RESUMO
Simultaneous breast augmentation with mastopexy is growing in popularity. It is a complex procedure that can lead to post-operative complications, patient dissatisfaction, and increased risk of litigation. The aim of this study is to describe an approach for the inverted-T augmentation-mastopexy technique, which limits intraoperative modifications, minimizes errors, and decreases post-operative complications and patient dissatisfaction. The study included 107 patients with Regnault's grade I and II ptosis and severe pseudoptosis. All patients were marked according to our novel technique, Mastopexy Augmentation Made Applicable and Safer (MAMAS), and operated by a single surgeon. All patients underwent simultaneous breast augmentation with Siltex Mentor Round Silicone Gel breast implants and mastopexy. Pre-operatively and post-operatively, patients filled the BREAST-Q. The mean follow-up was 24 months. Hundred and seven women received treatment in this study. Sixteen presented with post-operative complications, eleven in the early stage of recovery, and five in the late stage. There were eight cases of minor wound healing complications, all treated conservatively. Two cases of infection were noted, both were treated with oral antibiotics. One patient experienced post-operative bleeding after 13 days, which required surgical revision. In the late stage of recovery, five cases of implant displacement occurred and required revision surgery. No cases of capsular contracture and seromas were reported. According to Breast-Q, all patients were satisfied. MAMAS surgical technique, focusing on precise pre-operative marking for augmentation-mastopexy, is simple and easily reproducible. The procedure has a low complication rate and high patient satisfaction. It provides predictable and stable results over time.
RESUMO
PURPOSE: Trabecular bone score (TBS) is a grey-level textural measurement acquired from dual-energy X-ray absorptiometry lumbar spine images and is a validated index of bone microarchitecture. In 2015, a Working Group of the European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) published a review of the TBS literature, concluding that TBS predicts hip and major osteoporotic fracture, at least partly independent of bone mineral density (BMD) and clinical risk factors. It was also concluded that TBS is potentially amenable to change as a result of pharmacological therapy. Further evidence on the utility of TBS has since accumulated in both primary and secondary osteoporosis, and the introduction of FRAX and BMD T-score adjustment for TBS has accelerated adoption. This position paper therefore presents a review of the updated scientific literature and provides expert consensus statements and corresponding operational guidelines for the use of TBS. METHODS: An Expert Working Group was convened by the ESCEO and a systematic review of the evidence undertaken, with defined search strategies for four key topics with respect to the potential use of TBS: (1) fracture prediction in men and women; (2) initiating and monitoring treatment in postmenopausal osteoporosis; (3) fracture prediction in secondary osteoporosis; and (4) treatment monitoring in secondary osteoporosis. Statements to guide the clinical use of TBS were derived from the review and graded by consensus using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. RESULTS: A total of 96 articles were reviewed and included data on the use of TBS for fracture prediction in men and women, from over 20 countries. The updated evidence shows that TBS enhances fracture risk prediction in both primary and secondary osteoporosis, and can, when taken with BMD and clinical risk factors, inform treatment initiation and the choice of antiosteoporosis treatment. Evidence also indicates that TBS provides useful adjunctive information in monitoring treatment with long-term denosumab and anabolic agents. All expert consensus statements were voted as strongly recommended. CONCLUSION: The addition of TBS assessment to FRAX and/or BMD enhances fracture risk prediction in primary and secondary osteoporosis, adding useful information for treatment decision-making and monitoring. The expert consensus statements provided in this paper can be used to guide the integration of TBS in clinical practice for the assessment and management of osteoporosis. An example of an operational approach is provided in the appendix. This position paper presents an up-to-date review of the evidence base, synthesised through expert consensus statements, which informs the implementation of Trabecular Bone Score in clinical practice.

Hereditary angioedema (HAE) is a rare, inborn disease manifested with recurrent attacks of angioedema. They can affect the skin and subcutaneous tissue, mucous membranes (gastrointestinal, respiratory, and uropoietic tracts), and submucous tissue. Women in reproductive age require specific management of the disease regarding both the course of the disease and treatment options. It is not only the treatment in female patients that is specific, but also the situations (pregnancy, breastfeeding). We present a case report of the initial use of a subcutaneous C1 inhibitor in the long-term prophylaxis of HAE attacks in two pregnant patients.

