“…Despite being the most common cancer, the 5-year relative survival rate of breast carcinoma remains more than 80% when the disease is detected early [3]. To improve the survival, a number of screening methods to detect breast cancer have been studied, including magnetic resonance imaging (MRI), Doppler ultrasonog-raphy (US) and computed tomography (CT) [4]. The most practical screening method in clinical diagnosis and treatment is US.…”

Aim: This meta-analysis aimed to identify the accuracy of ultrasound superb microvascular imaging (SMI) for the diagnosis of a breast tumor.Material and method: We searched PubMed, Web of Science, Google Scholar, Cochrane Library, EBSCO, and CBM databases from January 1st, 2013 until February 1st, 2020 without language restrictions. Meta-analysis was conducted using STATA version 14.0 and Meta-Disc version 1.4 software. We calculated the summary statistics for sensitivity (Sen), specificity (Spe), positive and negative likelihood ratio (LR+/LR−), diagnostic odds ratio (DOR) and receiver operating characteristic (SROC) curve.Results: Fifteen studies that met all inclusion criteria were included in this meta-analysis. A total of 955 breast neoplasm patients and 1116 patients with benign breast tumors were assessed. All breast lesions were histologically confirmed after SMI. The pooled Sen was 0.81 (95%CI=0.78-0.83); the pooled Spe was 0.71 (95%CI=0.68-0.73) The pooled LR+ was 3.24 (95%CI=2.27-4.64); the pooled negative LR−was 0.25 (95%CI=0.18-0.34) The pooled DOR of SMI in the diagnosis of breast tumor was 46.97 (95 % CI=16.72∼131.97). The area under the SROC curve was 0.87 (95%CI=0.84- 0.90). We found no evidence for publication bias (t=−0.84, p=0.42).Conclusion: Our meta-analysis indicates that SMI may have a high diagnostic accuracy in differential diagnosis between benign and malignant breast tumors. Thus, SMI may be a good tool for the diagnosis of breast tumors.

Background: Globally the non-communicable diseases (NCDs) are accountable for most of mortality and disability. The Lack of skilled human resources for health is one of the contributing factors for low screening coverage. Nurses plays a vital role, in the early detection and prevention of common NCDs. Objective of the study was to assess the effectiveness of nurse-led screening and intervention for common NCDs on risk factor modifications.Methods: Pre-experimental design was used in the present study. The study was done in slum area Indra colony Chandigarh. A total of 500 individuals aged ≥30 years were enrolled from 2,700 households. All the subjects were screened for hypertension, diabetes mellitus and oral cancer. However in female participants addition screening of breast, and cervical cancer was also done. WHO STEPS survey was used to assess the risk factor of common NCDs. The interventional package on risk factor modifications for prevention of common NCDs was developed and was delivered to all subjects during home visits. The follow up to assess risk factor modifications was done after one month. The primary outcome of the study was risk factor modifications and prevalence of common NCDs.Results: There was significant mean change in systolic blood pressure (0.65±6.31 mmHg), diastolic blood pressure (1.19±3.7 mmHg), body mass index (0.95±0.85 kg/m2), and waist circumference (1.5±1.46 cm) among subjects after one month of intervention (p value <0.05).Conclusions: The Nurse-led screening and intervention for common NCDs was effective in risk factor modification among studied subjects.

Introduction Early detection of breast cancer saves lives. Existing detecting techniques are invasive. Electrical bioimpedance is a noninvasive technique and has a high diagnostic potential. Methods An impedance value different from the normal can predict a physiological abnormality. The idea is to use a designed bioimpedance device to early detect breast cancer. A low-frequency current (1 kHz, 0.9 mA) is injected to each breast to measure the extracellular resistances. The resistances of the two breasts are then measured, and if there is a significant difference, warning is displayed. The performance was tested on a set of reference resistors, and the validation was done in vitro on (Na+Cl-) solutions and in vivo on a group of forty volunteer women. Results The results confirm that the electrical conductivity of an ionic solution is proportional to its concentration. The concentration and the resistance are strongly correlated (correlation coefficient of 0.97). The accuracy and the repeatability of the measures were satisfactory. Early detection means that we can detect small extracellular concentration variations into the breast (from 0.6 g/l). In vivo measurements made it possible to set the threshold at 50 ohm. If the difference between the two measured breast resistances is greater than this threshold, we advise the patient to consult a doctor promptly. Conclusion The difference between measured resistances of the right and left breast is a pertinent parameter to early detect the presence of a cancer. The lowest resistance value (RR or RL) can provide information on the breast affected by the cancer (right or left). Various improvements in the system are possible but already the results are encouraging. In the future, this system could be integrated into a bra.
