OBJECTIVE: The objective of this study was to estimate the secondary attack rate in unvaccinated members of households of two regions in the Slovak Republic for the period November 2020 ‒ April 2021. INTRODUCTION: SARS-CoV-2 infection poses a high risk of transmission in close-contact indoor settings, such as households. The household transmissibility of SARS-CoV-2 varies widely across countries. METHODS: We included 278 households for SARS-CoV-2 transmission analysis. We calculated the secondary attack rate (SAR). We assessed sex, level of disease severity and means of isolation during infection of index cases as determinants of disease transmissibilityRESULTS: The secondary attack rate in 278 households was estimated at 63.7% (95%CI: 58.2‒66.7%). The SARs were different by sex (60.2% in females, 67.5% in males). The highest SAR was observed in the households of asymptomatic cases (77.8%), followed by moderate severity (66.5%), hospital admissions (63.2%) and mild disease (58.2%). CONCLUSION: We found a high household secondary attack rate in two regions of Slovakia in the period when Alpha variant (B.1.1.7) of SARS-CoV-2 was dominant in the country. The results highlight the importance of monitoring transmission dynamics (Tab. 1, Fig. 1, Ref. 12). Text in PDF www.elis.sk Keywords: COVID-19, secondary attack rate, Slovak Republic, households.

OBJECTIVE: To investigate the relationship of sarcopenia with systemic inflammation response index (SIRI), monocyte to high-density lipoprotein ratio (MHR) and platelet parameters in geriatric patients. METHODS: We designed a cross-sectional retrospective study in patients presented to a geriatric outpatient clinic for the first time. The diagnosis of sarcopenia was made in accordance with the EWGSOP2 criteria. SIRI, MHR, mean platelet volume /Platelet count (MPV/Plt), platelet distribution width /Platelet (PDW/Plt), platelet/lymphocyte ratio (PLR) were calculated from fasting blood test results at the time of admission. RESULTS: Among 262 patients, 79 patients (30.1%) with sarcopenia had significantly higher frequencies of delirium, hypothyroidism, chronic kidney disease and probable depression (p=0.010; p=0.018; p=0.034; p<0.001). Malnutrition scores and cognitive impairment scores were significantly lower in sarcopenic group (p<0.001 for both). Patients with sarcopenia had significantly higher MHR, SIRI and C-reactive protein values than patients without sarcopenia (p<0.001; p=0.001 and p=0.006, respectively). No significant difference was found between the groups in terms of MPV/Plt, PDW/Plt, PLR (p=0.605; p=0.920; p=0.510). Area under the curve for MHR was 0.675 (95% CI: 0.604-0.746, p0.99. CONCLUSIONS: The finding of higher MHR and SIRI in geriatric sarcopenia patients supports low-grade chronic inflammation in the pathophysiology of sarcopenia. These non-invasive, cost-effective and simple parameters based on traditional peripheral blood cell counts may be warning signs for sarcopenia in the geriatric population (Tab. 3, Fig. 1, Ref. 25).

BACKGROUND: Hypertension is a leading cause of cardiovascular disease. This review examines the literature on hypertension control in the Czech Republic from 1972 to 2022 addressing limited data on its effectiveness. METHODS: A literature review was conducted covering the period from 1972 to 2022, utilizing MEDLINE (PubMed), Web of Science, and Scopus databases. Articles were selected based on title and abstract evaluations, with full-text reviews performed as needed. Thirteen studies involving 44,990 participants were included in this review. RESULTS: Control rates increased from 2.8% (men) and 5.2% (women) in 1985 to 32.3% (men) and 37.4% (women) from 2015 to 2018. Women showed better blood pressure control. Specialised centres achieved higher success (48%) than general practitioners (18.4%). Diabetic patients had a lower percentage (29.1%) of patients meeting their target values (<130/80 mmHg) compared to non-diabetic patients, who had a higher percentage (60.6%) meeting their target values (<140/90 mmHg). CONCLUSION: Hypertension treatment success rate in the Czech Republic improved significantly over the last 50 years and is currently comparable to that of other European countries with similar healthcare resources. However, it still remains suboptimal and lags behind the countries with the most successful treatment outcomes (Tab. 3, Fig. 1, Ref. 37).

