The Role of a Clinical Pharmacist in the Identification of Potentially Inadequate Drugs Prescribed to the Geriatric Population in Low-Resource Settings Using the Beers Criteria: A Pilot Study.

Population aging is a global phenomenon. Each country in the world faces an increased number of older persons in the total population. With aging, a high prevalence of multiple chronic diseases occurs, leading to the use of complex therapeutic regimens and often to polypharmacy. Potentially inappropriate medication (PIM) is a medicine prescribed to a patient for whom the risks outweigh the benefits. Today, several tools are used to evaluate the use of pharmacotherapy in older adults, one of them is the 2019 AGS Beers Criteria. In this prospective, pilot study, we aimed to investigate if the number of PIMs in elderly patients would be significantly reduced if a clinical pharmacist performed a pharmacotherapy review. The study included 66 patients over 65 years of age who were hospitalized at the 1200-bed university hospital. The intervention was conducted by a clinical pharmacist who reviewed the patients' pharmacotherapy and provided written suggestions to physicians. The pharmacotherapy was again reviewed at the patients' discharge from the hospital. A total number of 204 PIMs were identified in the pharmacotherapy of the study population. At discharge, the number of PIMs decreased to 67. A total of 67% of the pharmacist's suggestions were accepted by the physicians. The pharmacist's intervention led to significant decrease in the number of PIMs on patients' discharge letters.

The role of high-income countries in the establishment and development of modern critical care in low resource settings: A Slovenian model.

BACKGROUND: Critical care medicine is a young branch of medicine, of which the development was much faster in High Income Countries (HICs) than in Low Resources Settings (LRS). Slovenia, as one of the successor states of former Yugoslavia, passed the process of transition and joined the European Union successfully. On the contrary, Bosnia and Herzegovina (B&H) went through the extremely difficult process of transition (four years of civil war), which left a deep scar to the healthcare system, including critical care medicine. OBJECTIVE: To examine the impact of HICs on the development of critical care in LRS. METHOD: This review examined the process of growing up the first modern Medical Intensive Care Unit (MICU) in the Republic of Srpska. RESULTS: The five-year process of transferring critical care knowledge from Slovenia to the health care system of Republic of Srpska has contributed to the existence of modern and state of the art MICU with tremendous social effects. CONCLUSION: The model of using the impact of HICs for improving critical care in LRS can be extrapolated to other similar settings.

Boosting ICU capacity during the COVID-19 pandemic in the western Balkan region, The Republic of Srpska experience.

Background: Response to the outbreak of poliomyelitis in mid-1950 led to recognition and consequent development of critical care. Seventy years later the humankind was struck by COVID-19, another major challenge for critical care medicine which was especially big in Low-Resources-Settings where more than two thirds of the world population live, including the population of the Republic of Srpska (RS). Design and methods: The main aim was to show an overview of all interventions in order to boost hospitals' capacities to the level which is sufficient to manage high amount of critically ill COVID-19 patients in the RS. A before-after cohort study design was conducted to evaluate the effects of interventions for increase in preparedness and capacity of ICUs for admission and treatment of COVID-19 critically ill patients in nine hospitals in the RS. Results: Following interventions, the biggest and university affiliated hospital in the RS has increased ICU capacities: total number of ICU beds increased by 38% and number of ventilators by 114%. Availability of machines for veno-venous extracorporeal membrane oxygenation (vvECMO) increased by 100%. Number of doctors who were involved in treatment of critically ill patients increased by 47% and nurse/patient's ratio reached 1:2.5. Similarly, all other hospitals experienced boosting of ICU beds by 189% and ventilators by 373% while number of doctors increased by 108% and nurse/patient's ratio reached 1:4. Conclusion: All interventions implemented during COVID-19 pandemic outbreak in the RS resulted in increasing capacity for treatment of critically ill patients, but the education of health care professionals was identified as the most important conducted intervention.

Dynamic changes in coagulation, hematological and biochemical parameters as predictors of mortality in critically ill COVID-19 patients: A prospective observational study.

