Social media in travel medicine: a review. - Travel medicine and infectious disease
The use of social media is widespread and provides new opportunities for healthcare professionals and healthcare organisations to interact with patients, the public, policy makers, and each other. Social media offers the possibility of providing users with up-to-date information when, where, and how they want it, but it also brings with it some challenges. With increasing use of social media, there is potential to change the way travel medicine is delivered; practitioners should consider how to exploit the benefits in their practice, and not be afraid to experiment. However they need to be cognizant of the potential pitfalls. The information exchanged requires careful application as it may not always achieve the desired outcome, it needs to be monitored for quality, accuracy, and reliability, and confidentiality and privacy must be maintained. Most importantly, as social media becomes more sophisticated and widely adopted in the healthcare arena, further evaluation and research is required to understand its impact and its application to travel medicine.Copyright © 2015 Elsevier Ltd.

Warfarin-induced deep vein thrombosis. - International medical case reports journal
We are presenting a 72-year-old female who was admitted to hospital with deep vein thrombosis (DVT). She was known to have atrial fibrillation and was initiated on warfarin for stroke prophylaxis 3 days earlier. She was given warfarin therapy without low molecular weight heparin cover as per "slow-start regimen" protocol. The warfarin dose was increased after 3 days to achieve rapid anticoagulation, resulting in DVT in the left leg. We propose that the higher unopposed warfarin dose utilized in this case resulted in DVT. Warfarin loading doses may paradoxically result in a hypercoagulable state and potential clot formation because of significant reductions in protein C and protein S levels.
Compliance with long-term malaria prophylaxis in British expatriates. - Travel medicine and infectious disease
There were 219 million cases of malaria with 600,000 deaths in 2010. Current UK guidance recommends malaria chemoprophylaxis for travellers to malaria endemic areas. Despite proven efficacy, compliance amongst long-term travellers with prophylaxis and personal protective strategies is sub-optimal. This survey assesses compliance rates amongst Foreign and Commonwealth Office employees on placement in malaria endemic areas and establishes the rationale for their decisions.A Survey Monkey questionnaire was circulated to Foreign and Commonwealth Office employees on long-term placement in endemic areas. This ascertained background knowledge of malaria, compliance with prevention strategies and the rationale for decisions made.The response rate was 56.5% (327 of 579); responses showed a good knowledge of malaria. 59% of respondents continued their prophylaxis for 0-3 months only. No pregnant women reported compliance of greater than 95%. More than half of the individuals with a compliance of <25% cited concerns about long term safety. 39.5% of respondents reported significant side-effects to chemoprophylaxis. 12.8% reported contracting malaria.Despite being well informed, poor adherence was reported, especially amongst pregnant respondents. The majority of individuals ceased medication within three months. Concern regarding the safety of long-term medication was the major barrier. Suggestions are made regarding optimisation of compliance or alternative strategies.Copyright © 2014 Elsevier Ltd. All rights reserved.
Yellow fever vaccination: is one dose always enough? - Travel medicine and infectious disease
In March 2013, the World Health Organization (WHO) Strategic Advisory Group of Experts on Immunisation (SAGE) considered a number of issues in order to update the WHO Position Paper on Yellow Fever (2003). A key conclusion of this review was that a single dose of yellow fever (YF) vaccine appears to confer life-long protection against YF disease, and that a booster dose of YF vaccine is not needed to maintain immunity. While the efficacy of YF vaccine in the majority of vaccine recipients is not in doubt, the WHO announcement is somewhat surprising as there are some limitations in the evidence base, but more importantly, this announcement is not accompanied by any imminent change in the International Health Regulations 2005. The tension between what is considered best clinical practice and the law will be difficult to reconcile for many health professionals, travellers, and the travel industry, in an area of travel medicine that is already subject to debate and confusion. This commentary reviews the recent WHO announcement, and considers the practical implications for health professionals providing YF vaccine to international travellers.Copyright © 2013 Elsevier Ltd.

