Objective: Contribute to the improvement of the anesthetic ECP of patients benefiting from MVA for incomplete abortion, Describe the methodology used for adoption of the dosage formula in Anesthesia for MVA, present the mathematical demonstration leading to the dosage formula in anesthesia for MVA. Materials and Methods: Our study was descriptive by mathematical demonstration of obtaining the equilibrium constant of the dosage formula of bipuvacaine 0.1% and Fentanyl 50 µg% adapted to the weight and specific size of patients treated anesthetically in MVA cases for incomplete abortion. We also carried out an operational research by first determining the interval where our equilibrium constant is included and secondly by means of the ends of the intervals found correlated to the ends of intervals of possible weights and sizes in the being normal human female of childbearing age to arrive at the real numerical value of the equilibrium constant of the BUKAVU Dosage Formula in the case of anesthesia for MVA during the management of incomplete abortions. Results: TWO-STAGE OPERATIONAL RESEARCH: • Determination of the interval where the equilibrium constant x = −0.95 x x by crossing the means between the extremes of volumes of anesthetic drugs giving a satisfactory sensory block without hemodynamic disturbance and the extremes of normal weight and height for women of childbearing age. We ended up with X = 0.37. Conclusion: At the end of our study which had the general objectives of contributing to the improvement of the anesthetic PEC of patients receiving MVA for incomplete abortion and specific objectives of describing the methodology used for adoption of the dosage formula in Anesthesia for MVA and present the mathematical demonstration which resulted in the dosage formula in nesthesia for MVA, it appears that the dosage formula of Bukavu, in case of intrathecal spinal analgesia of MVA for incomplete abortion provides precision on the specificity of the doses of bipuvacaine hypobarre 0.1% and Fentanyl 50 µg% reported to each patient according to her weight and height. Its application could therefore reduce morbidity and mortality and improve patient-practitioner comfort in the event of MVA for incomplete abortion following the dosage precision it provides.

Fine-needle aspiration technique under endoscopic ultrasound guidance:A technical approach for RNA profiling of pancreatic neoplasms

BACKGROUND Early diagnosis of pancreatic ductal adenocarcinoma(PDAC)has been a longstanding challenge.The prognosis of patients with PDAC depends on the stage at diagnosis.It is necessary to identify biomarkers for the detection and differentiation of pancreatic tumors and optimize PDAC sample preparation procedures for DNA and RNA analysis.Most molecular studies are done using paraffin-embedded blocks;however,the integrity of DNA and RNA is often compromised in this format.Moreover,RNA isolated from human pancreatic tissue samples is generally of low quality,in part,because of the high concentration of endogenous pancreatic RNAse activity present.AIM To assess the potential of endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA)to obtain specimens from pancreatic neoplasms for subsequent RNA molecular profiling,including next-generation sequencing(NGS).METHODS Thirty-four EUS-FNA samples were included in this study:PDAC(n=15),chronic pancreatitis(n=5),pancreatic cysts(n=14),mucinous cysts(mucinous cystic neoplasia/intraductal papillary mucinous neoplasia)n=7,serous cystic neoplasms n=5,and pseudocysts n=2.Cyst material consisted of cyst fluid and cyst wall samples obtained by through-the-needle biopsy(TTNB).Samples were stored at -80℃ until analysis.RNA purity(A260/230,A260/280 ratios),concentration,and integrity(RIN)were assessed.Real-time polymerase chain reaction was conducted on all samples,and small RNA libraries were prepared from solid mass samples.RESULTS RNA was successfully extracted from 29/34(85%)EUS-FNA samples:100% pancreatic adenocarcinoma samples,100% chronic pancreatitis samples,70% pancreatic fluid cyst samples,and 50%TTNB samples.The relative expression of GAPDH and HPRT were obtained for all successfully extracted RNA samples(n=29)including lowquality RNA specimens.Low concentration and nonoptimal RIN values(no less than 3)of RNA extracted from EUS-FNA samples did not prevent NGS library preparation.The suitability of cyst fluid samples for RNA profiling varied.The quality of RNA extracted from mucinous cyst fluid had a median RIN of 7.7(5.0-8.2),which was compatible with that from solid neoplasms[6.2(0-7.8)],whereas the quality of the RNA extracted from all fluids of serous cystic neoplasms and TTNB samples had a RIN of 0.CONCLUSION The results demonstrate the high potential of EUS-FNA material for RNA profiling of various pancreatic lesions,including low-quality RNA specimens.

