RESUMO

1. Tibial dyschondroplasia (TD) is a skeletal disorder in broilers that has financial implications, necessitating dietary modifications to reduce the prevalence of this disease. This study explored how arginine silicate inositol complex (ASI) supplementation affected tibial growth plate (TGP) and overall bone health in broilers with manganese (Mn) deficiency-induced TD.2. A total of 240 broiler chicks were divided into four groups, each consisting of 60 birds (15 replicates of four broilers each) as follows: i) Control, with 60 mg Mn per kg of diet; ii) ASI, with 60 mg Mn and 1 g ASI per kg of diet; iii) TD, with 22 mg Mn per kg of diet, and iv) TD+ASI, with 22 mg Mn and 1 g ASI per kg of diet.3. It was found that ASI supplementation increased tibial bone length in Mn-deficient TD broilers (p = 0.007). There was no Mn x ASI interaction for other bone morphometry variables (p > 0.05). However, both tibial bone mineral content and density were affected by Mn and ASI (p < 0.05). With ASI supplementation, serum bone-specific alkaline phosphatase and osteocalcin levels were elevated in the TD+ASI group compared to the TD group (p < 0.001). In the TD group, osteoprotegerin (OPG) levels in the TGP decreased compared to the control groups (p < 0.001).4. In contrast, ASI supplementation in the TD broilers counteracted the decrease in OPG compared to TD broilers without ASI supplementation (p < 0.001). The Mn level and ASI supplementation significantly influenced the OPG/receptor activator of the nuclear factor-κB ligand ratio (p < 0.001).5. In conclusion, the results demonstrated that inclusion of ASI in broiler diets could enhance bone formation variables by controlling OPG levels in the TGP, potentially serving as an effective method to decrease the occurrence of TD.

RESUMO

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is a factor that implicate in the pathophysiology and treatment of depression and anxiety. The aim of this study was to determine the relationship between dental anxiety and BDNF serum level through impacted third molar surgery. MATERIAL AND METHODS: In this randomized, double-blind, cross-sectional study, the sample included patients who had been admitted for the impacted third molar extraction under local anesthesia between January to November 2020. The primary predictor variable was serum BDNF level and the second predictor variable was dental anxiety scores before and after operation in patients. The primary outcome variable was the correlation between anxiety scores (APAIS, MDAS, STAI, VAS) and serum BDNF level. The sample included 55 patients (22 Male, 33 Female) aged 18 to 42 (24,2+5,55). RESULTS: Comparison of pre-operative scores (APAIS, MDAS, STAI, VAS and BDNF) and post-operative scores were statistically significant (P < .05). Post-operatively, MDAS and VAS scores decreased, while BDNF levels and STAI scores increased compared to the preoperative scores. BDNF was not correlated with APAIS, MDAS, STAI, and VAS preoperatively and postoperatively. CONCLUSIONS: There may be a relationship between serum BDNF level and dental anxiety scale, but, no correlation was found between them.

RESUMO

BACKGROUND: Sleep, which is crucial for restoring of physiological functions and health, is reportedly impaired in psoriasis. The role of different potential sleep confounding factors, including detailed pruritus characteristics, and the complex interplay between psychological variables (anxiety and depression), pruritus and sleep disturbance in psoriasis remain insufficiently investigated. OBJECTIVES: To investigate sleep characteristics and to identify clinical, demographic and psychological factors associated with sleep disturbance in psoriasis. METHODS: This cross-sectional study included 334 psoriasis patients (response rate 86%) and 126 control subjects (response rate 82%). Measures included sleep quality [Pittsburgh Sleep Quality Index (PSQI)], psoriasis severity, pruritus characteristics, including average pruritus intensity [visual analogue scale (VAS)], severity of comorbidities, anxiety and depression (Hospital Anxiety and Depression Scale - HADS) and quality of life (Dermatology Life Quality Index - DLQI, and Short Form 12 - SF12). RESULTS: Fifty-nine per cent of patients and 34% of control subjects (P < 0.001) suffered from sleep disturbance (PSQI > 5). Patients slept 1 h less than control subjects (median 6 vs. 7 h, P < 0.001). Patients without pruritus had less impaired sleep (global PSQI) than patients with strong (P < 0.001) and very strong pruritus (P < 0.001). Anxiety (HADS-A) and depression (HADS-D) levels were the strongest predictors of sleep impairment, followed by pruritus exacerbation at night, age, female sex, pruritus exacerbation in the morning, average pruritus intensity (VAS), diagnosed depression and gastroesophageal reflux disease, altogether explaining 32%-37% of the variance in global sleep quality. Both anxiety (HADS-A) and depression (HADS-D) were significant mediators explaining the association between pruritus intensity (VAS) and sleep impairment in 42% and 37% respectively. CONCLUSIONS: Sleep disturbance in patients with psoriasis is highly prevalent. Patients with psoriasis should be assessed for sleep impairment, pruritus, anxiety and depression. Reduction in pruritus should be considered as an important therapeutic goal, along with therapies aimed at reducing anxiety and depression.

