Published: June 2024

Objective: To evaluate, in patients with a prior history of cesarean delivery undergoing cervical ripening with a double balloon catheter, whether removal of device after six hours versus twelve hours would result in shorter time to delivery.

Methods: A before-and-after study was performed after a practice change occurred November 2020, at which time the standard duration of double cervical balloon catheter placement during induction was changed from twelve hours to six hours. Data was collected via retrospective electronic chart review. Inclusion criteria included singleton pregnancy, history of prior cesarean delivery, fetus in cephalic presentation upon admission, and cervical ripening accomplished with a double balloon catheter. Patients with multiple gestation pregnancy, those with more than one balloon catheter placed during labor, and those being induced for fetal demise were excluded from this study. Primary outcome was time from balloon placement to delivery. Secondary outcomes included rates of cesarean delivery and rates of maternal intraamniotic infection. Uterine rupture was a safety outcome. Kaplan-Meier curves compared median times to delivery between the groups. A Cox proportional-hazards model was used to adjust for time of balloon placement, number of previous vaginal deliveries, and co-medications used.

Results: From November 2018 to November 2022, 210 patients with a prior history of cesarean delivery received a double balloon catheter for cervical ripening during their trial of labor. After chart review, 189 patients were found to be eligible. The patients were separated into pre- and post-policy change groups (n=91 and 98, respectively). The median time to vaginal delivery for the pre-group was 28 hours (95% CI: 26, 35) and 25 hours (95% CI: 23, 29) for those in the post-group (p-value 0.052). After adjusting for dilation at time of balloon placement, number of previous vaginal deliveries, and co-medication, the estimated hazard ratio for successful vaginal delivery post-policy change was 1.89 (95% CI: 1.27, 2.81). There were no differences in rates of secondary outcomes.

Conclusion: In patients with prior cesarean delivery undergoing mechanical cervical ripening with a double balloon catheter, planned removal at 6 hours compared to 12 hours may result in shorter time to delivery without increasing rates of cesarean and intraamniotic infection. Shortened time to delivery has been known to reduce maternal and perinatal morbidity, such as infection, hemorrhage, and cesarean delivery as well as conserve hospital resources and improve patient satisfaction. Decreasing duration of balloon placement in this population should be considered.

Authors: Pan Songzhe , Wang Ning , Lin Yuyun , Tang Jianhao
Published: June 2024

Since 2019, China has begun to vigorously implement a garbage sorting system across the country, with Shanghai being the first city to fully implement garbage sorting. For example, residents do not have a strong sense of classification and lack of classification knowledge, resulting in low classification accuracy. The management of the wharf is relatively loose, and the garbage collection, transportation and treatment links sometimes fail to strictly distinguish between various types of garbage, which affects the classification effect. Waste collection facilities are rudimentary, and sorting labels may not be uniform and oversimplified, which is not conducive to fine sorting. Therefore, it is urgent to solve the problem of garbage classification and become an urgent problem for all countries to study. The problem of sorting valuable garbage after garbage collection. The rapid development of deep learning provides the technical demand for intelligence. In this paper, the YOLOV8 algorithm is used to train the garbage classification model, and about 10,000 custom garbage datasets with 4 categories are used to classify food waste, hazardous waste, recyclable waste and other waste. In this paper, methods such as 0s, pandas, and numpy are used in Python programming. For model deployment, models can be deployed using trained weight files and configuration files, and models can be integrated into tools such as OpenCV, TensorFlow, etc., for real-time detection or integration into other applications.

Authors: Cao Shihao
Published: June 2024

A good eco-environment is a fundamental public good and the most inclusive form of well-being. Scientifically designing an effective environmental policy instrument system to improve eco-environmental quality is a common concern of the government and academia. Based on data from 31 provinces in China, this paper explores practical approaches to improve eco-environmental quality from the perspective of regional endowment heterogeneity. First, GIS is used to measure changes in eco-environmental quality from 2015 to 2020, and then the fuzzy-set qualitative comparative analysis is used to assess the configuration influence of environmental policy instruments. The results show that no single environmental policy instrument can constitute a necessary condition for improving eco-environmental quality; There are six paths to improve eco-environmental quality in the four regions of China. Different regional endowments lead to different eco-environmental quality improvement approaches, and the rights transaction of ecological resources is the most common environmental policy instrument. This study provides a reference for designing heterogeneous and effective systems of environmental policy instruments to improve eco-environmental quality in different regions.

