Authors: Huang Jin-Xi , Chen Qiang , Hong Song-Ming , Hong Jun-Jie , Cao Hua
Published: August 2022

We performed a single-centre retrospective analysis using data from databases that were prospectively maintained in our centre between January 2019 and September 2021. Patients were divided into two groups based on the degree of pulmonary fissure completeness (PFC), using the fissure development scoring system. Patients with grades 2 or 3 PFC were considered to have incomplete pulmonary fissures and were included in Group A, and patients with grades 0 and 1 were considered to have complete pulmonary fissures and were included in Group B. The differences in demographics, perioperative characteristics and clinic outcomes between the two groups were evaluated. Multivariate logistic regression analysis was performed. A total of 213 patients with congenital lung malformation (CLM) underwent video-assisted thoracoscopic lobectomy. There were 30 patients in Group A and 183 patients in Group B. Our data showed that compared with Group B, Group A had a higher incidence of complications, especially Clavien-Dindo grade II and grade III complications. The degree of PFC was significantly correlated with the length of chest tube drainage and postoperative hospital stay. Multivariate logistic regression analysis showed that the degree of PFC could be used to predict the incidence of postoperative complications.

Conclusions

The degree of PFC is a predictor of the incidence of complications after thoracoscopic lobectomy in children with CLM.

Published: August 2022

Background

Stapled haemorrhoidopexy (SH) has resulted in a unique collection of procedural complications with postoperative mucocele a particularly rare example. This study is designed to comprehensively describe the characteristics of rectal mucocele and discuss its pathogenesis following SH surgery.

Methods

A database of patients presenting with a rectal mucocele following an SH procedure was established and studied retrospectively.

Results

Seven patients (5 males; median age 32 years, range 20–75 years) were identified. All patients complained of variable anal discomfort with 5/7 presenting with inconstant anal pain, 2 with de novo evacuatory difficulty. These cases appeared at a median time of 6 months (range 2–84 months) after SH surgery.

Conclusion

Rectal Mucocele develops when mucosal fragments become embedded and isolated under the mucosa. It is a preventable complication of SH surgery by ensuring correct purse string placement prior to stapled haemorrhoid excision.
Quality of life in childhood advanced cancer: from conceptualization to assessment with the Advance QoL tool
Authors: Avoine-Blondin Josianne , Dumont Émilie , Marquis Marc-Antoine , Duval Michel , Sultan Serge
Published: August 2022

Background

Advanced childhood cancer, a condition with no available cancer-focused treatment options, greatly impacts Quality of Life (QoL). We need appropriate assessment strategies to select adapted treatment targets, improve care and optimize communication. Our first goal was to identify the domains of patients’ QoL by combining for the first time the perspectives of patients and parents with previously collected reports in professionals. Our second goal was to develop a simple QoL assessment tool and optimize its format and content for use in the childhood advanced cancer population.

Methods

To identify QoL domains, we conducted qualitative interviews with 7 young patients (4 girls, 3 boys, aged 13 ± 4 yrs) and 9 parents (7 mothers, 2 fathers) from our treatment centre. We used inductive thematic content analysis to code and categorize respondents’ viewpoints. The first version of the tool (Advance QoL) was then drafted, and structured feedback was collected through interviews and a survey with 15 experts. We computed content validity indices.

Results

Apart from the physical, psychological, and social domains, participants insisted on four original themes: autonomy, pleasure, the pursuit of achievement, and the sense of feeling heard. This was in line with the categories found in a preliminary study involving professionals (PMID: 28137343). Experts evaluated the tool as clear, relevant, acceptable, and usable. They formulated recommendations on instructions, timeframe, and item formulations, which we implemented in the refined version.

Conclusions

Advance QoL is an innovative tool targeting key life domains in childhood advanced cancer. It is focused on preserved abilities and targets of care. The refined version is appropriate for adult respondents within families and professionals. Future studies will develop versions for young ages to collect the experience of patients themselves. This will open on future reliability, validity, sensitivity, and implementation studies.

Published: August 2022

Introduction

Insulin pump therapy represents an alternative to multiple daily injections and can improve glycemic control and quality of life (QoL) in Type 1 diabetes mellitus (T1DM) patients. We aimed to explore the differences and factors related to the T1DM-specific QoL of such patients in Latvia.

Design and methods

A mixed-method cross-sectional study on 87 adult T1DM patients included 20 pump users and 67 users of injections who participated in the quantitative part of the study; 8 pump users and 13 injection users participated in the qualitative part. Patients were invited to participate using a dedicated digital platform. Their QoL and self-management habits were assessed using specially developed questionnaires adapted to Latvian conditions. Multiple logistic regression models were built to investigate the association between social and self-management factors and patients’ QoL. In addition, qualitative analysis of answers was performed.