RESUMO

BACKGROUND: Pruritus is prevalent in psoriasis but still many features of pruritus, its response to therapy and its burden in psoriasis remain to be better characterized. OBJECTIVE: To investigate characteristics and burden of pruritus in an international cohort of patients with psoriasis. METHODS: This cross-sectional study included a total of 634 patients and 246 controls from Germany, Poland and Russia. Physicians examined and interviewed participants, recording clinical characteristics, such as severity, therapy and localization of psoriatic lesions. Participants filled out self-reported questionnaires including questions on pruritus severity and impact, characteristics, and response to therapy, and quality of life (QoL). Localization patterns of pruritus and skin lesions were visualized using body heat maps. RESULTS: Most patients (82%) experienced pruritus throughout their disease, and 75% had current pruritus. The majority of patients (64%) perceived pure pruritus, and those who reported additional painful and/or burning sensations (36%) reported overall stronger pruritus. The scalp was the most frequently reported localization of pruritus, even in the absence of skin lesions. Body surface area (BSA) of pruritus was not linked to pruritus intensity, but to BSA of psoriatic lesions (rho = 0.278; P < 0.001). One third of patients (31%) reported impaired sex-life, and 4% had suicidal ideations due to pruritus. In up to one third of patients, psoriasis therapies had little or no effect on pruritus. The only therapeutic option offered to some of these patients were antihistamines, which appeared to be effective in most cases. CONCLUSION: Pruritus is highly prevalent in psoriasis and is linked to a significant burden. Current psoriasis therapies are frequently insufficient to control pruritus. Managing psoriasis should include the assessment and control of itch. Efficient antipruritic therapies should be developed and be made available for patients with psoriasis.

RESUMO

PURPOSE: This study aimed to determine the potential clinical use of dynamic thiol-disulfide balance in cases with preinvasive lesions of the cervix. METHODS: One hundred and sixteen patients with high-grade squamous intraepithelial lesion, 100 patients with low-grade squamous intraepithelial lesion, and 110 healthy controls were enrolled in the study. A fully automated colorimetric system was used to determine the levels of thiol-disulfide parameters. The ischemia-modified albumin, total oxidant-antioxidant capacity, and oxidative stress index of the retrieved cases were further analyzed. RESULTS: Native thiol and total thiol levels are significantly lower in the high-grade squamous intraepithelial lesion group according to control group (p: 0.004 and 0.015, respectively). Disulfide level is significantly increased in the high-grade squamous intraepithelial lesion group compared to control group (p: 0.004). Oxidative stress index levels in high-grade squamous intraepithelial lesion group were observed as significantly higher according to the control group (p: 0.014). Ischemia-modified albumin levels in the high-grade squamous intraepithelial lesion group were observed as significantly higher compared to the control group (p: 0.020). Disulfide levels are positively correlated with risk type of Human papillomavirus (r: 0.420, p < 0.001). CONCLUSION: The analysis of dynamic thiol-disulfide balance revealed considerable oxidative damage in patients with Human papillomavirus-related cervical precursor lesions compared to women with ordinary cytology specimens. Therefore, investigation of thiol-disulfide balance with presented method represents a new promising test for early diagnosis and management of women at high risk for cervical cancer.

RESUMO

The validity of the Brink-Axel hypothesis, which is especially important for numerous astrophysical calculations, is addressed for ^{116,120,124}Sn below the neutron separation energy by means of three independent experimental methods. The γ-ray strength functions (GSFs) extracted from primary γ-decay spectra following charged-particle reactions with the Oslo method and with the shape method demonstrate excellent agreement with those deduced from forward-angle inelastic proton scattering at relativistic beam energies. In addition, the GSFs are shown to be independent of excitation energies and spins of the initial and final states. The results provide a critical test of the generalized Brink-Axel hypothesis in heavy nuclei, demonstrating its applicability in the energy region of the pygmy dipole resonance.

