, as well as by preparing five new [A][Mn(dca)3] members, discussing also the influence of the A-cation shape in the stability limits of the perovskite structure. Interestingly, such methodology is not only useful to develop new compounds of the emerging family of (multi)functional multi(stimuli)-responsive dicyanamide materials but can also be applied to other hybrid organic-inorganic perovskites and related materials.As for financial support, the authors thank Ministerio de EconomĂa y Competitividad MINECO and EU-FEDER (projects MAT2017-86453-R and PDC2021-121076-I00), and Xunta de Galicia for the collaboration agreement âDevelopment of research strategic actions Universidade da Coruña I â+ âD â+ âi 2021â2022: CICA-Disrupting Projects 2021SEM-A3 (NanoCool).