Results

Insulin pump users were younger, had higher incomes, and reported higher T1DM expenses than users of multiple daily injections. There were no differences in self-management between the groups; Total QoL differed at the 0.1 significance level. In fully adjusted multiple logistic regression models, the most important factor that increased Total QoL was lower T1DM-related expenses (odds ratio, OR 7.02 [95% confidence interval 1.29; 38.0]). Men and those with more years of living with T1DM had better QoL (OR 9.62 [2.20; 42.1] and OR 1.16 [1.05; 1.29], respectively), but the method of administration was not significantly associated with QoL (OR 7.38 [0.87; 62.9]). Qualitative data supported the results of quantitative analysis.

Conclusions

QoL was the main reason to use an insulin pump, while the expense was the main reason to avoid the use of it or to stop using it. Reimbursement policies thus should be considered to enable patients to choose the more convenient method for themselves.
Prevalence of venous thromboembolism and evaluation of a modified caprini risk assessment model: a single-centre, prospective cohort study involving patients undergoing lung resections for bronchiectasis
Authors: Chen Qingshan , Cai YongSheng , Zhang Zhirong , Dong Honghong , Miao Jinbai , Li Hui , Hu Bin
Published: August 2022

Background

Venous thromboembolism (VTE) is a common postoperative complication in general thoracic surgery, but the incidence of patients undergoing surgery for bronchiectasis was not known. The purpose of our study was to investigate the incidence of VTE in bronchiectasis patients undergoing lung resection and to evaluate the risk stratification effect of the modified caprini risk assessment model (RAM).

Methods

We prospectively enrolled patients with bronchiectasis who underwent lung resection surgery between July 2016 and July 2020.The postoperative duplex lower-extremity ultrasonography or(and) computed tomographic pulmonary angiography (CTPA) was performed to detect VTE. The clinical characteristics and caprini scores of VTE patients and non-VTE patients would be compared and analyzed. Univariate logistic regression was performed to evaluate whether higher Caprini scores were associated with postoperative VTE risk.In addition, We explored the optimal cutoff for caprini score in patients with bronchiectasis by using the receiver operating characteristic (ROC) curve.

Results

One hundred and seventeen patients were eligible based on the prospective study criteria. The postoperative VTE incidence was 8.5% (10/117). By comparing the clinical characteristics and Caprini scores of VTE and non-VTE patients, the median preoperative hospitalization (7 vs 5 days, P = 0.028) and Caprini score (6.5 vs 3,P < 0.001) were significantly higher in VTE patients. In univariate logistic regression, a higher Caprini score was associated with higher odds ratio (OR) for VTE of 1.7, 95% confidence interval (CI) was from 1.2 to 2.5 (P = 0.001), C-statistics was 0.815 in the modified caprini RAM for predicting VTE. In a multivariable analysis adjusting for preoperative hospitalization, a higher Caprini score was associated with higher odds OR for VTE of 1.8 (95%CI: 1.2–2.6, P = 0.002), C-statistics was 0.893 in the caprini RAM for predicting VTE. When taking the Caprini score as 5 points as the diagnostic threshold, the Youden index is the largest.

Conclusions

The postoperative VTE incidence in patients undergoing lung resection for bronchiectasis was 8.5%.The modified caprini RAM effectively stratified bronchiectasis surgery patients for risk of VTE and showed excellent predictive power for VTE. The patients with postoperative caprini scores = 5, should be recommended to take positive measures to prevent postoperative VTE.

Developing key performance indicators for the Canadian chiropractic profession: a modified Delphi study
Authors: Blanchette Marc-André , Mior Silvano , Thistle Shawn , Stuber Kent
Published: August 2022

Background

The purpose of this study is to develop a list of performance indicators to assess the status of the chiropractic profession in Canada.

Method

We conducted a 4-round modified Delphi technique (March 2018–January 2020) to reach consensus among experts and stakeholders on key status indicators for the chiropractic profession using online questionnaires. During the first round, experts suggested indicators for preidentified themes. Through the following two rounds, the importance and feasibility of each indicator was rated on an 11-point Likert scale, and their related potential sources of data identified. In the final round, provincial stakeholders were recruited to rate the importance of the indicators within the 90th percentile and identified those most important to their organisation.

Results

The first round generated 307 preliminary indicators of which 42 were selected for the remaining rounds, and eleven were preferentially selected by most of the provincial stakeholders. Experts agreed the feasibility of all indicators was high, and that data could be collected through a combination of data obtained from professional liability insurance records and survey(s) of the general population, patients, and chiropractors.