RESUMO

We studied the proton-rich T_{z}=-1 nucleus ^{70}Kr through inelastic scattering at intermediate energies in order to extract the reduced transition probability, B(E2;0^{+}→2^{+}). Comparison with the other members of the A=70 isospin triplet, ^{70}Br and ^{70}Se, studied in the same experiment, shows a 3σ deviation from the expected linearity of the electromagnetic matrix elements as a function of T_{z}. At present, no established nuclear structure theory can describe this observed deviation quantitatively. This is the first violation of isospin symmetry at this level observed in the transition matrix elements. A heuristic approach may explain the anomaly by a shape change between the mirror nuclei ^{70}Kr and ^{70}Se contrary to the model predictions.

RESUMO

The cascading 3.21 and 4.44 MeV electric quadrupole transitions have been observed from the Hoyle state at 7.65 MeV excitation energy in ^{12}C, excited by the ^{12}C(p,p^{'}) reaction at 10.7 MeV proton energy. From the proton-γ-γ triple coincidence data, a value of Γ_{rad}/Γ=6.2(6)×10^{-4} was obtained for the radiative branching ratio. Using our results, together with Γ_{π}^{E0}/Γ from Eriksen et al. [Phys. Rev. C 102, 024320 (2020)PRVCAN2469-998510.1103/PhysRevC.102.024320] and the currently adopted Γ_{π}(E0) values, the radiative width of the Hoyle state is determined as Γ_{rad}=5.1(6)×10^{-3} eV. This value is about 34% higher than the currently adopted value and will impact models of stellar evolution and nucleosynthesis.

RESUMO

BACKGROUND: Combination of hydroxychloroquine and azithromycin for the treatment of coronavirus disease 2019 (COVID-19) carries increased risk of corrected QT (QTc) prolongation and cardiac arrhythmias. OBJECTIVE:  To characterize the ventricular repolarization indexes which are associated with malignant ventricular arrhythmias in patients treated with hydroxychloroquine and concomitant azithromycin for COVID-19. METHOD: A total of 81 patients who had hydroxychloroquine and azithromycin combination therapy because of possible or  reverse-transcription polymertase chain reaction (RT-PCR) confirmed diagnosis of COVID-19 were included in the study. Baseline and control electrocardiograms (before and after treatment) were analyzed retrospectively. Tp-e interval, Tp-e/QT and Tp-e/QTc ratios, which are ventricular repolarization indexes, were calculated. RESULTS: While there was no significant increase in QTc interval in patients receiving combination therapy, there was a significant increase in ventricular repolarization indexes. CONCLUSION: The increase in ventricular replarization indexes is associated with the risk of arrhythmia. In patients using QTc prolonging medication for COVID-19 treatment, QTc monitoring alone may not be sufficient to follow-up for arrhythmia. Even if there is no prolongation in QTc, an increase in ventricular repolarization indexes may be seen (Tab. 5, Ref. 37).

RESUMO

PURPOSE: In this study, we aimed to investigate the relationship between hypothyroidism and sterile inflammation in rat heart tissue. METHODS: Groups; control group (fed with standard rat chow diet and tab water) and the hypothyroid group (fed with a standard rat chow diet and tap water containing 0.05% 6-n-propyl-2-thiouracil for 6-weeks). At the end of the experiment, histopathologic examination was performed. The T3, T4, TSH and myocardial malondialdehyde (MDA) measurements were performed with an ELISA kit. TUNEL assay was performed to demonstrate apoptosis. Sterile inflammation markers, caspase-1 and NLRP3, were investigated by immunohistochemistry and western blot. RESULTS: In histopathological examination, we observed leukocyte infiltration, myocardial atrophy, pyknotic nucleated cells and cytoplasmic vacuolization in hypothyroid group whereas the control group showed normal structure. MDA levels in myocardial tissue were significantly high in hypothyroid group when compared to the control group (P<0.05). Myocardial apoptosis increased in hypothyroid group when compared to the control group. NLRP3 and caspase-1 immunoreactivity was higher in the hypothyroid group. In ELISA results, we found significantly higher level of TSH and lower levels of T3 and T4 in hypothyroid group when compared to the control group. CONCLUSION: Hypothyroidism increased oxidative stress, and caused inflammatory alterations in cardiac tissue. In addition, our study also suggested that thyroid hormone deficiency would increase the amounts of cardiac NLRP3 and caspase-1 protein, which indicates that hypothyroidism exerts its destructive effects through sterile inflammation. Elucidation of sterile inflammation-associated pathways may produce promising results in the treatment of hypothyroidism-induced cardiac damage.

