Happiness and social appearance anxiety in overweight young girls

OBJECTIVE

This research was conducted to determine the relationship between social appearance anxiety and happiness in overweight young girls.

SUBJECTS AND METHODS

This is a correlational descriptive study and the study sample included 343 overweight young female students from a university in eastern Turkey. A Personal Information Form, the Oxford Happiness Questionnaire-Short Form (OHQ-SF), and the Social Appearance Anxiety Scale (SAAS) were used for data collection. Descriptive statistics (percentage, mean, standard deviation), independent-samples t-test, analysis of variance, and correlation and regression analyses were used in data analysis.

RESULTS

The mean age of the participants was 21.55 ± 3.03 years. About a third of the participants (30.6%) was composed by year 3 university students, 60.6% had an income level equal to their expenditure level, and 50.7% was residing in the city center. The OHQ-SF mean total score of the participants was 17.03 ± 5.86, and the SAAS mean total score was 43.36 ± 17.07. There was a moderate negative correlation between the mean scores of the OHQ-SF and the SAAS (r: -.547, p<0.001). Social appearance anxiety explained 30% of happiness in young girls participating in the study (β: -.547, p<0.001).

CONCLUSIONS

Happiness in young girls was effective on social appearance anxiety. Health professionals may also evaluate the level of happiness in the care and counseling services they provide to young girls during extraordinary circumstances such as the COVID-19 pandemic.

Melatonin Modulates the Immune System Response and Inflammation in Diabetic Rats Experimentally-Induced by Alloxan

Diabetes mellitus (DM) is a metabolic disease, which causes an increase in the proinflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukin 1β (IL-1β), and also proliferation of monocyte chemotactic protein. In the present study, the potential effects of melatonin on proinflammatory cytokines, hematological values, and lymphoid tissues were investigated in diabetic rats. In the study, 36 male rats were randomly divided into 4 groups as follows: Control, Mel (melatonin), DM, and DM-Mel. For 15 days, an isotonic saline solution was given to the Control and DM groups; melatonin was administered to the Mel and DM-Mel groups intraperitoneally. At the end of the study, all animals were sacrificed by drawing the blood from their hearts under deep anesthesia. Samples of the spleen, thymus, and lymph nodes were fixed in 10% formaldehyde for histologic analysis. Increases in proinflammatory serum cytokine concentrations, mast cells, and total white blood cell counts as well as tissue destruction in the lymphoid organs were determined in the DM group via biochemical, hematological, and histologic analyses. However, the findings for the DM-Mel group revealed decreases in serum IL-1β concentration and mast cell densities, and destructions in lymphoid tissues by the melatonin administration. The present study suggests that melatonin treatment may control immune system regulation and inhibit the production of proinflammatory cytokines and tissue mast cell accumulation by preventing the destruction of lymphoid organs in the diabetic process.

Effect of mycophenolate mofetil on cerulein-induced acute pancreatitis

AIM

The aim of this study was to determine the effects of mycophenolate mofetil (MMF) on acute pancreatitis with evaluation of biochemical and histopathological findings.

MATERIALS AND METHODS

Cerulein was administered to induce acute pancreatitis in rats. Three groups of 10 rats each were formed. Animals in group 1 received physiologic saline solution. In group 2 animals received MMF at a dose of 14 mg/kg and group 3 had double doses of MMF. Alanine aminostransferase, aspartate aminotransferase (AST), amylase and bilirubin levels were assessed. Pancreatic tissues were evaluated under light microscopy for the presence of edema, acinar necrosis, hemorrhage, inflammation and perivascular infiltration.

RESULTS

Amylase, serum AST, edema and inflammatory infiltration levels differed between groups (amylase: p = 0.0001, serum AST: p = 0.001, edema: p = 0.0001 and inflammatory infiltration: p = 0.002), group 1 showing the highest amylase, serum AST and edema levels. The lowest levels of edema were found in group 3.

CONCLUSION

In an experimental pancreatitis model in rats, MMF proved to exert a beneficial effect on biochemical and histopathological parameters.

Differences in hepatitis A seroprevalence among geographical regions in Turkey: a need for regional vaccination recommendations

Hepatitis A is a worldwide vaccine-preventable infection. Recommendation of vaccination depends on the endemicity of the disease. The World Health Organization recommends universal hepatitis A vaccination in intermediate areas; however, there is no need of mass vaccination in high and low endemicity regions. Therefore, most of the countries are using a vaccination policy according to the endemicity characteristic representing the whole of the country. The endemicity of this infection varies due to sanitary and hygiene conditions and socioeconomic differences among the countries and in various regions of the same country. A sample of 1173 persons between the age of 0 and 91 years from nine randomly selected medical centres from five different geographical centres of Turkey were tested for the level of anti-hepatitis A virus (anti-HAV) immunoglobulin-G antibodies using an enzyme-linked immunosorbent assay. The overall prevalence of anti-HAV antibodies was 64.4% (1142/1173). While the rate of sero-positivity was over 80% in the 5-9 age group and more than 90% after 14 years of age in south-eastern and eastern regions, it was lower than 50% at the age of 5-9 years in central and western regions and remains under 80% in those areas. We conclude that the differences observed in HAV sero-positivity among various geographical regions in Turkey support a universal HAV immunization policy for children currently living in regions of intermediate endemicity.

