Effect of preprocedure anxiety and oestrogen levels on Postoperative Nausea and Vomiting in patients undergoing diagnostic laparoscopy and hysteroscopy for infertility: A prospective observational pilot study.

BACKGROUND: Females undergoing laparoscopic gynaecological surgeries have a high incidence of postoperative nausea and vomiting. Apart from the established risk factors, hormonal, psychological, genetic and ethnic factors may also contribute to postoperative nausea and vomiting. This study aimed to evaluate the relationship between preoperative anxiety and serum oestrogen level with postoperative nausea and vomiting in patients undergoing diagnostic laparoscopy - hysteroscopy for infertility. METHODS: In total, 100 female patients, between the ages of 20-40 years, undergoing diagnostic laparoscopy - hysteroscopy for infertility were recruited for this study. Preoperative anxiety level was assessed using Depression, Anxiety and Stress Scale-21 (DASS-21) Questionnaire. Serum oestrogen samples were taken before anaesthesia. Postoperative nausea and vomiting grading was rated with 0-3 Likert-type scale. An association of anxiety and oestrogen levels to postoperative nausea and vomiting was done. RESULTS: The analysis between median DASS 21 scores to postoperative nausea and vomiting grading showed no association between DASS 21 scores and postoperative nausea and vomiting grades. Comparing the mean oestrogen levels in patients among each grade of postoperative nausea and vomiting showed no significant difference in the mean oestrogen levels. CONCLUSION: Our study did not find evidence of a significant association between serum oestrogen levels, preoperative anxiety, and postoperative nausea and vomiting.

Machine learning analysis of thermophysical and thermohydraulic properties in ethylene glycol- and glycerol-based SiO2 nanofluids.

The study investigates the heat transfer and friction factor properties of ethylene glycol and glycerol-based silicon dioxide nanofluids flowing in a circular tube under continuous heat flux circumstances. This study tackles the important requirement for effective thermal management in areas such as electronics cooling, the automobile industry, and renewable energy systems. Previous research has encountered difficulties in enhancing thermal performance while handling the increased friction factor associated with nanofluids. This study conducted experiments in the Reynolds number range of 1300 to 21,000 with particle volume concentrations of up to 1.0%. Nanofluids exhibited superior heat transfer coefficients and friction factor values than the base liquid values. The highest enhancement in heat transfer was 5.4% and 8.3% for glycerol and ethylene glycol -based silicon dioxide Nanofluid with a relative friction factor penalty of ∼30% and 75%, respectively. To model and predict the complicated, nonlinear experimental data, five machine learning approaches were used: linear regression, random forest, extreme gradient boosting, adaptive boosting, and decision tree. Among them, the decision tree-based model performed well with few errors, while the random forest and extreme gradient boosting models were also highly accurate. The findings indicate that these advanced machine learning models can accurately anticipate the thermal performance of nanofluids, providing a dependable tool for improving their use in a variety of thermal systems. This study's findings help to design more effective cooling solutions and improve the sustainability of energy systems.

Evaluation of microplastic pollution and risk assessment in a tropical monsoonal estuary, with special emphasis on contamination in jellyfish.

