Long-term impact of the 2008 economic crisis in Spain on road traffic collisions mortality by socioeconomic position

We aimed to assess the effect of the 2008 crisis on road traffic collision (RTC) mortality in Spain, by socioeconomic position (SEP) and type of road use. This prospective, country-wide study covered all adults living in Spain and aged ≥30 years in November 2001. The long-term effect of the crisis was assessed by measuring the monthly percentage change (MPC) in RTC mortality between the pre-crisis (2002-2007) and crisis period (2008-2011). During the recession, RTC mortality fell more in people with low compared to high SEP, so MPCs difference between periods were of a higher magnitude in the low compared to high SEP groups, especially among men motorcyclists. RTC mortality trends were favorable following the 2008 crisis, particularly among low-SEP groups. In men motorcyclists, the upward trend of the pre-crisis period reversed course.

The incorporation of HIV self-testing as an exclusive option among men who have sex with men in Spain: results of an online cross-sectional study

Background

We assessed to what extent HIV self-testing would be incorporated by men who have sex with men (MSM) with previous testing history as their exclusive testing option and describe what actions they would take in the case of obtaining a reactive self-test.

Methods

We conducted an online survey among Spanish resident MSM recruited mainly in gay dating apps and analyze 6171 ever tested individuals. We used Poisson regression to estimate factors associated with the incorporation of self-testing as the exclusive testing option. Among those who would incorporate self-testing as their exclusive option, we described actions taken if obtaining a reactive self-test by number of tests in the past.

Results

Nearly half of the participants (48.3%) were > =35 years old, 84.6% were born in Spain, 57.9% had attained a university degree, 55.1% lived in a municipality of ≤500.000 and 86.4% self-identified as homosexual. For 37.2%, self-testing would become their exclusive testing option. The incorporation of self-testing as the exclusive option increased with age 25–34 (PR:1.1, 95%CI:1.0–1.3), 35–44 (PR:1.3, 95%CI:1.2–1.5), 45–49 (PR:1.5, 95%CI:1.3–1.7) and > 50 (PR:1.5, 95%CI:1.3–1.8) and in those who reported unprotected anal intercourse (PR:1.1, 95%CI:1.0–1.2) or having paid for sex (PR:1.2, 95%CI:1.0–1.3) in the last 12 months. It was also associated with having had < 10 HIV test in the past (2–9 tests (PR:1.3, 95%CI:1.1–1.4); 1 test (PR:1.5, 95%CI:1.3–1.7)), and having been tested ≥2 years (PR:1.4, 95%CI:1.3–1.5) or between 1 and 2 years ago (PR:1.1, 95%CI:1.0–1.2). Of participants who would use self-testing exclusively 76.6% would confirm their result in case of obtaining a reactive self-test and only 6.1% wouldn’t know how to react. Only one individual expressed that he would do nothing at all.

Conclusion

HIV self-testing could become the exclusive testing option for more than a third of our participants. It was chosen as the exclusive option especially by older, at risk and under-tested MSM. Self-testing strategies need to especially consider the linkage to care process. In this sense, only a small fraction would not know how to react and virtually nobody reported taking no action if obtaining a reactive result.

Arterio-venous malformation of the mandible. Case report and review of literature

Arteriovenous malformation (AVM) of the head and neck is a rare and potentially life threatening entity due to massive haemorrhage. There are several indications for treatment, including age of the patient and location, extent and type of vascular malformation. Endovascular therapy can effectively cure most lesions with limited tissue involvement. Surgery can be used in selected cases in combination with embolization. Here we report the case of a young woman affected by a massive AVM on the left side of the mandible and submandibular region, and also review the literature on AVM with special attention to treatment strategies.

Quality of life in a community sample of young cocaine and/or heroin users: the role of mental disorders

PURPOSE

Drug addiction and psychiatric disorders are frequently concomitant; however, few studies have investigated the impact of psychiatric disorders other than substance use disorder (SUD) on health-related quality of life (HRQoL) in drug users not in treatment. We studied the association of psychiatric disorders other than SUD with HRQoL in a street-recruited sample of cocaine and/or heroin users.