Flexible bronchoscopy for foreign body aspiration in children:A single-centre experience

BACKGROUND The technological evolution of bronchoscopy has led to the widespread adoption of flexible techniques and their use for both diagnostic and therapeutic purposes.Currently,there is an active debate regarding the comparative efficacy and safety of rigid vs flexible bronchoscopy in the treatment of foreign body aspiration.AIM To evaluate our experience with tracheobronchial foreign body extraction using flexible bronchoscopy and provide a literature overview.METHODS This was a single-centre retrospective study.Twenty-four patients were enrolled between January 2017 and January 2023.Medical records of patients aged below 18 years who were admitted to authors’affiliated institution with a suspected diagnosis of foreign body aspiration were collected from hospital’s database to Microsoft Excel 2019.Data were analysed using MedCalc Statistical Software.RESULTS Patient ages varied from 9 months to 11 years.The median age was 23.5 months,95%confidence interval(CI)19.49-44.77.We observed age clustering in children with foreign body aspiration at our institution with three age subgroups:(1)0-25 months;(2)40-60 months;and(3)120-140 months.We expectancy of an organic tracheobronchial foreign body was significantly higher in 0-25 months subgroup than that in older ones when subgroups 40-60 and 120-140 months were combined together(odds ratio=10.0,95%CI:1.44-29.26,P=0.0197).Successful foreign body extraction was performed in all cases.Conversion to a rigid bronchoscope was not required in any of the cases.No major complications(massive bleeding,tracheobronchial tree perforation,or asphyxia)were observed.CONCLUSION Flexible bronchoscopy is an effective and safe method for tracheobronchial foreign body extraction in children.

Extraction of Aspirated Headscarf Pins with Fiberoptic Bronchoscopy

Background: Foreign body aspiration is a common yet preventable health problem. Headscarf pin aspiration is a unique example of aspirated foreign bodies in young Muslim women usually removed using the rigid bronchoscope. However, the flexible bronchoscope is increasingly used for this purpose. This prospective study was conducted in Sulaimaniyah Teaching Hospital, Sulaimaniyah, Iraq and aimed to evaluate the usefulness of fiberoptic bronchoscope for removal of aspirated headscarf pins in view of the relevant literature. Methodology: Fifty female patients with headscarf pin aspiration were managed by fiberoptic bronchoscopy over an 8-year period (January 2008 to December 2015). The procedure was performed under local anesthesia and conscious sedation through the mouth. Results: The age ranged from 10 to 45 years with a mean of 27.5. All patients had cough, five had unilateral wheeze (10%) while haemoptysis occurred twice (4%). Fiberoptic bronchoscopy succeeded in 45 cases (90%). Rigid bronchoscopy under general anesthesia was necessary in (n = 4, 8%) while one patient (2%) required thoracotomy. ?Conclusion: Fiberoptic bronchoscopy is safe and effective in removal of aspirated headscarf pins and should be tried first.

The use of fiberoptic bronchoscope to remove aspirated tracheobronchial foreign bodies: Our experience

Background: Foreign body (FB) aspiration is a common emergency in our practice. The routine method of removal is via rigid bronchoscopy (RB) under general anesthesia. This is the preferred procedure particularly in children who form the major affected population. Fiberoptic bronchoscopy (FOB) has also been used for FB removal in many countries, though in Iraq, the standard mean remains rigid bronchoscopy. Objective: Herein, we present 5 cases of FB inhalation in adults in whom FOB was used for removal. The aim is to test its feasibility with literature review. Setting: the department of thoracic surgery/Sulaimania Teaching Hospital/Sulaimania/Iraq. Study Design: a prospective study of 5 patients. Patients and methods: 5 patients (3 females and 2 males) with different bronchial or laryngeal FBs in whom FOB was used as a method for removal are presented. The age ranged from 16 to 71 years. The clinical and radiographic features are recorded. In all these patients, initial FOB examination under local anesthesia transorally or via tracheotomy stoma was done. When removed by this method failed, RB under GA was used and when this failed, thoracotomy was the last resort. Results and Conclusions: FBs encountered in this paper consisted of pins (n = 2), sewing needle (n = 1), speech valve (n = 1) and a medical leach (n = 1). Three FBs (medical leach, speech valve and one pin) were successfully removed by FOB. A pin in RMB was visualized but failed to be removed by FOB and therefore, RB was required for its retrieval, while a needle in left lower lobe was invisible by both FOB and RB and thus surgery was necessary to remove it. We conclude that in adolescent or adult patients with bronchial FBs, FOB should be tried first for removal. If this fails then RB can be used. To increase its success, FOB should be combined with certain accessories like special FB forceps and fluoroscopy.

