    Abstract Introduction: Phlebotomy, i.e., the collection of blood samples, is one of the most commonly performed procedures in almost all hospital settings. The phlebotomy center is the first point of contact for patient samples with the laboratory services. The patient load visiting the phlebotomy center of a rapidly developing hospital is very variable and unpredictable. This leads to staffing issues related to a number of phlebotomists. The actual phlebotomy procedure requires only a few minutes, but the total time includes the patient's arrival to departure from the phlebotomy center. In this study, we have attempted to assess the adequacy of the number of phlebotomists in our sample collection center and to determine how many patients can be attended to comfortably by each phlebotomist. As the sample load increases, the burden on phlebotomists also increases, and they may or may not express the strain of it. We attempted to determine the cut-off patient numbers above which request for additional personnel has to be put into the hospital administration.
    Materials and methods: This was a prospective, hospital-based, observational study carried out in the outpatient sample collection center section at the All India Institute of Medical Sciences, Bibinagar, Telangana, over a period of one month, i.e., December 2022. The movement of 1200 patients was observed for the phlebotomy procedure. Patient details, the time taken for registration, waiting time, and phlebotomy time were noted, along with the hindering factors in the phlebotomy center.
    Observations and results: There were 680 males and 520 females. The mean time for patient arrival to departure from the phlebotomy center and the mean waiting time was 9.8 minutes and 6.5 minutes, respectively. Various reasons for increased phlebotomy time were pediatric patients, anxious patients, postprandial sample patients, difficulty in finding veins, etc. Though the estimated capacity of the phlebotomy center is apparently satisfactory with four personnel, many hidden causes for time loss were observed.  Conclusion: An adequate number of trained and effective phlebotomists is the first step in ensuring the success of any laboratory service, and while deciding on this "adequate number," not only the direct effort, but also the indirect effort, operational needs and emergencies have to be kept in mind. Each phlebotomist in a six-hour shift can comfortably attend 30 to 35 outpatients for phlebotomy. When this number exceeds it, additional staff has to be added. Adopting measures to reduce the waiting time for phlebotomy procedures will improve the phlebotomy center's service. The study provides a basis for the modification of a number of phlebotomists in order to ensure optimal patient service.

    Abstract Aim: The aim of the study was to investigate whether the surface geometry or topography of implant abutments affects the retentive strength of prosthesis cemented with zinc phosphate on standard machined, sandblasted, and grooved implant abutments and to compare the results between them.
    Materials and methods: Fifteen similarly shaped implant abutments (MDcpk61; MIS Implant Technologies Ltd.,) (height 6.0 mm and 6-degree taper) were divided into three groups (
    Results: For zinc phosphate cement, F = 30.53 (>3.59 for
    Conclusion: Circumferential grooves on implant abutments give better retention when compared with standard machined (plain) and sandblasted abutments despite marked difference.
    Clinical significance: Retention of restoration depends on the surface of the abutment as well as the luting agents used. Incorporation of retentive grooves can enhance retention of prosthesis, especially in situation of short abutments.

    Abstract Aim: This study was intended to evaluate the knowledge and clinical skill of anesthesia residents pertaining to various intubation techniques employed in craniofacial surgery.
    Materials and methods: A cross-sectional survey research design was employed in this study. A self-administered questionnaire survey was used to validate the knowledge and clinical skill of anesthesia residents pertaining to various intubation techniques employed in craniofacial surgery. In this regard, a preliminary study with a convenience sample of 156 anesthesia residents studying in various medical institutions across South India was conducted so as to assess the knowledge and clinical skill of anesthesia residents pertaining to various intubation techniques employed in craniofacial surgery. This study, while limited in sample size, benefits the craniofacial surgeons and anesthetists as target readers to assess the knowledge and clinical skill of anesthesia residents pertaining to various intubation techniques employed in craniofacial surgery.
    Results: The results of this study reveal that majority of the anesthesia residents encountered craniofacial surgery during their residency period. However, only 19.87% have performed various intubation techniques that are employed in craniofacial surgery. Nearly 38.46% of the participants felt that blind awake intubation is the most difficult intubation technique to employ in the head-and-neck region and requires expertise. Nearly 78.84% of the participants felt that special training is required for handling craniofacial surgical cases under general anesthesia.
    Conclusion: The results of this study reveal that there is a dearth of knowledge and clinical exposure among anesthesia residents regarding various intubation techniques employed in craniofacial surgery. Educational and quality improvement initiatives in various intubation techniques could enhance anesthesia residents' knowledge and clinical exposure in managing various craniofacial surgical cases.

