Introduction. Isolated cataplexy, without the presence of narcolepsy, is a relatively rare condition, and can be regarded as attacks of motor inhibition with loss of muscle tone and areflexia. The diagnosis of cataplexy relies on the clinical presentation and medical history and it is rarely confirmed by video-polygraph. We here described a female patient treated for prolactinoma who developed isolated cataplexy. Case report. A 53-year-old female treated with bromocriptine for a macroprolactinoma presented with sudden episodes of weakness and toneless legs leading to falls and injuries on several occasions. Cardiovascular evaluation was completely normal. Psychiatric evaluation showed no psychotic phenomenology or suicidal ideas. Pituitary imaging showed empty sella with a remnant sellar mass with infraand parasellar extension. Neurological examination revealed mild obstructive sleep hypopnea/apnea. Electroencephalographic monitoring during sleep and awakening did not show appearance of epi potentials. HLA haplotyping was positive for HLADR3,16;DR51;DQ1 allele, confirming a diagnosis of isolated cataplexy. Treatment included tricyclic antidepressants and reduction of bromocriptine dosage with resolution of cataplexy. Conclusion. We reported the first case of isolated cataplexy most probably associated with dopamine agonist treatment for prolactinoma. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Background: Insulin resistance (IR) assessed by the Homeostatic Model Assessment (HOMA) index in the acute phase of myocardial infarction in non-diabetic patients was recently established as an independent predictor of intrahospital mortality. In this study we postulated that acute IR is a dynamic phenomenon associated with the development of myocardial and microvascular injury and larger final infarct size in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (pPCI).Methods: In 104 consecutive patients with the first anterior STEMI without diabetes, the HOMA index was determined on the 2nd and 7th day after pPCI. Worst-lead residual ST-segment elevation (ST-E) on postprocedural ECG, coronary flow reserve (CFR) determined by transthoracic Doppler echocardiography on the 2nd day after pPCI and fixed perfusion defect on single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) determined six weeks after pPCI were analyzed according to HOMA indices.Results: IR was present in 55 % and 58 % of patients on day 2 and day 7, respectively. Incomplete post-procedural ST-E resolution was more frequent in patients with IR compared to patients without IR, both on day 2 (p = 0.001) and day 7 (p < 0.001). The HOMA index on day 7 correlated with SPECT-MPI perfusion defect (r = 0.331), whereas both HOMA indices correlated well with CFR (r = -0.331 to -0.386) (p < 0.01 for all). In multivariable backward logistic regression analysis adjusted for significant univariate predictors and potential confounding variables, IR on day 2 was an independent predictor of residual ST-E ≥ 2 mm (OR 11.70, 95% CI 2.46-55.51, p = 0.002) and CFR < 2 (OR = 5.98, 95% CI 1.88-19.03, p = 0.002), whereas IR on day 7 was an independent predictor of SPECT-MPI perfusion defect > 20% (OR 11.37, 95% CI 1.34-96.21, p = 0.026).Conclusion: IR assessed by the HOMA index during the acute phase of the first anterior STEMI in patients without diabetes treated by pPCI is independently associated with poorer myocardial reperfusion, impaired coronary microcirculatory function and potentially with larger final infarct size. © 2014 Trifunovic et al.; licensee BioMed Central Ltd.

Objectives To analyze the incidence of the overlap syndrome of depressive symptoms and delirium, risk factors, and independent and dose-response effect of the overlap syndrome on outcomes in elderly adults with hip fracture. Design Prospective cohort study. Setting University hospital. Participants Individuals with hip fracture without delirium (N = 277; aged 78.0 ± 8.2) consequently enrolled in a prospective cohort study. Measurements Depressive symptoms were assessed using the Geriatric Depression Scale and cognitive status using the Short Portable Mental Status Questionnaire upon hospital admission. Incident delirium was assessed daily during the hospital stay using the Confusion Assessment Method. Information on complications acquired in the hospital, severity of complications, re-interventions, length of hospital stay, and 1-month mortality was recorded. Results Thirty (10.8%) participants had depressive symptoms alone, 88 (31.8%) delirium alone, 60 (21.7%) overlap syndrome, and 99 (35.7%) neither condition. According to multivariate regression analysis, participants with the overlap syndrome had significantly higher incidence of vision impairment (P =.02), longer time-to-surgery (P =.03), and lower cognitive function (P <.001) than participants with no depressive symptoms and no delirium. In the adjusted regression analysis, participants with neither condition were at lower risk of complications than those with the overlap syndrome (P =.03). After adjustment, participants with the overlap syndrome were at higher risk of longer hospital stay independently (P =.003) and in a dose-response manner in the following order: no depression and no delirium, depressive symptoms alone, delirium alone, and the overlap syndrome (P =.002). Conclusion Depressive symptoms and delirium increase the likelihood of adverse outcomes after hip fracture in a step-wise manner when they coexist. To reduce the risk of adverse outcome in individuals with hip fracture, efforts to identify, prevent, and treat this condition need to be increased. © 2014, The American Geriatrics Society.