Reductive assembly of cyclobutadienyl and diphosphacyclobutadienyl rings at uranium. - Nature communications
Despite the abundance of f-block-cyclopentadienyl, arene, cycloheptatrienyl and cyclo-octatetraenide complexes, cyclobutadienyl derivatives are unknown in spite of their prevalence in the d-block. Here we report that reductive [2+2]-cycloaddition reactions of diphenylacetylene and (2,2-dimethylpropylidyne)phosphine with uranium(V)-inverted sandwich 10π-toluene tetra-anion complexes results in the isolation of inverted sandwich cyclobutadienyl and diphosphacyclobutadienyl dianion uranium(IV) complexes. Computational analysis suggests that the bonding is predominantly electrostatic. Although the ψ4 molecular orbital in the cyclobutadienyl and diphosphacyclobutadienyl ligands exhibits the correct symmetry for δ-bonding to uranium, the dominant covalent contributions arise from π-bonding involving ψ2 and ψ3 orbital combinations. This contrasts with uranium complexes of larger arenes and cyclo-octatetraenide, where δ-bonding dominates. This suggests that the angular requirements for uranium to bond to a small four-membered ring favours π-bonding, utilizing 5f- instead of 6d-orbitals, over δ-bonding that is favoured with larger ligands, where 6d-orbitals can become involved in the bonding.
Development and Validation of RP-HPLC Method for Simultaneous Estimation of Cefpodoxime Proxetil and Dicloxacillin Sodium in Tablets. - Indian journal of pharmaceutical sciences
A simple, accurate, rapid and precise reversed-phase high-performance liquid chromatographic method has been developed and validated for simultaneous determination of cefpodoxime proxetil and dicloxacillin sodium in tablet. The chromatographic separation was carried out on kromasil C18 analytical column (250×4.6 mm; 5 μm) with a mixture of acetonitrile:methanol:trifloroacetic acid (0.001%) with pH 6.5 (30:50:20, v/v/v) as mobile phase; at a flow rate of 1.0 ml/min. UV detection was performed at 235 nm. The dicloxacillin sodium and cefpodoxime proxetil were eluted at 1.92 and 3.35 min, respectively. The peaks were eluted with better resolution. Calibration plots were linear over the concentration range 0.5-20 μg/ml for cefpodoxime proxetil (r(2)=0.9996) and 5-50 μg/ml for dicloxacillin sodium (r(2)=0.9987). The method was validated for accuracy, precision, linearity and specificity. The method was very sensitive with limit of detection 0.0726, 0.3685 μg/ml and limit of quantification 0.220, 1.116 μg/ml for cefpodoxime proxetil and dicloxacillin sodium, respectively. The high recovery and low relative standard deviation confirm the suitability of the method for routine determination of cefpodoxime proxetil and dicloxacillin sodium in bulk drug and tablet dosage form.
A triamido-uranium(V) inverse-sandwich 10Ï€-toluene tetraanion arene complex. - Dalton transactions (Cambridge, England : 2003)
Reduction of [U(Ts(Tol))(Cl)(μ-Cl)U(Ts(Tol))(THF)2] [2, Ts(Tol) = HC(SiMe2NAr')3; Ar' = 4-MeC6H4)] with KC8 in toluene afforded the new arene-bridged diuranium complex [{U(Ts(Tol))}2(μ-η(6):η(6)-C6H5Me)] (3); combined structural, spectroscopic, magnetic, and computational analyses unambiguously confirm that the uranium centres in 3 are in the +5 oxidation state and the toluene is a 10π-tetraanion.