OBJECTIVES: to investigate the difference in serum tryptase levels between post-acute COVID-19 syndrome (PACS) patients and controls. BACKGROUND: PACS has been defined as symptoms that persist for more than 3 months after the onset of COVID-19. The pathogenesis is still unknown, but mast cell activation has been proposed as one of the mechanisms, and increased serum tryptase levels have been demonstrated in PACS patients. METHODS: A total number of 133 patients were included: 50 with PACS, 37 asymptomatic COVID-19 convalescents, and 46 controls with a negative history of COVID-19. Serum tryptase levels were determined in all participants. RESULTS: There was no significant difference in serum levels of tryptase among the groups. CONCLUSION: the role of mast cell activation in PACS remains unclear and further research is needed to fill the gaps in understanding the pathogenesis of this complex and heterogeneous disorder (Tab. 2, Ref. 17).

OBJECTIVES: In this study, we analyzed pTa bladder cancer (BC) for molecular markers BCL2, TP53, FOXA1, and GATA3 in relation to cancer recurrence. METHODS: We analyzed samples of 79 patients with the pTa stage of BC using a real-time polymerase chain reaction (real-time PCR) between September 2018 and September 2020. The expression levels of BCL2, TP53, FOXA1, and GATA3 were compared with homologous non-tumor bladder tissue. RESULTS: Expression of FOXA1, GATA3, and TP53 was significantly higher (p<0.01) in NMIBC samples compared to homologous non-tumor tissue. The expression of TP53 and FOXA1 in pTa was significantly lower (p<0.01) in the high-grade (HG) tumor when compared to the low-grade (LG) tumor. In contrast, the relative quantification (RQ) of GATA3 was significantly higher (p<0.01) in HG pTa. Patients with recurrence (pTa=33) had significantly higher expression of TP53, and GATA3 (p<0.01), and the gene of FOXA1 (p<0.01) had a significantly lower expression when compared to pTa tumors without recurrence. The expression of Bcl-2 was not statistically significant. CONCLUSION: Our results, indicate, that comparing expression levels of these genes in cancer and cancer-free tissue could provide valuable data, as patients with pTa BC recurrence within up to 54 months of follow-up had a significantly higher RQ of TP53, GATA3, and FOXA1 when compared to pTa BC patients without recurrence (Tab. 2, Fig. 8, Ref. 54).

BACKGROUND: Patient's age is considered to be one of the most relevant factors in selecting surgical candidates for decompressive hemicraniectomy after malignant hemispheric infarction. However, questions about surgical indication in older patients, patients with consciousness disorder or patients with large infarctions remain unanswered. OBJECTIVE: Our aim was to design a multifactorial scoring scale based on a combination of patient-specific factors in order to optimize the assessment of prognosis in patients after hemicraniectomy malignant strokes. METHODS: In this prospective observational study with a one-year follow-up, we assessed clinical and imaging data of patients who underwent decompressive hemicraniectomy due to malignant brain infarction. Barthel index was used as a single outcome measure to distinguish favorable vs. unfavorable outcomes. Associations between multiple variables and clinical outcome were assessed. Subsequently, a design of a predictive scoring system was proposed. RESULTS: Age of the patient, preoperative level of consciousness, midline shift, and volume of infarction showed a significant association with postoperative Barthel index. According to the identified factors, a multifactorial prognostic scoring system was introduced, aimed to distinguish between favorable and unfavorable outcomes. Using ROC analysis, it has achieved an AUC of 0.74 (95%CI 0.58‒0.89, p=0.01)CONCLUSIONS: Prediction of postoperative outcome should be based on multiple variables. Our scale, based on the clinical and imaging data, can be used during decision-making to estimate potential benefit of decompressive craniectomy in patients after malignant brain infarction (Tab. 5, Fig. 1, Ref. 32).

