BACKGROUND:In this study, we evaluated to the relationship between the type of accessory navicular bone (ANB) and radiological parameters of foot in patients with bilateral ANB of different types. METHODS:Patients with bilateral ANB of different types participated in this study, from May 2019 to April 2020. Patient data, including age, sex, body mass index (BMI), and presence of symptoms were obtained. We aimed to compare the radiological parameters of both the feet for evaluate the differences from one another in patients with bilateral ANB of different types (one side type 1 and contralateral side type 2) because the foot angles may differ in each person. Seven radiographic parameters were measured, including calcaneal pitch angle, talocalcaneal angle, tibiocalcaneal angle, naviculocuboid overlap, talonavicular coverage angle, anteroposterior talo-first metatarsal angle, and the lateral talo-first metatarsal angle, which evaluated hindfoot, midfoot, and forefoot alignment. RESULTS: Twenty patients (13 women and 7 men) with a mean age (and standard deviation) of 38.5 {plus minus} 12.3 years were included in the study. The patients had a mean height of 168.1 {plus minus} 7.1 cm, a mean weight of 77.2 {plus minus} 10.5 kg, and a mean BMI of 27.4 {plus minus} 4.3 kg/m2. There was no significant difference between type 1 and type 2 in all radiological parameters. There was no significant correlation between radiological parameters and age, BMI, or the presence of symptoms. CONCLUSIONS: We found that the type of ANB had no effect on the radiological measurements of the foot in which we evaluate the parameters patients with bilateral ANB of different types. Additionally, age, BMI, and the presence of symptoms, also demonstrated no correlation with the radiological parameters of the foot.

Background: This study aimed to compare the radiologic parameters of both feet in patients with unilateral accessory navicular bone (ANB) and evaluate the differences from one another. Methods: Forty-one patients with unilateral ANB volunteered to participate in this study from August 2019 to January 2020. Patient data, including age, sex, body mass index (BMI), type of ANB, and presence of symptoms were obtained. Group 1 comprised 23 patients with asymptomatic unilateral ANB, and group 2 comprised 18 patients with symptomatic unilateral ANB. Seven radiologic parameters were evaluated assessing hindfoot, midfoot, and forefoot alignment—calcaneal pitch angle, talocalcaneal angle, tibiocalcaneal angle, naviculocuboid overlap (NCO), talonavicular coverage angle (TNCA), anteroposterior talo–first metatarsal angle, and lateral talo–first metatarsal angle. Results: The mean age of patients was 40.1 years in group 1 and 42.6 years in group 2. Mean BMI was 25.2 in group 1 and 26.6 in group 2. No significant differences were noted in the radiologic parameters between the ANB and contralateral sides in all patients. The radiologic parameters of both feet in symptomatic and asymptomatic patients were not significantly different. No significant differences were noted between the affected sides of type 1 and 2 ANB and contralateral sides in terms of the radiologic parameters. BMI was significantly correlated with NCO and TNCA. Conclusion: This study demonstrated that the presence of an accessory navicular bone did not affect radiologic parameters of the foot. Radiologic parameters of both feet in symptomatic patients were not significantly different. Level of Evidence: Level III, diagnostic, comparative study.

Purpose The variables causing symptomatic accessory navicular are largely unknown and may inform management of symptomatic patients. The purpose of this study was to examine patient specific factors associated with the development of accessory navicular symptoms. Methods A total of 71 patients with clinical and radiographic evidence of accessory navicular syndrome were evaluated. Patient gender, race, date of birth, date of earliest foot complaint and laterality were recorded. Treatment was defined as conservative versus surgical. Skeletal maturity was assessed based on calcaneal ossification, accessory navicular subtype and the presence of pes planus based on talo-first metatarsal angle were assessed. Results Female patients comprised 72% of the subjects and trended towards symptoms at younger ages than male patients (p = 0.06), while no significant difference in presentation age was appreciated between male and female patients. Skeletal maturity was significantly associated with earlier complaints and age at presentation but was not associated with increased need for surgical management. Patients with pes planus were significantly more likely to undergo operative management. Accessory navicular subtype was significantly correlated with skeletal maturity. Conclusion Female patients were more likely to report symptoms and present with symptomatic accessory navicular. The stage of skeletal maturity is not a predictor of future surgical management but patients with a higher first-metatarsal angle were more likely to require surgery. The correlation between accessory navicular subtype and skeletal maturity suggests that Type II ossicles are likely to develop into Type III over time. Radiographic evaluation of the accessory navicular may lend prognostic data on the necessity of future surgical intervention. Level of Evidence IV, Case Series

