Coronal plane stability of cruciate-retaining total knee arthroplasty in valgus gonarthrosis patients: A mid-term evaluation using stress radiographs
Authors: Chaiyakit Pruk , Wattanapreechanon Pichayut 
Published: August 2024

BACKGROUND
Total knee arthroplasty (TKA) using implants with a high level of constraint has generally been recommended for patients with osteoarthritis (OA) who have valgus alignment. However, studies have reported favorable outcomes even with cruciate-retaining (CR) implants.
AIM
To evaluate the coronal plane stability of CR-TKA in patients with valgus OA at the mid-term follow-up.
METHODS
Patients with primary valgus OA of the knee who underwent TKA from January 2014 to January 2021 were evaluated through stress radiography using a digital stress device with 100 N of force on both the medial and lateral side. Gap openings and degrees of angulation change were determined. Descriptive statistical analysis was performed for both continuous and categorical variables. Inter-rater reliability of the radiographic measurements was evaluated using Cronbach’s alpha.
RESULTS
This study included 25 patients (28 knees) with a mean preoperative mechanical valgus axis of 11.3 (3.6-27.3) degrees. The mean follow-up duration was 3.4 (1.04-7.4) years. Stress radiographs showed a median varus and valgus gap opening of 1.6 (IQR 0.6-3.0) mm and 1.7 (IQR 1.3-2.3) mm and varus and valgus angulation changes of 2.5 (IQR 1.3-4.8) degrees and 2.3 (IQR 2.0-3.6) degrees, respectively. No clinical signs of instability, implant loosening, or revision due to instability were observed throughout this case series.
CONCLUSION
The present study demonstrated that using CR-TKA for patients with valgus OA of the knee promoted excellent coronal plane stability.
Tracing the Origin of Metal Ions in Mississippi Valley-Type Ore Deposits: Constraints from Lead Isotope Studies of Black Shales from the Midcontinent United States
Authors: Morris Noah , Potra Adriana , Samuelsen John R. 
Published: August 2024

Abstract
Mississippi Valley-type (MVT) lead-zinc ore deposits found in the midcontinent United States have isotopic signatures that indicate the potential involvement of a single highly radiogenic source mobilized by hydrothermal fluids or the mixing of two sources of Pb with differing radiogenic signatures. A genetic link between black shales and major MVT ores has been thought to exist because of (1) the presence of mature hydrocarbon and brine fluid inclusions within many MVT ores, (2) the association of the hydrothermal fluids that are linked to MVT ore formation with organic compounds and oil-like droplets, and (3) the highly radiogenic nature of the ores. The analysis of 69 shale samples from 21 stratigraphic units from across the midcontinent United States revealed variations in Pb concentrations and isotopic compositions across different Cambrian- to Pennsylvanian-age shales. Shales with high organic carbon content, particularly those of Pennsylvanian age, displayed elevated Pb abundances, suggesting their formation under anoxic conditions was conducive to the preservation of organic carbon binding with Pb ions. However, the Pb isotope signatures of most black shales are generally less radiogenic than the ores, suggesting that they were not a source of radiogenic Pb. Several samples of the Devonian-Mississippian Chattanooga Shale and the Ordovician Polk Creek Shale have significant quantities of radiogenic Pb that more closely resemble those of the MVT ores. This suggests that certain shales may have directly interacted with the hydrothermal fluids that precipitated the MVT ores. Some shales may have acted as an aquitard as the hydrothermal fluids were migrating through the subsurface, causing some shales to become more enriched in radiogenic Pb than others.

Purpose:
The purpose of this study was to evaluate clinical outcomes after tendon transfers in the setting of reverse total shoulder arthroplasty (RTSA).

Methods:
PubMed and Embase were searched according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines to find primary clinical studies of any type of tendon transfer in the setting of RTSA.