BACKGROUND: Clinical assessment and laboratory markers provide valuable information on tissue perfusion and enhance the optimalisation of management in the treatment of patients on extracorporeal membrane oxygenation (ECMO). The PCO2 gap is a reliable marker of cardiac output (CO) and perfusion. The aim of this study was to evaluate the PCO2 gap as a marker of tissue hypoperfusion and to compare it to lactate and SvO2. METHODS: A single-center retrospective study on 131 adult cardiac patients who underwent ECMO implantation in the period between 2010 and 2021. Baseline characteristics, laboratory markers and mortality were analyzed. RESULTS: There was a statistically significant difference in the plasmatic levels of lactate, SvO2 and PCO2 gap between patients that survived and those who died post ECMO implantation (3.6±3.29 vs 7.15±7.38 mmol/l, p<0.001; 69.13±9 vs 67.38±10%, p<0.001; 7.65±2.93 vs 8.34±3.71, p<0.001 respectively). There was a statistically significant difference in PCO2 gap in the first 5 arterial blood gas (ABG) samples post ECMO implantation between patients that survived and those who died (9.08±4.79 vs 10.37±5.35, p<0.003). For SvO2, this difference was not statistically significant (69.82±11.91 vs 68.51±11.72, p<0.104). There was a statistically significant but low negative correlation between SvO2 and PCO2 gap post ECMO implantation (r = ‒0.354, p<0.001). CONCLUSION: The PCO2 gap is a valuable biomarker for monitoring tissue perfusion in patients on ECMO. It is associated with increased mortality and should be an integral part of clinical evaluation.

Cardio-cerebral infarction (CCI) is a term coined to describe concomitant myocardial infarction and acute ischemic stroke. Acute myocardial infarction and stroke, as separate events, constitute some of the most important causes for disability and mortality in aging societies. Stroke can either occur simultaneously with myocardial infarction or become a serious complication of myocardial infarction and/or its treatment. The frequency of CCI has been reported at a 0.009% incidence rate in stroke patients and is associated with an extremely high mortality. Because of the rare occurrence of CCI, there are currently no guidelines for assessing its diagnosis and optimal treatment. Therefore, currently, the management of CCI cases needs to be individualized. Hopefully, in the future, the results of large clinical trials or prospective registries are expected to enhance our understanding of managing concomitant acute MI and stroke. In this review we have focused on the current literacy in the diagnosis and treatment of CCIs. The paper illustrates potential distinct scenarios of CCI through the analysis of three patient cases (Fig. 5, Ref. 65).

AIM: We aimed to investigate the possible cardioprotective effects of paricalcitol (PR), its vitamin D receptor agonist, and vitamin D3 (VIT-D3) on an experimental model of doxorubicin (DX) cardiotoxicity by 99mTc-PYP scintigraphy, electrocardiographic (ECG) and biochemical methods. METHOD: Forty-two male Wistar/Albino rats (250‒300 g; aged 10‒12 weeks) were randomly separated into six groups, namely into control (CN), doxorubicin (DX), paricalcitol (PR), vitamin D3 (VIT-D3), paricalcitol + doxorubicin (PR+DX), and vitamin D3 + doxorubicin (VIT-D3+DX) groups. Cardiotoxicity was induced by three doses of DX (18 mg/kg, i.p.) at 24-hour intervals on days 18, 19 and 20. PR (0.5 ug/ kg, i.p) and VIT-D3 (5,000 IU/kg, i.p) were injected for 20 days before and after the application of DX (18 mg/kg, i.p.). On day 21 of the experiment, biochemical parameters [tumor necrosis factor TNF-alpha (TNF-α); interleukin-6 (IL-6), nitric oxide (NO), and cardiac troponin T (cTnT)], as well as ECG and scintigraphic (99mTc-PYP) features were assessed. RESULTS: Compared to CN, DX significantly raised TNF-α, IL-6, and NO in heart tissue, cTnT in serum, 99mTc-PYP uptake in the myocardium, and ECG parameters, specifically QRS complex duration, QT interval duration, and ST-segment amplitude, while also reducing heart rate (p<0.001). Pretreatment with PR and VIT-D3 mitigated these abnormalities produced by DX in the heart (p<0.001). CONCLUSION: Results show that vitamin D receptor agonist paricalcitol and vitamin D protect against DX-induced cardiotoxicity through anti-inflammatory and antioxidant effects (Fig. 4, Ref. 59).