The environment can affect people’s health by relieving stress, and rural landscape as a special environment might influence human’s stress relief. This study takes different types of rural landscapes as the research object to explore their impact on stress levels, which are shown by photos. As an independent variable, the rural landscape is divided into three levels: Type 1 (natural landscape), type 2 (productive landscape), and type 3 (artificial landscape). Seventy-three subjects were randomly assigned to each type of rural landscape. Salivary cortisol, blood pressure, heart rate, and a subjective rating state scale (brief profile of mood states, BPOMS) were used as indicators of stress. At the same time, the influence of preference and familiarity on the stress relieving effect was also discussed. A paired t-test and one-way analysis of variance (ANOVA) were used as the main statistical methods. In the results of t-test for pre-posttest, significant difference was observed in high blood pressure, heart rate, and total mood disturbance (TMD) of type 1 and type 2, and the high and low blood pressure of type 3; ANOVA analysis revealed that for the difference of pre-posttest, significant difference was observed in the TMD value among the three types; except for type 3, blood pressure, heart rate, and BPOMS values were significantly affected by preference and familiarity. The conclusions include the following: The three types of rural landscapes have a positive effect on relieving stress; the productive landscape has the best effect on relieving stress; and users’ landscape preferences and familiarity with the environment can affect the effect of stress relief in rural landscapes.

The assessment and dynamic control over students’ status is a very important task. It allows timely detection of prenosological status prior to pathology and health maintenance in students. The objective of the paper is to assess the adaptive abilities of the body, to analyze changes in heart rate variability indicators in students with various types of autonomic regulation, to identify prenosological status and precursory pathological symptoms. Materials and Methods. The study enrolled 302 students from India, aged 21.54±1.43. Programming complex «Psychophysiologist» was used to register the main HRV parameters within 5 minutes. Health status was evaluated according to the index of functional changes and the scale of functional states. Results. N.I. Shlyk (2009) distinguished two groups of students with different types of autonomic regulation: type 1 (53 %) with moderate and type 2 (5 %) with marked characteristics of central regulation profile, type 3 (35 %) with moderate and type 4 (7 %) with marked characteristics of autonomous regulation profile. Main parameters of HRV and adaptation potential were defined for each student.All the parameters characterized functional and health status. Conclusions. It was shown that 82 % of trial subjects (type 1), 53 % (type 2), 94 % (type 3) and 95 % (type 4) demonstrated satisfactory adaptation and their physiological processes were at an optimal level. 18 % of students (type 1) demonstrated reduced adaptive abilities of the body. Moreover, they were under moderate stress. 47 % of subjects (type 2) were also under a significant stress, which was proven by excessively high SI, low SDNN and TP, and an increased index of functional changes. 5 % of students (type 4) revealed dysfunctional characteristics in the heart rhythm, peculiar to pathology. Keywords: foreign students, heart rate variability, types of autonomic regulation, adaptation potential, functional status.