Conclusions

A set of performance indicators to assess the status of the Canadian chiropractic profession emerged from a scientific and stakeholder consensus.
To tape or not to tape: annular ligament (pulley) injuries in rock climbers—a systematic review
Authors: Larsson Robin , Nordeman Lena , Blomdahl Christina
Published: August 2022

Background

Popularity of rock climbing is steadily increasing. With its inclusion in the Olympic Games this will likely continue. Injuries from rock climbing are also increasing. The most common injury is to the flexor pulley system, consisting of the finger flexors and five annular ligaments (pulleys). Treatment of this injury includes taping of affected fingers, but evaluation of this treatment was previously lacking. The aim of this review was therefore to assess whether taping is associated with better outcomes than non-taping. A secondary aim was to present treatment recommendations or areas for future research.

Methods

Systematic searches of PubMed, Scopus, SPORTDiscus, Cochrane Library, PEDro and CINAHL. Free text searches of Google Scholar. Citation searching. No restrictions to language, date of publication or study design. Included studies were assessed using Cochrane scale for clinical relevance, by two independent authors. Results were presented in narrative synthesis. Certainty of evidence (GRADE) was assessed by three authors. Review was done according to PICO-protocol and reported according to PRISMA-guidelines.

Results

After removing duplicates, 595 records were identified. Eight studies and one case report (in nine articles, one poster) were included, consisting of 206 rock climbers, four non-climbers, 23 pairs of cadaver hands. Clinical relevance ranged from 0 to 5 (median 2). Evidence of low to moderate certainty suggests that taping might reduce bowstringing of the finger flexor tendons by 15–22%. Evidence regarding pain, time for return to sports, shearing forces against pulleys, pulley ruptures and maximum voluntary contraction (MVC) were all regarded as “very low”, “very low to low” or “low”, and were not considered reliable. Evidence of moderate certainty suggests that taping has no effect on MVC or muscle activation in uninjured rock climbers. No adverse effects of taping were reported.

Conclusion

Low to moderate evidence suggests that taping might reduce bowstringing of the finger flexor tendons. Moderate evidence suggests that taping has no effect on MVC or muscle activation in uninjured climbers. For other outcomes more studies evaluating the effects of taping are needed.

Authors: Abu-Hanna Jeries , Patel Jigisha A. , Anastasakis Evangelos , Cohen Richard , Clapp Lucie H. , Loizidou Marilena , Eddama Mohammad M. R.
Published: August 2022

Histone 3 lysine 27 (H3K27) demethylation constitutes an important epigenetic mechanism of gene activation. It is mediated by the Jumonji C domain-containing lysine demethylases KDM6A and KDM6B, both of which have been implicated in a wide myriad of diseases, including blood and solid tumours, autoimmune and inflammatory disorders, and infectious diseases. Here, we review and summarise the pre-clinical evidence, both in vitro and in vivo, in support of the therapeutic potential of inhibiting H3K27-targeting demethylases, with a focus on the small-molecule inhibitor GSK-J4. In malignancies, KDM6A/B inhibition possesses the ability to inhibit proliferation, induce apoptosis, promote differentiation, and heighten sensitivity to currently employed chemotherapeutics. KDM6A/B inhibition also comprises a potent anti-inflammatory approach in inflammatory and autoimmune disorders associated with inappropriately exuberant inflammatory and autoimmune responses, restoring immunological homeostasis to inflamed tissues. With respect to infectious diseases, KDM6A/B inhibition can suppress the growth of infectious pathogens and attenuate the immunopathology precipitated by these pathogens. The pre-clinical in vitro and in vivo data, summarised in this review, suggest that inhibiting H3K27 demethylases holds immense therapeutic potential in many diseases.
Raters’ perceptions of rating scales criteria and its effect on the process and outcome of their rating
Authors: Heidari Nasim , Ghanbari Nasim , Abbasi Abbas
Published: August 2022

It is widely believed that human rating performance is influenced by an array of different factors. Among these, rater-related variables such as experience, language background, perceptions, and attitudes have been mentioned. One of the important rater-related factors is the way the raters interact with the rating scales. In particular, how raters perceive the components of the scales to further plan their scoring seems important. For this aim, the present study investigated the raters’ perceptions of the rating scales and their subsequent rating behaviors for two analytic and holistic rating scales. Hence, nine highly experienced raters were asked to verbalize their thoughts while rating student essays using IELTS holistic scale and the analytic scale of ESL Composition Profile. Upon analyzing the think-aloud protocols, four themes emerged. The findings showed that when rating holistically, the raters either referred to the holistic scale components to validate their ratings (validation) or had a pre-evaluation reading to rate in a more reliable way (dominancy). In analytic rating, on the other hand, the raters used a pre-evaluation scale reading in order to keep the components and their criteria to memory to evaluate the text more accurately (dominancy) or regularly moved between the text and the scale components to assign a score (oscillation). Furthermore, the results of a Wilcoxon signed-rank test showed that when using the holistic and analytic rating scales, the raters assigned significantly different scores to the texts. On the whole, the results revealed that the way the raters perceived the scale components will affect their judgement of the texts. The study also provides several implications for rater training programs and EFL writing assessment.
Research on the mechanism of emotional design in Chinese cultural and creative products
Authors: Yu Lei , Feng Xin , Wang Jingya , Kong Weixin , Chen Weiqing
Published: August 2022

Motivation

The empowerment of design for cultural and creative products in the digital media era is further amplified by social media platforms,its emotional and subconscious impact on users is important and profound. The development of the network economy has promoted this trend. At the same time, this trend has further promoted the growth of cultural and creative products market. However, too obscure appearance design can hardly arouse the resonance of different cultural groups in a short time. As an effective method to bridge the cultural gap between consumers, emotional design has become an important driving force for the development of cultural and creative products.

