Objective: To scrutinize patterns of multi-drug-resistant uropathogenic Escherichia coli (UPEC) strains and particularly of fluoroquinolone-resistance this is an alternative choice for the treatment of urinary tract infections.
Methods: Bacterial samples (n = 250) were collected from out-patients from August 2012 to August 2014 Islamabad. Antibiotic susceptibility profiling and determination of mini-mum inhibitory concentrations (MICs) and minimum bactericidal concentrations were performed according to the guidelines of Clinical and Laboratory Standards Institute (CLSI, 2012). Genes, qnrA, qnrB and qnrS were identified by DNA amplification and sequencing.
Results: The highest percentage of UPEC isolates were resistant to co-trimoxazole (82%) followed by cephalothin (80%), 2nd Gen, 3rd Gen and 4th Gen cephalosporins, respectively. Resistance against gentamicin, amikacin remained 29% and 4%. For other drugs including nitrofurantoin, tetracycline, carbapenem and beta-lactam inhibitors remained below 10%. Altogether, 59% of the isolates were resistant to at least three antibiotics including one fluoroquinolone. Overall, MICs for ciprofloxacin remained (MIC≥256 mg/mL) and for levofloxacin (MIC≥16 mg/mL and 32 mg/mL). No significant differences were observed regarding MIC values of extended spectrum b-lactamase (ESBL) and non-ESBL producers. For qnrS and qnrB positive isolates MICs remained above 32 mg/mL. Prevalence of UPEC was significantly higher among females and 40% of the isolates were ESBL producers.
Conclusions: Higher percentages of ESBL producing UPEC were associated with uri-nary tract infections. Moreover, the majority of these isolates were multi-drug resistant and fluoroquinolone-resistant.

Rotator cuff tears commonly cause shoulder pain and functional impairment, prompting surgical intervention such as miniopen and arthroscopic methods, each with distinct benefits. This study aimed to compare the clinical outcomes and complications of these two approaches. Methods: A retrospective analysis was conducted on 165 patients who underwent rotator cuff repair using either arthroscopic-assisted mini-open or full arthroscopic approaches. Patient demographics, tear characteristics, clinical outcomes, and complications were assessed, with statistical analyses conducted to discern differences between the groups. Results: Among the patients, 74 (53.2%) received the mini-open approach, while 65 (46.8%) underwent arthroscopic repair, with a mean follow-up of 19.91 months. The mini-open group exhibited significantly higher postoperative American Shoulder and Elbow Surgeons (ASES) scores compared to the arthroscopic group (P=0.002). Additionally, the mini-open group demonstrated a more significant improvement in ASES scores from preoperative to postoperative assessments (P=0.001). However, the arthroscopic method had a significantly longer operative time (P<0.001). Complications, including anchor placement issues, frozen shoulder, infection, and re-rupture, occurred in 17.3% of patients overall. Re-rupture rates were 13.5% for mini-open and 6.2% for full arthroscopic repair, with no significant difference between the two methods (P=0.317). Conclusions: Both the mini-open and arthroscopic methods yielded favorable clinical outcomes for rotator cuff tear treatment, but the mini-open group exhibited superior results. Surgeons should consider patient characteristics, tear attributes, and surgical expertise when selecting the appropriate technique. Level of evidence: III.

PURPOSE: The aims of this study were to assess the prevalence of nocturia and nocturnal polyuria (NP) and to define new cutoff values according to age and sex for both conditions. METHODS: Data from a population-based prevalence survey conducted among a random sample of 2,128 adults were analyzed in this study. Participants were requested to fill out a questionnaire including the International Continence Society (ICS) definitions of lower urinary tract symptoms and the International Consultation on Incontinence Questionnaire - Short Form. Additionally, a 1-day bladder diary was given to each individual. The participants were divided into 5 age groups. The prevalence of nocturia was calculated based on definitions of nocturia as ≥1 voiding episodes, ≥2 episodes, and ≥3 episodes. NP was evaluated according to the ICS definition. The mean±standard errors and 95th percentile values were calculated in each group as new cutoff values for NP. RESULTS: The prevalence of nocturia was estimated as 28.4%, 17.6%, and 8.9% for ≥1, ≥2, and ≥3 voiding episodes each night, respectively. When nocturia was defined as 2 or more voiding episodes at night, the prevalence decreased significantly. The mean NP index was 29.4%±15.0% in men and 23.1%±11.8% in women. For the age groups of <50 years, 50–59 years, and ≥60 years, the new cutoff values for the diagnosis of NP were calculated as 48%, 69%, and 59% for men and 41%, 50%, and 42% for women, respectively. CONCLUSIONS: We found that the definition of nocturia was still controversial and that waking up once for voiding might be within the normal spectrum of behavior. The definition of NP should be modified, and new cutoff values should be defined using the data presented in our study and in other forthcoming studies.