Acceptance of food allergic children in Japanese childcare facilities
Authors: Shimazaki Keiko , Tsukasaki Keiko , Kyota Kaoru , Itatani Tomoya
Published: June 2024

Background:

Food allergy management systems are important for childcare facilities to accept children with food allergies prescribed epinephrine (epinephrine-treated children). The relationship between the food allergy management system of a childcare facility and the willingness of children attending the facility to accept epinephrine is unclear. We believe that childcare facilities that cooperate with local health and medical institutions are more willing to accept children receiving epinephrine.

Objective:

This study aimed to clarify the actual situation of epinephrine acceptance in children attending childcare facilities across Japan and the factors associated with their willingness to accept them.

Methods:

Between May and June 2021, 686 childcare facilities across Japan were selected and surveyed. To analyze the factors related to the willingness to accept epinephrine children attending childcare facilities, the facilities were classified into 2 groups, “willingness to accept” and “no willingness to accept,” and their attributes and characteristics, food allergy management system, cooperation with relevant organizations and ability to cooperate were compared by univariate analysis.

Results:

A questionnaire-based survey of 162 centers revealed that 18.2% of the centers had accepted children receiving epinephrine and 74.7% were willing to accept them. There was a significant association between the willingness to accept epinephrine in children and satisfaction with the food allergy management system, availability of childcare consulting agencies, and ability to work with healthcare organizations, which differed.

Conclusion:

The results highlight the importance of strengthening the management system of facilities and cooperating with relevant institutions for epinephrine children to live safely in the community.

Published: June 2024

Background:

The importance of IL-37 and downstream signal in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) demanding further investigation.

Objective:

We sought to address the potential importance of the IL-37-IL-1R8 axis in regulating inflammatory response in patients with CRSwNP.

Methods:

Nasal polyp (NP) tissues and control sinonasal tissues were obtained from adult CRSwNP, chronic rhinosinusitis without nasal polyps patients and healthy control subjects. The mRNA and protein levels of IL-37 and IL-1R8 in nasal tissues were examined by using quantitative PCR, immunohistochemical staining, and immunoblotting. In addition, the regulation of IL-1R8 expression was evaluated in human nasal epithelial cells (HNECs) in the presence of different stimuli.

Results:

The mRNA and protein levels of IL-37 and IL-1R8 were significantly elevated in nasal polyps compared with that in control tissues. IL-37 and IL-1R8 were mainly distributed in the epithelial layer and lamina propria of tissues. IL-1R8 mRNA level in nasal polys was negatively associated with eosinophil and neutrophil infiltration, as well as endoscopic score and computed tomography score. Moreover, the mRNA expression of IL-1R8 in HNECs was significantly increased by toll-like receptor agonists, but significantly inhibited by proinflammatory cytokines, which can be rescued by using steroid (DEX).

Conclusion:

Our findings showed that enhanced IL-37-IL-1R8 axis in NP tissues was negatively associated with inflammatory and clinical severity of CRSwNP patients, which could be considered as a future therapeutic target in CRSwNP patients.

The current study describes the morphological and histological appearance of the liver of the spiny dogfish Squalusacanthais, which is classified as Class: Chondrichthyes, Subclass: Elasmobranchi. Morphologically, the liver was observed as large, and consists of two symmetrical lobes connected from the upper side, and the gallbladder was observed in the right lobe. Histologically, liver sections were prepared with H&E stain, and examined with a light microscope. Hepatic parenchyma was surrounded by a capsule of connective tissue and primarily composed of hepatocytes. The nuclei of these cells were observed at the terminal site, with lipid droplets in the cytoplasm. Central veins were observed, surrounded by connective tissue and lined with a squamous epithelial layer. Hepatocytes were, separated by numerous blood sinusoids with connective tissue. Blood arteries were observed, surrounded by thick muscular fiber walls and narrow lumens compared to veins. The portal vein was observed, along with the artery and bile duct, surrounded by a thick connective tissue. The bile duct was surrounded by a layer of muscular fibers, lined with a simple columnar epithelial layer with clear nuclei, and a connective tissue layer. Melanin-containing cells were observed, but no hepatic lobules or connective tissue were seen between them. Additionally, Hepato-pancreatic tissue was not identified.

