Abstract

Introduction:
Hypothyroidism is often associated with weight gain. In this study, we assessed the correlation of anthropometric measurements and body compositions such as body mass index (BMI), waist circumference (WC), total fat, visceral fat, and triceps fold with different components of the thyroid profile.

Methods:
All the cases of clinical and subclinical hypothyroidism were evaluated. The anthropometric measurements were taken using skin calipers and the body composition was assessed using a Dexa scan. The blood samples were collected for the estimation of thyroid hormone levels. A statistical correlation was drawn between the various anthropometric measures and body composition with different components of thyroid profile.

Results:
The gender-wise comparison study revealed that BMI, total fat %, and visceral fat % were significantly higher in the female gender. Total fat and visceral fat have a direct significant association with BMI (P > 0.005). An increase in age is associated with a rise in the values of triiodothyronine (T3) and thyroxine (T4) (P > 0.05). A positive correlation between thyroid-stimulating hormone (TSH) levels and BMI (r = 0.294), total fat % (0.026), visceral fat % (r = 0.216), and triceps fold measurement (0.004). Conversely, a negative correlation was observed between TSH levels and WC (r = −0.178). There was a negative correlation observed between T4 levels and BMI (r = −0.327), visceral fat percentage (r = −0.152), and triceps fold measurements (r = −0.076). However, a positive correlation was found between T4 levels and WC (r = 0.174) and total fat percentage (r = 0.090). A negative correlation was observed between T3 levels and BMI (r = −0.108), while a positive correlation was observed between T3 levels and all other variables.

Conclusion:
Age and BMI, but not gender, were found to be significantly associated with thyroid profile. Among anthropometric measurements, the total fat percentage demonstrated a positive correlation with all thyroid hormones, suggesting that the total fat percentage may be a more accurate predictor of thyroid hormone levels than other anthropometric variables alone.

Abstract

Background:
Metastasis to regional cervical lymph nodes is an important prognostic factor for oral-cavity squamous cell carcinomas (OSCC). However, it is difficult to predict nodal metastasis in OSCC. The current study was done with an aim to find the association of various clinicopathological factors to the presence of cervical lymph node metastasis in OSCC.

Materials and Methods:
A retrospective analysis of hospital records from January 2020 to June 2023 was conducted in a tertiary care center. The records of 65 patients were included as per the inclusion criteria. The data were divided into two groups based on the presence or absence of neck nodal metastasis. Various factors such as tumor size, volume, depth of invasion (DOI), lymphovascular invasion, and perineural invasion were statistically compared between the study groups.

Results:
The oral tongue was the most common subsite (25, 38.5%), followed by buccal mucosa (18, 27.7%). The mean DOI in the group with cervical lymph node metastasis was 9.83 ± 4.83 mm, and it was significantly higher than the group without cervical lymph node metastasis (6.15 ± 4.20 mm, P = 0.004).

Conclusion:
DOI assessment is one of the most important preoperative assessments in the clinicoradiological assessment of OSCC cases. Further, it is recommended that in cases with DOI >5 mm, the intraoperative frozen section on the nodes dissected in elective neck dissection is done for further determination of the extent of neck dissection.

Abstract

Aim:
The aim of the study was to identify the prevalence of systemic diseases among patients referred to a newly established government periodontal specialist clinic and to analyze the association between the severity (staging) and the rate of progression (grading) of periodontitis with the presence of these systemic diseases.

Materials and Methods:
Records of all new patients within the first 5 years of the clinic’s operation were reviewed, and their periodontitis status was classified according to the 2017 World Workshop Classification system. The association between the severity of periodontitis and the presence of systemic diseases was analyzed using the Chi-square test, whereas Fisher’s exact test was used to determine the association between the rate of progression and the presence of systemic diseases.

Results:
A total of 489 dental records were reviewed. We found that 40.1% of our patients suffered from systemic diseases. The two most common systemic diseases were cardiovascular disease (CVD) (11.4%) and diabetes mellitus (9.4%). No significant association was found between the severity of periodontitis and the presence of systemic diseases (P = 0.376). However, we found a significant association between the rate of progression of periodontitis and systemic diseases (P = 0.004). There was also a significant association between the rate of progression of periodontitis and CVDs (P = 0.001).

Conclusion:
The rate of progression of periodontitis is significantly associated with the presence of systemic diseases and CVDs. This highlights that periodontitis is not a stand-alone disease. Instead, it reaches across a spectrum of other noncommunicable diseases. The collaboration between medical and dental practitioners can further improve the management of this group of patients.