: The subaxial cervical pedicle screwing technique shows powerful biomechanical properties for posterior cervical fusion. When applying a pedicle screw using the freehand technique, it is essential to analyse cervical computed tomography and plan the surgery accordingly. Normal cervical computed tomography is usually performed in the supine position, whereas during surgery, the patient lies in a prone position. This fact leads us to suppose that radiological evaluations may yield misleading results. Our study aimed to investigate whether there is any superiority between preoperative preparation on computed tomography performed in the prone position and that performed in the supine position. Methods : This study included 17 patients (132 pedicle screws) who were recently operated on with cervical vertebral computed tomography in the prone position and 17 patients (136 pedicle screws) who were operated on by conventional cervical vertebral computed tomography as the control group. The patients in both groups were compared in terms of age, gender, pathological diagnosis, screw malposition and complications. A screw malposition evaluation was made according to the Gertzbein-Robbins scale. Results : No statistically significant difference was observed between the two groups regarding age, gender and pathological diagnosis. The screw malposition rate (from 11.1% to 6.9%, p<0.05), mean malposition distance (from 2.18 mm to 1.86 mm, p <0.05), and complications statistically significantly decreased in the prone position computed tomography group. Conclusion : Preoperative surgical planning by performing cervical vertebral computed tomography in the prone position reduces screw malposition and complications. Our surgical success increased with a simple modification that can be applied by all clinicians without creating additional radiation exposure or additional costs.

PURPOSE: In this study, we aimed to evaluate the amount of marginal gap with two different substructure materials using identical margin preparations. MATERIALS AND METHODS: Twenty stainless steel models with a chamfer were prepared with a CNC device. Marginal gap measurements of the galvano copings on these stainless steel models and Co-Cr copings obtained by a laser-sintering method were made with a stereomicroscope device before and after the cementation process and surface properties were evaluated by scanning electron microscopy (SEM). A dependent t-test was used to compare the mean of the two groups for normally distributed data, and two-way variance analysis was used for more than two data sets. Pearson's correlation analysis was also performed to assess relationships between variables. RESULTS: According to the results obtained, the marginal gap in the galvano copings before cementation was measured as, on average, 24.47 +/- 5.82 microm before and 35.11 +/- 6.52 microm after cementation; in the laser-sintered Co-Cr structure, it was, on average, 60.45 +/- 8.87 microm before and 69.33 +/- 9.03 microm after cementation. A highly significant difference (P<.001) was found in marginal gap measurements of galvano copings and a significant difference (P<.05) was found in marginal gap measurements of the laser-sintered Co-Cr copings. According to the SEM examination, surface properties of laser sintered Co-Cr copings showed rougher structure than galvano copings. The galvano copings showed a very smooth surface. CONCLUSION: Marginal gaps values of both groups before and after cementation were within the clinically acceptable level. The smallest marginal gaps occurred with the use of galvano copings.

BACKGROUND: Behcet's disease (BD) is a chronic, recurrent inflammatory systemic vasculitis. Evidence for increased atherosclerosis in BD has been observed. The relation between cardiovascular risk factors and increased atherosclerosis in patients with BD is still controversial. OBJECTIVE: We performed this study to evaluate arterial stiffness in patients with BD by using noninvasive radiological methods such as carotid artery intima-media thickness (CIMT), ankle-brachial pressure index (ABPI), coronary artery calcium score (CACaS), and their relation to serum fetuin-A levels, which was recently found to be important in vascular calcification. METHODS: This prospective study included 26 patients with BD and 25 control subjects. In all patients, the CIMT, ABPI, CACaS, and serum fetuin-A levels were examined. RESULTS: The CIMT and CACaS were statistically higher and the ABPI was statistically lower in BD patients than in the control group. All p-values were <0.001. Positive correlations were found between the CACaS and CIMT, and negative correlations were found between the CACaS and ABPI. Although the values of fetuin-A were higher in BD, the difference was not statistically significant (p=0.064). However, the correlations found between fetuin-A levels and CIMT and between fetuin-A levels and CACaS were significant. CONCLUSION: The CIMT, CACaS, and ABPI are all useful in detecting structural and functional vascular damage in BD.

