Study of epidemiological behaviour of malaria and its control in the Purulia district of West Bengal, India (2016–2020)

Purulia is a malaria-prone district in West Bengal, India, with approximately half of the blocks defined as malaria endemic. We analyzed the malaria case in each block of the Purulia district from January 1, 2016, to December 31, 2020. As per the API, 20 blocks of Purulia were assigned to four different categories (0–3) and mapped using ArcGIS software. An exponential decay model was fitted to forecast the trend of malaria cases for each block of Purulia (2021–2025). There was a sharp decrease in total malaria cases and API from 2016 to 2020 due to the mass distribution of LLINs. The majority of cases (72.63%) were found in ≥ 15-year age group. Males were more prone to malaria (60.09%). Malaria was highly prevalent among Scheduled Tribes (48.44%). Six blocks were reported in Category 3 (high risk) and none in Category 0 (no risk) in 2016, while no blocks were determined to be in Category 3, and three blocks were in Category 0 in 2020. The exponential decay model prediction is oriented towards gaining malaria-free status in thirteen blocks of Purulia by 2025. This study will incite the government to uphold and strengthen the current efforts to meet the malaria elimination goals.

How to Predict Outcomes from a Biofeedback and Pelvic Floor Muscle Electric Stimulation Program in Patients with Urinary Incontinence after Radical Prostatectomy

Objectives: The objective of this study was to analyze the pre-operative and intra-operative variables that can condition urinary incontinence (UI) after radical prostatectomy (RP), as well as continence rate recovery during a pelvic floor rehabilitation program. Materials and Methods: A total of 72 cases with UI after RP were prospectively examined. All cases were homogeneously treated by the same surgeon, using the same RP technique. A combination of biofeedback (BF) and pelvic floor electric stimulation (PFES) performed by the same clinician and using the same protocol was used. Clinical, pathologic and surgical variables were analyzed in terms of 24 h pad test results (pad weight and pad-free status). Results: Prostate volume (PV) strongly varied from 24 to 127 cc (mean ± SD 46.39 ± 18.65 cc), and the baseline pad weight varied from 10 to 1500 cc (mean ± SD 354.29 ± 404.15 cc). PV strongly and positively correlated with the baseline pad weight (r = 0.4215; p = 0.0269) and inversely with the three-month pad weight (r = − 0.4763; p = 0.0213) and pad-free status (r =− 0.3010; p = 0.0429). The risk of a residual pad weight >10 g after the rehabilitative program significantly increased according to PV (p = 0.001) and the baseline pad weight (p = 0.002 and < 0.0001). In particular, PV > 40 cc and a baseline pad weight >400 g significantly (p = 0.010 and p < 0.0001, respectively) and independently predicted a 5.7 and a 35.4 times increase in the risk of a residual pad weight at the three-month follow-up, respectively. Conclusion: This is the first prospective trial whose primary objective is to verify the possible predictors, such as PV, that are able to condition the response to a pelvic floor rehabilitation program for UI after RP.

An Analysis of 20 Cases of Radiation-Associated Sarcoma, Including 4 Cases Treated by Carbon Ion Radiotherapy

Introduction Radiation-associated sarcoma (RAS) is one of the most life-threatening complications associated with the treatment of malignant neoplasms. Because all RAS patients have a history of radiotherapy, there have been no effective treatment options when RAS is not completely resected. Methods We retrospectively reviewed 20 RAS patients, including 4 unresectable cases treated by carbon ion radiotherapy (CIRT). Results The primary diseases targeted by radiotherapy included malignant lymphoma (n=4), cervical cancer (n=3), pharyngeal cancer (n=3), breast cancer (n=2), lung cancer (n=1), rectal cancer (n=1), maxillary cancer (n=1), synovial sarcoma (n=1), and benign neoplasms (n=4). The histological diagnoses of RAS included osteosarcoma (n=8), leiomyosarcoma (n=3), undifferentiated pleomorphic sarcoma (n=3), rhabdomyosarcoma (n=1), angiosarcoma (n=1), malignant peripheral nerve sheath tumor (n=1), spindle cell sarcoma NOS (n=1), and sarcoma not further specified (n=2). The median survival time from the diagnosis of RAS was 26 months. Eleven patients underwent surgery. Five of these patients achieved a continuous disease free status or showed no evidence disease. Four patients underwent CIRT. One of these patients with leiomyosarcoma achieved a continuous disease free status, and the other patient with osteosarcoma achieved a partial response. On the other hand, 2 patients experienced Grade 3 toxicities that required surgical treatment. Conclusion RAS originates from various types of diseases that are treated by radiotherapy and shows diverse pathological features. Complete resection achieves a good prognosis. CIRT can be an effective and feasible option for unresectable RAS.