Purpose

The purpose of this study is to understand the impact of emotional factors on the willingness and preferences of ordinary consumers to buy Chinese cultural and creative products, and to further explore whether there are cognitive differences between the emotional design standards defined and promoted by professionals and the excellent design recognized by consumers according to their life experience and personal subjective emotional preferences.

Design/methodology/approach

Through the construction of the emotional design model, this study selects four award-winning products in the cultural and creative product design competition and four commercial products with high sales volume in the online stores as research cases. Through 176 valid questionnaires conducted by non-professionals, this study makes an analysis by using the structural equation.

Conclusions

The study found that consumers' preference and purchase intention of Chinese cultural and creative products are affected by emotional design standards, but the impact results depend on the interaction of many factors. At the same time, there are also significant differences in cognitive paths between them.
Wearable CNTs-based humidity sensors with high sensitivity and flexibility for real-time multiple respiratory monitoring
Authors: Kim Han-Sem , Kang Ji-Hye , Hwang Ji-Young , Shin Ueon Sang
Published: August 2022

Sensors, such as optical, chemical, and electrical sensors, play an important role in our lives. While these sensors already have widespread applications, such as humidity sensors, most are generally incompatible with flexible/inactive substrates and rely on conventional hard materials and complex manufacturing processes. To overcome this, we develop a CNT-based, low-resistance, and flexible humidity sensor. The core–shell structured CNT@CPM is prepared with Chit and PAMAM to achieve reliability, accuracy, consistency, and durability, resulting in a highly sensitive humidity sensor. The average response/recovery time of optimized sensor is only less than 20 s, with high sensitivity, consistent responsiveness, good linearity according to humidity rates, and low hysteresis (− 0.29 to 0.30 %RH). Moreover, it is highly reliable for long-term (at least 1 month), repeated bending (over 15,000 times), and provides accurate humidity measurement results. We apply the sensor to smart-wear, such as masks, that could conduct multi-respiratory monitoring in real-time through automatic ventilation systems. Several multi-respiratory monitoring results demonstrate its high responsiveness (less than 1.2 s) and consistent performance, indicating highly desirable for healthcare monitoring. Finally, these automatic ventilation systems paired with flexible sensors and applied to smart-wear can not only provide comfort but also enable stable and accurate healthcare in all environments.
Two tales of platform regimes in China’s food-delivery platform economy
Authors: Wei Haitao , Zhang Luyang , Deng Peipei , Li Guohui
Published: August 2022

This article brings the often-overlooked concept of the labor regime back to the study of China’s food-delivery platform workers. Two tales of platform regimes emerge: individualized platform despotism and bureaucratized platform despotism, which apply to crowdsourcing couriers and dedicated delivery couriers, respectively. This study compares these two types of platform regimes in terms of their institutional foundation and labor organization. Despite different institutional arrangements and labor organization, both types of food-delivery couriers belong to a despotic platform regime revealing workers’ subordination to the platform. In conclusion, it discusses the implications and limitations of this study.
Concomitant palonosetron ameliorates cisplatin-induced nephrotoxicity, nausea, and vomiting: a retrospective cohort study and pharmacovigilance analysis
Authors: Takemura Miho , Ikemura Kenji , Kondo Masayoshi , Yamane Fumihiro , Ueda Mikiko , Okuda Masahiro
Published: August 2022

Background

Cisplatin (CDDP)-induced nephrotoxicity is the most important complication of CDDP treatment. 5-Hydroxytryptamine type 3 receptor antagonists (5-HT3RAs) are widely used to prevent chemotherapy-induced nausea and vomiting (CINV). However, in patients with the triple antiemetic (neurokinin-1 receptor antagonist, 5-HT3RA, and dexamethasone) therapy, the advantage of palonosetron in comparison with other 5-HT3RAs on CDDP-induced nephrotoxicity and CINV remains unclear. In the present study, we investigated the effect of palonosetron on CDDP-induced nephrotoxicity and CINV in patients with the triple antiemetic therapy by a retrospective cohort study and a pharmacovigilance analysis.

Methods

We retrospectively analyzed the effect of 5-HT3RAs on the development of nephrotoxicity and CINV in 110 patients who received CDDP, fluorouracil, and triple antiemetic therapy for the treatment of esophageal cancer. Moreover, the effect of 5-HT3RAs on CDDP-induced nephrotoxicity was validated in patients with the triple antiemetic therapy using the Japanese Adverse Drug Event Report (JADER) database.

