Article on Osteoarthritis
Authors: Jaiswal Dhananjay Kumar
Published: January 2024

Osteoarthritis, a prevalent and debilitating joint disorder, gradually erodes cartilage—the protective cushion between bones—leading to pain, stiffness, and reduced joint mobility, primarily in weight-bearing joints. While age, genetics, and joint injuries are key contributors, the symptoms, starting with minor discomfort, escalate to pronounced pain and limited movement. Timely diagnosis, involving patient history, exams, and imaging, is vital. Treatment entails pain management, physical therapy, lifestyle adjustments, and, in extreme cases, joint replacement surgery. Ongoing research offers hope for improved therapies, emphasizing early intervention and holistic approaches for enhanced joint health. This article delves into the depths of osteoarthritis, unraveling its underlying mechanisms i.e. pathophysiology, risk factors, diagnostic approaches, and management strategies including latest advancement
Outcomes of TFN-Advanced™ Proximal Nail System (TFNA) for AO Type 31-A1/A2/A3 Intertrochanteric Fractures: A Retrospective Review of 100 Cases with Minimum 2-Year Follow-Up
Authors: Factor Shai
Published: January 2024

Purpose: Hip fractures are a growing concern for healthy systems worldwide. Several fixation modalities have been developed for the fixation of AO type 31-A1/A2/A3 fractures. The TFN-AdvancedTM Proximal Nail System (TFNA) is a novel fixation device that aims to build on success of previous generation nails. Currently, there is a paucity of literature regarding the outcomes of this implant. The aim of this study was to present our experience using the TFNA implant over a 2-year minimum follow-up. Methods: We retrospectively reviewed patients above the age of 65 who underwent closed reduction and internal fixation (CRIF) for AO type 31-A1/A2/A3 intertrochanteric fractures, with the TFNA nail between January 2017 and June 2018. The minimum follow-up time in our study was 2 years. Radiological evaluation was performed during follow up visits to evaluate for post-operative complications. Results: Following exclusions, the final study population consisted of 100 patients. The mean follow-up was 30.8 months (range 24–44, SD 5.1). During the follow-up period, 6% of the patients (n=6) experienced orthopedic complications. The rate of peri-prosthetic fracture in our study was 2% (n=2), the rate of peri-prosthetic infection was 2% (n=2) and the cut-out rate was 1% (n=1). No cases of mal-union or non-union were observed. Revisions were required in 4% of patients (n=4). Conclusion: The low rates of complications reported in our study support the implementation of TFN-A as a fixation device for AO type 31-A1/A2/A3 intertrochanteric fractures undergoing CRIF. Additional follow-up is required in the long-term.
Does Surgeon Experience Affect the Risk of Post-Op Complications for Patients Undergoing Fixation for Intertrochanteric Fractures
Authors: Factor Shai
Published: January 2024

Background: Intertrochanteric fractures compromise approximately one half of all hip fractures. Common complications following fixation of these fractures include cut-out, non-union and avascular necrosis (AVN). It is unclear what effect surgeon experience has on the risk of developing these complications following fracture fixation. The purpose of this study was to compare the post-surgical outcomes for patients treated with TFNA nail for intertrochanteric fractures between residents and fellow trained orthopedic surgeons. Methods: Data was retrieved from the medical records of patients that underwent closed reduction and internal fixation (CRIF) for type 31A1, 31A2 and 31A3 (AO classification) fractures of the proximal femur. All of the fractures were treated with the Trochanteric Fixation Nail Advanced (TFN-A) nail between January 2017 and June 2018. Surgery was performed by either a fellowship-trained trauma surgeon or a resident who had completed his third year of residency. Data such as the duration of surgery, decreased hemoglobin levels, together with data on other hospitalization characteristics and any intraoperative and postoperative complications were retrieved from the medical files. Results: The final study population consisted of 100 patients. Forty-nine patients were operated upon by a senior surgeon, while 51 were operated upon by a resident surgeon. No significant difference was noted between cohorts for the duration of surgery (p = 0.66), blood loss (p = 0.13), orthopedic complications (p = 1) or rates of re-operation (p = 0.35). Conclusion: Residents may perform CRIF for intertrochanteric fractures without placing patients at an increased risk for post-surgical complications.
Does the Method of Fixation Affect the Risk of Complications in Patients with Pauwels Type 3, Displaced Intracapsular Femoral Fractures
Authors: Factor Shai
Published: January 2024