A. baumannii imposes a great burden on medical systems worldwide. Surveillance of trends of antibiotic resistance provides a great deal of information needed for antimicrobial stewardship programmes nationwide. Clinical data from long-term, continuous surveillance on trends of antibiotic resistance of A. baumannii in Slovakia is missing. One hundred and forty-nine samples of A. baumannii were isolated over a period of four years. A panel of 19 antibiotics from seven antibiotic categories were tested for the bacterium's susceptibility. Resistance results were evaluated, and the significance of patterns was estimated using simple linear regression analysis. All isolates were more than 85% resistant to at least 13 out of the 19 tested antibiotics. A significant rise in resistance was recorded for aminoglycosides and imipenem from 2019 to 2022. Colistin and ampicillin-sulbactam have been the only antibiotics maintaining more than 80% efficacy on the bacterium to date. A significant rise in extensively drug-resistant (XDR) strains among carbapenem-resistant (CR) isolates has been recorded. Multidrug-resistance (MDR) among all A. baumannii isolates and XDR among CR strains of the bacterium have risen significantly in the last four years.
RESUMO
BACKGROUND: Despite long-term use of infliximab (IFX) in IBD treatment, its optimized use is unclear due to its complicated pharmacokinetics/dynamics. Hence, the predictive value of IFX trough levels (TL) is important in treatment management. METHODS: We performed a prospective, cross-sectional, observational study with 74 IBD patients treated with IFX (mean 9.1 years, SD ± 3). TL was measured during maintenance therapy, in which maintenance of remission was followed for 5 years. RESULTS: TL > 3 µg/ml during maintenance therapy was a significant predictor of clinical remission in 5 years in UC patients (82 % vs 62 %, p 3 µg/ml during maintenance therapy in a cohort of IBD patients (p = 0.05). Deviations in percentage of remission and fraction of relapses in TL categories were insignificant in a cohort of CD patients (85 % vs 74 %, p > 0.05). CONCLUSIONS: TL > 3 µg/ml during maintenance therapy is a strong predictor of sustained clinical remission for 5 years in UC patients. The use of combination therapy with AZA, due to its significant association with high TL, may have a practical benefit in achieving better clinical outcomes in UC patients (Tab. 2, Fig. 10, Ref. 20).

The coronavirus disease 2019 (COVID-19) pandemic has led to changes in lifestyle, which could influence vitamin D status on a population level. The purpose of our study was to compare 25-hydroxyvitamin D (25[OH]D) levels in patients hospitalized because of severe COVID-19 during two waves of the pandemic (2020/21 vs. 2021/22). A total of 101 patients from the 2021/22 wave were compared with 101 sex- and age-matched subjects from the 2020/21 wave. Patients from both groups were hospitalized during the winter season from 1 December to 28 February. Men and women were analyzed together and separately. The mean 25(OH)D concentration increased from 17.8 ± 9.7 ng/mL to 25.2 ± 12.6 ng/mL between waves. The prevalence of vitamin D deficiency (<20 ng/mL) decreased from 82% to 54%. The prevalence of adequate serum 25(OH)D concentration (>30 ng/mL) increased from 10% to 34% (p < 0.0001). The proportion of patients with a history of vitamin D supplementation increased from 18% to 44% (p < 0.0001). Low serum 25(OH)D concentration was independently associated with mortality after adjusting for age and sex for the whole cohort of patients (p < 0.0001). The prevalence of inadequate vitamin D status in hospitalized patients with COVID-19 in Slovakia decreased significantly, probably due to a higher rate of vitamin D supplementation during the COVID-19 pandemic.

Purpose: The present study aims to evaluate the effect of myo-Inositol plus Selenium supplementation in patients affected by subclinical hypothyroidism. Methods: One hundred and forty-eight patients were included in the study from 8 different centers of Slovakia, and treated for 6 months with a daily dose of 600 mg myo-Ins plus 83 mcg Se. The patients included at the enrollment were women of reproductive age (18-50), who exhibit values of TSH in the range 2.5-5 mU/l and positivity to antibodies TPO-Ab/TG-Ab, or otherwise values of TSH in the range 5-10 mU/l both with and without positivity to antibodies TPO-Ab/TG-Ab. Results: Patients affected by subclinical hypothyroidism exhibited a significant improvement of their condition when treated for 6 months with a combination of myo-Inositol and Selenium. The TSH values significantly ameliorated along with the index of autoimmunity and the thyroid status. In a sub-class of patients, the auto-antibody titer decreased after myo-inositol + Selenium administration. The treatment also induces a regularization of the menstrual cycle and a reduction of the cholesterol in the patients enrolled for the study. Furthermore, a significant improvement is observed in the perception of the symptoms associated with subclinical hypothyroidism over the treatment period. Conclusion: A dietary supplementation with of myo-Inositol and Selenium in the treatment of patients affected by subclinical hypothyroidism exhibits a beneficial role in the recovery of TSH values, in the improvement of the symptoms associated to this condition and in the maintenance of the thyroid functions.The trial was approved by the Ethical Committee from National Institute of Endocrinology and Diabetology of Lubochna, Slovakia, date 18.12.2018, registration number: 3124/2018.