Results

In a retrospective study, the incidence of nephrotoxicity (≥ grade 1) in patients receiving palonosetron (18%) was significantly lower than that in patients receiving ramosetron (another 5-HT3RA) (36%, p = 0.044). Moreover, severe nephrotoxicity ≥ grade 3 was observed in one patient treated with ramosetron, whereas hematological toxicity was comparable between the two groups (p = 0.553). Furthermore, the incidence rate of CINV within 120 h following CDDP administration in patients treated with palonosetron (18%) was significantly lower than that in patients receiving ramosetron (39%, p = 0.026). JADER database analyses revealed that the reporting odds ratio of palonosetron for CDDP-induced acute kidney injury was 0.282 (95% confidence interval: 0.169–0.472).

Conclusions

The findings of the present study suggested a greater potential of palonosetron against CDDP-induced nephrotoxicity and CINV than other 5-HT3RAs in patients with the triple antiemetic therapy.
Abnormal growth of a pleomorphic leiomyosarcoma originating from the mesenteric vein associated with poor outcome after curative-intent resection: a case report
Authors: Otabe Masaya , Abe Tomoyuki , Sumi Yusuke , Yonehara Shuji , Noriyuki Toshio , Nakahara Masahiro
Published: August 2022

Background

A leiomyosarcoma (LMS) is a rare tumor that mainly originates from the urinary tract and digestive system; however, non-visceral organ-derived patterns are rare. Herein, we report that a vessel-derived pleomorphic LMS (PLMS) originating from the mesenteric vein has a poor prognosis even after curative-intent surgery.

Case presentation

The patient was a 41-year-old woman with no relevant medical history. The patient presented with abdominal pain and an abnormal bulge on the left lower abdomen. Magnetic resonance imaging revealed a large tumor occupying the left abdomen. Enhanced computed tomography revealed a bulky tumor with a maximum size of 13 × 13 cm with impending rupture, and a small amount of ascites was detected around the tumor. As the tumor directly invaded the small intestine and descending colon, left hemicolectomy and partial resection of the small intestine were performed. The patient was discharged on postoperative day 10, without any complications. On histopathological analysis, the tumor was diagnosed as a vessel-derived LMS with a pleomorphic pattern. The patient died due to disseminated intravascular coagulation because generalized peritonitis was induced by the super-early recurrence of the tumor 2 months after the surgery.

Conclusions

Regardless of curative-intent surgery for a vessel-derived PLMS, super-early local recurrence and distant metastasis were observed. A vessel-derived PLMS requires further investigation to determine its characteristics and therapeutic strategies to improve long-term prognosis.

Published: August 2022

Background

Delayed onset of colorectal liver metastasis (CRLM) > 5 years after primary colorectal surgery is rare. Herein, we report a case of delayed-onset CRLM that occurred 10 years after primary surgery, for which laparoscopic hepatectomy was performed.

Case presentation

A 68-year-old man was admitted to the hospital. His medical history revealed double colon cancer detected 10 years ago, for which laparoscopic colectomy was performed. The pathological tumor–node–metastasis stages were stages I and II. Thereafter, oral floor cancer occurred 7 years after the primary surgery and was curatively resected. The annual follow-up with positron emission tomography–computed tomography (CT) identified a tumor at segment 7/8 (S7/8) of the liver with an abnormal accumulation of fluorodeoxyglucose. Dynamic CT showed a 23-mm tumor, with ring enhancement in the early phase. Magnetic resonance imaging with gadolinium–ethoxybenzyl-diethylenetriamine penta-acetic acid demonstrated that the tumor had high intensity in T2 weighted sequences and low intensity in the hepatobiliary phase. With a preoperative diagnosis of intrahepatic cholangiocarcinoma or delayed liver metastasis, laparoscopic S7/8 partial resection was performed. The operative time was 324 min, and the intraoperative bleeding volume was 35 mL. The patient was discharged on day 15 without any postoperative complications. Upon histopathological examination, the final diagnosis was CRLM. The patient has survived for 1 year without any recurrence.

Conclusions

It is important to pay attention to the occurrence of delayed-metachronous CRLM.
Food advertisement influences food decision making and not nutritional status: a study among university students in Ghana
Authors: Kalog Gabriel Libienuo Sowley , Kasim Faiza , Anyebuno Bernice , Tei Sandra , Kubuga Clement Kubreziga , Mogre Victor , Aryee Paul Armah
Published: August 2022

Background

Consumers are exposed to a wide range of advertisements through different channels daily, which tends to have an influence on their food decision making. The aim of this study was to evaluate the different forms of food advertisements students are exposed to on campus and how they influence their food choices and nutritional status.

