Objective

To identify predictors for back pain, leg pain, and activity limitation in patients with early persistent low back disorders (LBDs).

The Tougher the Better: An Economic Analysis of Increased Payment Thresholds on the Performance of General Practices

We investigate whether and how a change in performance‐related payment motivated General Practitioners (GPs) in Scotland. We evaluate the effect of increases in the performance thresholds required for maximum payment under the Quality and Outcomes Framework in April 2006. A difference‐in‐differences estimator with fixed effects was employed to examine the number of patients treated under clinical indicators whose payment schedules were revised and to compare these with the figures for those indicators whose schedules remained unchanged. The results suggest that the increase in the maximum performance thresholds increased GPs' performance by 1.77% on average. Low‐performing GPs improved significantly more (13.22%) than their high‐performing counterparts (0.24%). Changes to maximum performance thresholds are differentially effective in incentivising GPs and could be used further to raise GPs' performance across all indicators.

Synthesis of two potent glucocorticoid receptor agonists labeled with carbon‐14 and stable isotopes

Two potent glucocorticoid receptor agonists were prepared labeled with carbon‐14 and with stable isotopes to perform drug metabolism, pharmacokinetics, and bioanalytical studies. Carbon‐14 labeled (1) was obtained from an enantiopure alkyne (5) via a Sonogashira coupling to a previously reported 5‐amino‐4‐iodo‐[2‐¹⁴C]pyrimidine [¹⁴C]‐(6), followed by a base‐mediated cyclization (1) in 72% overall radiochemical yield. Carbon‐14 labeled (2) was prepared in five steps employing a key benzoic acid intermediate [¹⁴C]‐(13), which was synthesized in one pot from enolization of trifluoromethylketone (12), followed by bromine–magnesium exchange and then electrophile trapping reaction with [¹⁴C]‐carbon dioxide. A chiral auxiliary (S)‐1‐(4‐methoxyphenyl)ethylamine was then coupled to this acid to give [¹⁴C]‐(15). Propargylation and separation of diastereoisomers by crystallizations gave the desired diastereomer [¹⁴C]‐(17) in 34% yield. Sonogashira coupling to iodopyridine (10) followed by cyclization to the azaindole [¹⁴C]‐(18) and finally removal of the chiral auxiliary gave [¹⁴C]‐(2) in 7% overall yield. For stable isotope syntheses, [¹³C₆]‐(1) was obtained in three steps using [¹³C₄]‐(6) and trimethylsilylacetylene‐[¹³C₂] in 26% yield, while [²H₅]‐(2) was obtained by first preparing the iodopyridine [²H₅]‐(10) in five steps. Then, Sonogashira coupling to chiral alkyne (24) and cyclization gave [²H₅]‐(2) in 42% overall yield.     

Psychometric Properties of a Scale on Judgmental Communication with Peers About Sex Among YMSM and Their Close Friends in Lebanon

Lemierre's syndrome: a report of six cases

OBJECTIVE: Lemierre's syndrome is a rare but severe condition combining pyrexia, cervical pain and pulmonary signs following a pharyngeal infection, usually tonsillitis. This infectious disease is still present in our country despite wide use of antibiotic therapy in pharyngeal infections. METHODS: In a retrospective study conducted between 1995 and 2000 in two departments (infectious diseases and critical care unit) of Nice university hospital (Nice, France), we collected and analysed six cases of Lemierre's syndrome. RESULTS: We describe a serie of 6 cases, all of them female patients of mean age 27. We enrolled healthy patients whose initial symptom was tonsillitis. Most of these patients showed signs of severe sepsis and one died of septic shock. All the others recovered with treatment. The mean time between tonsillitis and first sign of sepsis was seven days. In four cases, patients received a beta- lactam antimicrobial agent with metronidazole. In two cases, patients were treated with amoxicillin-clavulanate. All patients were investigated for the presence of internal jugular vein thrombosis and were treated by anticoagulants when research was positive. CONCLUSIONS: A strong presumptive diagnosis can be made on the basis of clinical presentation, secondarily confirmed by para-clinical data. The prognosis depends on the speed and quality of management. We therefore wished to raise awareness of this condition among our colleagues by reporting our personal experience.     

Mauling of the “Celtic Tiger”: Clinical characteristics and outcome of first-episode depression secondary to the economic recession in Ireland

Background

There is a dearth of studies describing clinical characteristics and outcome of patients who present with mood disorders related to economic recession.

Aims

To describe a cohort of patients admitted with first-episode depression related to the Irish economic recession and compare this cohort with all other first-episode depressives admitted during the same time period (2009–2010).

Methods

A cohort of 137 patients admitted with first-episode depression to an independent university teaching hospital was prospectively identified and followed up from admission over 2 years (mean follow-up 430 days, s.d. 176 days). The cohort was divided into “Celtic Tiger” (patients with first-episode depression secondary to the economic recession) and non-Celtic Tiger control patients (other first-episode depressed patients). Both groups were compared in terms of clinical characteristics at baseline and outcome over follow-up.

Results

The number of admissions due to first depressive episodes were higher in recession years 2009/10 than in pre-recession years 2008/9. Celtic Tiger patients were predominantly male and more severely depressed with more marked suicidal ideation (χ², p<0.001) than control patients. They were more likely to recover (χ², p=0.013), less likely to recur (χ², p<0.001) and had faster time to recovery (log rank, p<0.001) and slower time to full recurrence (log rank, p=0.001). The Celtic Tiger patients spent more time asymptomatic and less time at full and subthreshold depression levels over follow-up.

Limitations

Study setting of centre specializing in affective disorders treatment, retrospective nature of follow-up after initial prospective interview and lack of patient follow-up interview.

Conclusion

The study describes a subgroup of patients with severe depression associated with economic recession with likely high suicide risk but very favourable outcome.     

Mutations in protein N-arginine methyltransferases are not the cause of FTLD-FUS

The nuclear protein fused in sarcoma (FUS) is found in cytoplasmic inclusions in a subset of patients with the neurodegenerative disorder frontotemporal lobar degeneration (FTLD-FUS). FUS contains a methylated arginine–glycine–glycine domain that is required for transport into the nucleus. Recent findings have shown that this domain is hypomethylated in patients with FTLD-FUS. To determine whether the cause of hypomethylation is the result of mutations in protein N-arginine methyltransferases (PRMTs), we selected 3 candidate genes (PRMT1, PRMT3, and PRMT8) and performed complete sequencing analysis and real-time polymerase chain reaction mRNA expression analysis in 20 FTLD-FUS cases. No mutations or statistically significant changes in expression were observed in our patient samples, suggesting that defects in PRMTs are not the cause of FTLD-FUS.