Background: Patients with Pauwels type III displaced intracapsular femoral fractures (DICFF) are at a high risk of developing avascular necrosis (AVN) and non-union following closed reduction and internal fixation (CRIF). We compared the complications between the Targon femoral neck (TFN) plate and the cannulated cancellous screws (CCS). Methods: This retrospective study reviewed the records of 34 patients younger than 65 years of age who underwent CRIF of Pauwels type III DICFF from January 2007 to January 2018. Patients were evaluated for demographic data as well as the fixation method. Subsequent postoperative radiographs were obtained to assess the incidence of AVN and nonunion. Results: 34 patients were included in the study, of which, 18 (53%) and 16 (47%) were treated using TFN and CCS, respectively There were no significant differences observed between the CCS and TFN cohorts in terms of age (p = 0.90), gender (p = 0.27), time to surgery (p = 0.36), and duration of surgery (p = 0.99). The incidence of AVN and non-union did not significantly differ between the groups, with rates of 38.9% and 43.8%, respectively (p = 0.083) Conclusions: The type of fixation utilized, whether CCS or TFN, did not have a significant impact on the incidence of treatment failure in patients with Pauwels type III fractures treated via CRIF

Authors: Latheef Momin Bin
Published: January 2024

Background: Currently, the preferred implants for stable trochanteric fractures are the Proximal Femoral Nail and the Dynamic Hip Screw with Locking Side Plate. The Locking side plate has resolved many of the limitations associated with the standard DHS. Although numerous studies have compared the standard DHS and PFN, there is a scarcity of literature on the prevalence of IT fractures in the Indian population and comparison of Locking DHS and PFN in term of radiological union times. The purpose of this study is to assess and compare the effectiveness of both implants in stable intertrochanteric fractures. Methods: The objective of this study was to assess the prevalence of intertrochanteric fractures in the Indian population and compare the radiological outcomes of using Locking DHS and PFN for fixation in 40 patients who were admitted to SUT Academy of Medical Sciences between October 2019 and April 2021. Serial x-rays were used to evaluate the patients' progress, and regular follow-up was conducted to compare their outcomes. Results: All 40 fractures united. The time to union ranged from 16 to 30 weeks, with an average of 22.0 weeks in the DHS group and 19.40 weeks in the PFN group. %). 3 complications were noted. 2 in the DHS group, namely malunion and superficial infection and 1 delayed union in the PFN group. Conclusions: The DHS group relatively took more time to achieve union while the PFN group achieved union faster. However our finding was not statistically significant. Based on these findings, we can conclude that both the Proximal Femoral Nail and Dynamic Hip Screw with Locking Side Plate are similarly effective in treating stable intertrochanteric fractures.

There were still many students who had low self-efficacy and locus of control. Students feel insecure so they tend to depend on students who are smarter. This study aims to analyze the effect of self-efficacy and locus of control on student achievement in twelve grade accounting class at senior high school. This research uses a quantitative approach with descriptive methods. The sampling technique in this study is simple random sampling. The data analysis technique used is multiple linear regression analysis by testing the hypothesis using the t test and f test. The results of the study show that: (1) There is a positive and significant influence between self-efficacy and student achievement as evidenced by the t-count 3,633 > t-table 2,00575 at the 5% significance level.; (2) There is a positive and significant influence between locus of control  with student achievement indicated by t-count 6,037 > 2,00575 at the 5% significance level.; (3) There is a positive and significant influence between self-efficacy, locus of control together with student achievement indicated by R Square 0.828 and f count of 139.923 > f table with (df: 2; 53) a significant level of 5% which is equal to 3.17. Based on the results of the analysis it can be concluded that the variables of self-efficacy and locus of control both affect learning achievement, where students who have self-efficacy and locus of control which is good then it will be able to improve learning achievement.

Information technology (IT) is important to meet the needs of students with hearing disabilities in Indonesian special schools. The purpose of this study is to analyze the use and opinion of IT for communication and learning of students with hearing impairment in hearing impairment schools. IT in this study includes information devices such as mobile phones, smartphones, and tablets. This study used a stratified random sampling method to register the participants. Data were collected from 56 students with hearing loss using a self-administered questionnaire. The results found that most of these students knew about chat applications, for example, Whatsapp, Facebook, Instagram, and face-to-face conversation applications. Furthermore, most of these students contact people with hearing problems by sending messages via Facebook, Line apps, and face-to-face. The main reason why they use IT is for convenience and general conversation. A study of opinions on the use of IT by students with hearing impairment found that most of them agreed that IT devices contributed to their participation in various activities, including conversations with their relatives and friends on social networks.