INTRODUCTION: This study was created to analyze dynamic alterations in coagulation, hematological and biochemical parameters and their association with mortality of COVID-19 patients. To identify the most sensitive biomarkers as predictors of mortality more research is required. METHODS: The present study was a prospective, one-year-long observational study conducted on all critically ill, COVID-19 patients with respiratory failure. The following data were collected: demographic and clinical characteristics of the study population, comorbidities, coagulation, biochemical and hematological parameters. The primary outcome was the proportion of patients who died. RESULTS: 91 patients with median age 60 (50-67), 76.9% male, met the acute respiratory distress syndrome criteria. It was tested whether dynamic change (delta-Δ) of parameters that were found to be predictors of mortality is independently associated with poor outcome. Adjusted (multivariate) analysis was used, where tested parameters were corrected for basic and clinical patients characteristics. The only inflammatory parameter which dynamic change had statistically significant odds ratio was ΔCRP (p < 0.005), while among coagulation parameters statistically significant OR was found for Δ fibrinogen (p < 0.005) in predicting mortality. CONCLUSION: Monitoring of coagulation, hematological and biochemical parameters abnormalities and their dynamical changes can potentially improve management and predict mortality in critically ill COVID -19 patients.

Characteristics and Outcomes of Critically Ill Pregnant/Postpartum Women with COVID-19 Pneumonia in Western Balkans, The Republic of Srpska Report.

Background and Objectives: Coronavirus disease 2019 (COVID-19) is a novel infectious disease that has spread worldwide. As of 5 March 2020, the COVID-19 pandemic has resulted in approximately 111,767 cases and 6338 deaths in the Republic of Srpska and 375,554 cases and 15,718 deaths in Bosnia and Herzegovina. Our objective in the present study was to determine the characteristics and outcomes of critically ill pregnant/postpartum women with COVID-19 in the Republic of Srpska. Materials and Methods: The retrospective observational study of prospectively collected data included all critically ill pregnant/postpartum women with COVID-19 in a university-affiliated hospital between 1 April 2020 and 1 April 2022. Infection was confirmed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) from nasopharyngeal swab specimens and respiratory secretions. Patients' demographics, clinical and laboratory data, pharmacotherapy, and neonatal outcomes were analysed. Results: Out of the 153 registered pregnant women with COVID-19 treated at the gynaecology department of the University Clinical Centre of the Republic of Srpska, 19 (12.41%) critically ill pregnant/postpartum women (median age of 36 (IQR, 29-38) years) were admitted to the medical intensive care unit (MICU). The mortality rate was 21.05% (four patients) during the study period. Of all patients (19), 14 gave birth (73.68%), and 4 (21.05%) were treated with veno-venous extracorporeal membrane oxygenation (vvECMO). Conclusions: Fourteen infants were born prematurely and none of them died during hospitalisation. A high mortality rate was detected among the critically ill pregnant/postpartum patients treated with mechanical ventilation and vvECMO in the MICU. The preterm birth rate was high in patients who required a higher level of life support (vvECMO and ventilatory support).

Successful Outcomes of Critically Ill Patients with Extreme Metabolic Acidosis Treated with Structured Approach: Case Series.

INTRODUCTION: Hydrogen ion concentration which is expressed as pH value is in human blood maintained in narrow physiological range (7.36-7.44 in arterial blood). This range is crucial for normal functioning of most biochemical reactions. Extreme acidosis with pH < 6.8 is incompatible with life, unless pathophysiologic process is rapidly reversed. Timely, standardized, and structured approach to assessment and management of extreme critical illness is essential to maximize the chances of patient's survival. CASES: We present a series of 3 critically ill patients admitted to Medical intensive care unit (MICU) diagnosed with extreme metabolic acidosis (pH ⩽ 6.8). Each patient was treated using Checklist for Early Recognition and Treatment of Acute Illness and INjury (CERTAIN) which is a standard decision support tool in our MICU. Causes of extreme metabolic acidosis included hemorrhagic shock, sepsis, and acute renal failure and diabetic ketoacidosis. Rapid assessment, prompt resuscitation (IV fluids, vasopressors, mechanical ventilation, and renal replacement), and application of specific causal treatment led to positive outcomes in all 3 patients. DISCUSSION: Medical physiology textbooks set the lower limit of pH value at which life is possible to 6.8. However, examples from clinical practice show that if adequate resuscitation measures are taken early in the acute phase of the disease, the biochemical cascade of reactions that are considered irreversible (at pH ⩽ 6.8) may be reversed after all. CONCLUSION: Critical care approach to extreme metabolic acidosis is a prime example of applied clinical physiology where basic science and clinical practice connect. With these case series we show that timely and structured approach to critical illness shifts the boundaries of reversibility for some of the most severe physiologic derangements.