Successful treatment of a rare subcutaneous emphysema after a blow-out fracture surgery using needle aspiration:A case report

BACKGROUND Many cases of emphysema associated with blow-out fractures occur before surgery due to trauma.However,emphysema can occur even after surgery,and most of such cases are managed conservatively and allowed to resolve.Swelling in the periorbital area due to emphysema that occurs after surgery can make early recovery difficult.CASE SUMMARY Herein,we describe a case of postoperative subcutaneous emphysema that was treated using a simple needle aspiration method.A 48-year-old male patient visited the hospital with a blow-out fracture of the left medial orbital wall and nasal bone fracture.One day postoperatively,swelling and crepitus in the left periorbital area were observed,and follow-up computed tomography showed emphysema in the left periorbital subcutaneous area.Needle aspiration using an 18-gauge needle and syringe was used to relieve the emphysema.The symptoms of sudden swelling improved immediately,and no recurrence was observed.CONCLUSION We conclude that needle aspiration is a useful method that could help in relieving symptom,resolving discomfort,and enabling early return to daily life in patients with postoperative subcutaneous emphysema.

Aspirations of Fisherfolk Communities on Their Children’s Education in Albay, Asid, and Ragay Gulfs of Bicol, Philippines

The study explores the yearnings of fisherfolks on their child’s education, hindrances, and factors that shape their desire as parents. Field observations and key informant interview among elder members of fisherfolk communities surrounding the Albay, Ragay, and Asid Gulfs of the Bicol Region was utilized. The study revealed that the majority of the fisherfolk parents do not want their children to continue fishing as their main source of livelihood because of potential risks, hardships, and cultural factors like collectivism, close family ties, and dependence on the elders. The parents’ aspirations were shaped by their persistence over various threats, fears, personal unfulfilled dreams, and career opportunities thru education. Most of the parents desired a college education and a safe and secure profession for their children. The study deduced that these challenges can be a contributory factor for the declining number of fisherfolks surrounding the gulfs. Influencing this sector is the factor motivating fishers in their aspirations for their children’s education. The study recommends introducing strategies for fisherfolks to develop a strong sense of hope and drive in realizing their aspirations and further research on the impact of culture, the role of women and children, and fisherfolks and their success stories.

Treatment of postherpetic neuralgia by bone marrow aspirate injection:A case report

BACKGROUND Postherpetic neuralgia(PHN)is the most frequent and a difficult-to-treat complication of herpes zoster(HZ).Its symptoms include allodynia,hyperalgesia,burning,and an electric shock-like sensation stemming from the hyperexcitability of damaged neurons and varicella-zoster virus-mediated inflammatory tissue damage.HZ-related PHN has an incidence of 5%–30%,and in some patients,the pain is intolerable and can lead to insomnia or depression.In many cases,the pain is resistant to pain-relieving drugs,necessitating radical therapy.CASE SUMMARY We present the case of a patient with PHN whose pain was not cured by conventional treatments,such as analgesics,block injections,or Chinese medicines,but by bone marrow aspirate concentrate(BMAC)injection containing bone marrow mesenchymal stem cells.BMAC has already been used for joint pains.However,this is the first report on its use for PHN treatment.CONCLUSION This report reveals that bone marrow extract can be a radical therapy for PHN.

New treatment for gastric duplication cyst:Endoscopic ultrasonography-guided fine-needle aspiration combined with lauromacrogol sclerotherapy:A case report

BACKGROUND Gastric duplication cysts are very rare disease that are mainly diagnosed by endoscopic ultrasonographic fine-needle aspiration biopsy.In the past,this disease was usually treated with traditional surgery and rarely with minimally invasive endoscopic surgery.However,minimally invasive endoscopic therapy has many advantages,such as no skin wound,organ preservation,postoperative pain reduction,early food intake,fewer postoperative complications,and shorter post-procedure hospitalization.CASE SUMMARY We report a case of endoscopic ultrasonography-guided fine-needle aspiration(EUS-FNA)combined with lauromacrogol sclerotherapy for pyloric obstruction due to gastric duplication cysts.CONCLUSION EUS-FNA combined with lauromacrogol sclerotherapy provides a new option for the treatment of gastrointestinal duplication cysts.