ABSTRACT.
Lymphedema, hydrocele, and acute adenolymphangitis (ADL) are chronically disabling consequences in patients with lymphatic filariasis (LF). Provision of morbidity management and disability prevention and concurrent mass drug administration of anthelmintics are two pillars for elimination of LF. This study assessed the impact of strict hygiene protocols with or without doxycycline on the progression of filarial lymphedema. A randomized, placebo-controlled, double-blind trial was conducted in two regions in Tanzania. We enrolled 362 participants with lymphedema stages 1–3 assigned into three treatment groups of doxycycline 200 mg once daily, doxycycline 100 mg once daily, or matching placebo for 42 days in addition to hygiene measures. The participants were followed every 2 months for 2 years. Twenty-four months after treatment onset, 17.7% of participants displayed improved limb conditions, including 15/104 (14.4%) in the doxycycline 200 mg group, 16/105 (15.2%) in the doxycycline 100 mg group, and 25/107 (23.4%) in the placebo group. During the first 6 months after treatment, the number of participants experiencing an ADL attack was significantly lower in the doxycycline groups than in the placebo group. The study also found that hygiene was one of the factors associated with preventing the occurrence of acute attacks over the whole study period. Doxycycline 100 mg was a significant factor for the halt of progression (odds ratio: 0.53, P = 0.0239) when both legs if affected at baseline were considered. These findings emphasize the importance of practicing hygiene in reducing the occurrence of ADL attacks and the benefits of doxycycline with regards to acute attacks and halt of progression.
STODOLA-VIANELLO ITERATION METHOD FOR FREE TORSIONAL VIBRATION ANALYSIS OF MONOSYMMETRIC BOX-BEAM BRIDGES
Authors: IKE Charles Chinwuba 
Published: August 2024

Box-beam bridges are used in large spans and wider decks due to their high strength and greater torsional and flexural stiffness. They are usually prone to vibration due to moving vehicular traffic. Their eigenfrequency analysis is a crucial aspect of their design in order to ensure that the natural frequency is not close to the excitation frequency to avert resonance failures. The free torsional vibration equation is a fourth order partial differential equation (PDE) with variable parameters. For prismatic cross-sections, homogeneous and isotropic materials the governing PDE have constant parameters. This paper explores the Stodola-Vianello iteration method (SVIM) for solving the PDE for isotropic, homogeneous prismatic box-beams. Harmonic response is assumed, decoupling the PDE to two equations, one in terms of time and the second an ordinary differential equation (ODE) in terms of space coordinates. The Stodola-Vianello method is used by the method of four successive integrations to express the ODE as an algebraic iteration problem with four constants of integration. The four boundary conditions are used to solve for the four constants of integration, thus making the problem determinate. Application of the boundary conditions results in the full determination of the iteration equations. For simply supported boundaries studied in the work, a trigonometric buckling shape function that satisfies all the boundary conditions is employed in the SVIM formula to obtain the next bucking modal shape function. The requirement for convergence is then used to establish the characteristic buckling equation from which the eigenvalues are obtained. The solution to the characteristic buckling equation gave the exact mathematical expression for the natural torsional frequency at the nth vibration mode. The frequencies are determined for the first eight vibration modes and compared with previously obtained values. It was found that the natural frequencies are identical with previously found values of the exact natural frequencies. The natural frequency obtained is exact because it satisfies the PDE and the boundary conditions at all points in the domain.

Comparison Between Empirical Strategies for Predicting Endpoint Phosphorus Content in BOF Steelmaking Process
Authors: Chaves Diego Henrique de Souza , Duarte Iara Campolina Dias , Costa Junior Esly Ferreira da , Costa Andréa Oliveira Souza da 
Published: August 2024

Dephosphorization is a reaction of important role in steelmaking process, and the correct adequacy of endpoint phosphorus content would improve the quality and productivity of steel in basic oxygen furnace (BOF) processing. Aiming to meet the required steel specifications and reduce process time, two different empirical strategies were established for predicting the endpoint phosphorus content in BOF steelmaking process: linear regression and neural network. Eight variables that affect the endpoint phosphorus content (selected as output) were determined as the input variables of the models. The performances of predictions were evaluated simultaneously with the sensitivity analysis of the model to variations in the values of its input variables. Sensitivity analysis is essential as it reveals the impact of input variables on results, although it is often neglected due to its complexity and the need for multiple simulations. Integrating sensitivity analysis with prediction techniques allows for identifying key variables and making decisions. Both empirical models are suitable and reliable for decision making in the process and can be used as tools for predicting the endpoint phosphorus content, where the neural network has higher accuracy. The sensitivity analysis showed that the two variables that most affect the response of the empirical models were the percentage of oxygen volume of oxygen blown until the sub-lance in relation to the estimated total volume, and the phosphorus concentration in the sub-lance.