Assessment of Autonomic Nervous System Dysfunction in the Early Phase of Infection With SARS-CoV-2 Virus.

BACKGROUND: We are facing the outburst of coronavirus disease 2019 (COVID-19) defined as a serious, multisystem, disorder, including various neurological manifestations in its presentation. So far, autonomic dysfunction (AD) has not been reported in patients with COVID-19 infection. AIM: Assessment of AD in the early phase of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus). PATIENTS AND METHODS: We analyzed 116 PCR positive COVID-19 patients. After the exclusion of 41 patients with associate diseases (CADG), partitioned to patients with diabetes mellitus, hypertension, and syncope, the remaining patients were included into a severe group (45 patients with confirmed interstitial pneumonia) and mild group (30 patients). Basic cardiovascular autonomic reflex tests (CART) were performed, followed by beat-to-beat heart rate variability (HRV) and systolic and diastolic blood pressure variability (BPV) analysis, along with baroreceptor sensitivity (BRS). Non-linear analysis of HRV was provided by Poincare Plot. Results were compared to 77 sex and age-matched controls. RESULTS: AD (sympathetic, parasympathetic, or both) in our study has been revealed in 51.5% of severe, 78.0% of mild COVID-19 patients, and the difference compared to healthy controls was significant (p = 0.018). Orthostatic hypotension has been established in 33.0% COVID-19 patients compared to 2.6% controls (p = 0.001). Most of the spectral parameters of HRV and BPV confirmed AD, most prominent in the severe COVID-19 group. BRS was significantly lower in all patients (severe, mild, CADG), indicating significant sudden cardiac death risk. CONCLUSION: Cardiovascular autonomic neuropathy should be taken into account in COVID-19 patients' assessment. It can be an explanation for a variety of registered manifestations, enabling a comprehensive diagnostic approach and further treatment.

Serum levels of nitric oxide and endothelin-1 in vasculopathy managed with hyperbaric oxygen therapy.

Roles of nitric oxide (NO) and endothelin-1 (ET-1) in the local regulation of blood flow under physiological conditions are important and well known, while data on their effects and interactions in conditions of hyperbaric hyperoxia is still insufficient. This was a prospective observational study which included patients who underwent hyperbaric oxygen therapy (HBOT) in accordance with existing therapeutic protocol for peripherial arterial disease (PAD) during time period of six months, between january and july of 2016. Clinical stage of PAD according to Fontain was taken into account, as well as risk factors, demographic, anthropometric and clinical characteristics of studied patients. The study included 64 patients with a mean age (±Sd) 60.2±12.7 years, of whom 28 were female. Patients' NO serum levels in all observed categories before and after HBOT were not signifficantly different, except for stage II PAD (NObefore HBOT 21.9±9.6 vs. NOafter HBOT 26.2±12.1 (p = 0.04)). On the contrary, in all studied patients ET-1 level increased signifficantly after HBOT (ET-1before HBOT 4.2±11.6 vs. ET-1after 18.3±21.0 (p < 0.001)). Treatment of PAD using HBOT leads to the predominance of vasoconstrictor effects probably caused by elevation of serum ET-1 concentrations, while other factors such as exposure time to hyperbaric conditions, activation of antioxidant molecules, and the influx of other interfering substances must be considered in interpreting the effects of NO molecules.

Multiple organ dysfunction caused by a foreign body in the esophagus. / Disfunção de múltiplos órgãos causada por corpo estranho no esôfago.