RESUMO

The lifetimes of the first excited 2^{+}, 4^{+}, and 6^{+} states in ^{98}Zr were measured with the recoil-distance Doppler shift method in an experiment performed at GANIL. Excited states in ^{98}Zr were populated using the fission reaction between a 6.2 MeV/u ^{238}U beam and a ^{9}Be target. The γ rays were detected with the EXOGAM array in correlation with the fission fragments identified by mass and atomic number in the VAMOS++ spectrometer. Our result shows a very small B(E2;2_{1}^{+}→0_{1}^{+}) value in ^{98}Zr, thereby confirming the very sudden onset of collectivity at N=60. The experimental results are compared to large-scale Monte Carlo shell model and beyond-mean-field calculations. The present results indicate the coexistence of two additional deformed shapes in this nucleus along with the spherical ground state.

RESUMO

BACKGROUND: Nausea and vomiting occur 50-90% during the first trimester of pregnancy. However, patients with hyperemesis gravidarum (HG) may be hospitalized at an incidence rate of 0.8-2% before the 20th week of gestational age. The symptoms generally start during the 5-6th gestational weeks, reaching the highest degree during the 9th week, and decline after the 16-20th weeks of gestation. Clinical findings are proportional to the severity of the disease and severe HG is characterized with dehydration, electrolyte imbalance, and nutritional deficiency as a result of vomiting. METHODS: The study population consisted of two groups of pregnant volunteers at 5-12 weeks of gestation: a severe HG group and a control group. The HG severity was scored using the Pregnancy-Unique Quantification of Emesis (and nausea) (PUQE).The serum levels of the maternal Ca, parathyroid hormone (PTH), Na, K, blood urea nitrogen(BUN), creatinine, vitamin D(25OHD3), and the maternal urine NTx levels were compared between the groups. RESULTS: In total, 40 volunteers were enrolled in this study: 20 healthy pregnant volunteers and 20 with severe HG. There were no statistically significant differences between the maternal characteristics. The first trimester weight loss of ≥5 kg was significantly higher in the severe HG group (p < 0.001), while the control group had a significantly higher sunlight exposure ratio than the severe HG group (p = 0.021). The urine NTx levels were significantly higher in the severe HG group (39.22 ± 11.68NTx/Cre) than in the control group(32.89 ± 8.33NTx/Cre) (p = 0.028).The serum Ca, PTH, Na, K, BUN, and creatinine levels were similar between the groups (p = 0.738, p = 0.886, p = 0.841, p = 0.957, p = 0.892, and p = 0.824, respectively). In the severe HG group, the serum 25OHD3 levels were significantly lower than in the control group (p < 0.001). CONCLUSIONS: The data from this study indicated that severe HG is associated with increased urine NTx levels. However, large-scale studies are required to understand the clinical significance of this finding, as well as the long-term consequences of elevated urine NTx levels and the underlying mechanisms.

RESUMO

This study compared the antiproliferative effects of metformin and progesterone, via examination of the Bcl-2/Bax-caspase apoptotic pathway in estrogen-induced endometrial hyperplasia (EH) in 40 rats. Two rats died after bilateral oophorectomy, and 1 week after surgery, the remaining 38 were randomly divided into three groups: the first (control, n = 12) received 4 mg/kg 17ß estradiol hemihydrate (E); the second (n = 13) received 4 mg/kg 17ß estradiol hemihydrate and 50 mg/kg metformin (E + M); and the third (n = 13) received 4 mg/kg 17ß estradiol hemihydrate and 1 mg/day medroxiprogesterone acetate (E + MPA). Histological markers and Bcl-2, Bax and caspase 9 expression were analyzed. Luminal epithelial thickness, density of gland and epithelial height was significantly higher in group E than in groups E + M and E + MPA. Histopathologic parameters were similar between the E + M and E + MPA groups. Bcl-2/Bax ratio was significantly decreased in the E + M and E + MPA groups and caspase 9 expression levels were significantly increased in the E + M and E + MPA groups, compared with the control group. In addition, Bcl-2/Bax ratio and caspase 9 expression were similar between the E + M and E + MPA groups. The data indicate that metformin reduces estrogen-induced EH in rats, via activation of the caspase-dependent mitochondrial apoptotic pathway, to the same degree as progesterone.