Small bowel perforation due to blunt trauma directly to the inguinal region: A case report

We report on a patient with intestinal perforation caused by direct blunt trauma to the inguinal region. The patient had been previously diagnosed with an inguinal hernia. The perforation was managed surgically, and he subsequently underwent hernia repair. In our opinion, intestinal perforation caused by inguinal region trauma in patients with inguinal hernias is a rare and unfortunate situation but one that reveals the importance of inguinal hernia repair.

Excision and marsupialization versus sinus excision for the treatment of limited chronic pilonidal disease: a prospective, randomized trial

The treatment techniques for pilonidal disease are either associated with high recurrence rates or complex procedures. This prospective randomized study compared the outcome of excision and marsupialization technique with sinus excision technique. A total of 40 consecutive patients with limited, chronic pilonidal sinus disease were operated with either excision and marsupialization technique (Group 1, n=20) or sinus excision technique (Group 2, n=20). The demographics, perioperative data, complications and recurrences were recorded. Patient satisfaction was evaluated with a specific questionnaire 16-18 weeks after surgery. Demographic data, preoperative symptoms and the acute disease history were similar between the groups. Operation time, hospital stay and work-off periods were significantly shorter and the number of out-patient procedures was significantly more in Group 2. Although satisfaction scores were similar between the groups, the patients who had no complaint, were "completely satisfied" or would "absolutely recommend the operative technique to other patients" were significantly more in Group 2. In conclusion, the sinus excision technique requires a shorter operation time, hospital stay and work-off period than excision and marsupialization in the treatment of limited, chronic pilonidal disease. The sinus excision technique can be performed as an out-patient procedure in most cases, and seems to be associated with better patient satisfaction.

Effects of adding alfentanil or atracurium to lidocaine solution for intravenous regional anaesthesia

BACKGROUND AND OBJECTIVE

The addition of alfentanil or atracurium to lidocaine solution for intravenous regional anaesthesia of the arm may have advantages with respect to improved muscle relaxation and better analgesia. The study investigates these possibilities.

METHODS

We investigated 33 patients. Plain lidocaine solution was administered to Group 1 (n = 11). Alfentanil (0.5 mg) and atracurium (3 mg) were added to the lidocaine solution in Groups 2 (n = 11) and 3 (n = 11), respectively. The onset of sensory and motor block, intra- and postoperative pain scores, and the duration of postoperative analgesia were evaluated.

RESULTS

There was a significant difference in the speed of the onset of sensory block in the hand, but not at the tourniquet site. The onset of the motor block, intra- and postoperative pain scores, and the duration of postoperative analgesia were similar in all groups.

CONCLUSIONS

No clinical benefits of adding alfentanil or atracurium to lidocaine solution for intravenous regional anaesthesia of the arm could be shown.

The effectiveness of systemic antibiotics in preventing postoperative, intraabdominal adhesions in an animal model

OBJECTIVE

Postoperative intraabdominal adhesions can be prevented by antibiotic lavage. We assessed whether systemic antibiotics could prevent adhesion formation in a rat model.

METHODS

Cecal abrasion was performed in the peritoneal cavities of 40 Wistar albino rats. Twenty rats were treated with a 5-day course of cefepim and metronidazole; the remaining animals were given saline injections. The animals were sacrificed 14 days after surgery. Adhesion severity scores and histopathologic findings were compared.

RESULTS

The median adhesion severity score was 2 (0-3) in the antibiotic group and 2.5 (1-4) in the controls (P = 0.03). In tissue specimens from controls, the adhesions were marked by mature collagen bundles. In treated rats, the adhesions were immature, characterized by early inflammatory cells, less collagen formation, and no collagen bundles.

CONCLUSIONS

Postoperative systemic antibiotics slow adhesion formation and reduce the severity of the adhesions.

[Evaluation of 572 cases of blunt and penetrating thoracic trauma]

We retrospectively evaluated 572 patients with thoracic trauma from total of 2163 trauma patients who admitted to 2nd General Surgery Emergency Service of Kartal Education and Research Hospital from January 1997 to February 2000. 501 of the patients (87.5%) were male and 71 (12.5%) were female. The range of ages 2-84 and mean age was 32.2. 337 (59%) patients had blunt and 235 (41%) had penetrating thoracic trauma. While traffic accidents (72%) were determined as the most common ethiological factor for blunt thoracic trauma, penetrating and cutting instruments injuries (82%) were the most common factor for penetrating thoracic trauma. Accompanying trauma were observed in 37.5% of cases. 332 (58%) tube thoracostomy, 185 (32.5%) conservative treatment, 41 (7.1%) thoracotomy 14 (2.4%) mechanical ventilation were carried out. The rates of mortality were 6.8% and of morbidity 3.3%. Early diagnosis and immediate appropriate treatment in thoracic trauma increases the survival.