We present the case of a 71-year-old patient who was admitted to the medical intensive care unit in a state of multiple organ dysfunction. After the fourth day of applying all needed life-saving measures (vasopressor stimulation, mechanical ventilation, continuous dialysis treatment, broad spectrum antibiotic therapy, and other supportive measures), nonspecific heteroanamnestic data revealed that the patient had been having a persistent difficulty in swallowing liquids and food for a few days prior to hospital admission. After performing additional radiological and endoscopic diagnostic procedures, a foreign body was detected; a steel wire that had a length of approximately 6cm and was bent in a half had penetrated the esophagus and was projected into the seventh neckline. We managed to evacuate the foreign body endoscopically without further complications, and we stabilized our patient using additional therapeutic measures as needed.

Apresentamos o caso de uma paciente de 71 anos de idade admitida à unidade de terapia intensiva clínica em condição de falência de múltiplos órgãos. Após o quarto dia, com aplicação de todas as modalidades de suporte à vida (estímulo com vasopressores, ventilação mecânica, terapia com diálise contínua, terapia com antibióticos de amplo espectro e outras medidas de suporte), dados inespecíficos fornecidos por acompanhante revelaram que a paciente vinha apresentando dificuldade persistente para deglutir líquidos e alimentos sólidos por alguns dias antes da admissão ao hospital. Após a realização de procedimentos adicionais de diagnóstico radiológico e endoscópico, detectou-se a presença de um corpo estranho no esôfago: um fragmento de fio de aço com cerca de 6 cm de comprimento e dobrado ao meio, que havia penetrado a parede do esôfago e se projetava ao nível da sétima vértebra cervical. Conseguimos remover o corpo estranho por via endoscópica sem maiores complicações e, a seguir, estabilizar nossa paciente, com utilização de medidas terapêuticas adicionais, conforme necessário.

Ventriculitis Caused by Multidrug-Resistant Bacteria in a Medical Intensive Care Unit with Limited Resources.

The widespread use of various devices in the diagnosis or treatment of critically ill neurological patients has led to the more frequent appearance of a new group of meningitis and ventriculitis caused by resistant Gram-negative bacteria or staphylococci. In literature, it has been labeled as health care-associated meningitis and ventriculitis. In our clinical practice (in resource-limited countries), we still have any viable experience neither in the application of these diagnostic and therapeutic tools nor in the handling of complications resulting from their use. However, we have had positive results with the help of the existing guidelines and advice from colleagues in the region (through a video consultation model) while also respecting other factors that reflect our work environment.

[Neurophysiological evaluation of patients with degenerative diseases of the cervical spine].

BACKGROUND/AIM: Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography) aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalities. Considering diversities of clinical outcomes for these patients, complex diagnostic evaluation provides a prognosis of the disease progression. METHODS. The study included 21 patients (48.24 +/- 11.01 years of age) with clinical presentation of cervical spondylarthropathy, without neuroradiological signs of myelopathy. For each patient, in addition to conventional neurophysiological tests (somatisensory evoked potentials--SSEP, motor evoked potentials--MEP, electromyoneurography--EMG, nerve conduction studies), we calculated central motor conduction time (CMCT(F)), as well the same parameter in relation to a different position of the head (maximal anteflexion and retroflexion), so-called dynamic tests. RESULTS: Abnormalities of the peripheral motor neurone by conventional EMNeG was established in 2/3 of the patients, correponding to the findings of root condution time. Prolonged conventional CVMP(F) were found in 29% of the patients, comparing to 43% CVMP(F) abnormalities found with the dynamic tests. In addition, the SSEP findings were abnormal in 38% of the patients with degenerative diseases of the cervical spine. CONCLUSION: An extended neurophysiological protocol of testing corticospinal functions, including dynamic tests of central and periheral motor neurons are relevant for detection of subclinical forms of cervical spondylothic myelopathy, even at early stages. In addition to the conventional neurophysiological tests, we found useful to include the dynamic motor tests and root conduction time measurement in diagnostic evaluation.