    Abstract Background: Single field Orthovoltage radiation is an acceptable modality used for the treatment of nasal cutaneous cancer. However, this technique has dosimetric pitfalls and unnecessary excessive exposure of radiation to organs at risk (OAR). We present the clinical outcome of a case series of cutaneous nasal tumours using a novel technique incorporating an optical scanner and a 3-dimensional (3D) printer to deliver treatments using parallel opposed (POP) fields.
    Materials and methods: The POP delivery method was validated using ion chamber and phantom measurements before implementation. A retrospective chart review of 26 patients treated with this technique between 2015 and 2019 was conducted. Patients' demographics and treatment outcomes were gathered and tabulated. These patients first underwent an optical scan of their faces to collect topographical data. The data were then transcribed into 3D printing algorithms, and positive impressions of the faces were printed. Custom nose block bolus was made with wax encased in an acrylic shell; 4 cm thick using the printed face models. Custom lead shielding was also generated. Treatments were delivered using 250 KeV photons POP arrangement with 4 cm diameter circle applicator cone and prescribed to the midplane. Dose and fractionation were as per physician discretion.
    Results: Phantom measurements at mid-plane were found to match the prescribed dose within ±0.5%. For the 26 cases in this review, the median age was 78.5 years, with 15 females and 11 males. 85% of cases had Basal cell carcinoma (BCC); 1 had squamous cell carcinoma (SCC), one had synchronous BCC + SCC, and 1 had Merkel cell carcinoma. Twenty-one cases had T1N0 disease, 4 had T2N0, and 1 had T3N0. Dose and fractionation delivered were 40Gy in 10 fractions for the majority of cases. The complete response rate at a median follow-up of 6 months was 88%; 1 patient had a refractory tumour, and one patient had a recurrence. Toxicities were minor with 81% with no reported side effects. Three patients experienced grade 3 skin toxicity.
    Conclusions: Utilization of optic scanner and 3D printing technology, with the innovative approach of using POP orthovoltage beams, allows an effective and efficient way of treatment carcinomas of the nose with a high control rate and low toxicity profiles.

    Abstract Purpose: To create and investigate a novel, clinical decision-support system using machine learning (ML).
    Methods and materials: The ML model was developed based on 79 radiotherapy plans of brain tumor patients that were prescribed a total dose of 60 Gy delivered with volumetric-modulated arc therapy (VMAT). Structures considered for analysis included planning target volume (PTV), brainstem, cochleae, and optic chiasm. The model aimed to classify the target variable that included class-0 corresponding to plans for which the PTV treatment planning objective was met and class-1 that was associated with plans for which the PTV objective was not met due to the priority trade-off to meet one or more organs-at-risk constraints. Several models were evaluated using double-nested cross-validation and an area-under-the-curve (AUC) metric, with the highest performing one selected for further investigation. The model predictions were explained with Shapely additive explanation (SHAP) interaction values.
    Results: The highest-performing model was Logistic Regression achieving an accuracy of 93.8 ± 4.1% and AUC of 0.98 ± 0.02 on the testing data. The SHAP analysis indicated that the ΔD
    Conclusions: The trained model achieved satisfactory accuracy and can be used by medical physicists in a data-driven quality assurance program as well as by radiation oncologists to support their decision-making process in terms of treatment plan approval and potential plan modifications. Model explanation analysis showed that the model relies on clinically valid logic when making predictions.