ABSTRACT Plio?-Pleistocene outcrops located at the southwestern edge of the Guadalquivir Basin in the area of Lepe (Huelva, Spain) provide an interesting example for studying the contemporaneity of traces with the rocks that contain them. Two different types of cells compatible with the ichnogenera Celliforma (Type 1) and Palmiraichnus (Type 2) were found in these outcrops. Their walls were constructed with the same material as the matrix and our first research in the area showed no extant bees producing them suggesting that they were coeval with the trace-bearing rocks. The case of the “Palmiraichnus-like” Type 2 cells was misleading because of its similarity with Palmiraichnus described from the region in the Canary Islands and Balearic Archipelago (Spain). Two determining features were vital in clarifying this first appearance. In the Palmiraichnus-like cells we found remains of a larval cocoon in one cell that could be dated by C14, giving a modern age. In the Celliforma-like cells more field research in the area allow us to observe extant bees nesting in these rocks in autumn. Ichnological literature show a few cases of asynchronies involving extant traces found mostly in Paleozoic and Mesozoic rocks. In contrast, the case presented herein indicates the time gap between the bearing rocks and the Lepe traces was shorter (ca. 12 ky–2.6 My), enhancing the similarity of traces and rocks and thus their potential coevalness. This case may serve as a warning about other potential examples in the fossil record in which relatively short asynchronies between traces and paleosols exist.

CNNM2 (Cystathionine-β-synthase-pair Domain Divalent Metal Cation Transport Mediator 2) pathogenic variants have been reported to cause hypomagnesemia, epilepsy, and intellectual disability/developmental delay (ID/DD). We identified two new cases with CNNM2 novel de novo pathogenic variants, c.814T>C and c.976G>C. They both presented with infantile-onset epilepsy with DD and hypomagnesemia refractory to magnesium supplementation. To date, 21 cases with CNNM2-related disorders have been reported. We combined all 23 cases to analyze the features of CNNM2-related disorders. The phenotypes can be classified into three types: type 1, autosomal dominant (AD) inherited simple hypomagnesemia; type 2, AD inherited hypomagnesemia with epilepsy and ID/DD; and type 3, autosomal recessive (AR) inherited hypomagnesemia with epilepsy and ID/DD. All five type 1 cases had no epilepsy or ID/DD; they all had hypomagnesemia, and three of them presented with symptoms secondary to hypomagnesemia. Fifteen type 2 patients could have ID/DD and seizures, which can be controlled with antiseizure medications (ASMs); their variations clustered in the DUF21 domain of CNNM2. All three type 3 patients had seizures from 1 to 6 days after birth; the seizures were refractory, and 1/3 had status epilepticus; ID/DD in these AR-inherited cases was more severe than that of AD-inherited cases; they all had abnormalities of brain magnetic resonance imaging (MRI). Except for one patient whose serum magnesium was the lower limit of normal, others had definite hypomagnesemia. Hypomagnesemia could be improved after magnesium supplement but could not return to the normal level. Variations in the CBS2 domain may be related to lower serum magnesium. However, there was no significant difference in the level of serum magnesium among the patients with three different types of CNNM2-related disorders. The severity of different phenotypes was therefore not explained by decreased serum magnesium. We expanded the spectrum of CNNM2 variants and classified the phenotypes of CNNM2-related disorders into three types. We found that DUF21 domain variations were most associated with CNNM2-related central nervous system phenotypes, whereas hypomagnesemia was more pronounced in patients with CBS2 domain variations, and AR-inherited CNNM2-related disorders had the most severe phenotype. These results provide important clues for further functional studies of CNNM2 and provide basic foundations for more accurate genetic counseling.

Background. It is well known that intramammary arterial calcifications diagnosed by mammography as a part of generalized diabetic macroangiopathy may be an indirect sign of diabetes mellitus. Hence, the aim of this study was to determine the incidence of intramammary arterial calcifications, the patient?s age when the calcifications occur, as well as to observe the influence of diabetic polineuropathy, type, and the duration of diabetes on the onset of calcifications, in comparison with nondiabetic women. Methods. Mammographic findings of 113 diabetic female patients (21 with type 1 diabetes and 92 with type 2), as well as of 208 nondiabetic women (the control group) were analyzed in the prospective study. The data about the type of diabetes, its duration, and polineuropathy were obtained using the questionnaire. Statistical differences were determined by Mann-Whitney test. Results. Intramammary arterial calcifications were identified in 33.3% of the women with type 1 diabetes, in 40.2% with type 2, and in 8.2% of the women from the control group, respectively. The differences comparing the women with type 1, as well as type 2 diabetes and the controls were statistically significant (p=0.0001). Women with intramammary arterial calcifications and type 1 diabetes were younger comparing to the control group (median age 52 years, comparing to 67 years of age, p=0.001), while there was no statistically significant difference in age between the women with calcifications and type 2 diabetes (61 years of age) in relation to the control group (p=0.176). The incidence of polineuropathy in diabetic women was higher in the group with intramammary arterial calcifications (52.3%) in comparison to the group without calcifications (26.1%), (p=0.005). The association between intramammary arterial calcifications and the duration of diabetes was not found. Conclusion. The obtained results supported the theory that intramammary arterial calcifications, detected by mammography could serve as markers of co-existing diabetes mellitus and therefore should be specified in radiologic report in case of their early development.