C4d, a split product of C4 activation in classical and lectin pathways of the complement system activation, has been regarded as a footprint of tissue damage in antibody-mediated rejection in transplantology. The introduction of C4d staining into daily clinical practice aroused an ever-increasing interest in the role of antibody-mediated mechanisms in kidney allograft rejection. However, this marker of complement activation is also important in other various kidney glomerular pathologies such as immunoglobulin A nephropathy, membranoproliferative glomerulonephritis, lupus nephritis, and others. In routine histopathological practice, C4d staining can be done by two histological methods, specifically by immunofluorescence on frozen tissue using monoclonal antibody to C4d (with the downside of unsteady availability of frozen tissue) or by immunohistochemistry using C4d antibodies on formalin-fixed and paraffin-embedded renal tissue. The aim of this narrative review is to summarize recent knowledge about the complement fragment C4d and its significance in different kidney pathologies, focusing on its immunohistochemical detection in renal tissue biopsies. We have supplemented this review with our experience with our proprietary methodology of preparation and practical use of antibodies such as anti-C4d, on a small national level. Immunohistochemical staining for C4d has revolutionized the field of renal histopathology. Despite being a simple diagnostic test, its utility can be of utmost importance, especially in a resource-poor setting where immunofluorescence and frozen tissue may not be available (Fig. 2, Ref. 53). Keywords: C4d deposition, immunohistochemistry, kidney glomerular diseases, kidney transplant, renal tubular damage.

Medication adherence is crucial for optimal treatment outcomes, yet many patients struggle to follow their prescribed regimens, impacting patients, families, and healthcare systems. Measurement of adherence is vital for effective care planning and intervention. This review explores medication adherence challenges and measurement methods, including therapeutic drug monitoring (TDM), medication event monitoring system (MEMS), analysis of adherence in insurance/pharmacy database, pill counts, and self-reports, each with its advantages and limitations.This review advocates a partnership-based approach to adherence, stressing standardized reporting and team-based care. Adherence is influenced by many factors such as complex regimens, packaging, patient perspectives, side effects. Effectively addressing these factors is crucial for improving patient outcomes. In summary, medication adherence is vital but complex. The article covers various adherence measurement methods to promote medication adherence as an important matter (Tab. 5, Fig. 2, Ref. 91).