Despite improvements in surgical techniques, current radiotherapy options and development of long-acting somatostatin analogues, biochemical control of acromegaly is not achieved in some patients. The failure to achieve optimal serum growth hormone (RH) and insulin-like growth factor-1 (IGF-1) levels means increased morbidity and mortality of acromegaly patients. The RH receptor antagonist pegvisomant (PEG) is a genetically engineered RH analog that prevents of RH receptor dimerization, i.e. a process that is crucial for the action of RH at the cellular level. The effect of the treatment is suppression of IGF-1 production. In pilot studies, normalization of IGF-1 levels was achieved in up to 90 % of patients receiving PEG. However, PEG efficacy in clinical settings is slightly lower (65 to 97 %) than reported in the key studies. A rare side effect of treatment is elevations of liver transaminases. In addition, pituitary tumor growth progression has been reported in several cases. In this review article, we present long-term data on pegvisomant treatment and discuss its associated risks and benefits.

BACKGROUND: Enterococcus species account for most of the human enterococcal HAI and multidrug-resistant infections and have become a major threat to modern public health. We examine the rise in the number of vancomycin resistant E. faecium blood stream and urinary tract infections in a COVID-19 department during an epidemiologic outbreak investigation to detect and eliminate nosocomial clusters of the bacteria. METHODS: Strain identification was performed by classical isolation and biochemical and cultivation methods. Antibiotic testing results were interpreted according to European committee on antimicrobial susceptibility testing (EUCAST) guidelines. Six isolated samples underwent the whole genome sequencing (WGS) during the outbreak investigation. Isolate relatedness was determined using the core genome multi-locus sequence typing. RESULTS: WGS revealed two genotypically distinct VRE clusters, one of which had genetically closely related patients and environmental isolates. The cluster was terminated by enhanced infection control strategies. CONCLUSIONS: This study provides the first description of an outbreak caused by vanB-ST117 and vanA-ST17 E. faecium strains among COVID-19 patients in Slovakia. This study can help to raise the awareness about the need for strict adherence to infection control measures and the implementation of rational antimicrobial stewardship as a routine part of COVID-19 management (Tab. 3, Fig. 3, Ref. 27).

Administration of biological therapy (BT) in rheumatoid arthritis (RA) patients is often associated with hematological complications, which result in switching among therapies. Thus, there is an instant need for suitable screening parameters that will help to individualize the therapy and minimize the onset of adverse effects. We analyzed the hematological profile of 99 RA patients receiving TNFα (Adalimumab - ADA, Golimumab - GOL, Etanercept - ETA) or IL-6 receptor (Tocilizumab - TCZ) inhibitors in order to find possible indicators to improve personalization of RA therapy. BTs significantly affect the levels of observed hematological parameters. In contrast to TNF-α inhibitors, TCZ normalized almost all monitored hematological parameters to values of healthy donors. Only GOL from the TNF-α inhibitors studied, was able to normalize neutrophil counts, as well as platelet indicators. Importantly, effects on the blood parameters (e.g. lymphocytes or platelet count) differ even within the same therapeutic group (anti-TNFα). Variable effects of individual biological agents in RA treatment point to importance to evaluate the patient's hematological profile to improve the selection of suitable BT. It will help to personalize the administration of BT and prevent unnecessary switching from an effective therapy just because of provocation of avoidable hematological complications.
RESUMO
It is unclear how ongoing inflammation in Coronavirus Disease 2019 (COVID-19) affects 25-hydroxyvitamin D (25[OH]D) concentration. The objective of our study was to examine serum 25(OH)D levels during COVID-19 pneumonia. Patients were admitted between 1 November and 31 December 2021. Blood samples were taken on admission (day 0) and every 24 h for the subsequent four days (day 1−4). On admission, 59% of patients were 25(OH)D sufficient (>30 ng/mL), and 41% had 25(OH)D inadequacy (<30 ng/mL). A significant fall in mean 25(OH)D concentration from admission to day 2 (first 48 h) was observed (30.7 ng/mL vs. 26.4 ng/mL; p < 0.0001). No subsequent significant change in 25(OH)D concentration was observed between day 2 and 3 (26.4 ng/mL vs. 25.9 ng/mL; p = 0.230) and day 3 and day 4 (25.8 ng/mL vs. 25.9 ng/mL; p = 0.703). The absolute 25(OH)D change between hospital admission and day 4 was 16% (4.8 ng/mL; p < 0.0001). On day 4, the number of patients with 25(OH)D inadequacy increased by 18% (p = 0.018). Therefore, serum 25(OH)D concentration after hospital admission in acutely ill COVID-19 patients should be interpreted with caution. Whether low 25(OH)D in COVID-19 reflects tissue level vitamin D deficiency or represents only a laboratory phenomenon remains to be elucidated in further prospective trials of vitamin D supplementation.