METHODS

It is a cross-sectional study involving 287 young users of cocaine and/or heroin in Barcelona, Spain. HRQoL was assessed with the Nottingham health profile (NHP). Patterns of drug use and mental disorders were assessed using the Spanish version of the psychiatric research interview for substance and mental disorders IV, and degree of dependence through the severity of dependence scale (SDS). The association of mental disorders with HRQoL was assessed through a Tobit regression analysis.

RESULTS

The overall NHP score was 23.9 (SD = 20.5, range 0-91.7). Sixty-one percent of the sample had two or more SUDs; 22 % had at least one non-SUD Axis I disorder (anxiety, mood, psychotic, or eating disorder); and 27.2 % had a borderline personality disorder (BPD) and/or antisocial personality disorder. Variables negatively associated with the global NHP score were psychosis [transformed beta coefficient: 15.23; 95 % confidence interval [CI] 4.48-25.97], BPD (9.55; 95 % CI 2.95-16.15), severity of dependence (8.12; 95 % CI 3.37-12.87), having two or more SUDs (for two or three SUDs: 6.83; 95 % CI 2.08-11.59) (>3 SUDs: 7.70; 95 % CI 1.72-13.68) and the intravenous use of some substance (10.20; 95 % CI 6.00-14.40).

CONCLUSION

HRQoL among street-recruited illegal substance users was impaired, particularly among those with psychiatric comorbidity, psychosis, and BPD being especially relevant.

A systematic review of evidence on the association between cocaine use and seizures

BACKGROUND

Institutional monographs/medical textbooks mention seizures as a neurological complication of cocaine, but no systematic reviews (SRs) have been published on this issue. We aimed to conduct a SR of the literature on the relationship between cocaine use and seizures and to summarize the biological plausibility of that relationship.

METHODS

The pathophysiological mechanisms that may underlie an association between cocaine and seizures were summarized; a SR was then performed using three databases (EMBASE, Medline, PsycINFO) and the Cochrane-library to search for published papers (1980-2012) aimed at quantifying the associations between cocaine use and seizures. The inclusion criteria for selection were: articles based on clinical trials, cohort, case-control (CC) or cross-sectional (CS) studies, participants ≥ 14 years old and not pregnant, and use of cocaine in the last 72 h. Information was extracted, evaluated and cross-checked independently by two researchers.

RESULTS

Of the 1243 potentially relevant articles initially identified; one CC and 22 CS studies were finally selected. The CC study did not find cocaine use to be a risk-factor for seizures. In addition to the limitations of the CS design, these studies had important methodological weaknesses and biases.

CONCLUSIONS

Despite its biological plausibility, no rigorous scientific evidence supports a causal relationship between cocaine use and seizures. The misinterpretation of the role of cocaine may have important implications in medical services. Well-conducted studies are urgently needed.

[Evolution of the need and coverage of syringe exchange programs in Spanish prisons, 1992-2009: A revised estimation]

INTRODUCTION

The objective of this paper is to amend the bias included in our previous work, presenting a corrected estimation of the need and coverage of syringes/needles in Spanish prisons between 1992 and 2009.

METHODS

Data on the provision of the needles exchange programs (NEPs) in prison is taken from official publications. The need was calculated by applying multiplicative methods to secondary data from several sources. Coverage was estimated as the quotient between provision and need and the difference between these magnitudes. The detected need estimate bias has been corrected.

RESULTS

NEP's in prisons started in 1997. Their maximum coverage reached 36% in 2005, which is much higher than the initially estimated value. However, it decreased by half in the next four years, reaching 17.4% in 2009.

CONCLUSION

The remarkable coverage reached by these programmes must be valued, but more recent evolution leads us to emphasize the need to be imaginative so that new epidemiological and economic circumstances do not lead to their disappearance.

[Evolution of the need and coverage of opioid substitution treatments and needle exchange programmes in Spanish prisons, 1992-2009]

INTRODUCTION

Spain is one of the few countries to have widely implemented opioid substitution treatments (OST) and needle exchange programmes (NEP) for drug users in prison. We analyze the evolution of the need, coverage and the timeliness of these interventions in Spain between 1992 and 2009.

METHODS

Data on the provision of interventions is taken from official publications. The need was calculated by applying multiplicative methods to secondary data from several sources. Coverage was estimated as the quotient between provision and need. Temporal opportunity was estimated by observing the gap between the acme of the incidence of consumption, of HIV infection or need and the curve of provision.