Endoscopic ultrasound-guided fine-needle aspiration pancreatic adenocarcinoma samples yield adequate DNA for next-generation sequencing:A cohort analysis

BACKGROUND Genetic tests are increasingly performed for the management of unresectable pancreatic cancer.For genotyping aimed samples current guidelines recommend using core specimens,although based on moderate quality evidence.However,in clinical practice among the endoscopic ultrasound(EUS) guided tissue acquisition methods,fine needle aspiration(FNA) is the most widely performed.AIM To assess the adequacy for next generation sequencing(NGS) of the DNA yielded from EUS-FNA pancreatic adenocarcinoma(PDAC) samples.METHODS Between November 2018 and December 2021,105 patients with PDAC confirmed by EUS-FNA were included in the study at our tertiary gastroenterology center.Either 22 gauge(G) or 19G FNA needles were used.One pass was dedicated to DNA extraction.DNA concentration and purity(A260/280,A260/230) were assessed by spectrophotometry.We assessed the differences in DNA parameters according to needle size and tumor characteristics(size,location) and the adequacy of the extracted DNA for NGS(defined as A260/280 ≥ 1.7,and DNA yield:≥ 10 ng for amplicon based NGS,≥ 50 ng for whole exome sequencing [WES],≥ 100 ng for whole genome sequencing [WGS]) by analysis of variance and ttest respectively.Moreover,we compared DNA purity parameters across the different DNA yield categories.RESULTS Our cohort included 49% male patients,aged 67.02 ± 8.38 years.The 22G needle was used in 71%of the cases.The DNA parameters across our samples varied as follows:DNA yield:1289 ng(inter quartile range:534.75-3101),A260/280 = 1.85(1.79-1.86),A260/230 = 2.2(1.72-2.36).DNA yield was > 10 ng in all samples and > 100 ng in 93% of them(one sample < 50 ng).There were no significant differences in the concentration and A260/280 between samples by needle size.Needle size was the only independent predictor of A260/230 which was higher in the 22G samples(P =0.038).NGS adequacy rate was 90% for 19G samples regardless of NGS type,and for 22G samples it reached 89% for WGS adequacy and 91% for WES and amplicon based NGS.Samples with DNA yield > 100 ng had significantly higher A260/280(1.89 ± 0.32 vs 1.34 ± 0.42,P = 0.013).Tumor characteristics were not corelated with the DNA parameters.CONCLUSION EUS-FNA PDAC samples yield DNA adequate for subsequent NGS.DNA amount was similar between 22G and 19G FNA needles.DNA purity parameters may vary indirectly with needle size.

Lipoid Pneumonia Caused by Diesel Aspiration: A Case Report and Literature Review

Diesel poisoning is a rare clinical condition.On September 27,2021,a 55-year-old male who mistakenly inhaled 20 mL of diesel through a siphon was admitted to our hospital.The main symptoms were cough and asthma.Chest computed tomography(CT)showed both lungs scattered with patchy consolidation,ground-glass shadow,exudation,and pleural effusion.After 61 days of lung rehabilitation training and other supportive treatment,including oxygen therapy,postural drainage,ventilator support,bronchoalveolar lavage,hemoperfusion,continuous renal replacement therapy(CRRT),hormones,and antibiotics,the patient’s condition improved,and the patient was discharged.Through literature review,we found that lung consolidation,ground-glass shadow,nodular lesions,and pleural effusion can be observed on chest images of patients with lipoid pneumonia,with severe cases showing diffuse lesions involving both lungs,possibly secondary to respiratory failure.Children with acute critical illness deteriorates rapidly and have poor prognosis,whereas adults or patients with chronic poisoning have better prognosis after active treatment.

“亲近”还是“疏远”?———联合投资伙伴的社会期望绩效反馈与联合风险投资关系

风险投资是支持创新创业的重要活动,但风险投资的不确定性催生了“抱团”行为的出现,与风险投资联合投资伙伴选择相关的研究也开始逐渐丰富。本文借鉴企业行为理论中的绩效反馈,以2000—2020年CVSource中记录的投资交易数据,分析了风险投资机构联合投资伙伴的社会期望绩效反馈对双方联合关系强度的影响。研究发现,当联合投资伙伴处于社会期望绩效落差状态时,为得到互惠交易流,风险投资机构与期望绩效水平较高的联合投资伙伴之间的关系变得亲近。当联合投资伙伴处于社会期望绩效顺差状态时,高期望绩效水平的联合投资伙伴为避免摊薄收益,选择不进行联合投资,因而与风险投资机构之间的关系变得疏远。此外,风险投资机构与联合投资伙伴之间的绩效差距也是进一步导致双方联合关系强度降低的重要因素。本研究从绩效反馈理论视角拓展了风险投资联合行为的相关研究,打开了联合投资伙伴之间关系动态性的黑箱,揭示了风险投资联合行为的内在规律。