Vitamin D deficiency has a high worldwide prevalence, but actions to improve this public health problem are challenged by the heterogeneity of nutritional and clinical vitamin D guidelines, with respect to the diagnosis and treatment of vitamin D deficiency. We aimed to address this issue by providing respective recommendations for adults, developed by a European expert panel, using the Delphi method to reach consensus. Increasing the awareness of vitamin D deficiency and efforts to harmonize vitamin D guidelines should be pursued. We argue against a general screening for vitamin D deficiency but suggest 25-hydroxyvitamin D (25(OH)D) testing in certain risk groups. We recommend a vitamin D supplementation dose of 800 to 2000 international units (IU) per day for adults who want to ensure a sufficient vitamin D status. These doses are also recommended for the treatment of vitamin D deficiency, but higher vitamin D doses (e.g., 6000 IU per day) may be used for the first 4 to 12 weeks of treatment if a rapid correction of vitamin D deficiency is clinically indicated before continuing, with a maintenance dose of 800 to 2000 IU per day. Treatment success may be evaluated after at least 6 to 12 weeks in certain risk groups (e.g., patients with malabsorption syndromes) by measurement of serum 25(OH)D, with the aim to target concentrations of 30 to 50 ng/mL (75 to 125 nmol/L).

We studied whether elderly women at risk for fractures receive primary care treatment to prevent fracture. We found that across Europe, women at risk are often not identified, and less than half of such women receive appropriate treatment. Finally, women diagnosed with osteoporosis are much more likely to receive treatment. PURPOSE: To examine the relationship between risk factors for fragility fracture (FF) and osteoporosis (OP) treatment gap in elderly women across Europe, and compare the prevalence of risk factors between countries. METHODS: Demographic and clinical information was collected from women ≥ 70 years visiting primary care physicians in Belgium, France, Germany, Ireland, Poland, Slovakia, Switzerland, and the UK. Increased risk of FF was defined by the presence of 1 or more criteria (history of fracture, 10-year fracture probability, or T-score ≤ - 2.5). RESULTS: There were 3798 women in total. Treatment gap (proportion at increased risk of FF not receiving treatment for OP) varied from 53.1 to 90.8% across countries, and the proportion of patients at increased risk of FF varied from 41.2 to 76.1%. Across countries, less than 50% of patients with increased risk of FF had a diagnosis of OP. Previous fracture was the most common risk factor, with similar prevalence across most countries; other risk factors varied widely. The treatment gap was reduced in patients with an OP diagnosis in all countries, but this reduction varied from 36.5 to 79.4%. The countries with the lowest rates of bone densitometry scans (Poland, France, and Germany; 8.3-12.3%) also had the highest treatment gap (82.2 to 90.8%). CONCLUSIONS: This study highlights differences across Europe in clinical risk factors for fracture, rates of densitometry scanning, and the rates of OP diagnosis. More emphasis is needed on risk assessment to improve the identification and treatment of elderly women at risk for fracture.