Methods

This cross-sectional study was conducted to find out the influence of different forms of food advertisements on students’ food choices and nutritional status. A self-reported semi-structured questionnaire was used to elicit responses from 367 students. About 51.5% of the students were females and 48.5% males. Body Mass index (BMI) was derived from weight and height measured according to standard procedures. Data was analysed and presented as frequencies and percentages. Chi-square was used to determine association between categorical variables (socio-demographic characteristics, food choices and nutritional status).

Results

The students reported ‘use of internet’ (58.9%) as the main source of food advertisement on campus, followed by television (21.0%). A large number of students (74.9%) were affirmative about food advertisements influencing their food decision making. Those with poor nutritional status (underweight, overweight and obese) were more likely to patronize sugar sweetened beverages (10.1%) as compared to fruits and vegetables (1.4%). There was statistical significance (p = 0.003) for type of food patronized due to advertisement and the source of advertisement. However, there was no statistical significance (p = 0.832) for type of food patronized due to advertisement and BMI of students.

Conclusion

Owing to the increased patronage of internet and television as channels of food advertisements by students, policy makers should prioritize the designing and implementation of intervention programmes through these channels that would influence healthy food decision making and promote consumption of nutrient rich foods. As this population has high self-reported advertisements’ influence on food choices, it is vital to investigate further the influence of contextual cues such as environment and advertisement on their eating habits and dietary patterns.
Surgical ciliated cyst of the mandible after orthognathic surgery: a case report with review of the literature
Authors: Youn Sungbin , Oh Hyun Jun , Yoon Hye-Jung , Seo Byoung-Moo
Published: August 2022

Background

Surgical ciliated cysts, also known as postoperative maxillary cysts or implantation cysts, occur mainly in the posterior maxilla after radical maxillary sinus surgery; they rarely develop in the mandible. They are thought to occur when the sinonasal epithelium is infiltrated by a surgical instrument during surgery or as a result of transplantation of bone or cartilage with respiratory epithelium attached.

Case presentation

We report a case in which a surgical ciliated cyst developed in the anterior part of the mandible, presumably as a result of bimaxillary orthognathic surgery and genioplasty performed 24 years earlier. We then review the few similar cases reported in the literature.

Conclusion

Surgical ciliated cysts in the mandible are extremely rare, but they could occur after simultaneous surgery on the maxilla and mandible, even decades later. To prevent surgical ciliated cysts in the mandible, we recommend that the surgical instruments, especially the saw blade used during bimaxillary surgery, be new or cleaned and that previously placed plates and screws be removed at an appropriate time.
State of the Art Physiotherapist-Led Approaches to Safe Aging in Place
Authors: Wilson Christopher M. , Arena Sara K. , Boright Lori E.
Published: August 2022

Introduction

Safe aging in place (SAIP) is when an older adult can successfully and comfortably remain in their home despite increasing barriers, including falls. Various physical, medical, psychological, and psychosocial factors may individually or cumulatively impact an older adult’s ability to safely age in place. Physiotherapists should assess not only items traditionally considered within their scope of practice but should select efficient and effective outcome measures to quantify other domains of health. A comprehensive geriatric assessment (CGA) is an evidence-based clinical assessment which identifies medical, psychosocial, and functional limitations of an older person. The CGA is useful to dictate individualized exercise/intervention prescription to address identified areas of increased risk.

Purpose and importance to practice

The purpose of this Masterclass is to describe key screening, assessments, and interventions to facilitate SAIP and to provide overviews of currently available programming and care delivery models applicable to physiotherapist practice.

There are a wide variety of outcome measures and interventions that vary in depth, validity, and reliability. Measures selected for inclusion in this Masterclass were chosen based upon their clinical utility with respect to time and resource constraints and ease of administration during a comprehensive assessment for SAIP in community-dwelling older adults. Measures recommended for assessing physical function were the Short Physical Performance Battery, the Timed-Up-and-Go, the 30 second chair rise test, and the Four Test Balance Scale. Additionally, measures from the heath domain (e.g., Functional Comorbidity Index) and the environmental domain (e.g., Home FAST) are recommended. Relative to interventions, the Otago Exercise Program, motivational interviewing, home modifications, and leveraging technology are recommended. Partnerships with community-facing organizations facilitate utilization of resources for sustainable SAIP. The Home-based Older Person Upstreaming Prevention Physical Therapy (HOP-UP-PT) program is one approach led by physiotherapists framed in the screening, assessments, and interventions discussed in this Masterclass with strong scientific grounding.