Forty-five adult trapped black rats (Rattus rattus), 24 males and 21 females, were dissected and examined in this study for ecto and endoparasites. Three ectoparasites were detected, namely, the flea (Xenopsallya cheopis), mites (Ornithonyssus bacoti), and tick (Ixodes spp) with 48.9%, 13.3%, and 2.2% respectively. Meanwhile, many species of endoparasites were: Entamoeba histolytica/dispar (73.3%), Entamoeba coli (31.3%), Blastocystis hominus (8.9%), Giardia lamblia (15.6), Chilomastix sp. (4.4%), a coccidia sp. (13.3%), Hymenolips nana (2.2%), Hymenolips diminuta (44.4%), and Taenia taeniaformis (6.7%), and Moniliformis moniliformis (2.2%).  Of all examined rats, 97.8 % (44/45) were found to harbor at least one parasite species with no significant differences between body weight, body length, and gender of the host with the prevalence of parasite species. Multiple infections occurred at six species per rat with different combinations of parasite infections. These results are the first records of the parasitic fauna of R. rattus in the Benghazi area.
Performance Evaluation of the Giga-bit 802.11ac Based WLANs
Authors: Bourawy Ashraf Ali , Abdalla Abdalmunam
Published: June 2024

Wireless local area networks based on the legacy 802.11-1997 standard brought about a new era in wireless communications, enabling users to utilize the Internet anytime, anywhere. About two decades later, the IEEE 802.11ac amendment was released that broke the Gigabit-Ethernet barrier for wireless local area networks (WLANs). This amendment introduced improvements to the first and second layers (PHY and MAC) of the standard. The very high throughput was accomplished by improving the modulation mechanism, adding more spatial streams, utilizing broader channels, exploiting beam-forming techniques, and allowing for better frame aggregation. In this article, a simulation evaluation is conducted to investigate the performance of the 802.11ac considering the enhancements introduced by this amendment. The main metric used in this study is the system throughput. In addition, the average delay metric is also considered for investigation. Different simulation scenarios are considered to examine the previously mentioned features and enhancements. Results showed that the system throughput of 802.11ac increases with larger channel sizes, improved modulation schemes, and more spatial streams. The frame aggregation has been indicated to be an effective mechanism for alleviating unwanted overheads, which consequently increased the overall throughput.

Authors: Ben Miloud Haifa M. , Alssabri Maha A.
Published: June 2024

The effect of winds and sea surface temperature on the concentration of chlorophyll-a, which is the primary source for phytoplankton to produce carbon through photosynthesis, is one of the climatic changes formed in the atmosphere and oceans that are the focus of current global studies. The study found a strong correlation between the concentration of chlorophyll-a and wind speed. The concentration of chlorophyll-a rises with increasing wind speed and reaches 0.85. Conversely, the relationship between sea surface temperatures and chlorophyll-a concentration is inverse, meaning that the higher the sea surface temperatures, the lower the concentration of chlorophyll-a. The inverse relationship approaches -0.798 in seawater. The intensity of chlorophyll-a concentration at sea and its relationship with wind speed and sea surface temperature explain why the percentage of the effect of variable wind speed and sea surface temperature on the concentration of chlorophyll-a is affected by (73.6%, 63.8%) on the concentration of chlorophyll-a, respectively.

Looking at creativity from an egalitarian perspective (creativity as a “property of every person”) provides the perspective of discovering a creative attitude in every person. Such an understanding of creative attitude (as independent of manifested artistic abilities, reflected in art products) is close to the processes of self-creation and self-education. At the same time, it brings to mind the assumptions of Maria Grzegorzewska, describing the qualities of a pedagogue, a teacher-educator as a person who first undertakes work on himself/herself in order to then be able to share themselves with the students. Celebrating its 40th anniversary, the Department of Special Pedagogy at the John Paul II Catholic University of Lublin currently includes 18 persons. The creative attitude of each of them contributes to the richness of the department as a space for conducting research and teaching activities. What makes the department what it is? What constitutes its richness? Who are the people who work for the Department of Special Pedagogy? In what way the creative attitude of the academic teachers contribute to the research and didactic work of the department? The purpose of this chapter is to analyze the manifestations of the creative attitude in the light of selfreflection of the academic teachers of the department. The statements were built on the basis of unfinished sentences developed for this purpose, which were intended to orient the respondents to selected aspects of their lives related to the issue of creative attitude