Results:
Overall, 17 studies (level of evidence [LOE] I: 1, LOE II: 0, LOE III: 3, LOE IV: 13) met inclusion criteria, with 300 shoulders. Most patients were female (56.7%), with an average age of 68.7 years (range 19 to 89) and a mean follow-up of 46.2 months (range 6 to 174). 11 studies reported outcomes after combined latissimus dorsi and teres major transfer (LDTM) while eight studies reported on latissimus dorsi transfer only (LD). Improvements in commonly reported subjective and functional outcome measures were as follows: external rotation +32° (LDTM) and +30° (LD), flexion +65° (LDTM) and +59° (LD), Visual Analog Score −5.4 (LDTM) and −4.5 (LD), subjective shoulder value +43.8% (LDTM) and +46.3% (LD), and overall Constant score +33.8 (LDTM) and +38.7 (LD). The overall complication rate was 11.3%, including tendon transfer ruptures (0.7%), instability (3.0%), infection (2.0%), and nerve injury (0.3%). The all-cause repeat operation rate was 7.3%, most commonly for arthroplasty revision (5.3%). Subgroup analysis revealed that lateralized implants with tendon transfer resulted in markedly greater improvements in Constant score, flexion, ER1, and ER2 while medialized implants with tendon transfer had markedly greater improvements in Visual Analog Score, subjective shoulder value, and abduction.

Conclusion:
Patients undergoing tendon transfer of either combined LDTM or latissimus dorsi alone in the setting of RTSA have markedly improved subjective and functional outcomes. A moderate incidence of complications (11.3%) was noted in this patient population.
Hormonal Therapy and Endometrial Cancer: Latest Advancements
Authors: Mehboob Riffat 
Published: August 2024

Endometrial cancer ranks as the sixth most common malignancy among women worldwide and fourth most common cancer of female reproductive system, with an incidence rate that has increased by 132% over the last 30 years [1]. It is uterine cancer which develops in inner lining of uterus (endometrium). Common symptoms include abnormal uterine bleeding, pelvic pain, and an enlarged uterus. The factors that have increased risk of getting endometrial cancer are obesity, diabetes, hypertension, menopause age, infertility, hormonal imbalance and polycystic ovary syndrome (PCOS). According to a report in 2023, it was projected that there would be over 66,000 new cases and more than 13,000 deaths attributed endometrial cancer in United States [2]. The high incidence and mortality rates are fueling growing concerns among women globally. The pathological mechanism involves invasion of stromal and myometrial tissues, often associated with Phosphatase and tensin homolog (PTEN) mutations, KRAS2 mutations, and microsatellite instability. Endometrial cancer has been categorized into type 1 and type 2 based on histological features.
Traditional methods for treatment of endometrial cancer (surgery, chemotherapy) are effective and essential but recent advancements in the field of endometrial oncology have raised hopes of people, particularly hormonal therapy is emerging as promising option for non-toxic treatment in type 1 (estrogen dependent) and recurrent endometrial cancer. Estrogen and progesterone work antagonistically and the endometrium, which is responsive to hormones, grows when exposed to estrogen and stops growing when exposed to progesterone during the menstrual cycle. The exposure to estrogen hormone for long time causes hormonal imbalance which increases thickness of uterus walls and provide site for cancerous cell growth. As a result, hormone therapy uses progesterone to counter the effects of estrogen and decrease tumor growth. The success of hormone therapy relies on the existence of hormone receptors such as progesterone receptors (PRs) in cancer cells. Patients with grade 1 and 2 endometrial cancer undergo standard hormonal therapy which yields high response rates such as progestin and aromatase inhibitors. Tamoxifen is considered as second line hormonal agent due to low response rate. These medications play a key role in targeting specific hormonal pathways in endometrial carcinoma treatment and management. Hormonal therapies offer a favorable safety profile to manage recurrent tumors after chemotherapy.
As the landscape of hormonal therapy for endometrial cancer evolves rapidly, the integration of traditional hormonal treatment with targeted therapies represents a significant advance. Personalized medicine—understanding the distinctive hormonal characteristics of each tumor—will shape hormonal therapy for the future. Endometrial cancer research and clinical trials hold promise for developing more effective and less invasive treatments.