Conclusion

Programs integrating both community and healthcare approaches have the strongest evidence for their utility; however, implementation for these preventative approaches are lagging behind the increased need due to the substantial population growth of those over 65 years.
PLGA-based nanoparticles for the treatment of cancer: current strategies and perspectives
Authors: Alvi Maria , Yaqoob Azka , Rehman Kanwal , Shoaib Syed Muhammad , Akash Muhammad Sajid Hamid
Published: August 2022

Research on cancer treatment is always of great importance because of the extensive and difficult treatment options and side effects of chemotherapeutic agents. Due to this, novel techniques for cancer treatment are the need of the day. Nowadays, nanotechnology is of great interest for its applications as diagnostic tools, theragnostic, contrasting agents, and vehicles for delivering drugs. Nanoparticles (NPs) are made up of biocompatible and biodegradable polymers that improve the pharmacokinetic and pharmacodynamic properties of drugs, reduce side effects, improve stability, prolong the release of drug, and reduce the dosing frequency. Poly (lactic-co-glycolic acid) (PLGA) is FDA-approved synthetic polymer which can be used to formulate NPs that can be targeted to a specific site for the safe and effective delivery of drugs. PLGA-based NPs can be used for a variety of cancer therapies including tumor-targeted drug delivery, gene therapy, hyperthermia, and photodynamic therapy. This article discusses the method of preparation, characterization, encapsulation of chemotherapeutic drugs, effect of physicochemical properties of PLGA- based NPs, and how we can exploit these aspects through various methods of preparation for drug loading, biodistribution, target specificity, and their use in cancer treatment. Along with these targeting strategies, gene therapy, cancer immunotherapy, and various applications have also been discussed.

Background

Continuous positive airway pressure (CPAP) is a common mode of respiratory support used in neonatal intensive care units. In preterm infants, nasal CPAP (nCPAP) therapy is often delivered via soft, biocompatible nasal mask suitable for long-term direct skin contact and held firmly against the face. Limited sizes of nCPAP mask contribute to mal-fitting related complications and adverse outcomes in this fragile population. We hypothesized that custom-fit nCPAP masks will improve the fit with less skin pressure and strap tension improving efficacy and reducing complications associated with nCPAP therapy in neonates.

Methods

After IRB approval and informed consent, we evaluated several methods to develop 3D facial models to test custom 3D nCPAP masks. These methods included camera-based photogrammetry, laser scanning and structured light scanning using a Bellus3D Face Camera Pro and iPhone X running either Bellus3D FaceApp for iPhone, or Heges application. This data was used to provide accurate 3D neonatal facial models. Using CAD software nCPAP inserts were designed to be placed between proprietary nCPAP mask and the model infant’s face. The resulted 3D designed nCPAP mask was form fitted to the model face. Subsequently, nCPAP masks were connected to a ventilator to provide CPAP and calibrated pressure sensors and co-linear tension sensors were placed to measures skin pressure and nCPAP mask strap tension.

Results

Photogrammetry and laser scanning were not suited to the neonatal face. However, structured light scanning techniques produced accurate 3D neonatal facial models. Individualized nCPAP mask inserts manufactured using 3D printed molds and silicon injection were effective at decreasing surface pressure and mask strap pressure in some cases by more than 50% compared to CPAP masks without inserts.

Conclusions

We found that readily available structured light scanning devices such as the iPhone X are a low cost, safe, rapid, and accurate tool to develop accurate models of preterm infant facial topography. Structured light scanning developed 3D nCPAP inserts applied to commercially available CPAP masks significantly reduced skin pressure and strap tension at clinically relevant CPAP pressures when utilized on model neonatal faces. This workflow maybe useful at producing individualized nCPAP masks for neonates reducing complications due to misfit.
Neuromodulation for temporal lobe epilepsy: a scoping review
Authors: Ebrahim Ashabilan Abdikarim , Tungu Alexander
Published: August 2022

Temporal lobe epilepsy (TLE) is difficult to treat as it is often refractory to treatment. Apart from traditional medical treatment, surgical resection is also a choice of treatment, but it may be associated with significant cognitive deficits. ‌As a result, treatment strategies using targeted and adjustable stimulation of malfunctioning brain circuits have been developed. These neuromodulatory therapies using approaches of electric and magnetic neuromodulation are already in clinical use for refractory epilepsy while others such as optogenetics, chemo-genetics and ultrasound modulation are being tested in pre-clinical TLE animal models. In this review, we conducted an in-depth literature search on the clinically available neuromodulatory approaches for TLE, focusing on the possible mechanism of action and the clinical outcomes including adverse effects. Techniques that are currently explored in preclinical animal models but may have therapeutic applications in future are also discussed. The efficacy and subsequent adverse effects vary among the different neuromodulatory approaches and some still have unclear mechanisms of action in TLE treatment. Further studies evaluating the benefits and potential limitations are needed. Continued research on the therapeutic mechanisms and the epileptic brain network is critical for improving therapies for TLE.

Background

Due to the high prevalence of HIV, HIV-associated lymphoma (HAL) is a common malignancy in South Africa. However, there is a paucity of literature on HAL from this region. The objective of this study was to profile the clinical characteristics and outcome of CD20-positive HAL treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), with or without rituximab (R), from a single center in KwaZulu -Natal, South Africa.