Estuaries, which serve as vital links between land and coastal ecosystems, play a significant part in facilitating the transfer of plastic waste from the land to the ocean. In this research, we examined the prevalence, characteristics, and ecological risks of microplastics (MPs) in the extensively urbanized Cochin Estuarine System (CES), India. Additionally, it represents one of the initial evidence-based examinations of MPs ingestion by jellyfish in Indian waters, focusing on Acromitus flagellatus, Blackfordia virginica, and Pleurobrachia pileus species. The abundance of MPs found in the surface water of the Cochin Estuarine System (CES) varied between 14.44 ± 9 to 30 ± 15.94 MP/m3, with an average of 21.6 ± 11 MP/m3. In both surface waters and jellyfish from the Cochin Estuarine System (CES), fibers were the most prevalent type of MPs, with polyethylene (PE), polypropylene (PP), and polyamide (PA) being the most common polymer varieties. To evaluate the current levels of MPs and their effect on the CES, the Pollution Load Index (PLI), Potential Ecological Risk Index (PERI), and Polymeric Risk Index (H) were utilized. The high PLIestuary values (20.33), high Hestuary values (234.02), and extreme PERIestuary value (1646.06) indicate that the CES is facing an extreme ecological risk. Among the 280 jellyfish individuals examined, 118 (42.14%) were recognized to contain MPs with an average of 1.54 ± 2.68 MPs/individual. Pearson bivariate analysis revealed a significant correlation between the jellyfish bell size and number of plastics per individual. Comparison between jellyfish species revealed, the majority (66%) of the MPs identified in jellyfish were from A. flagellatus and 44 among the 50 jellyfish examined (88%) had MPs. These findings suggest that A. flagellatus may be a potential sink for MPs and may be utilized to be a bioindicator for monitoring MPs contamination in estuarine systems, aiding in future plastic pollution mitigation efforts.

THE MICROBIOME AND METABOLIC DISORDERS: THE LINK BETWEEN THE GUT MICROBIOTA AND METABOLIC SYNDROME.

The diverse population of microbes that live in our digestive system, known as the gut microbiota, remains essential for many physiological processes. It plays a role in obtaining energy from food and controls both regional and overall immunity. In addition, changes in the microbiota of the digestive tract are connected to the emergence of an extensive variety of illnesses, such as cancer, gastrointestinal problems, and metabolic disorders. From a metabolic perspective, the gut microbiota can affect processes like lipid accumulation, lipopolysaccharide satisfied, and short-chain fatty acid synthesis, all of which have an effect on food intake, inflammatory reactions, and insulin signaling. Prebiotics, probiotics, specialized anti-diabetic medications, and faecalmicrobiota implantation are a few of the ways that have been discovered to alter the gut microbiota; each has a different influence the human body's metabolism and the emergence of metabolic disorders. These therapies have been reported to be therapeutic strategies for enhancing general wellness and reestablishing a balanced gut flora.

Cardio-oncology in China.

OPINION STATEMENT: Cardio-oncology is going under rapid development in various areas across an increasing number of provinces in China. However there are still a myriad of challenges that need to be overcome in order to ensure its gradual and consistent expansion. The Cardio-Oncology Knowledge Transfer Model (KTM) forms the basis to allow exponential development of effective cardio-oncology services. This would ensure the implementation of precision-based practice while dynamically evolving cardio-oncology to integrate both Western and Chinese medical practices to become an official clinical sub-speciality in its own right in China, for the ultimate benefit of the patient.

Deoxyglucose-conjugated persistent luminescent nanoparticles for theragnostic application in fibrosarcoma tumor model.

Deoxyglucose conjugated nanoparticles with persistent luminescence have shown theragnostic potential. In this study, deoxyglucose-conjugated nano-particles with persistent luminescence properties were synthesized, and their theragnostic potential was evaluated in fibrosarcoma cancer cells and a tumor model. The uptake of nano-formulation was found to be higher in mouse fibrosarcoma (WEHI-164) cells cultured in a medium without glucose. Nanoparticles showed a higher killing ability for cancer cells compared to normal cells. A significant accumulation of nanoparticles to the tumor site in mice was evident by the increased tumor/normal leg ratio, resulting in a significant decrease in tumor volume and weight. Histopathological studies showed a significant decrease in the number of dividing mitotic cells but a greater number of apoptotic/necrotic cells in nanoparticle-treated tumor tissues, which was correlated with a lower magnitude of Ki-67 expression (a proliferation marker). Consequently, our results showed the potential of our nano-formulation for cancer theragnosis.

Role of Intravenous Iron Sucrose in Severe Anemia in Late Pregnancy: A Case Report From Rural Ballabgarh, Haryana.