Conn's syndrome, defined as unilateral aldosterone-producing adenoma, accounts for 35-40% of cases of primary hyperaldosteronism. Primary hyperaldosteronism typically occurs in younger patients with poorly controlled arterial hypertension due to extracellular fluid retention, in whom at least a triple combination of antihypertensives, including a diuretic, is needed to maintain normotension. The clinical picture of arterial hypertension may be complemented by symptoms associated with hypokalaemia, such as weakness, fatigue, palpitations, convulsions, polydipsia, or polyuria. In addition to arterial hypertension and hypokalaemia, the diagnosis of Conn's syndrome relies on examination of serum renin and aldosterone concentrations, plasma renin activity, exercise or furosemide stimulation tests, and imaging studies, preferably computed tomography. The method of treatment of Conn's syndrome is adrenalectomy. In patients with primary hyperaldosteronism with underlying bilateral adrenal cortical hyperplasia or patients contraindicated for surgery, mineralocorticoid receptor antagonists are administered in combination with antihypertensives targeted for optimal blood pressure control.In the group of patients after kidney transplantation, the exact incidence of primary hyperaldosteronism is unknown. Based on a cross-sectional study performed in 2020, it is estimated to be approximately 15% in the group of patients with unsatisfactorily compensated arterial hypertension; in the cohort of normotensive recipients, the incidence of primary hyperaldosteronism is not documented. Diagnosis of Conn's syndrome in patients in the early period after kidney transplantation is problematic, as the prevalence of arterial hypertension in transplanted patients is high (70-90%) according to the literature. Mineral abnormalities, including hypokalaemia, are also common in the early post-transplant period, mainly due to factors such as duration of cold ischaemia, onset of graft function, donor parameters, post-transplant tubulopathy, and diuretics, the effects of immunosuppressive drugs (especially calcineurin inhibitors and corticosteroids), and possibly potassium-restricted dietary habits that the patient brings from the pre-transplant period, which may mask the effect of hyperaldosteronism on potassium.We present the case of a patient who was diagnosed with Conn's syndrome 7 months after primary kidney transplantation from a deceased donor based on persistent hypokalaemia unresponsive to replacement therapy. At the time of the first manifestation of severe hypokalaemia, the patient was treated with a dual combination of antihypertensives (amlodipine at a daily dose of 5 mg and carvedilol at a daily dose of 50 mg), without the need for a diuretics.We consider the case interesting because the spectrum of mineral and acid-base abnormalities in advanced renal failure and in the early post-transplant period, as well as acid-base and mineral imbalances, including hypokalaemia, and the high prevalence of arterial hypertension in the post-transplant period, may mask the picture of Conn's syndrome (Fig. 3, Ref. 19).

Insulin resistance (IR) is the most significant risk factor for post-transplant diabetes mellitus (PTDM). This study aimed to determine the effects of regular physical activity on IR and PTDM in patients after kidney transplantation (KT). The study group (n = 22) participated in aerobic or combined sports (aerobic and anaerobic). Monitoring was provided by a sports tracker (Xiaomi Mi Band 4, compatible with the Mi Fit mobile application). Waist circumference was significantly lower (p = 0.0437, p = 0.0372), graft function was better (p = 0.0036, p = 0.0137), fasting blood glucose was lower (p = 0.0016, p = 0.0003), C-peptide level was lower (p = 0.0447, p = 0014) in the 3rd and 6th months of monitoring, and low-density lipoprotein was lower at 6 months (p = 0.0444) in the observed group than in the control group. IR was significantly lower at 6 months (p = 0.0202), and fasting blood glucose was significantly lower at 3 and 6 months (p = 0.0227) in the observed group. We confirmed the significant effect of regular physical activity on preventing the development of IR and impaired fasting glucose levels in patients after KT (Tab. 1, Fig. 4, Ref. 27).

BACKGROUND: Several studies have investigated independently of clinical education, it has been emphasized that students experience fear, anxiety, sadness and uncertainty during the pandemic. AIM: This study aimed to investigate the effect of fear of COVID-19 on the level of anxiety and self-confidence of midwifery students who did their clinical internship during the pandemic. METHODS: Convenience sampling yielded 181 senior midwifery students who had experienced clinical internships during the COVID-19 pandemic. Two state universities conducted an online cross-sectional predictive study from February to June 2021. Data were collected by an Information Form, the COVID-19 Fear Scale, the State-Trait Anxiety Inventory, and the Self-Confidence Scale. RESULTS: The study findings were that the students' fear of COVID-19 (16.72 ± 4.89), state anxiety (52.65 ± 8.41), and trait anxiety (48.66 ± 6.80) were above average, and their self-confidence was moderate. The result indicated that midwifery students' fear of COVID-19 increased, their state anxiety increased (p < 0.01), and their self-confidence decreased (p < 0.01). Fear of COVID-19 accounted for 47% of state anxiety, 6% of trait anxiety, and 22% of self-confidence. CONCLUSION: The level of COVID-19 fear of midwifery students who did clinical internships during the pandemic negatively affected their anxiety and self-confidence levels (Tab. 4, Ref. 34).