Published: August 2024

In most healthy individuals, intermittent fasting during Ramadan, which occurs just once a year, could have positive effects on metabolic consequences. That even though there are several exceptions to fasting, many Muslims who have medical issues choose to fast. This may have a significant influence on their health if not addressed properly. The health consequences of Ramadan fasting have recently sparked renewed study. This study is designed to evaluate the effect of fasting in Ramadan on the level of some metals and minerals compare these levels with a control group that is not fasting during Ramadan and show the effect of Ramadan on the health of fasting people. It was a study consisting of two categories. The first group was composed of 50 people (males and females) who fasted during Ramadan, while the second group was composed of 50 people who ate and drank during Ramadan. From both groups tacked 5 ml of venous blood to estimate the concentration of metals which include: cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), calcium (Ca), chromium (Cr), magnesium (Mg), potassium(K) and sodium (Na) during Ramadan month. The present study found that the concentration of cadmium, lead, copper and magnesium increase significantly in fasting group as compared to control group (with p- value =0.001 for Cd and p= 0.000 for other). whereas no significant difference in concentration of calcium, sodium and potassium between the fasting and control group. The results showed that fasting in Ramadan not affect the level of calcium, sodium and potassium, whereas the levels of cadmium, lead, copper, magnesium and chromium were affected, since they increased during fasting except chromium decreased. However, observing healthy food guidelines while fasting throughout Ramadan can lessen these alterations.

Conclusion: Pediatric rotary files resulted in superior quality of obturation with minimal chair‐side time, hence they form an integral part of pediatric dentist’s armamentarium and can be considered as the standard of care in primary molar pulpectomies.
Oxidation Resistance of NiCrAlY Coating Prepared by Arc Ion Plating
Authors: YU Bo , CHANG Xiao-peng 
Published: August 2024

With the rapid development of the aviation industry, the working conditions of the aero-engines have become even worse. With a rise in inlet temperatures, the aero-engine blades are easily oxidized at high temperature, which consequently reduces their service life. MCrAlY coating (M refers to Fe, Ni, Co, etc.) has good high temperature oxidation resistance. It is considered to be an effective method to solve the problem of high temperature oxidation of aero-engines blades, and has gradually become the current domestic and foreign scholars focus. Arc ion plating is a mature technology for the preparation of MCrAlY coating, which has been paid much attention. Based on the arc ion plating process, and Ni-base superalloy GH4133 for aero-engines blades, coating the surface with NiCrAlY coating, after heat treatment, high temperature oxidation resistance test, at a constant temperature of 920 ℃, continuous oxidation test for 192 h, the micro-morphology, microstructure and oxidation process of the samples were analyzed by SEM, XRD, and EDS. The results: 1) NiCrAlY coating has a high density, there are many fine particles distributed on the surface of the coating, the surface is smooth, no micropores, pits and other defects, the coating and the matrix material formed a close bonding state; 2) after heat treatment, the particles on NiCrAlY coating surface are arranged more closely, the coating changed from NiAl phase to Ni3Al phase, which improved the high temperature oxidation resistance of the coating; 3) during the initial stage of high temperature oxidation, a uniform and dense protective layer of Cr2O3 was formed on the surface of the coating, which effectively prevented the oxygen from diffusing into the inner of the coating, thus greatly improving the anti-oxidation performance; 4) during the oxidation process, the interdiffusion of Cr occurs at the interface between the coating and the substrate, mainly in the form of Cr element diffusing from the coating to the substrate. When the oxide layer Cr2O3 cracks or peels off, a new oxide layer can be formed after the substrate contacts with oxygen, which decreases the rate of oxidation weight gain and continues to play the role of high temperature oxidation protection.

Published: August 2024

This paper systematically studies the compressive strength of recycled coarse aggregate concrete with different dosages of polypropylene fibers at high temperatures and the influence of polypropylene fibers on the bond performance between recycled concrete and steel bars at high temperatures. The research results indicated that as the temperature increased, the compressive strength of the concrete decreased. Fibers can improve the compressive strength of concrete, but this effect needs to be controlled within a certain range. As the temperature increased, the bond strength between the concrete and steel bars decreased, while the bond slip increased. The addition of fibers improved the bond performance between the recycled concrete and steel bars, which was mainly reflected by increasing the bond strength and reducing the bond slip. With increasing fiber content, the bond strength between the recycled concrete and steel bars first increased and then decreased. When the fiber content was 0.12 %, the bond strength between the recycled concrete and steel bars was the highest. In addition, a calculation model of the bond strength between steel bars and recycled coarse aggregate concrete with fibers after exposure to high temperatures was established.