Methods

Retrospective chart review of adult patients treated from 2006 to 2018 for HIV-associated CD20-positive lymphoma. The clinical characteristics, complete response (CR), and 2-year overall survival (OS) are described.

Results

The analysis included 102 patients, 54% females, median age of 39 years, and median CD4 cell count of 196 cells/μL. Bone marrow involvement was noted in 5%. Eighty-six percent of the cohort received concomitant antiretroviral therapy and chemotherapy, 76% of the CHOP group, and 92% of the R-CHOP group. Overall, a CR was seen in 55% (95% CI 45%; 65%), with a 2-year OS of 59% (95% CI 50%, 69%). A CR was attained in 46% on CHOP and 64% on R-CHOP, with a 2-year disease-free survival (DFS) for CHOP of 42% and 50% for R-CHOP.

Conclusion

Although the clinical characteristics and laboratory findings are similar to other higher-income cohorts, there was a difference in gender and incidence of marrow involvement. The low incidence of marrow involvement has prompted more routine use of immunohistochemistry and flow cytometry in staging marrows of HAL locally. Further randomized studies are required for the establishment of locally validated, cost-effective treatment guidelines.

Natural killer T (NKT) cells activated with the glycolipid ligand α-galactosylceramide (α-GalCer) stimulate a wide variety of immune cells that enhance vaccine-mediated immune responses. Several studies have used this approach to adjuvant inactivated and subunit influenza A virus (IAV) vaccines, including to enhance cross-protective influenza immunity. However, less is known about whether α-GalCer can enhance live attenuated influenza virus (LAIV) vaccines, which usually induce superior heterologous and heterosubtypic immunity compared to non-replicating influenza vaccines. The current study used the swine influenza challenge model to assess whether α-GalCer can enhance cross-protective immune responses elicited by a recombinant H3N2 LAIV vaccine (TX98ΔNS1) encoding a truncated NS1 protein. In one study, weaning pigs were administered the H3N2 TX98ΔNS1 LAIV vaccine with 0, 10, 50, and 100 μg/kg doses of α-GalCer, and subsequently challenged with a heterologous H3N2 virus. All treatment groups were protected from infection. However, the addition of α-GalCer appeared to suppress nasal shedding of the LAIV vaccine. In another experiment, pigs vaccinated with the H3N2 LAIV, with or without 50 μg/kg of α-GalCer, were challenged with the heterosubtypic pandemic H1N1 virus. Pigs vaccinated with the LAIV alone generated cross-reactive humoral and cellular responses which blocked virus replication in the airways, and significantly decreased virus shedding. On the other hand, combining the vaccine with α-GalCer reduced cross-protective cellular and antibody responses, and resulted in higher virus titers in respiratory tissues. These findings suggest that: (i) high doses of α-GalCer impair the replication and nasal shedding of the LAIV vaccine; and (ii) α-GalCer might interfere with heterosubtypic cross-protective immune responses. This research raise concerns that should be considered before trying to use NKT cell agonists as a possible adjuvant approach for LAIV vaccines.
Geochemical transformation of tuffaceous materials in tight sandstone and its significance for reservoir reconstruction: A case study from the Taiyuan and Shihezi Formation in Dingbei area, Ordos Basin

Combined with thin sections and electronic probe microanalyzer (EPMA) analysis, we studied the effect of the chemical composition of tuffaceous materials on the quality of sandstone reservoir in the Dingbei area. Analysis of 100 thin sections from five drilled wells indicates that the tuffaceous materials in sandstones from the Taiyuan and Shihezi Formation are common due to the volcanic eruptions. There are three types of tuffaceous materials in the sandstone: intermediate-basic type, intermediate-acid type, and mixed type. Seven thin sections were selected to analyze the chemical elements of tuffaceous materials by EPMA, with 3–8 test points on each thin section. The results indicate a clear decline in most major elements except for SiO2 and Al2O3. The elemental differentiation of tuffaceous sandstone is largely controlled by the activity of the diagenetic system. Under the slow-moving fluid, the active elements such as K, Na, Ca, Mg, and Fe are lost, and Si and Al are enriched. The SiO2 contents of EPMA results are up to 42%. Under the strong-flow fluid, Si and Al can be transferred to precipitate the kaolinites. In the closed diagenetic system, the contents of active elements such as Na and K are high. Dissolution or alteration of tuffaceous materials with different types under the acid fluid is one of the reasons for the generation of heterogeneous reservoirs. The intermediate-acid tuffaceous materials with high SiO2 content experience transformation without dissolution. The mixed tuffaceous materials are mainly transformed into kaolinite to form intercrystalline pores. Due to a large number of soluble components in the intermediate-basic tuffaceous materials, a large number of secondary pores are developed.