NTRODUCTION: Distal pancreatectomy is a standard surgical procedure for selected benign, premalignant, and malignant lesions localized in the pancreatic body or tail. Surgical resection remains the only curative option for patients diagnosed with adenocarcinoma of the pancreas. PATIENTS AND METHODS: Perioperative and postoperative clinical courses were retrospectively assessed in patients, who underwent distal pancreatectomy during the 2011‒2021 period. RESULTS: During the 2011‒2021 period, a total of 112 distal pancreatectomies were performed. 67 patients (59.8%) underwent laparoscopic distal pancreatectomy, and 45 patients (40.2%) open laparotomy. The conversion was necessary for 13 patients (11.6%). Distal pancreatectomies performed laparoscopically were associated more often with biochemical leak and the development of grade B fistula, on the other hand grade C fistula developed only in patients operated by open laparotomy (LPT). The mean operating time was slightly longer in the laparoscopic group (227.1 min vs 214.6 min). The mean estimated blood loss was significantly higher in the LPT group (540.4 ml vs 191.9 ml). The mean hospitalization time was slightly longer in the LPT group (11.8 days vs 9.3 days). The rates of early reoperations were comparable between both groups (6 vs 5). CONCLUSION: Laparoscopic techniques are preferred in centers around the world to bring patients benefits by using a minimally invasive approach. These techniques are also preferred in our center, in nearly 60% of all distal pancreatectomies performed during 10 years, but on the other hand, there is a much more careful approach chosen in cases of malignant disease to achieve adequate radicality (Tab.4, Ref. 20).

BACKGROUND: In this study, we aimed to examine the telomerase activity and hTERT gene expression in patients with acute coronary syndrome (ACS) and those with stable coronary artery disease (SCAD) and compare the results to controls. Additionally, we compared overall mortality rates relative to the telomerase activity. METHODS: A total of 211 patients (78 ACS and 71 SCAD patients) were included in the study. The telomerase concentration was measured by ELISA and used to determine telomerase activity. The hTERT gene expression was determined by real-time PCR. RESULTS: The serum telomerase enzyme concentration was lower in ACS (36.61 ± 1.54) and SCAD (36.79 ± 1.57) when compared to the control group (37.03 ± 2.25). However, this difference did not reach statistical significance (p = 0.890). The hTERT gene expression acting in telomerase enzyme synthesis was 2.7-fold lower in ACS group (p = 0.070) and 2.2-fold lower in the SCAD group (p = 0.101) compared to the control group. Patients were followed for a median of 32 months (minimum: 0.1, maximum: 46.8). The serum telomerase concentrations in patients who died and those survived in the SCAD group (35.98 ± 2.02 vs 36.86 ± 1.52 ng/ml, respectively; p = 0.529) were similar to those in the ACS group (36.39 ± 1.08 vs 36.63 ± 1.60 ng/ml, respectively p = 0.993). CONCLUSIONS: In the current study, telomerase activity or hTERT expression was similar in patients with ACS, SCAD, and controls. Moreover, telomerase activity was not associated with all- cause mortality during the 32-month follow-up (Tab. 3, Fig. 1, Ref. 29).