Supporting countries to achieve their malaria elimination goals: the WHO E-2020 initiative

Background Malaria causes more than 200 million cases of illness and 400,000 deaths each year across 90 countries. The World Health Organization (WHO) set a goal for 35 countries to eliminate malaria by 2030, with an intermediate milestone of 10 countries by 2020. In 2017, the WHO established the Elimination-2020 (E-2020) initiative to help countries achieve their malaria elimination goals and included 21 countries with the potential to eliminate malaria by 2020. Methods Across its three levels of activity (country, region and global), the WHO developed normative and implementation guidance on strategies and activities to eliminate malaria; provided technical support and subnational operational assistance; convened national malaria programme managers at three global meetings to share innovations and best practices; advised countries on strengthening their strategy to prevent re-establishment and preparing for WHO malaria certification; and contributed to maintaining momentum towards elimination through periodic evaluations, monitoring and oversight of progress in the E-2020 countries. Changes in the number of indigenous cases in E-2020 countries between 2016 and 2020 are reported, along with the number of countries that eliminated malaria and received WHO certification. Results The median number of indigenous cases in the E-2020 countries declined from 165.5 (interquartile range [IQR] 14.25–563.75) in 2016 to 78 (IQR 0–356) in 2020; 12 (57%) countries reported reductions in indigenous cases over that period, of which 7 (33%) interrupted malaria transmission and maintained a malaria-free status through 2020 and 4 (19%) were certified malaria-free by the WHO. Two countries experienced outbreaks of malaria in 2020 and 2021 attributed, in part, to the COVID-19 pandemic. Conclusions Although the E-2020 countries contributed to the achievement of the 2020 global elimination milestone, the initiative highlights the difficulties countries face to interrupt malaria transmission, even when numbers of cases are very low. The 2025 global elimination milestone is now approaching, and the lessons learned, experience gained, and updated guidance developed during the E-2020 initiative will help serve the countries seeking to eliminate malaria by 2025.

Extracorporeal Shockwave Lithotripsy for Cystine Stones in Children: An Observational, Retrospective, Single-Center Analysis

Purpose: Cystinuria is a genetic disorder characterized by a defective reabsorption of cystine and dibasic amino acids leading to development of urinary tract calculi from childhood onward. Cystine lithiasis is known to be resistant to fragmentation. The aim was to evaluate our long-term experience with extracorporeal shockwave lithotripsy (ESWL) used as first-line urological treatment to treat cystine stones in children.Methods: We retrospectively reviewed the charts of all children who underwent ESWL for cystine stone. We assessed the 3-month stone-free rate, according to age, younger (group 1) or older (group 2) than 2 years old.Results: Between 2003 and 2016, 15 patients with a median (IQR) age at first treatment of 48 (15–108) months underwent ESWL in monotherapy. Median age was, respectively, 15 and 108 months in each group. The median (IQR) stone burden was 2,620 (1,202–8,265) mm3 in group I and 4,588 (2,039–5,427) mm3 in group II (p = 0.96). Eleven patients had bilateral calculi. ESWL was repeated on average 2.4 times, with a maximum of 4 for patients of group I, and 4.8 times, with a maximum of 9 for group II (p &gt; 0.05). ESWL in monotherapy was significantly more efficient to reach stone-free status for children under 2 years of age: 83% vs. 6.2% (p = 0.040). The median (IQR) follow-up of the study was 69 (42–111) months.Conclusion: ESWL appears as a valid urological option for the treatment of cystine stones, in young children. Even if cystine stones are known to be resistant to fragmentation, we report 83% of stone-free status at 3 months with ESWL used in monotherapy in children under 2 years old with cystinuria. In older children, the success rate is too low to recommend ESWL as a first line approach.