Published: June 2024

The present study compares the behavior of different sound types and their sources concerning distance. Experimental findings demonstrate a consistent reduction in noise levels with increasing distance from the sound origin, aligning with anticipated sound propagation patterns. Median noise level reductions are quantified, showing decreases from 72.7 dB at the source to 54.8 dB at a distance of 3 m. Pulsed sounds exhibit pronounced fluctuations and peaks at close distances, while steady and blended sounds maintain more uniform levels. An exponential model accurately characterizes the noise reduction phenomenon (R² = 0.8664), underscoring its applicability for construction noise control. These results offer valuable insights into sound propagation dynamics and provide a basis for developing effective noise control strategies.

Published: June 2024

We undertook a search for new nearby dwarf galaxies outside the known groups in the Local Volume using the data on DESI Legacy Imaging Surveys. In a wide sky area of ~5000 square degrees directed toward the Local Void, we found only 12 candidates to nearby low mass galaxies. Almost all of them are classified as irregular or transition type dwarfs. Additionally, we examined areas of the sky exposed with the Hyper Suprime Camera of the Subaru telescope (~700 square degrees) and found nine more candidates to nearby dwarfs. Finally, nine candidates to the Local Volume were selected by us from the Zaritsky's SMUDG catalog that contains 7070 ultra-diffuse objects automatically detected in the whole area of the DESI surveys. We estimated a fraction of quiescent dSph galaxies in the general cosmic field to be less than 10 percent.
Используя данные обзора DESI Legacy Imaging Surveys, мы предприняли поиск новых близких карликовых галактик вне известных групп в Местном Объеме. В обширной области неба площадью примерно 5000 квадратных градусов, направленной к Местному Войду, мы нашли только 12 кандидатов в близкие галактики низкой массы. Все они классифицированы как иррегу лярные либо карлики переходного типа. Дополнительно мы обследовали площади неба, снятые телескопом Субару с камерой Hyper Suprime Camera (около 700 кв. град.) и обнаружили еще девять кандидатов в близкие карлики. Наконец, 9 кандидатов в Местный Объем были отобраны нами из каталога Зарицкого (SMUDG), который содержит 7070 ультра-диффузных объектов, найденных автоматически на всей площади обзора DESI.

Published: June 2024

Проведено моделирование магнитного поля звезды HD133880 при предположении структуры магнитного поля описываемого двумя теоретическими магнитными диполями. Сравнение результата с тем, что получалось ранее при использовании представления фазовой зависимости Be(Ф) путем дипольно + квадрупольно + октупольного расширения структуры показывает, что эта схема приводит только к формальному описанию фазовой зависимости, а члены разложения не несут физического смысла.
The magnetic field of the star HD133880 is modeled under the assumption of the structure of the magnetic field in the form of a theoretical magnetic dipole. Comparison of the result with what was obtained earlier when using the representation of the phase dependence of Be(Ф) by dipole+quadrupole +octupole expansion of the structures shows that this scheme leads only to a formal description of the phase dependence, and the expansion coefficients do not have physical meaning.

We have carried out a spectral classification by the activity types for a subsample of blazars from the BZCAT v.5 Catalogue, namely the Flat Spectrum Radio Quasars (FSRQ) candidates, designated in the catalogue as BZQ subtype objects. The classification is based on the Sloan Digital Sky Survey (SDSS) homogeneous medium-resolution optical spectroscopy and along with the standard BPT-type diagnostic diagrams, we have applied our newly introduced fine classification scheme with subtypes of quasars and considering many more features. Out of 1909 BZQ objects, 618 having SDSS spectra were classified, resulting in 445 broad-line QSOs, 19 narrow-line QSOs, 138 broad-line Seyferts, 8 narrow-line Seyferts, and 2 Emission-line galaxies without a proper classification. We have calculated the absolute magnitudes and luminosities for all objects to distinguish QSOs from Seyferts, as defined by the Catalogue of QSOs and Active Galaxies, -22m.25 separation limit. This way 148 objects changed their BZCAT subtypes between BZQ to BZG, and also 6 BZQ objects to BZU.
Проведена спектральная классификация кандидатов в радиоквазары с плоским спектром (FSRQ) из каталога BZCAT v.5, обозначенные в каталоге как объекты подтипа BZQ. Классификация основана на оптической спектроскопии среднего разрешения Слоановского цифрового обзора неба (SDSS), и наряду со стандартными диагностическими диаграммами BPT- типа применена недавно введенная авторами схема тонкой классификации с подтипами квазаров и учетом многих других особенностей. Из 1909 BZQ объектов классифицированы 618, которые имеют спектры SDSS, в результате чего имеем: 445 квазаров с широкими линиями, 19 квазаров с узкими линиями, 138 Сейфертов с широкими линиями, 8 Сейфертов с узкими линиями и 2 эмиссионные галактики. Рассчитаны абсолютные звездные величины и светимости для всех объектов, чтобы отличить QSO от сейфертовских галатик, как это определено каталогом квазаров и активных галактик c пределом разделения -22m.25. В результате, 148 объектов изменили свой BZCAT подтип между BZQ и BZG, а 6 объектов с BZQ на BZU.

