Hypothetical study of small hive beetle aethina tumida infestation in honeybees, risk commodities and probabilities for its introduction in tĆ¼rkiye
TĆ¼rkiye is the second-largest honey producer globally; however, the export of honey and bee products does not adequately
support the beekeeping industry. Pests account for the largest share of expenditure for agents found in honeybees in the country. Although
the Small Hive Beetle (SHB) has not been detected in TĆ¼rkiye, a risk assessment was performed to determine what happens if it enters the
country. The risk assessment included: a) hazard identification; b) risk pathway determination; c) risk assessment for entry via the identified
pathways; and d) outcome assessment for becoming endemic in TĆ¼rkiye. The Risk AMP add-in program was used to assess the probability
of distribution for each method of entry, pathway, and simulation. According to the simulations, the probability of SHB introduction in
TĆ¼rkiye varies from 0.17 per 1000 events/days (1.7 per 10000 days or 27 years) to 0.6 per 1000 events/imports (6 per 10000 days or 27
years). The highest likelihood of introduction comes from fruit import (11/15) and soil/compost import (4/15). The mean probability of
introducing SHB infestation after 1000 iterations of the constructed model is 0.37 per 1000 events/days (3.7 within 10000 days or 27 years).
Finally, the simulated average cost of SHB after the possible introduction is 523 million US $ for TĆ¼rkiye. With these simulated data, risk
assessment of a non-detected pest, SHB, was determined for TĆ¼rkiye
Microscopic and molecular detection of Nosema spp. in honeybees of Turkey
International audienceAbstractIn this study, we aimed to determine the prevalence of Nosema spp. in honeybees of Turkey. For this aim, adult honeybee (Apis mellifera) samples were collected from 1621 colonies within 95 apiaries located in 22 provinces of Turkey. Samples were examined microscopically. In case of positivity, spore identification was done by multiplex PCR. At the end of microscopic examination, Nosema spp. spores were detected in 7 out of 22 provinces (31.8Ā %), and 16 out of 95 colonies (16.8Ā %) that represent 1621 colonies. According to PCR results, 1 out of 16 isolates (6.25Ā %) was Nosema apis, and 15 out of 16 isolates (93.75Ā %) were Nosema ceranae. The result of our study indicated that N.ceranae is the dominant species in Turkey