Severe anemia is a high-risk factor in pregnancy and needs to be treated appropriately to prevent poor maternal and fetal outcomes. A pregnant woman with severe anemia reluctant for blood transfusion due to issues of accessibility was given four doses of 300 mg intravenous iron sucrose (IVIS) in 300 ml normal saline starting at 31 weeks 5 days of gestation and her hemoglobin level increased by 4.2 gm/dl over a period of five weeks without any complications and without any intake of iron and folic acid tablets during the entire duration. Intravenous iron sucrose is a useful intervention for severe anemia of pregnancy even in late pregnancy with rapid increase in haemoglobin levels and can be used regularly for treating severe anemia in pregnant women alternative to blood transfusion who have limited accessibility to blood transfusion facilities.

Decreasing the Rate of Surgical Site Infection in Patients Operated by Cesarean Section in a Tertiary Care Hospital in India: A Quality Improvement Initiative.

Background Surgical site infections (SSIs) are a substantial cause of maternal morbidity and are associated with a significant increase in hospital stay and cost. The prevention of SSI is complex and requires the integration of a range of measures before, during, and after surgery. Jawaharlal Nehru Medical College (JNMC), Aligarh Muslim University (AMU) is one of the referral centers of India with a huge influx of patients. Methods The project was undertaken by the Department of Obstetrics and Gynaecology, JNMC, AMU, Aligarh. Our department was sensitized to the need for quality improvement (QI) through Laqshya, a Government of India initiative for labor rooms in 2018. We were facing problems like a high surgical site infection rate, poor documentation and records, no standard protocols, overcrowding, and no admission discharge policy. There was a high rate of surgical site infections, leading to maternal morbidity, increased days of hospitalization, more usage of antibiotics, and increased financial burden. A multidisciplinary quality improvement (QI) team was formed comprising obstetricians and gynecologists, the hospital infection control team, the head of the neonatology unit, staff nurses, and multitasking staff (MTS) workers. Results The baseline data were collected for a period of one month and it was found that the rate of SSI was around 30%. Our aim was to decrease the rate of SSI from 30% to less than 5% over a period of six months. The QI team worked meticulously, implemented evidence-based measures, regularly analyzed the results, and devised measures to overcome the obstacles. The point-of-care improvement (POCQI) model was adopted for the project. The rate of SSI decreased significantly in our patients and the rates are around 5% persistently. Conclusion The project not only helped in decreasing the infection rates but also led to vast improvements in the department with the formulation of an antibiotic policy, surgical safety checklist, and admission-discharge policy.

Association of Waist Circumference and Body Mass Index among the Students of a Medical College.

Background Obesity and overweight have emerged as significant public health concerns on a global scale. In the pursuit of evaluating body composition and identifying potential health risks, two widely utilized measures are Body Mass Index and waist circumference. These anthropometric indicators are considered economical, practical, and also crucial for screening, monitoring the individual's nutritional status, and anticipating future disease risk. Objective To explore the correlation between waist circumference and Body Mass Index and find out its significance as indicators of health and nutritional status in young adults. Method The study comprises 260 healthy young adults, aged 18-25 years from pre-clinical sciences, Kathmandu University School of Medical Sciences (KUSMS). Anthropometric measurements of height (m), weight (kg), and waist circumference (cm) were recorded. Body Mass Index was calculated by using the formula as body weight (kg) divided by the square of body height (m2). Demographic factors such as age, sex, obesity, and life style factors like smoking, alcohol consumption, and physical activity were noted. Result The study found a positive correlation between Body Mass Index, waist circumference (WC) and weight. However, no association was found between waist circumference and height. The findings also indicated a notably high percentage of 17.69% participants, who were categorized as overweight, while a 9.23% fell into the underweight category. The study confirms that 83.08% of the students have moderate physical activity whereas 14.62% have insufficient and 2.31% have heavy physical activity. Conclusion The study shows a positive correlation between body mass index (BMI) and waist circumference (WC) in young adults aged 18-25 years.