Cone beam computed tomography for detecting residual stones in percutaneous nephrolithotomy, a randomized controlled trial (CAPTURE) protocol

Introduction Percutaneous nephrolithotomy (PCNL) is the standard surgical treatment method for large kidney stones. Its aim is to achieve a stone-free status, since any residual fragments (RFs) after PCNL are likely to cause additional morbidity or stone growth. Enhancing intraoperative detectability of RFs could lead to increased stone-free rates and decreased re-intervention rates. Cone beam computed tomography (CBCT) has recently been introduced in urology as a feasible method for intraoperatively imaging RFs. The aim of this trial is to determine the added value of CBCT in percutaneous nephrolithotomy, by measuring differences in stone-related morbidity for patients with procedures in which a CBCT is used versus patients with procedures without the use of CBCT. Methods The CAPTURE trial is an investigator-initiated single-center, randomized controlled trial (RCT) in adult patients who have an indication for percutaneous nephrolithotomy. A contemporary percutaneous nephrolithotomy is performed. Once the surgeon is convinced of a stone-free status by means of fluoroscopy and nephroscopy, randomization allocates patients to either the study group in whom an intraoperative CBCT scan is performed or to the control group in whom no intraoperative CBCT scan is performed. The main endpoint is the stone-free status as assessed four weeks postoperatively by low-dose non-contrast abdominal CT, as a standard follow-up procedure. Secondary endpoints include the number of PCNL procedures required and the number of stone-related events (SREs) registered. The total study population will consist of 320 patients that undergo PCNL and are eligible for randomization for an intraoperative CBCT scan. Discussion We deem a randomized controlled trial to be the most effective and reliable method to assess the efficacy of CBCT in PCNL. Though some bias may occur due to the impossibility of blinding the urologist at randomization, we estimate that the pragmatic nature of the study, standardized circumstances, and follow-up methods with pre-defined outcome measures will result in a high level of evidence.

Address terms in New Zealand English: Tracking changes to the social indexicality of gendered terms of address

<p>Recent research has suggested that some conventionally masculine address terms are becoming more gender neutral in English speaking countries. This study examines the four most prominent gendered address forms in New Zealand English: mate, bro, man and guys in order to gain insight into the terms’ social indexicalities, and track any shifts towards gender neutrality. The study takes a mixed-methods approach to analysing two distinct data sets: four corpora of spoken New Zealand English and a data set collected from a range of current media sources. Results from this study suggest that mate is in retreat in younger New Zealanders’ speech, while bro may be increasing in usage as an unmarked form. Results also suggest that both man and guys have a largely gender free status and are being used frequently in New Zealand. These findings contribute to the growing interest sociolinguists are taking in informal address terms by providing an analysis of the interactional and social functions of address forms in New Zealand English.</p>

Near total laryngectomy: a single institutional experience

Background: Near total laryngectomy (NTL) aims to remove cancer of larynx and hypopharynx while maintaining a lung powered, prosthesis free voice. The oncological and functional outcomes of NTL have been encouraging but the surgical procedure is complex. In this study, we present our experience with NTL in order to encourage more ENT and head and neck surgeons to take up the procedure.Methods: Twenty-eight patients, who had undergone NTL at State cancer institute, Guwahati are analysed retrospectively for survival, disease free status, functional outcomes and complications.Results: There were two recurrences: one local recurrence which was salvaged by a completion total laryngectomy. The other patient had distant metastasis and died eventually. Overall survival (OS) was 96.43% and event free survival (EFS) was 92.86%. The patient who died had extra-nodal extension (ENE) on post op histology (p=0.274). Two patients failed to develop any speech had stenosis of the shunt. One of these was the only Salvage NTL case (p=0.057). Tracheostome stenosis, poor swallow and shunt stenosis were the common complications in our series. Most of them resolved with some intervention. Multiple complications were seen in the salvage NTL cases.Conclusions: Careful case selection and well executed surgery leads to acceptable results following NTL. Special attention should be paid to the salvage cases as they are prone to develop complications and failure to attain speech. Patients with adverse post-op histopathological examination (HPE), like ENE should be kept under close follow up.