《交泰韵》古全浊声母清化方式研究

明代韵书《交泰韵》中古浊音声母已经清化。通过统计分析《交泰韵》阳类塞音塞擦音小韵的读音,同时结合韵书凡例的内容和反切,我们认为:中古浊塞音浊塞擦音仄声字在17世纪前后汴洛一带方言中读不送气音。吕坤为满足韵书设计的需要而制定的各种调和语音的方法,一方面说明了吕坤尊重语言事实的朴素思想,另一方面也说明旧的音韵理论已不能充分解释语言的发展变化。《交泰韵》古全浊声母清化的方式是“平声送气仄声不送气”。

FNAC联合FNA-Tg检测在甲状腺乳头状癌颈侧区淋巴结转移中的诊断价值

目的探讨超声引导下细针穿刺细胞学检查(FNAC)联合细针穿刺洗脱液甲状腺球蛋白(FNA-Tg)在甲状腺乳头状癌(PTC)颈侧区淋巴结转移中的诊断价值。方法回顾性分析行颈侧区淋巴结清扫术的200例PTC患者的临床资料,术前超声评估颈侧区有可疑转移淋巴结236枚,术后病理证实转移性淋巴结178枚,非转移性淋巴结58枚,所有患者均行FNAC、FNA-Tg检查。以术后病理结果为金标准,比较FNAC、FNA-Tg、FNAC联合FNA-Tg的诊断结果及诊断效能。结果FNAC联合FNA-Tg诊断PTC颈侧区淋巴结转移的灵敏度、准确度、阴性预测值高于单一诊断方法,差异具有统计学意义(P<0.05)。结论FNAC与FNA-Tg检测方法在临床中能够用于诊断PTC颈侧区淋巴结转移,两者联合检测可以进一步提高诊断效能,值得推广及应用。

过去20年城乡高中生的教育效用与教育志向:基于三个出生队列的历史比较研究

本研究采用时间滞后设计,考察过去20年我国高中生教育效用和教育志向水平的年代和城乡差异,以及二者与个体学业成绩、父母学历之间关系的年代和城乡差异。分别在1999年、2010年、2018年对来自相同的三个地区(包括城市和农村)、相同学校的高中生进行问卷调查,使用协方差分析和回归分析进行数据分析。结果发现:(1)自1999年至2018年,城乡高中生的教育效用都遵循先下降、后回升的变化趋势;在教育志向上,城市高中生无明显变化,而农村高中生教育志向上升并超越城市高中生;(2)高中生教育效用、教育志向受父母学历和学业成绩等微观因素影响,且受年代和城乡宏观社会历史因素调节。相比于其他年份,2010年时成绩较差学生的教育效用更低、2018年时成绩较差学生的教育志向更高;自1999年至2018年,低父母学历对农村高中生教育志向的影响方式由“枷锁效应”转变为“鞭策效应”。我国过去20年的社会变迁使城乡高中生对教育的价值认同发生系统性变化,且宏观社会历史因素的演变改变了教育的价值认同形成的微观机制。

利用持续质量改进工具降低重症脑血管病患者误吸发生率的实践

目的探讨持续质量改进工具在减少重症脑血管病患者误吸发生中的作用。方法选择2020年11月—2021年6月在本院神经内科ICU实施肠内营养的重症脑血管病患者104例作为研究对象,按照入住时间分为对照组和观察组两组,其中2020年11—12月收治的患者53例作为对照组,2021年4—6月收治的51例患者作为观察组。对照组给予常规护理干预,观察组在常规护理的基础上进行持续质量改进活动干预,比较干预前后两组患者误吸、吸入性肺炎发生率的差异。结果持续质量改进活动干预后重症脑血管病患者误吸的发生率由20.75%降低到5.88%(P<0.05),目标达标率109.26%,进步率71.66%。结论利用持续质量改进工具能有效减少重症脑血管病患者误吸的发生。