Successful Treatment of Bronchopulmonary Sequestration by Radiofrequency Ablation of Feeding Artery.

INTRODUCTION: Most cases of bronchopulmonary sequestration (BPS) regress. Prenatal intervention is needed in cases of fetal hydrothorax or hydrops. Laser is commonly used to ablate the feeding artery. CASE PRESENTATION: In a fetus with BPS, radiofrequency ablation (RFA) was used to ablate the feeding artery arising from descending aorta at 29 weeks gestation. There was an extralobar BPS and significant pleural effusion causing mediastinal shift and collapse of lung. The effusion and tumor started decreasing from day 3 after procedure, and by the time patient delivered at 36 weeks gestation, the lesion had almost resolved. CONCLUSION: With proper technique, RFA can be safely used to ablate feeding artery in BPS.

Methotrexate pneumonitis in a patient with gestational trophoblastic neoplasia.

Methotrexate, an immunomodulatory agent used for a wide variety of indications, can cause pulmonary toxicity in the form of pneumonitis, organising pneumonia, pulmonary fibrosis, pleural effusion, pulmonary infections or lymphoproliferative disease. We report a case of methotrexate pneumonitis in a patient with gestational trophoblastic neoplasia. The diagnosis of methotrexate pneumonitis is challenging, as the signs and symptoms can be caused by intercurrent infection, concomitant medications or an underlying disease condition. A high index of suspicion is required for diagnosis. Management consists of drug discontinuation and steroids in patients with respiratory failure.

Diabetes in Pregnancy Study Group India (DIPSI) and WHO (1999) diagnostic criteria for GDM: A meta-analysis.

BACKGROUND AND AIMS: The diagnosis of Gestational diabetes mellitus (GDM) is challenging and controversial due to the heterogeneity or lack of consensus regarding the screening and diagnostic criteria for GDM. METHODS: A meta-analysis of studies comparing Diabetes in Pregnancy Study Group India (DIPSI) and WHO 1999 for diagnosing GDM was carried out. RESULTS: A total of 6 comparative studies were included. Pooled analysis showed sensitivity and specificity as 0.79 (95% CI: 0.53 to 0.92) and 0.97 (95% CI: 0.94 to 0.98) respectively. CONCLUSION: Based on the results of the meta-analysis, DIPSI showed higher specificity when compared to WHO 1999, hence may be used to rule in disease in probable GDM cases. However, the results should be interpreted more cautiously and carefully since only a few studies were included.

Nutritional Profiling and Antioxidant Property of Three Wild Edible Mushrooms from North East India.

The mushroom is an important food for the rural tribal populations in Manipur, because of its high nutritional contents. In this study, we report on the nutritional profile of three wild edible mushrooms consumed by the tribal populations of Manipur viz.: Macrocybe gigantea J124; Lactifluus leptomerus J201 and Ramaria thindii J470. The studied mushrooms possess a high protein content of 37.6%, 20.8% and 16.4%, respectively. They have a high vitamin C content with low vitamin B1, B2 and folic acid. Among the three mushrooms, M. gigantea J124 possesses the highest mineral content, followed by R. thindii J470 and L. leptomerus J201. The total phenolic content of L. leptomerus J201, M. gigantea J124 and R. thindii J470 were 26.206, 29.23 and 30.99 mg GAE/g, with flavonoid content of 6.646, 6.854 and 9.187 mg quercetin/g, respectively. R. thindii J470 has the highest TPC and TFC content, which correlates with its DPPH radical scavenging activity. The IC50 values for R. thindii J470, M. gigantea J124 and L. leptomerus J201 are 242.0 µg/mL, 550.4 µg/mL and 689.0 µg/mL, respectively, which suggest that the higher content of phenolic compounds in R. thindii J470 contributes to its radical scavenging properties.

