Authors: Kang Zheng , Chen Sijia , Shi Liwan , He Yipeng , Gao Xiang 
Published: June 2021

Background
Before generating radiotherapy plans for breast cancer patients, the choice of plan techniques (three-dimensional conformal radiation therapy (3D-CRT) and volumetric modulated arc therapy (VMAT)) should be made. This study investigated the performance of two geometric indices in aiding the choice of 3D-CRT and VMAT plans in women undergoing left-sided whole breast radiotherapy.

Materials and methods
119 patients, previously treated with left-sided breast radiotherapy (61 3D-CRT treatments and 58 VMAT treatments) from a single institution, were retrospectively studied. Two geometric indices, which were cardiac junction (CJ) index and pulmonary junction (PJ) index, were defined and the relationship between these indices and dose of organs at risk (OARs) were evaluated. Two-tailed Student’s t-test was performed to compare patient characteristics between 3D-CRT and VMAT. Linear regressions were calculated to investigate the association between geometric indices and absorbed dose of heart and left lung, including mean dose of heart (MHD), V5, V30 of heart, and mean dose of left lung (MLLD), V5, V10, V20, V30, V40 of left lung.

Results
The CJ index was strongly correlated with the MHD in 3D-CRT group and VMAT group. The linear regression formulas were MHD = 4826.59 ×CJ Index+310.48 (R = 0.857, F = 163.77, P = 0.000) in 3D-CRT plans and MHD = 1789.29×CJ Index+437.50 (R = 0.45, F = 14.23, P = 0.000) in VMAT plans. The intersection of the two formulas was CJ index = 4.2% and MHD = 512.33 cGy. The PJ index demonstrated a strongly positive correlation with MLLD in 3D-CRT group and VMAT group as well. The linear regression formulas were MLLD = 2879.54×PJ Index+999.79 (R = 0.697, F = 55.86, P = 0.000) in 3D-CRT plans and MLLD = 1411.79×PJ Index+1091.88 (R = 0.676, F = 47.11, P = 0.000) in VMAT plans, the intersection of the two formulas was PJ index = 6.3% and MLLD = 1180.46 cGy.

Conclusions
CJ index and PJ index could be used as a practical tool to select 3D-CRT or VMAT before generating plans. We recommend that VMAT plan is preferable when CJ index is greater than 4.2% and/or PJ index is greater than 14.6%, while 3D-CRT plan is the first choice in the opposite.

This study examines the long-run and the short-run relationship between the real exchange rate, GDP, FDI, inflation (INF), gross capital formation (GCF), Net official's development assistance (NODA), GNI, and trade balance in Uganda for the period 1994-2018. We used an Augmented Dickey-Fuller (ADF) test for the stationarity test, and we use the Johannsen cointegration approach to prove the existence of cointegration. The ADF tests show that the series was non-stationary in level but became stationary after the first difference. The Johannsen cointegration test indicates the long and short-run relationship between all the explanatory and trade balance in Uganda. Under such circumstances, a Vector Error Correction Model (VECM) is employed since the results offer more information than other data generation processes. Our findings are as follows: Real exchange rates, FDI, GCF and have a positive relationship with Trade balance. It means that Uganda can depreciate the Exchange rate to improve its Trade balance. The results proved the J-Curve effect's existence (i.e., the long-term impact of exchange rate on trade balance). The recommendations from this study are - Uganda's monetary policy management should emphasize more efforts on the stability and minimization of the volatility of exchange rates of the shillings since its movements affect international prices both negatively and positively, leading to either a decline or trade boost.

Abstract
Cyclic mastalgia is one of the most prevalent problems in women of reproductive age and sometimes it is so severe that it influences their activities and requires treatment. The available drug treatments for mastalgia are not satisfactory and most patients have inclined towards complementary and alternative medicine including herbal medicines. Therefore, in order to evaluate the effectiveness and side effects of herbal medicines conducting systematic review studies and meta-analysis seems essential, thus this systematic review was conducted with the aim of determining the effect of herbal medicines on cyclic mastalgia and its probable side effects. The databases of Pubmed, Medline, Embase, ProQuest, Scopus, Web of science, Complementary Medicine Database, SID (Scientific information database), Magiran and Iranmedex were searched from 1997 to 2020 and limited only for English and Persian languages. The studies were appraised according to the Cochrane Collaboration’s tool. Meta-analysis was conducted using RevMan software. Standardized mean difference (SMD) was calculated to assess an overall estimate of effectiveness for the continuous data. Odds ratio (OR) was calculated for dichotomous data. Thirty papers were included in the study. Meta-analysis of data demonstrated that herbal medicine was an effective method in reducing the severity of mastalgia compared to the placebo (SMD: −3.26, 95% CI: −5.05 to −1.46, p=0.00004). Subanalysis of data showed no difference between the effectiveness of herbal medicine on the severity of mastalgia compared to the pharmacologic treatment. This research demonstrated efficacy of herbal medicines in alleviating cyclic mastalgia. Therefore, these herbal medicines can be regarded as an alternative treatment for women suffering from cyclic mastalgia. However, due to the limited number of studies in relation to each specific herbal treatment, conducting further studies in this area is recommended.
Serum osteopontin can improve papillary thyroid cancer risk assessment of Bethesda III thyroid nodules: a preliminary study
Authors: Kars T U , Kulaksızoğlu M , Kılınç İ 
Published: June 2021

Objective
Thyroid cancer can be detected in 5–10% of patients with thyroid nodules. Management may be a challenge if fine-needle aspiration biopsy yields Bethesda III findings. Most of these cases undergo surgery and are ultimately found benign. Our aim was to evaluate whether serum osteopontin can accurately estimate thyroid cancer risk in cases with cytologically Bethesda III thyroid nodules and, thereby, decrease the number of unnecessary surgical interventions.

Design and Methods
We obtained blood samples of cases with repeated cytologically Bethesda III thyroid nodules before surgery, and followed up the pathology results after thyroidectomy. We evaluated serum osteopontin from 36 patients with papillary thyroid cancer and compared them with 40 benign cases.

Results
Serum osteopontin levels in patients with papillary thyroid cancer are significantly higher than in benign cases (mean serum osteopontin: 10.48 ± 3.51 ng/mL vs6.14 ± 2.29 ng/mL, P < 0.001). The area under the receiver operating characteristics curve was 0.851, suggesting that serum osteopontin could have considerable discriminative performance.

Conclusions
In our preliminary study, high serum osteopontin levels can predict the risk of papillary thyroid cancer in thyroid nodules with Bethesda III cytology. Further studies are necessary to confirm these findings.