Despite being the second most often diagnosed form of cancer, lung cancers are rarely found in the general population. It is proposed in this study to employ a methodology of extracting both global and local features from CT scan images for the identification of lung cancer. Data gathering, globalised and localised training as well as testing the model are all part of this structure. This study makes use of 800 CT scan images. Images are pre-processed by warping and cropping in advance of the global testing step. Each image is represented by a feature vector employing eight distinct types of image characteristics, which are taken from the images. After creating feature vectors, three machine learning methods are employed to create detection models. Every medical image has been partitioned over a series of simple divisions throughout the training and testing process locally. To describe each block, feature vectors are derived from the image features that worked effectively in the general phase of the experiment. Similar extracted features are then used to build detection systems for all picture blocks using the learning strategies that were effective in the global stage. SVM using Haar Wavelet characteristics had an accuracy, sensitivity, and specificity of 89%, 90%, and 89%, respectively. One might get 90%‑accurate results with SVM and 91%‑sensitive and 91%‑specific results using SVM plus HOG features. Finally, the utilisation of SVM with Gabor Filter characteristics achieved the greatest correctness, specificity, and sensitivity values, particularly 87%, 86%, and 87%, respectively (Tab. 3, Fig. 7, Ref. 18). Keywords: feature extraction, support vector machine, lung cancer, classification, machine learning.

Clinical swabs with suspected viral infection are usually transported in virus transport medium (VMT). During epidemics/pandemics, tampons without VTM would be more suitable for saving space and cost. This study was conducted to verify the applicability of throat swabs without VTM in the diagnosis/screening of enteroviral infections by polymerase chain reaction (PCR) in a volunteer study group. Three different swab types were used in 40 volunteers: swabs with two different tips (cotton- or synthetic-tipped) without VTM and standard synthetic tips with VTM. The swabs were processed immediately or after 12 days of storage at either -80°C or +4°C. The molecular analysis included viral RNA extraction, and combination of reverse transcriptase PCR and nested PCR. Enteroviral RNA was detected in 15% (6/40) of the studied volunteers. When processed immediately, the results for all three swab types were compatible. Swabs without VTM may be used for collection of clinical samples in the diagnosis of suspected enteroviral infections or as potential screening tools for enteroviruses (Tab. 2, Ref. 15). Keywords: enterovirus infection, swab, transport medium, PCR, molecular diagnostics.

NTRODUCTION: The last two decades have been leading to the development of several types of surgical techniques and procedures to manage the LHB lesions. This paper analyses and compares the difference in muscle strength pre- and post-operatively in two most commonly used surgical procedures - LHB tenotomy and tenodesis. METHOD: The study includes 68 patients who underwent surgery between 2016 and 2020. The patients who had met the prospective study inclusion criteria were divided into two groups based on type of surgery they had undergone (LHB tenotomy or tenodesis); each group consisted of 34. The muscle strength during elbow flexion was measured preoperatively and postoperatively using the Commander Echo Console ultrasound muscle testing device. All patients enrolled in the study had been assessed for elbow flexion strength preoperatively. The muscle strength was measured preoperatively and then 3 years postoperatively (12 to 60 months) on average. CONCLUSION: The study confirmed that the patients who had undergone LHB tenodesis show a significantly lower decrease in elbow flexion strength and a significantly lower incidence of "Popeye" deformity than the patients after LHB tenotomy. Moreover, in the tenodesis group, it was possible to initiate rehabilitation earlier. The incidence of postoperative complications was almost identical in both groups of patients (Tab. 10, Fig. 6, Ref. 40).

The efficacy of taxane‑containing regimens has been demonstrated for various cancers, particularly ovarian, endometrial, breast, lung, and prostate cancers. However, extensive taxane-induced toxicities limit their use. Prediction and management of many toxic complications in cancer patients have evolved significantly over the last decade. Peripheral neuropathy is the most typical non-hematological taxane-related complication, and it has a multifactorial pathogenesis. It is often dose-dependent and progressive during therapy and sometimes even after treatment. Unfortunately, the prediction of these common adverse events remains unclear. In the past few years, several polymorphisms of candidate genes with a possible role in the development of this consequence were studied. This minireview aims to highlight the critical yet underappreciated roles of genetic predictors that may increase susceptibility to taxane-induced peripheral neuropathy in cancer patients (Ref. 40). Keywords: taxanes, paclitaxel, docetaxel, peripheral neuropathy, risk factors, genetic polymorphisms.