Cardiac Safety in Breast Cancer Patients Receiving Pegylated Liposome Doxorubicin Sequential Anti-HER2 Monoclonal Antibody Therapy.

Background: Cardiotoxicity associated with the sequential use of anthracyclines followed by trastuzumab is common in adjuvant therapy of patients with HER2-positive early breast cancer (eBC). However, the cardiac safety of trastuzumab concurrent with pegylated liposomal doxorubicin (PLD) is relatively less studied. Method: Clinical data of patients with HER2-positive eBC treated with PLD and cyclophosphamide (PLD-C) followed by taxanes plus trastuzumab ± pertuzumab (TH or TPH) who then completed standard anti-HER2 treatment for 12 months from June 2012 to August 2021 were retrospectively collected. The primary endpoints were clinical and subclinical cardiotoxicity. Result: In total, 70 eligible patients were enrolled. Among them, 55 patients (78.6%) received PLD-C → TH and 15 patients (21.4%) received PLD-C → TPH. The median follow-up time was 41.8 months. Until August 2021, only two patients had recurrent or metastatic diseases, with 2-year and 5-year disease-free survivals of 98.6% and 96.8%, respectively. Clinical cardiotoxicity occurred in six patients (8.6%), and all of them had an absolute decline of ≥16% from baseline left ventricular ejection fraction (LVEF) but not below the lower limit of normal (LLN = 50%). Subclinical cardiotoxicity events occurred in 17 patients (24.3%), and all of them had absolute declines of ≥10% and <16% from baseline LVEF but not below the LLN. No patients were interrupted from treatment, and all patients completed anti-HER2 treatment for 12 months. The sharpest decrease in LVEF was observed at 18 months after the start of PLD treatment. The cumulative incidences of clinical and subclinical cardiotoxicity were 9.8% and 28.3%, respectively. In the univariate analysis, body mass index, age, left chest wall radiotherapy, and ongoing cardiovascular risk factors were not significantly associated with clinical or subclinical cardiotoxicity (p > 0.05). No patients had congestive heart failure or death caused by PLD or anti-HER2 treatment. Conclusion: The sequential use of PLD and trastuzumab showed a lower incidence of clinical cardiotoxicity, presented as asymptomatic decreased LVEF, compared with the results obtained in previous clinical studies using conventional anthracycline, taxanes and trastuzumab. The study regimen demonstrated good cardiac tolerance and is an alternative strategy for cardioprotection in patients with HER2-positive eBC.

Multimodal Applications of Zinc Gallate-Based Persistent Luminescent Nanoparticles in Cancer Treatment: Tumor Margining, Diagnosis, and Boron Neutron Capture Therapy.

On the basis of the boron neutron capture therapy (BNCT) modality, we have designed and synthesized a zinc gallate (ZnGa2O4)-based nanoformulation for developing an innovative theranostic approach for cancer treatment. Initially, the (ZnGa1.995Cr0.005O4 or ZnGa2O4:(0.5%)Cr persistent luminescence nanoparticles (PLNPs) embedded on silica matrix were synthesized. Their surface functionalization was performed using organic synthesis strategies to attach the amine functional moieties which were further coupled with poly(vicinal diol). These diols were helpful for conjugation with 10B(OH)3, which subsequently served to couple with an in-house-synthesized variant of pH-(low)-insertion peptide (pHLIP) finally giving a tumor-targeting nanoformulation. Most importantly, the polymeric diols helped in conjugation of a substantial number of 10B to provide the therapeutic dose required for effective BNCT. This nanoformulation internalized substantially (∼80%) to WEHI-164 cancer cells within 6 h. Tumor homing studies indicated that the accumulation of this formulation at the acidic tumor site was within 2 h. The in vitro evaluation of the formulation against WEHI-164 cancer cells followed by neutron irradiation revealed its potent cytotoxicity with IC50 ∼ 25 µM. In the case of studies on animal models, the melanoma-induced C57BL/6 and fibrosarcoma-induced BALB/c mice were treated with formulations through intratumoral and intravenous injections, respectively, followed by neutron irradiation, leading to a significant killing of the cancer cells, which was evidenced by a reduction in tumor volume (75-80%) as compared with a control tumor. Furthermore, the histopathological studies confirmed a damaging effect only on tumor cells, while there was no sign of damage to the vital organs in treated mice as well as in controls.