Diabetes mellitus is a succession of different types of disorders in metabolism that are characterized by causing a high rate of blood sugar. Because it is a disease with genetic factors type 1 diabetes has as main risk factor heredity, while type 2 diabetes besides these factors, includes obesity, high blood pressure, poor food education and advancing age. This study aims to show the number of cases of type 1 and 2 diabetes diagnosed in Amapá with the variables gender, age group, sedentary lifestyle, overweight, smoking, between 2007 and 2012. The data for the research were taken from the computer department of SUS, DATASUS (http://datasus.saude.gov.br). Type 1 and 2 diabetes mellitus (DM1 and DM2) are diseases that are tied to disturbances in production or in the efficient use of insulin. Smoking, as well as sedentary lifestyle and overweight are important risk factors for the development of DM2. Type 2 diabetes mellitus provides the development of various organic nerve lesions. In addition, DM2, through its chronicity, enables the development of retinopathies, nephropathies and other conditions negative to the individual’s health.

Aims. To assess differences in blood formed elements aggregation activity in patients with type 1 (T1) and type 2 (T2) diabetes mellitus(DM). Materials and methods. We studied blood samples from 88 patients with T1 and T2 DM. Platelet aggregation activity was assessed bymeans of ?Biola? aggregometer; we also determined platelet-lymphocyte and leucocyte-erythrocyte adhesion intensity. Results. We show that spontaneous platelet aggregation is markedly increased in patients with T1DM but remains normal or slightlyelevated in case of T2DM. In blood from patients with T2DM platelet aggregation in response to ADP, epinephrine, ristomycineand contact with collagen was generally increased, whereas in T1DM we often observed its secondary reduction. Data on plateletlymphocyteadhesion in T1DM is controversial, but in T2DM this process seems to be significantly suppressed. Quantity of leucocyteerythrocyteaggregates was sharply increased in both T1DM and T2DM. Conclusion. We've determined significant difference in blood formed elements aggregation activity between patients with T1 and T2 DM.

Summary Objectives The aim of this study was to evaluate characteristics of patients with unilateral transmigration of a mandibular canine in the largest study group presented until now. Materials and methods The study group consisted of 93 patients with unilateral transmigration of mandibular canine; the control group included 85 non-affected patients. Type of transmigration, status of deciduous and permanent canines, prevalence of missing teeth, class of occlusion, and space conditions were assessed to draw comparisons between groups. Results In this study, 64.5 per cent patients presented type 1 of transmigration; types 2, 3, 4, and 5 were present in, respectively, 23.7, 5.4, 4.3, and 2.1 per cent patients. There was a clear, statistically significant difference (P < 0.0001) between the mean crown and apex migration and angulation for the three groups of canines (transmigrated, contralateral, and control), whereas no differences were observed for the total number of permanent teeth present. In the study group, 73.1 per cent patients retained their primary canine on the affected side and 18.3 per cent on the contralateral side; in the control group, 22.3 per cent subjects had at least one primary canine. There was a statistically significant difference in the distribution of types of malocclusion between the study and the control groups. Conclusions Transmigration of mandibular canine was associated with the presence of retained primary canine on the affected side, higher mesial tilting of contralateral mandibular canine when compared to the canines in the control group. Additionally, higher prevalence of Angle’s Class I occlusion in patients with canine transmigration was recorded.