RESUMO

Excited states in the nucleus ^{133}Sn, with one neutron outside the double magic ^{132}Sn core, were populated following one-neutron knockout from a ^{134}Sn beam on a carbon target at relativistic energies at the Radioactive Isotope Beam Factory at RIKEN. Besides the γ rays emitted in the decay of the known neutron single-particle states in ^{133}Sn additional γ strength in the energy range 3.5-5.5 MeV was observed for the first time. Since the neutron-separation energy of ^{133}Sn is low, S_{n}=2.402(4) MeV, this observation provides direct evidence for the radiative decay of neutron-unbound states in this nucleus. The ability of electromagnetic decay to compete successfully with neutron emission at energies as high as 3 MeV above threshold is attributed to a mismatch between the wave functions of the initial and final states in the latter case. These findings suggest that in the region southeast of ^{132}Sn nuclear structure effects may play a significant role in the neutron versus γ competition in the decay of unbound states. As a consequence, the common neglect of such effects in the evaluation of the neutron-emission probabilities in calculations of global ß-decay properties for astrophysical simulations may have to be reconsidered.

RESUMO

Fast-neutron-induced fission of ^{238}U at an energy just above the fission threshold is studied with a novel technique which involves the coupling of a high-efficiency γ-ray spectrometer (MINIBALL) to an inverse-kinematics neutron source (LICORNE) to extract charge yields of fission fragments via γ-γ coincidence spectroscopy. Experimental data and fission models are compared and found to be in reasonable agreement for many nuclei; however, significant discrepancies of up to 600% are observed, particularly for isotopes of Sn and Mo. This indicates that these models significantly overestimate the standard 1 fission mode and suggests that spherical shell effects in the nascent fission fragments are less important for low-energy fast-neutron-induced fission than for thermal neutron-induced fission. This has consequences for understanding and modeling the fission process, for experimental nuclear structure studies of the most neutron-rich nuclei, for future energy applications (e.g., Generation IV reactors which use fast-neutron spectra), and for the reactor antineutrino anomaly.

RESUMO

The level structure of the neutron-rich ^{77}Cu nucleus is investigated through ß-delayed γ-ray spectroscopy at the Radioactive Isotope Beam Factory of the RIKEN Nishina Center. Ions of ^{77}Ni are produced by in-flight fission, separated and identified in the BigRIPS fragment separator, and implanted in the WAS3ABi silicon detector array, surrounded by Ge cluster detectors of the EURICA array. A large number of excited states in ^{77}Cu are identified for the first time by correlating γ rays with the ß decay of ^{77}Ni, and a level scheme is constructed by utilizing their coincidence relationships. The good agreement between large-scale Monte Carlo shell model calculations and experimental results allows for the evaluation of the single-particle structure near ^{78}Ni and suggests a single-particle nature for both the 5/2_{1}^{-} and 3/2_{1}^{-} states in ^{77}Cu, leading to doubly magic ^{78}Ni.

RESUMO

OBJECTIVES: The aim of the current study was to compare the clinical results of pediatric supracondylar humerus fracture cases requiring open reduction through medial approach with posterior approach. PATIENTS AND METHODS: Retrospective cohort of 67 cases of pediatric supracondylar fractures was reviewed. Thirty-three patients (20 males, 13 female, average age: 8.3 ± 3.131) were treated with medial approach were compared with 34 patients (19 males, 15 females, average age: 7.5 ± 3.146) treated with posterior exposure. Median follow-up period of the first group was 35.04 months (range: 17-76 months) and of the second group was 36.04 (range: 16-65 months). Radiological evaluation included Baumann angle, carrying angles, and lateral humero-capitellar angles. Functional and cosmetic evaluation was assessed with range-of-motion measurements and the criteria defined by Flynn et al. RESULTS: No differences between groups were noted regarding gender, age, and follow-up periods. Operative time was significantly shorter in medial approach group [60.0 ± 14.5 vs. 75.8 ± 17.6 min (P = 0.002)]. Radiological measurements (Baumann, humero-capitellar, and carrying angles) were also similar between groups. When evaluated patients according to Flynn's criteria, for medial group, 31 cases (93.9%) had good-perfect result regarding ROM loss, whereas for posterior group 33 cases (97%) had good-perfect result. Regarding carrying angle change and posterior group were slightly better than medial group (perfect result observed in 91.1% vs 81.8%, respectively). The differences did not show statistical significance. CONCLUSION: In the treatment of supracondylar humerus fractures in children, both surgical approaches revealed similar functional and radiological outcomes with shorter operative time when medial approach was utilized.