Pattern of Male Hypogonadism and Outcome of Treatment in South Rajasthan.

Male reproductive functions are governed by hypothalamic pituitary testicular axis. If any component of this axis malfunctions, then hypogonadism will develop which is characterized by ill-defined secondary sexual features and low serum testosterone. The common patterns seen are primary and secondary testicular failure in the young; and late onset hypogonadism in the elderly. All such cases can be virilized and managed by androgen supplementation. Spermatogenesis can be induced by use of appropriate gonadotropins in selected cases. The aim of the study was to find out the pattern, management and outcome of male hypogonadism. MATERIAL: It was a prospective questionnaire based observational study, carried out on infertile hypogonadic males, attending medicine outdoor at medical college hospital from January 2015 to December 2020. There were 50 males with hypogonadic features, cases of late onset of hypogonadism were excluded. Sexual maturity rating, semen analysis, serum testosterone and FSH level were estimated in all patients at baseline and at 6 months duration of treatment. Testicular biopsy, Karyotyping and MRI brain were performed in selected cases. Azoospermic patients having hypogonadotropic hypogonadism were treated with long-acting testosterones and gonadotropins. OBSERVATION: The study subjects were infertile azoospermic males. On the basis of serum FSH and testosterone levels, they were classified into two groups. Group A (n=42) cases were hypergonadotropic hypogonadism or primary testicular failure; of these 32 were Klinefelter syndrome (XXY), 7 chronic orchitis and 3 empty scrotal syndrome including one case of anorchia. These patients also developed other systemic illnesses in addition to hypogonadism. Group B (n=8) hypogonadotropic hypogonadism or secondary testicular failure; of these 2 were Kallman syndrome and the rest were idiopathic. After testosterone replacement all patients were virilized and there was marked improvement in libido and androgenization. CONCLUSION: The study brings out that primary testicular failure is more common than secondary testicular failure. Both pattern of hypogonadism should receive lifelong androgen replacement therapy; otherwise, they will be a basket of multiple systemic disorders. Presently testosterone undecanoate once in every three months is the agent of choice.

Mesoporous Silica-Coated Upconversion Nanoparticles Assisted Photodynamic Therapy Using 5-Aminolevulinic Acid: Mechanistic and In Vivo Studies.

Exclusively red-emitting upconversion nanoparticles (UCNPs) with the composition NaErF4:0.5%Tm as a core and NaYF4 as a shell were synthesized for performing photodynamic therapy (PDT). A possible mechanism was proposed for core-shell UCNPs formation. For loading a maximum amount of 5-aminolevulinic acid (5-ALA), mesoporous silica coating was performed on UCNPs. Studies under dark conditions confirmed the biocompatibility of 5-ALA-loaded UCNPs formulation (UCNPs-5-ALA) with MCF-7 cells. Meanwhile, studies under light-exposed conditions exhibited effective cytotoxicity against MCF-7 cells. Studies employing D2O-based cell cultured media and addition of DABCO in cell culture established that the cell death was due to oxidation of cellular components by reactive oxygen species (ROS) triggering the apoptosis. The formation of ROS was confirmed by DCF(H)DA-based ROS analysis via fluorescence microscopy to demonstrate the ROS production, which mediates the programmed cell death. Additionally, we have validated the apoptosis in MCF-7 cells with flow cytometry analyses. This was further confirmed by an electrophoretic mobility shift assay on nuclear extract and measurement of mitochondrial membrane potential. In the case of animal model studies, the formulation UCNPs-5-ALA without irradiation (980 nm) did not possess any in vivo cytotoxicity on tumor-induced SCID mice and there was a minimum migration of UCNPs-5-ALA to the vital organs but maximum retention at the tumor site only. Meanwhile, only the mice treated with UCNPs-5-ALA and irradiated on the tumor region with 980 nm laser (500 mW) for 20 min possessed a tumor with a size reduced to about 75% as compared with the corresponding control groups. To the best of our knowledge, this type of study was conducted for the first time employing exclusively red-emitting phosphors for effective PDT.