Objectives: Naples prognostic score (NPS) is a recently established score that measures inflammation and nutritional conditions. This score includes lymphocyte-to-monocyte ratio, neutrophil-to-lymphocyte ratio, total cholesterol levels, and serum albumin levels. Initial studies have shown that the NPS score has more prognostic value than other inflammatory parameters in some cancer diseases. Recently, the association of the NPS score with various cardiovascular diseases has started to be evaluated. The association between ischemia in myocardial perfusion scanning and the Naples score has not yet been investigated. In this study, we evaluated if the NPS may help predict ischemia in myocardial perfusion scanning.
Methods: This study included a total of 110 patients. All patients underwent myocardial perfusion scintigraphy (MPS) at the nuclear medicine department, with dipyridamole or adenosine administered as the pharmaceutical stressor. The subjects were divided into two groups according to the presence or absence of ischemia on gated single-photon emission computed tomography (SPECT) MPI. Laboratory values within the past month before MPS were obtained from digital records for both groups. The NPS was calculated for each group. Laboratory values and NPSs of the groups were compared.
Results: All individuals in the trial had gated SPECT MPI. The average age of individuals was 59.8±11.1 years, with 62 patients (56%) being male. Subjects were divided into two groups according to the presence or absence of ischemia on gated SPECT MPI. Table 1 displays the demographics of the whole study population. Based on the laboratory data (Table 2), there was no significant difference in the demographic features of the groups. The ischemia group had significantly higher levels of white blood cell count (cells/ μL), neutrophil count (cells/µL), hemoglobin (g/dL), CRP (mg/L), and NPS (8.6±2.2, 7.7±1.9, p=0.040; 5.0±2.1, 4.1±1.3, p=0.014; 12.6±1.7, 13.4±1.8, p=0.025; 8.2±2.0, 7.9±2.0, p=0.004; 2.6±1.0, 1.5). Other laboratory results did not differ across the groups.
Conclusion: Our findings indicated an association between NPS and the detection of ischemia in MPS. NPS is an independent variable for diagnosing myocardial ischemia in stable coronary artery disease patients.
The Effect of Perceived Stress on Quality of Life in Patients with Myocardial Infarction
Authors: Çoban İlkay , Yürügen Birsen 
Published: August 2024

Objectives: Myocardial infarction (MI) is a common heart disease with a high mortality rate. In patients with MI, factors such as social isolation, the presence of a previous MI, and the presence of diabetes mellitus in some patients can create stress in the patient. Perceived stress after MI may lead to an increase in the frequency of hospitalization, frequent cardiac problems, and difficulty in adapting to secondary prevention programs. Therefore, it is important to know the relationship between perceived stress and quality of life. This study aimed to determine the effect of perceived stress on quality of life in patients with MI.
Methods: The population of this descriptive and correlational study consisted of all patients diagnosed with MI (n=506) who applied to the adult outpatient clinic of a Hospital in Istanbul between January and June 2021. The sample of the study consisted of 300 patients who came to the polyclinic for examination at the time of the study, were over 18 years old, were diagnosed with MI, did not have any communication problems, and did not receive psychiatric treatment and agreed to participate in the study. Research data were collected using the survey technique, Perceived Stress Scale-14 (PSS-14), and TR MI Dimensional Assessment Scale.
Results: A moderate positive significant relationship was found between the PSS-14 and the TR MI Dimensional Assessment Scale (r=0.656; p<0.01). There was a negative significant relationship between the perceived stress level of patients diagnosed with MI and their quality of life levels, and as the patient’s quality of life increased, their perceived stress level decreased. 42.9% of the patients’ quality of life levels were affected by their perceived stress level.
Conclusion: In light of the data obtained from the study, it was determined that perceived stress had a negative impact on the quality of life in patients with MI, and as perceived stress increased, the patient’s quality of life decreased.