RESUMO

OBJECTIVE: To investigate the impact of hysteroscopic metroplasty on pregnancy outcome in women with complete or incomplete uterine septum (US) accompanying infertility. MATERIALS AND METHODS: Seventy-three patients who had hysteroscopic metroplasty for complete and incomplete US with primary and secondary infertility were reviewed. Obstetric outcomes (number of pregnancies, live births, and miscarriages) up to 36 months follow up period were investigated. RESULTS: Twenty-five patients in complete US and 28 patients in incomplete US became pregnant in 36 months follow up. Postoperative miscarriage rate was significantly lower in patients with complete US (p = 0.0001,p = 0.0001, respectively). The mean gestational week at the time of birth and mean birth weight of the in- fants were significantly lower in patients with complete US compared to the incomplete US cases (p = 0.026, p = 0.049, respectively). Postoperative pregnancy rate was significantly lower in incomplete US patients with primary infertility compared with secondary in- fertility (p = 0.037). CONCLUSION: Hysteroscopic metroplasty improves fertility and pregnancy performance. This improvement is more prominent in patients with complete US, and incomplete US patients with secondary infertility.

RESUMO

AIM: Method of femoral tunnel preparation in anterior cruciate ligament (ACL) reconstruction is controversial. In this study, we aimed to determine if there is any difference between the clinical outcomes of two most commonly used drilling techniques; which are conventional trans-tibial (TT) drilling of femoral tunnel and anatomic preparation of femoral tunnel through medial portal (MP), in patients who underwent ACL reconstruction. MATERIAL AND METHODS: One hundred and twenty-nine male patients who underwent ACL reconstruction between 2010 and 2012 were included in the study. Single-bundle reconstruction with a quadrupled autologous hamstring graft was performed in all patients. Femoral tunnel was drilled by the conventional TT technique in 58 patients (Group 1) and through MP in 71 patients (Group 2). Functional evaluation was made about 12 months postoperatively. Functional evaluation included the Lysholm Knee Scale, International Knee Documentation Committee Scoring (IKDC), and Tegner Activity Level Scale were used for assessment. The anteroposterior stability was assessed using KT-1000 arthrometer and the pivot shift test for assessment of rotational stability. RESULTS: Interval between injury and surgery was similar between two groups (median 8.0 vs. 10 weeks, for TT vs. MP, respectively). One hundred twenty-five patients attending the final follow-up examination (96.8%) were evaluated. The results of Lysholm, IKDC, and Tegner scales were found to be similar. According to KT-1000 arthrometer results, MP group revealed slightly better results than TT group. Regarding pivot shift, MP group showed significantly better stability than TT group (P < 0.001). CONCLUSION: The anatomical single-bundle femoral tunnel preparation in the reconstruction of the ACL seems as effective as the conventional technique in terms of functional stability in the midterm. The technique better preserved the rotational stability in non-professional athletes.

RESUMO

BACKGROUND AND AIM: In the management of hypertension (HT), maintaining the medication adherence with treatment is as important as starting treatment. Studies have shown that the majority of patients taking medication do not reach their target values. This study aimed to investigate the relationship between the patient medication adherence and blood pressure (BP) values and reflection to general well-being. MATERIAL AND METHODS: The study included 259 primary HT patients. The patients with BP measurements completed the Medication Adherence Self-Efficacy Scale-Short Form 13 and the World Health Organization-5 (WHO-5) well-being index. A Holter device was attached, and 24 h BP monitoring was completed. RESULTS: The mean points for medication adherence scale was 29.2 ± 10.3 (1-40) and mean WHO-5 points was 13.7 ± 4.6 (4-25) for patients. Clinical mean systolic BP was 140.0 ± 12.6 and diastolic 84.8 ± 9.0 mm Hg, while 24 h mean BP was systolic 119.5 ± 10.6 and diastolic 73.3 ± 8.1 mm Hg. While there was negative correlation between medication adherence scale scores and clinical systolic BP (r = -0.171; P = 0.006), there was no correlation with other BP readings. There was no correlation with the WHO-5 score and clinical readings, though there was a positive correlation between ambulatory mean systolic and diastolic BP (r = 0.141; P = 0.023 and r = 0.123; P = 0.049, respectively). There was positive correlation between the patient's medication adherence scores and the WHO-5 scores (r = 0.141; P = 0.023). CONCLUSION: When clinicians assess medication adherence of patients, they should benefit from objective BP measurements and scales. Subjective and objective findings are important while making clinical decision.