Facile Synthesis of a Pt(IV) Prodrug of Cisplatin and Its Intrinsically 195mPt Labeled Analog: A Step Closer to Cancer Theranostic.

BACKGROUND AIMS AND OBJECTIVES: Cisplatin is extensively used in chemotherapy for treatment of a broad range of cancers. But its undesired side reactions with biomolecules that lead to severe side effects especially on kidney and nervous system, are limiting its clinical utility. To reduce its side effects, the kinetically inert Pt(IV) prodrug was recognized as an alternative approach from satisfactory results of preliminary experiments. But, its approval as anticancer drug for clinical use requires detailed investigations of its anticancer action and pharmacological pathways by employing its analogue which can be traced by a suitable technique. As a step closer towards translation of Pt(IV)-based prodrug from research to clinical level, a protocol for efficient synthesis of 195mPt-radiolabeled Pt(IV) prodrug was devised. MATERIALS AND METHODS: In order to achieve the aim, we started synthesis from elemental platinum avoiding lengthy steps. The synthesis protocol was standardized on its cold analogue, as [PtCl2(NH3)2(OCOCH2CH2COOH)2] which has been characterized with nuclear magnetic resonance (1H, 13C{1H} and 195Pt{1H}) spectroscopy, microanalyses and cyclic voltammetry. Also, cytotoxicity of [PtCl2(OCOCH2CH2COOH)2(NH3)2] was evaluated against MCF-7 human breast cancer cell lines using cisplatin as test control. RESULTS: Intrinsically, 195mPt-labeled analogue of prodrug was obtained with high radionuclidic and radiochemical purity. It was confirmed by chromatography and γ-ray spectrometry. CONCLUSION: The 195mPt-radiolabeled prodrug was synthesized in a facile manner. It can be utilized in evaluating the mechanism of anticancer action and pharmacokinetics by enabling synergistic use of molecular imaging and targeted drug delivery.

COVID-19 impact on screening test volume through the National Breast and Cervical Cancer early detection program, January-June 2020, in the United States.

Women from racial and ethnic minority groups face a disproportionate burden of cervical and breast cancers in the United States. The Coronavirus Disease 2019 (COVID-19) pandemic might exacerbate these disparities as supply and demand for screening services are reduced. The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides cancer screening services to women with low income and inadequate health insurance. We examined COVID-19's impact on NBCCEDP screening services during January-June 2020. We found the total number of NBCCEDP-funded breast and cervical cancer screening tests declined by 87% and 84%, respectively, during April 2020 compared with the previous 5-year averages for that month. The extent of declines varied by geography, race/ethnicity, and rurality. In April 2020, screening test volume declined most severely in Health and Human Services Region 2 - New York (96% for breast, 95% for cervical cancer screening) compared to the previous 5-year averages. The greatest declines were among American Indian/Alaskan Native women for breast cancer screening (98%) and Asian Pacific Islander women for cervical cancer screening (92%). Test volume began to recover in May and, by June 2020, NBCCEDP breast and cervical cancer screening test volume was 39% and 40% below the 5-year average for that month, respectively. However, breast cancer screening remained over 50% below the 5-year average among women in rural areas. NBCCEDP programs reported assisting health care providers resume screening.