RESULTS

OST's began to be implemented in 1992. In 2002 they reached their maximum coverage (63.8%) and subsequently stabilized. NEP's started in 1997. Their maximum coverage reached 20.7% in 2006, but halved in a period of two years. The delay between the epidemic acme and the need and maximum intervention coverage was of 8-25 years.

CONCLUSIONS

OST and NEP introduction in Spanish prisons was a great advance, but the delay in their implementation and the low level of NEP coverage could have limited their potential impact on the improvement of the health of incarcerated drug users. The decline of NEP coverage in recent years is a cause of major concern for the evolution of HIV and Hepatitis C epidemics.

Depression among regular heroin users: the influence of gender

The aim of this study was to determine the prevalence of recent (last 12 months) depression in regular young heroin users and to ascertain factors associated with depression in this population, broken down by gender. A sample of 561 participants completed a cross-sectional survey. Eligibility criteria were: age 30 years or younger, and having used heroin for at least 12 days in the last 12 months and at least one day in the last 3 months. Participants were recruited outside of health-care facilities in the cities of Barcelona, Madrid and Seville by targeted sampling and chain referral methods. Depression was assessed using the World Mental Health Composite International Diagnostic Interview. The prevalence of recent depression was 22.3% (35.2% among women and 17.3% among men, p<0.001). In the multivariate analysis, the factors positively associated with recent depression in the whole sample were female gender, age 25 or less, inability to work due to health problems and high risk consumption of alcohol. Among woman, the related variables were age 25 or less, cocaine dependence in the last 12 months, and alcohol consumption in that period. Among men, employment status was the only related variable. Analysis of an overall sample without the gender breakdown may hide important differences in the factors associated with depression in men and women. Both prevention and treatment of depression should rely on specific gender analysis.

The intriguing association between prematurity and neonatal isolated submandibular suppurative sialadenitis

Submandibular suppurative sialadenitis occurring as an isolated lesion in the neonatal period is extremely rare. A case of a preterm newborn, who developed an isolated submandibular suppurative sialadenitis is described. A literature review highlighting salient points on this topic is also presented. In particular, an important role of prematurity in the etiology of this pathological condition is shown and discussed.

[Indications for selective arterial embolization in the treatment of epistaxis]

After posterior packing has failed, the treatment of choice for severe, recurrent posterior epistaxis is arterial ligature, usually through a transantral approach to the Internal Maxillary artery (LTA) or selective percutaneous embolization (EP). The advantages and disadvantages of each technique are discussed by various Authors. A critical review of the literature brings to light the discrepancies between the results of various studies: in a series by Strong et al. and in a review of the literature EP proved more effective than LTA (90-94% vs. 85-89%). On the contrary, using personal data Cullen and Tami reported that the results are analogous. As regards complications, these proved slightly more frequent, but minor, with LTA while the rare complications with EP were more serious. The per-patient costs fundamentally depend on the type of hospital management and the availability of a treatment center; the results of the various studies are not analogous in this regard. The specific indications for the choice of which technique to use include: LTA: ethmoid artery hemorrhage, severe arteriosclerosis of the carotid compartment and allergy to the contrast medium; EP: cardiovascular instability, severe anemia and all conditions which are contraindications for general anesthesia. In the cases studied by the Authors, of the total 203 patients admitted to hospital for posterior epistaxis between May 1995 and November 1999, 12 (5.9%; on the average 2.6 pt/yr) showed values lower than those found at other Centers. A total of 13 EP procedures were performed and the result was positive (stopping the hemorrhage) in 11 (91.7%). In one post-traumatic case there was a recurrence which could not be controlled by EP and thus the Authors resorted to surgical ligature. All the patients underwent fibroscopy after the posterior packing was removed and before establishing the indications for EP. A full 50% of the patients treated showed arterial hypertension and in all patients except the one with multiple traumas, the pre-embolization angiography showed the presence of submucosal teleangiectasia in the site of the epistaxis. This report supports the hypothesis that, in the presence of triggering factors (hypertension, pregnancy), untreatable epistaxis is sustained by a submucosal vascular malformation. On the other hand, it also asserts that although the patient evaluation to determine the EP treatment was less invasive than that used in other Centers, it was able to identify the patients with this malformation, thus validating the clinical criteria used.