Authors: Hoang Lisa
Published: June 2024

Higher educational settings have a slow rise of women in engineering programs. This literature review synthesizes existing research and has intentions to gain further understanding of female undergraduate engineering students—such as perceptions and experiences—on their respective university campus and internship programs through answering the below the main research: What is the nature of the experience of female undergraduate engineering students on university campus and in internship programs? This literature review provides important insights of needing support programs at early stages for students in their undergraduate education. Early interventions such as informal mentor relationships provide female students with stronger engineering identities for female engineering students. Ten research articles are examined in this literature review. The selection criteria emphasize on primary, peer reviewed articles that had to be in English with recent publications (earliest publication date of 2007) in the engineering or STEM field, the article revolved in higher education settings with students, faculty or staff as participants, article research objectives involve with gendered issues or mentorship programs and lastly, the articles involve with internship or academic support. Although the literature across were all in English, this literature review contains research from other countries—though mainly are from United States—Australia, England, Brazil, Spain and Kazakhstan. The variety of countries included provided consistencies that contextual support and supportive programs are crucial for fostering greater self-efficacy, persistency and resiliency for female undergraduate engineering students.

Published: June 2024

Recent economic trend has recorded increasing adoption of digital technology in the world of finance, yet the challenge of financial literacy and poor access to digital financial services by women entrepreneurs in Nigeria continues to plague the entrepreneurial endeavors of women, triggering a great concern to policy makers. Access to digital finance represents not just a formidable opportunity but a crucial imperative in empowering women entrepreneurs, therefore this research investigated the transformative potential of digital financial services in improving the performance and empowerment of women entrepreneurs in Abuja municipal area council (AMAC). The paper employed a descriptive research design based on primary data, using survey questionnaires, targeted at three hundred and eighty-four (384) respondents, and administered to both registered and unregistered women entrepreneurs. Responses to questionnaires were collated and analyzed using the ordinal logistic regression method to reveal a significant and beneficial correlation between the variables. The paper confirmed that access to digital financial services (DFS) has a positive impact on the performance and empowerment of female entrepreneurs as it provided crucial financial tools, improved decision making and encouraged financial independence. Based on the findings, the paper therefore recommended the implementation of specialized financial solutions offering credit and savings products, robust digital infrastructure development by the government, and advocacy for gender-responsive policies to further drive practical changes for women entrepreneurs. The paper concluded by advocating a joint action to promote women’s empowerment and economic growth by leveraging the transformative power of digital financial services.
Resistance Mechanisms and Treatment Burdens for A. baumannii infections: Current Challenges and Future Opportunities
Authors: Eissa Mostafa
Published: June 2024

Acinetobacter baumannii is a Gram-negative bacterium that can cause serious infections in humans, especially in health care settings. It is known for its ability to acquire resistance to multiple antibiotics, limiting the treatment options and increasing the mortality rates. The aim of this paper is to review the current knowledge on the resistance, the treatment strategies, and the future perspectives of A. baumannii infections. There should be some background understanding on the taxonomy, ecology, epidemiology, and clinical significance of A. baumannii. The review of previous studies summarizes the main findings from the literature review, covering the different mechanisms of resistance, such as beta-lactamases, efflux pumps, target mutations, and porin loss, and how they affect the susceptibility and efficacy of various classes of antibiotics, such as penicillins, cephalosporins, carbapenems, fluoroquinolones, aminoglycosides, sulfonamides, and colistin. The previous screening research studies highlight the limitations and challenges of the current treatment options, such as toxicity, resistance development, poor penetration, and narrow spectrum, and identifies the gaps and needs for the future research and development of new therapies and modalities, such as new antibiotics, alternative therapies, vaccines, immunotherapy, and nanotechnology. The final analysis concludes that A. baumannii is a highly resistant bacterium that poses a serious challenge for the clinical management of infections, and that more research and innovation are needed to discover new antibiotics and alternative modalities that can target A. baumannii and overcome its resistance mechanisms. One of the promising tools is the use of the Artificial Intelligence (AI) in the discovery of new promising drugs.