Conformational dynamics of subtilisin-chymotrypsin inhibitor 2 complex by coarse-grained simulations

An off-lattice dynamic Monte Carlo (MC) method is used to investigate the conformational dynamics of chymotrypsin inhibitor 2 (CI2) and subtilisin in both free and complex forms over two time windows, referring to short and long time scales. The conformational dynamics of backbone bonds analysed from several independent trajectories reveal that: Both the inhibitor and the enzyme are restricted in their bond rotations, excluding a few bonds, upon binding; the effect being greatest for the loop regions, and for the inhibitor. A cooperativity in the near-neighbor bond rotations are observed on both time scales, whereas the cooperative rotations of the bonds far along the sequence appear only in the long time window, and the latter time window is where most of the interactions between the inhibitor and the enzyme are observed. Upon binding, the cooperatively rotating parts of the inhibitor and the enzyme are readjusted compared to their free forms, and new correlations appear. The binding loop, although it is the closest contact region, is not the only part of the inhibitor involved in the interactions with the enzyme. Loops 3 and 8 and the helices F and G in bound enzyme and the binding loop of the inhibitor contribute at the most to the collective motions of whole structure on the slow time scale and are apparently important for enzyme-inhibitor interactions and function. The results in general provide evidence for the contribution of the loops with cooperative motions to the extensive communication network of the complex.

[Evaluation of patients wounded in the 17 August 1999 Marmara earthquake]

This study describes the experience of Kartal Research and Training Hospital in the Marmara Earthquake. We reviewed medical records of 698 patients admitted to our hospital in a 30 days' period after the earthquake and analysed the types of injuries, treatment, morbidity and mortality rates. The hospitalized 273 patients were grouped according to the major injury; patients with crush syndrome were analysed separately. The most frequent injuries were crush injury (23.1%), extremity fractures (16.8%) and pelvis and spine injuries (16.1%). More than two system injuries were seen most frequently in the abdominal injury (45.5%), crush injury (24.4%), and pelvis and spine injury (27.3%) groups (p < 0.05). Overall mortality rate was 7.3%. The highest mortality rates were seen in the abdominal injury (27.3%) and crush injury (20%) groups (p < 0.05). 61.9% of the patients with crush syndrome underwent fasciotomy due to the compartment syndrome; hemodialysis was performed in 31 patients. The most serious problem with earthquake is organization in the earthquake area, between hospitals and in hospitals. Crush injury is the major injury seen earthquakes. Early diagnosis and proper treatment should be done to improve survival.

Conformational dynamics of chymotrypsin inhibitor 2 by coarse-grained simulations

A coarse-grained dynamic Monte Carlo (MC) simulation method is used to investigate the conformational dynamics of chymotrypsin inhibitor 2 (CI2). Each residue is represented therein by two interaction sites, one at the alpha-carbon and the other on the amino acid side-chain. The energy and geometry parameters extracted from databank structures are used. The calculated rms fluctuations of alpha-carbon atoms are in good agreement with crystallographic temperature factors. The two regions of the protein that pack against each other to form the main hydrophobic core exhibit negatively correlated fluctuations. The conformational dynamics could efficiently be probed by the time-delayed orientational and conformational correlation functions of the virtual bonds: the active site loop, excluding the active site bond, the turn region, and the N-terminal of the alpha-helix are relatively more mobile regions of the structure. A correlation is observed between the hydrogen/deuterium (H/D) exchange behavior and the long-time orientational and conformational autocorrelation function values for CI2. A cooperativity in the rotations of the bonds near in sequence is observed at all time windows, whereas the cooperative rotations of the bonds far along the sequence appear at long time windows; these correlations contribute to the stability of the secondary structures and the tertiary structure, respectively.

Haemodynamic effects of pneumoperitoneum during laparoscopic cholecystectomy: a prospective comparative study using bioimpedance cardiography

The haemodynamic effects of increased intra-abdominal pressure during laparoscopic cholecystectomy in 22 patients were compared with those in 11 patients undergoing open cholecystectomy; bioimpedance cardiography was used for monitoring at predetermined time intervals. In the laparoscopy group stroke volume, cardiac and ejection velocity indices were significantly decreased and the total peripheral resistance index was significantly increased during the insufflation period when compared with preinsufflation and corresponding values in the group undergoing open operation. Routine intraoperative parameters such as heart rate and blood pressure did not show any significant change or indicate alterations in cardiovascular performance during laparoscopic procedures. Continuous non-invasive cardiovascular monitoring by bioimpedance cardiography may be useful in patients with limited cardiac function.