OBJECTIVES: There is no consensus on specific serum 25-hydroxy vitamin D (25(OH) D) levels associated with higher risk of severe outcome in patients with coronavirus disease 2019 (COVID-19). According to the literature patients with serum 25(OH) D levels <12 ng/ml are clearly deficient at all ages. Our aim was to assess COVID-19 mortality in the settings of severe 25(OH) D deficiency. A cohort study of 357 patients with COVID-19 was conducted. Subjects were monitored until discharge or in-hospital death. At admission, severity parameters (C-reactive protein (CRP), IL-6, Charlson comorbidity index, etc.) were assessed. These parameters were compared regarding 25(OH) D levels threshold 12 ng/ml, where values below 12 ng/ml were considered absolute vitamin D deficiency. RESULTS: 25(OH) D levels at the time of admission were independently associated with mortality (p <0.05). Nonsurvivors (N = 168) had lower 25(OH) D levels, SO2, higher age, CRP, viral load, and Charlson comorbidity index in comparison to survivors. Patients with serum 25(OH) D levels <12 ng/ml had higher mortality (55% vs 45 %), viral load (21.5 vs 23.1), and Charlson comorbidity index (5.3 vs 4.4) than those with serum 25(OH) D levels >12 ng/ml (p <0.05). CONCLUSIONS: Patients with COVID-19 with serum 25(OH) D levels <12 ng/ml have higher mortality. Among other factors, severe vitamin D deficiency likely leads to poor outcome.

Aim: Afamin is a liver-produced glycoprotein, a potential early marker of metabolic syndrome. Here we investigated regulation of afamin in a course of the metabolic disease development and in response to 3-month exercise intervention. Methods: We measured whole-body insulin sensitivity (euglycemic hyperinsulinemic clamp), glucose tolerance, abdominal adiposity, hepatic lipid content (magnetic resonance imaging/spectroscopy), habitual physical activity (accelerometers) and serum afamin (enzyme-linked immunosorbent assay) in 71 middle-aged men with obesity, prediabetes and newly diagnosed type 2 diabetes. Effects of 3-month exercise were investigated in 22 overweight-to-obese middle-aged individuals (16M/6F). Results: Prediabetes and type 2 diabetes, but not obesity, were associated with increased serum afamin (p<0.001). Afamin correlated positively with hepatic lipids, fatty liver index and liver damage markers; with parameters of adiposity (waist circumference, %body fat, adipocyte diameter) and insulin resistance (fasting insulin, C-peptide, HOMA-IR; p<0.001 all). Moreover, afamin negatively correlated with whole-body insulin sensitivity (M-value/Insulin, p<0.001). Hepatic lipids and fasting insulinemia were the most important predictors of serum afamin, explaining >63% of its variability. Exercise-related changes in afamin were paralleled by reciprocal changes in insulinemia, insulin resistance and visceral adiposity. No significant change in hepatic lipid content was observed. Conclusions: Subjects with prediabetes and type 2 diabetes had the highest serum afamin levels. Afamin was more tightly related to hepatic lipid accumulation, liver damage and insulin resistance than to obesity.

CONTEXT: Recent studies suggest that cortical bone could also play a role in vertebral fracture (VF) development in acromegaly. OBJECTIVE: Evaluate the occurrence of VFs and their relationship to dual energy x-ray absorptiometry-derived bone parameters. METHODS: A single-center 2-year prospective study of acromegaly patients was conducted. Each subject had L1-4 spine, femoral neck and total hip (TH) areal BMD measured using DXA, and trabecular bone score (TBS) measurement performed. 3D Shaper™ was used to assess proximal femur trabecular and cortical volumetric (v)BMD, cortical surface (s)BMD, and cortical thickness (Cth). VF assessment was performed using the lateral spine imaging IVA™ mode with a Hologic Horizon® densitometer using a semiquantitative approach. Study outcomes were assessed at 2 time points: baseline and month 24. RESULTS: 70 acromegaly patients (34 M/36F; average 55.1 years) were studied, including 26 with active disease. In 13 patients, 9 with controlled disease, VF was observed. A decrease in TBS, sBMD, neck trabecular vBMD, TH, and neck cortical vBMD in VF compared with non-VF subjects was observed (Pâ <â .05). Multivariate analysis of fracture prediction showed TH cortical vBMD as the best fracture prediction parameter with area under the curve of 0.774. TBS was negatively associated with fasting plasma glucose and glycated hemoglobin (HBA1c) at each time point during the follow-up. CONCLUSION: From the total number of 13 VF subjects, 9 were in the controlled disease group. The most sensitive and specific predictor of incident VF was TH cortical vBMD, suggesting that cortical bone is involved in fracture development.