Background: We investigated the traditional and new bio- markers as predictors of cardiovascular mortality in the func- tionally disabled elderly who are living in a community. Methods: This prospective study included 253 participants (78.3% women) aged 65 and over who were monitored for 32 months. Receiver operating curve analysis and the Cox proportional hazard model were used to identify univariate and multivariate predictors of cardiovascular mortality. The Kaplan-Meier survival curve and Log rank test were used for survival analysis. Results: During the study, 43.1% participants died from car- diovascular diseases. Cutoff points of multivariate predictors were used to build a score system. The risk score was positive in patients with three or more of the following predictors: albumin <40 g/L, body mass index <25 kg/m2, total serum bilirubin <10.5 (imol/L, blood urea nitrogen >6.5 mmol/L and high-sensitivity C-reactive protein >2.25 mg/L. The rel- ative risk for cardiovascular mortality for someone with a positive vs. negative score was 3.91 (95% Cl: 2.55-5.98; P< 0.001). There was no change in risk after adjustment for age; sex, traditional cardiovascular risk factors, comorbidities and a number of disabilities. Conclusions: Presence of lo* grade inflammation, malnulri tion and early signs of renal dy sfunction are essential for car- diovascular risk among the functional disabled elderly and may be assessed using the proposed new inflammatory m3lnuhffion-renal involved score (1MRIS).

Background: Previous studies have indicated that high sensitivity C-reactive protein (hs-CRP) is a risk factor for the peripheral arterial disease (PAD) in diabetes. This study aimed to evaluate the possible predictive significance of hs- CRP for the development and progression of PAD in patients with type 2 diabetes (T2D). Mathods: The study included 80 patients previously diagnosed with T2D, aged 45-70 years, divided into group A (T2D patients with PAD; n=38) and group B (T2D patients without PAD; n=42). After five years, all the patients were re-examined and divided into subgroups depending on de novo development of PAD or progression of previously diagnosed PAD. Ankle-Brachial Index (ABI) measurement was used for PAD diagnosis and hs-CRP was determined by nephelometry. Results: We found significantly higher hs-CRP levels in group A compared to group B, but only at baseline. Among the patients in group A, those with later progression of PAD (subgroup A1) had the highest levels of hs-CRP at baseline, although not significantly different from those in subgroup A2 (non-progressors). In contrast, hs-CRP level was significantly higher in subgroup B1 (progressors) in comparison to subgroup B2 (non-progressors) at both the first and sec-ond exam. Of all the investigated metabolic parameters, hs-CRP was the only independent predictor of PAD progression (OR=0.456, 95% CI=0.267-0.7815, p=0.004). The cut-off point for hs-CRP was 2.5 mg/L (specificity 75% and sensitivity 73.3%) with the relative risk for PAD of 2.93 (95% CI=1.351-6.3629). Conclusions: Our study implies that hs-CRP can be used as a reliable predictor for the progression of PAD in patients with T2D.

Pain is a common symptom in older people. It is possible that pain is underreported in older persons due to an incorrect belief that it is an inevitable part of aging. Opioid analgesics are potent medications, with confirmed efficacy for the treatment of moderate to severe pain. These drugs are commonly used in older persons. However, there is insufficient evidence regarding safety of opioids in older patients. One of the reasons for this is the lack of randomized, controlled clinical trials. People of advanced age often have comorbidites and use other prescription drugs, as well as over-the-counter (OTC) compounds, thus making them more suceptible to the risk of interactions with opioids. Significant pharmacokinetic and pharmacodynamic changes that occur with advancing age increase the risk of adverse effects of opioids. There are also some discrepancies between guidelines, which recommend the use of lower doses of opioids in older patients, and the findings in the literature which suggest that pain is often undertreated in this age group. It seems that there are significant variations in the tolerability of different opioid analgesics in older people. Morphine, fentanyl, oxycodone, and buprenorphine are still the preferred evidence-based choices for add-on opioid therapy for these patients. However, the safety and efficacy of other opioids in older patients, especially if comorbidities and polypharmacy are present, is still questionable. This review addresses the most important aspects of the use of opioids in older persons, focusing on pharmacokinetics, pharmacodynamics, adverse effects, and interactions. © 2016 Prostran, Savic Vujovic, Vuckovic, Medic, Srebro, Divac, Stojanovic, Vujovic, Jovanovic, Jotic and Cerovac.

Serbia is a demographically old nation, with 17.4 % of its residents being aged 65 years and older in 2011. The previous two decades of turbulent history have significantly affected the demographic picture of this country, and their ramifications remain visible in Serbia's economic, political, cultural, and health spheres. Major demographic forces behind population aging in Serbia can be attributed to lower fertility rates, migrations, and declining mortality (reflecting improvements in overall health leading to a longer life expectancy). In Serbia, low fertility and migrations appear to play major roles, although the relative contribution of recent migrations cannot be measured with accuracy. Patterns of demographic aging vary considerably across different geographic, socioeconomic, and cultural settings. The common denominator throughout present day Serbia is extensive political and economic transition. One would expect that, given sufficient time, this process will result in improved population health, and yet, at this stage outcomes of major health care reform in Serbia are somewhat perplexing. For the second consecutive year, Serbia’s health care system has been ranked at the very bottom of the scale among 34 European countries. It is then no surprise that the elderly represent particularly vulnerable population segment. This paper discusses some of the issues relevant to these demographic patterns of aging and aged care in contemporary Serbia, focusing on the period after 2000. © 2015, Springer Science+Business Media New York.