Some of the genotoxic/carcinogenic substances or metabolites in cigarette smoke are capable of passing through the placenta and harming a newbornās health. Smoking is also known as a factor in the formation of oxidative damage and the main mechanism involved in the carcinogenic process. Predetermining this genotoxic risk can be successfully achieved by measuring certain parameters of oxidative stress. The comet assay is considered an important biomarker for the evaluation of genotoxic substances and is effective for detecting DNA damage caused by smoking. This study examined third trimester bloods and the cord blood of 28 actively smoking and 22 non-smoking mothers in terms of DNA damage and oxidative stress parameters. Cu/Zn superoxide dismutase (CuZn-SOD), malondialdehyde (MDA), catalase (CAT), plasma nitrite/nitrates (NO2ā¢/NO3ā¢), selenium-dependent glutathione peroxidase (Se-GPx), Cu, and Zn levels were measured as indicators of oxidative damage. There were no significant increases in DNA damage of the actively smoking pregnant group in comparison with the non-smoking pregnant group, either in the third trimester or cord blood. Oxidative stress parameters of smoker and non-smoker groups were statistically different for MDA (p<0.05), CuZn-SOD (p<0.01), Se-GPx (p<0.05) values while the difference was not significant for NO2ā¢/NO3ā¢, CAT, Zn, and Cu values. The same values were also investigated in cord blood, and only NO2ā¢/NO3ā¢ (p<0.01), Se-GPx (p<0.01 and CAT (p<0.001) values were found statistically different. Smoking mothers may have been exposed to more oxidative stress than non-smoking mothers.Pojedine genotoksiÄne/kancerogene supstancije ili metaboliti u cigaretnom dimu mogu proÄi kroz posteljicu i naÅ”tetiti zdravlju novoroÄenÄeta. PuÅ”enje je takoÄer poznato kao Äimbenik pri nastanku oksidacijskog oÅ”teÄenja DNA i u procesu kancerogeneze. Ovaj genotoksiÄni rizik može se uspjeÅ”no odrediti mjerenjem odreÄenih parametara oksidacijskog stresa. Komet-test smatra se važnim bioloÅ”kim biljegom pri evaluaciji genotoksiÄnih supstancija i iznimno uÄinkovitim sredstvom pronalaženja oÅ”teÄenja DNA uzrokovanih puÅ”enjem. Ova studija prouÄava krv trudnica u treÄem tromjeseÄju trudnoÄe i fetalnu krv 28 majki aktivnih puÅ”aÄica te 22-ju majki nepuÅ”aÄica vezano za oksidacijska oÅ”teÄenja DNA i parametre oksidacijskog stresa. Razine Cu/Zn superoksidne dismutaze (CuZn-SOD), malondialdehida (MDA), katalaze (CAT), nitrita/nitrata u plazmi (NO2-/NO3-), selenijeve glutation peroksidaze (Se-GPx), Cu i Zn mjerene su kao pokazatelji oksidacijskog oÅ”teÄenja. Nije bilo znaÄajnih poveÄanja oÅ”teÄenja DNA u skupini trudnica aktivnih puÅ”aÄica u usporedbi sa skupinom trudnica nepuÅ”aÄica, ni u krvi iz treÄeg tromjeseÄja ni u fetalnoj krvi. Parametri oksidacijskog stresa puÅ”aÄke i nepuÅ”aÄke skupine bili su statistiÄki razliÄiti za vrijednosti MDA (p<0,05), CuZn-SOD (p<0,01), Se-GPx (P<0,05), dok razlika nije bila znaÄajna za vrijednosti NO2-/NO3-, CAT, Zn i Cu. Iste su vrijednosti ispitane i u fetalnoj krvi, a jedino su vrijednosti NO2-/NO3- (p<0,01), Se-GPx (p<0,01) i CAT (p<0,001) bile statistiÄki razliÄite. Vjerojatno je da su majke puÅ”aÄice bile izložene veÄem oksidacijskom stresu od majki nepuÅ”aÄica

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
Broncholithiasis with Recurrent Lithoptysis: A Case Report
Objective: To report a case of broncholithiasis with different types of calculi in the tracheobronchial tree. Clinical Presentation and Intervention: A 50-year-old male who suffered from hemoptysis presented with recurrent broncholith expectoration due to past tuberculous middle lobe syndrome. Bronchoscopic examination revealed loose and embedded broncholiths located at two different bronchi. A surgical resection was suggested, but he refused. Conclusion: The diagnosis of broncholithiasis should be kept in mind in patients who had hemoptysis and calcified mediastinal lymph nodes on thorax computerized tomography, and diagnostic bronchoscopy should be done to prove the relationship of the tracheobronchial tree with a broncholith.

Oxidative effects of aluminum on testes and erythrocytes in rats
Aluminum (Al) has been proposed as an environmental factor contributing to free radical-mediated cytotoxicity and reproductive toxicity. The main goal of this study is to evaluate the effect of Al on oxidative stress status in rat testes and erythrocyte. 40 male Wistar rats were divided into two equal groups as experimental and control groups. Aluminum chloride solution (AlCl3) was orally administered (75 mg/kg/day) to the experimental group daily using a special canule for 30 days. After administration, the rats were sacrificed and the testes were taken out and blood was depleted. Al concentrations in tissue samples and erythrocytes were analyzed. The activities of antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) as well as the concentration of malondialdehyde (MDA) were measured in the samples. The results indicated that Al remarkably accumulated in testes and erythrocytes. In the experimental group, antioxidant enzyme activities, such as SOD and GPx, significantly decreased in testes and erythrocytes samples while MDA levels were higher than control group (p < 0.001). In the current study, it is concluded that subchronic exposure to Al has destructive effect on testes and erythrocytes due to oxidative stress in rats