Background: Enterococcu has continued to attract considerable importance and attention as pathogens of public health concern in both environmental and hospital settings, which has made epidemiological studies of the organisms a major interest in research. Enterococci are opportunistic pathogens that cause a variety of infections in men. The aim of the study was to isolate and determine the antibiotic susceptibility pattern of Enterococcu species in fast food outlets within the Lagos metropolis.
Methods: Enterococci were isolated from food samples and culture was performed by emulsifying the bacterial colonies on agar plates followed by incubation for 24 hours at 32ᵒC. Enterococci were identified by the morphological appearance on selective media, and biochemical tests such as catalase, oxidase, indole, urease activity, hydrogen sulphide production, nitrate reduction, citrate utilization, and so on, were performed. Antibiotic susceptibility of the Enterococcu isolates was determined using the disc diffusion method. Sixty samples from different areas within the Ojo metropolis of Lagos State were examined for the presence of Enterococci.
Results: Out of the samples, 28 (47.6%) were positive for Enterococci. Of all 28 strains of Enterococci isolated, Enterococcu faecalis was the most predominant (67.9%) which was isolated from palms of food handlers, followed by Enterococcu gallinarium (21.4%) which was isolated from food while Enterococcu faecium (10.7%) was isolated from table tops. This study revealed the prevalence of E. faecalis, E. gallinarium, and E. faecium in the fast-food outlets in Ojo, Lagos State, Nigeria. Antibiotic susceptibility analysis showed that the isolates were susceptible to Amoxicillin (100%), and were highly susceptible to Augmentin (92.9%), Erythromycin (92.9%), and Chloramphenicol (92.9%), showed moderate susceptibility to Gentamycin (85.7%), Cotrimoxazole (89.3%), and Cloxacillin (82.1%) but developed highest resistance to Tetracycline (64.3%). This is an indication that Amoxicillin is the most efficacious antibiotic.
Conclusion: The study has revealed that food samples from a number of food outlets in Ojo, Lagos State, Nigeria, were contaminated with Enterococci, suggesting a possible reservoir of the organism. There is a need for periodic and instant epidemiological evaluation and enforcement of very good hygienic practices especially in the area that has been studied. A high preponderance of Enterococci as contaminants of ready-to-eat food was recorded, which also showed a high level of multiple drug resistance, thus, constituting a threat to public health.

Worldwide breast cancer is most frequently diagnosed and leading cause of cancer related deaths in women. Hormone therapy, Tamoxifen is recommended in ER+ve patients.10 years of tamoxifen treatment can approximately halve breast cancer mortality during the second decade after diagnosis.A 32-year-old woman was having a large palpable lump in the lower inner quadrant of breast measuring 6*5cm for last 4months, for which a biopsy was taken, and it was invasive ductal carcinoma, grade II. She presented to INMOL in September 2010 after upfront MRM surgery.The patient had no co-morbidities and 4 cycles of FAC followed by 4 cycles of paclitaxel were given and chemotherapy was completed on Feb,2011.Patient was treated on Co-60, giving a dose of 40Gy/15 Fractions with 2 tangential fields ,one anterior supraclavicular fossa field plus posterior axillary boost . The patient was given 20 mg of tamoxifen daily and put on follow-up. Patient remained well while on tamoxifen. Tamoxifen stopped after 10 years. After 3 years of stopping tamoxifen she was presented in June 2023 she developed bone and pulmonary mets.After stabilization, palliative radiotherapy was given with dose 12Gy/2 fractions. After one month, patient’s symptoms were much better so tamoxifen treatment continued.in our case ER,PR +ve ,her2 negative node positive disease, disease recurred with distant bony and pulmonary metastasis after discontinuing tamoxifen suggests that in premenopausal younger patients with heavy burden disease like positive axillary nodes, tamoxifen should be continued even after 10 years.