The new coronavirus SARS-CoV-2 is responsible for the development of acute infectious illness named COVID-19. While most people have a mild course of the disease, a significant minority of patients will develop some degree of respiratory insufficiency requiring hospitalization. In case of failure of conventional oxygen therapy, the method of choice in patients with respiratory insufficiency is ventilation with high-flow nasal cannula (HFNC). In order to reduce the dispersion of infectious aerosol during HFNC treatment, nasal cannula is often covered with a surgical mask in many hospitals. According to recent observations, the application of a surgical mask in these patients could also have a positive effect on oxygenation parameters without clinically relevant side effects. In the present set of case reports, we demonstrate this effective, simple and affordable way how to improve oxygenation in patients with COVID-19 and hypoxemic respiratory failure treated with HFNC.

In contrast to postmenopausal women diagnostic process and treatment of premenopausal osteoporosis in young women reamin poorly defined. A low bone mineral density in premenopausal women is not associated with the same risk of fractures as in postmenopausal women, therefore diagnosis requires not only densitometric examination but depends on the consideration of other risk factors. Most cases of premenopausal osteoporosis are associated with chronic diseases affecting bone metabolism. Treatment of the underlying disease may improve bone density as well as bone quality. Rarely, a bone-specific antiporotic therapy may be used, although quality evidence is scarce. This article will review current opinion on definition, diagnosis and treatment of premenopausal osteoporosis.

Diabetes mellitus (DM) is currently a pandemic problem, and the number of diabetic patients is constantly increasing. There are known and established diabetic complication but it is also comorbidities associated with DM cannot be forgotten. One of these is osteoporosis and osteoporotic fractures. In diabetic patients, the fractures are usually 2 to 6 times higher. In management of diabetes we should screen also the risk of osteoporosis and fractures. From a diabetic point of view, optimum glycaemic control should be achieved, however, we should take into account the effect of antidiabetic agents on bone. In this summary data on the diagnosis and treatment of osteoporosis in patients with DM as well as on the effect of antidiabetic agents on bone are presented.

The purpose of this study was to investigate the impact of eggshell calcium (Biomin H® dietary supplement) and its combinations with alfacalcidol (1α-hydroxyvitamin D3 ) and menaquinone-7 (vitamin K2 ) on ovariectomy-induced bone loss in rats. Adult female rats (n = 48) were divided into 6 groups of 8 individuals each: sham-operated rats (SHAM); ovariectomized (OVX) rats untreated; OVX rats treated with Biomin H® (BIO); OVX rats simultaneously receiving Biomin H® , vitamin D3 (BIO + D3 ); OVX rats simultaneously treated with Biomin H® , vitamin K2 (BIO + K2 ) and OVX rats treated with Biomin H® , vitamin D3 , vitamin K2 (BIO + D3 + K2 ) during 8 weeks. Biochemical parameters, bone mineral density (BMD), bone mineral content (BMC) and femoral bone microstructure were determined. Plasma calcium and phosphate were increased in BIO + D3 and BIO + D3 + K2 groups as compared to OVX. Alkaline phosphatase was elevated in OVX, BIO versus SHAM, BIO + D3 + K2 groups. When compared to OVX group, decreased urine deoxypyridinoline was observed in all treated groups and femoral BMD, BMC were higher in BIO, BIO + D3 , BIO + D3 + K2 groups. The BIO + K2 rats had similar densitometrical values than OVX individuals. Microcomputed tomography revealed increased trabecular relative bone volume (due to an increase in trabecular number) in BIO + D3 , BIO + D3 + K2 as compared to OVX. The higher relative bone volume in BIO + D3 , BIO + D3 + K2 groups was also accompanied by an increase in bone surface. In the cortical bone, an enhanced periosteal bone apposition was identified in BIO, BIO + D3 , BIO + K2 , BIO + D3 + K2 groups. The rats from BIO + D3 + K2 group had a higher area of primary osteon's vascular canals. In BIO + D3 , BIO + K2 , BIO + D3 + K2 groups, an increased area of secondary osteons was determined in comparison with OVX. Our results indicate the beneficial effect of triple application of Biomin H® , vitamin D3 , vitamin K2 , as well as simultaneous administration of Biomin H® , vitamin D3 on the inhibition of ovariectomy-induced bone loss in a rat model of osteoporosis.