The low student mathematics learning outcomes are caused by several factors such as students' anxiety, learning discipline, and learning motivation. The study was aimed to analyze the effect of students’ anxiety, learning discipline, and learning motivation towards students’ mathematic learning outcomes.  The research design was in the form of ex post-facto by involving 235 vocational high school students. They were selected by using proportional random sampling. The data were obtained by conducting test and non-test technique. The test was conducted to obtain the students’ learning outcomes meanwhile the questionnaire was distributed to the students to gather their anxiety, learning discipline, and learning motivation. The research instruments were test and questionnaire. The obtained data were analysed through structural equation modelling (SEM). The result showed that;  1) there  was a positive effect of learning discipline on students’ mathematic learning , 2) there was a negative effect of students’ anxiety on students’ learning discipline, 3) there  was a direct negative influence contributed by students’ anxiety towards students’ learning motivation, 4) there was a direct positive effect of students’ learning motivation on students’ learning discipline, 5) there was a direct positive effect of learning motivation towards students’ mathematic learning outcomes, 6) there was a direct negative effect of anxiety on students’ learning discipline, and 7) there was indirect positive effect of learning motivation on students’ mathematic learning outcomes through learning discipline.
Polymorphism of xenobiotic biotransformation enzyme genes and their role in early pregnancy loss

Considering the progressive decrease in the number of women of fertile age, as well as children and adolescents, the primary medical and social task at the present stage is to preserve the reproductive health and life of women, preserving every desired pregnancy. The concept of demographic policy of the Russian Federation for the period until 2025 defines the global national goals, i.e. to increase the total fertility rate by 1.5 times, to reduce maternal and infant mortality by at least 2 times, and to improve the reproductive health of women, children and adolescents. Today every fifth desirable pregnancy ends in early loss, and the rate of miscarriage does not tend to decrease and, in fact, increases every year. Carriage of susceptibility or candidate genes can alter the course of biochemical processes in women and cause early pregnancy losses. According to the literature, the cytochrome P-450 gene (CYP1A1, CYP1B1), xenobiotic detoxification genes (GSTT1, GSTM1, GSTP1) and many others are recognized as candidate genes (genetic markers) associated with reproductive losses. Adverse pregnancy outcome is usually multifactorial; in turn, the combination of polymorphic variants of different candidate genes can increase the risk of early losses. A detailed study of the role of candidate genes with clarity and confirmation of the interest of candidate genes in the development of pregnancy loss is undeniable. In this regard, the interest of many researchers in studying the polymorphism of genes of the xenobiotic biotransformation enzyme system as one of the causal factors of pregnancy failure is understandable. The study of this group of genes is of particular relevance in regions with developed industry and high anthropogenic load. The article is devoted to the analysis of the existing data of foreign and domestic literature sources concerning the relationship between polymorphism of xenobiotic biotransformation system genes and reproductive losses.

Aim. To study of serum magnesium in women with a history of adverse pregnancy outcomes.

Materials and Methods. 74 women of child-bearing age, subject to voluntary informed consent, participated in a prospective cohort study. The main group (n = 31) included non-pregnant women who had a history of unfavorable gestation outcomes: premature birth, spontaneous miscarriage, habitual miscarriage, undeveloped pregnancy. The comparison group (n = 43) consisted of non-pregnant women with a history of two or more urgent deliveries. In all women, in preparation for pregnancy, the content of serum magnesium was determined by colorimetric method with xylidine blue.

Results. 77.6% of women with a burdened obstetric history of miscarriage (the main group) had various menstrual cycle disorders (FIGO, 2018). When analyzing the levels of magnesium in the blood serum of the examined women, it turned out that the obtained indicators in women of both groups corresponded to the established reference range of normal values of serum magnesium levels. At the same time, in the women of the main group, the average magnesium content in the blood serum was significantly lower and was closer to the lower limit of the range of normal values, and in the comparison group – in the middle of the range of normal values: 0.719 (0.672-0.767) mmol/l and 0.844 (0.778-0.922) mmol/l, respectively, p<0.001.

The optimal threshold value of the serum magnesium index in the study was 0.796 mmol/l with the sensitivity and specificity of the proposed prognostic model of 80.6% and 81.4%, respectively.

Conclusion. Determination of the level of magnesium in the blood serum of women at the stage of pre-pregnancy counseling is of particular importance. Despite the fact that all the examined women had serum magnesium levels within the range of its normal values, significantly lower serum magnesium levels were found in women with adverse pregnancy outcomes in the anamnesis, which necessitates prescribing magnesium-containing medications to such patients at the stage of pregnancy planning. For the prevention of miscarriage within the framework of preconception preparation with serum magnesium values ≤0.796 mmol/l, the intake of organic magnesium salts is recommended.