Formulation of thermoresponsive and buccal adhesive in situ gel for treatment of oral thrush containing poorly water soluble drug bifonazole. - Journal of pharmacy & bioallied sciences
The aim of the present work is to formulate and evaluate in situ oral topical gels of poorly water soluble drug Bifonazole based on temperature induced systems for the treatment of oral candidiasis. Bifonazole is poorly water soluble and low permeable drug means it's belongs to BCS Class IV. Due to its poor water solubility, it necessary to enhance solubility in water by make complex with Beta- Cyclodextrin (Drug to βCyclo Dextrine ratio is 1:1). After in situ gel preparation done by using Poloxamer (10% and 15%w/w) along with carbopol 934 (0.2 to 1.0% w/w) and Bifonazole - β CD complex (1%w/w). The formulations were evaluated for physiochemical parameter, gelation Temperature, viscosity, gel strength, content uniformity mucoadhesive force, Diffusion Study.
The nature of unsupported uranium-ruthenium bonds: a combined experimental and theoretical study. - Chemistry (Weinheim an der Bergstrasse, Germany)
Four new uranium-ruthenium complexes, [(Tren(TMS))URu(η(5)-C(5)H(5))(CO)(2)] (9), [(Tren(DMSB))URu(η(5)-C(5)H(5))(CO)(2)] (10), [(Ts(Tolyl))(THF)URu(η(5)-C(5)H(5))(CO)(2)] (11), and [(Ts(Xylyl))(THF)URu(η(5)-C(5)H(5))(CO)(2)] (12) [Tren(TMS)=N(CH(2)CH(2)NSiMe(3))(3); Tren(DMSB)=N(CH(2)CH(2)NSiMe(2)tBu)(3)]; Ts(Tolyl)=HC(SiMe(2)NC(6)H(4)-4-Me)(3); Ts(Xylyl)=HC(SiMe(2)NC(6)H(3)-3,5-Me(2))(3)], were prepared by a salt-elimination strategy. Structural, spectroscopic, and computational analyses of 9-12 shows: i) the formation of unsupported uranium-ruthenium bonds with no isocarbonyl linkages in the solid state; ii) ruthenium-carbonyl backbonding in the [Ru(η(5)-C(5)H(5))(CO)(2)](-) ions that is tempered by polarization of charge within the ruthenium fragments towards uranium; iii) closed-shell uranium-ruthenium interactions that can be classified as predominantly ionic with little covalent character. Comparison of the calculated U-Ru bond interaction energies (BIEs) of 9-12 with the BIE of [(η(5)-C(5)H(5))(3)URu(η(5)-C(5)H(5))(CO)(2)], for which an experimentally determined U-Ru bond disruption enthalpy (BDE) has been reported, suggests BDEs of approximately 150 kJ mol(-1) for 9-12.Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

Validated RP-HPLC and TLC methods for simultaneous estimation of tamsulosin hydrochloride and finasteride in combined dosage forms. - Acta pharmaceutica (Zagreb, Croatia)
Reversed-phase high-performance liquid chromatography (RP-HPLC) and thin-layer chromatography (TLC) methods have been developed and validated for simultaneous estimation of tamsulosin hydrochloride and finasteride in bulk drug and in combined dosage forms. RP-HPLC separation was achieved on a Phenomenex C18 column using methanol/0.02 mol L-1 ammonium acetate buffer/triethylamine (79.9 + 20 + 0.1, V/V/V) (pH 9.2) as mobile phase. TLC separation was achieved on an aluminium-backed layer of silica gel 60 F254 using toluene/methanol/triethylamine (9 + 1.5 + 1, V/V/V) as eluent. Quantification was achieved with photodiode array (PDA) detection at 235 nm over the concentration range 0.5-16 and 1-50 μg mL-1 with mean recovery of 99.8 ± 0.9 and 100.0 ± 0.8% for tamsulosin hydrochloride and finasteride, respectively, by the RP-HPLC method. Quantification was achieved with UV detection at 270 nm over the concentration range 100-2000 ng per spot and 250-5000 ng per spot with mean recovery of 98.9 ± 0.9 and 99.6 ± 0.7 % for tamsulosin hydrochloride and finasteride, respectively, by the TLC method. Both methods are simple, precise, accurate and sensitive and are applicable to the simultaneous determination of tamsulosin hydrochloride and finasteride in bulk drug and in combined dosage forms.