Low-grade malignant eccrine spiradenoma (spiradenocarcinoma) is a rare sweat gland tumor, which usually arises from a pre- existing benign eccrine spiradenoma. This paper presents the case of a 55-year-old male who had a lesion in his right elbow for 10 years. The microscopic examination revealed a well-demarcated, multilobulated tumor in the dermis and subcutis, which presented with many blood-filled vessels and extensive hemorrhage.The tumor was composed of hyperchromatic, round to oval cells with nucleolar prominence, mild to moderate atypia, and increased mitotic index. Additionally, lymphangiectatic appearance was observed in areas with prominent stromal lymphedema. P53 and Ki-67 had high positivity. Surgical excision of the lesion was performed with adequate surgical margins, and the dissected lymph nodes in the axilla were tumor-negative. After 15 months of follow-up, there was no recurrence or distant metastasis.

Excessive production of reactive oxygen species (ROS) and endoplasmic reticulum (ER) stress-mediated responses are critical to embryonic development in the challenging in vitro environment. ROS production increases during early embryonic development with the increase in protein requirements for cell survival and growth. The ER is a multifunctional cellular organelle responsible for protein folding, modification, and cellular homeostasis. ER stress is activated by a variety of factors including ROS. Such stress leads to activation of the adaptive unfolded protein response (UPR), which restores homeostasis. However, chronic stress can exceed the toleration level of the ER, resulting in cellular apoptosis. In this review, we briefly describe the generation and impact of ROS in preimplantation embryo development, the ROS-mediated activation mechanism of the UPR via the ER, and the subsequent activation of signaling pathways following ER stress in preimplantation embryos.

Objective:
The primary purpose of this study was to determine mortality rates and durations, survival status, and predictive prognosis parameters based on vital signs, hematology, and blood gas analyses in neonatal diarrheic calves.
Methods:
The hospital automation system retrospectively obtained data from 89 neonatal diarrheic calves.
Results:
It was found that 42.7% (38/89) of the calves brought with the complaint of diarrhea died during hospitalization or after discharge. Short-term and long-term fatalities were a median of 9.25 hours and a median of 51.50 hours, respectively. When the data obtained from this study is evaluated, body temperature (°C), pH, base excess (mmol/L), and sodium bicarbonate (mmol/L) parameters were found to be lower, and hemoglobin (g/ dL), hematocrit (%), lactate (mmol/L), chloride (mmol/L), sodium (mmol/L) and anion gap (mmol/L) parameters were found to be higher in dead calves compared to survivors.Accordingly, hypothermia, metabolic acidosis, and dehydration findings were seen as clinical conditions that should be considered. Logistic regression analysis showed that lactate (odds ratio, 1.429) and CI − (odds ratio, 1.232) concentration were significant risk factors associated with death in calves with diarrhea.
Conclusions
and Relevance: According to the findings obtained from this study, the determination of lactate and Cl − levels can be used as an adjunctive supplementary test in distinguishing calves with diarrhea with a good prognosis.

OBJECTIVETo evaluate physico-chemical properties and antimicrobial potential of indigenous honey samples against different reference strains including Escherichia coli ATCC 8739, Enterobacter aerogenes ATCC 13048, Pseudomonas aeroginosa ATCC 9027, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Salmonella typhi ATCC 14028, Klebsiella pneumonia ATCC 13883, Aspergillus niger ATCC 16404, Rhizopus oligosporus PCSIR1, Candida albicans ATCC 14053 and Candida utilis ATCC 9950.
METHODSBy using standard methods samples were evaluated for their antimicrobial properties including additive effect of starch and non-peroxidase activity, antioxidative properties (phenol contents, flavonoid contents, 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity). Prior to this evaluation, complete physico-chemical properties including pH, color, ash contents, protein contents, moisture contents, hydroxymethyl furfural contents, total sugar contents, reducing sugar and non-reducing sugar contents were analyzed.
RESULTSRelatively higher ash contents were found in the Siddar honey i.e. (0.590 0±0.033 6)% and small honey showed relatively higher protein contents i.e. (777.598±9.880) mg/kg. The moisture contents of tested honey samples ranged between 13.8%-16.6%, total sugar contents from 61.672%-72.420% and non-reducing sugar contents from 1.95%-3.93%. Presences of phenolic contents indicate higher antioxidant potential of these honey samples. All bacteria showed clear inhibition zones in response to tested honey samples whereas fungi and yeast showed inhibition at higher concentrations of these honey samples. For Escherichia coli, Bacillus subtilis, Salmonella typhi, Pseudomonas aeroginosa and Aspergillus niger, overall the small honey showed the higher activity than other honey samples.
CONCLUSIONPhysico-chemical analysis of honey samples confirmed good quality of honey according to the standards set by European Union Commission and Codex Alimentarius Commission. Evaluation of these honey samples confirms antimicrobial potential of particular types of honeys indigenous to Pakistan.
