Lung cancer has high mortality and is often diagnosed at an advanced stage. Additionally, morphological abnormalities of tracheobronchial cells precede the carcinogenesis process and are based on molecular abnormalities. Moreover, Narrow-Band Imaging Bronchoscopy (NBI) has been developed to improve diagnostic accuracy. The objective of this study is to determine the diagnostic accuracy of NBI bronchoscopy in detecting morphological abnormalities of tracheobronchial cells and their relationship with p53 gene mutations.

This study is an experimental diagnostic study conducted on lung cancer subjects undergoing bronchoscopy procedures at RS Persahabatan from January to November 2023. NBI bronchoscopy procedures and bronchial forceps biopsies were performed on non-tumor lesions, followed by haematoxylin and eosin (HE) histopathological examination, as well as Polymerase Chain Reaction (PCR) Sanger sequencing for p53 mutations at the R175L, R248W, and R273C points. Reliability analysis was also performed.

A total of 105 subjects were included in the study analysis, predominantly male, smokers, with adenocarcinoma type cancer and advanced stage. Tracheobronchial cell morphological abnormalities were found in 34 subjects (32.4%), in the form of metaplasia, atypical cells, and tumor cells. Wild type p53 mutations at the R175L, R248W, and R273C points were found in all biopsy tissues. One metaplastic tissue had a p53 Codon 267 CT heterozygous mutation and one hyperplastic tissue had a p53 Codon 180 GC heterozygous mutation. The tortuous vascular pattern was identified as the best diagnostic criteria compared to other patterns with an area under the curve (AUC) of 78.4%; sensitivity 79.41%; specificity 77.46%; positive predictive value 62.8% and negative predictive value 88.7%. Inter-observer agreement in assessing vascular patterns was good with a kappa value of 0.88 (standard error 0.06; p-value <0.01). Edematous mucosa was associated with a tortuous vascular pattern on NBI bronchoscopy with an OR of 3.6 (95% CI 1.53-8.46; p-value <0.01). Subjects with a tortuous vascular pattern (OR of 21.89; 95% CI 6.50-73.71; p-value <0.01) and subjects with IB ≥ 600 (OR of 5.39; 95% CI 1.62-17.71; p-value 0.01) were associated with tracheobronchial cell morphological abnormalities."

"In cell cycle control, p53 acts as an emergency brake, where its important checkpoint function is to maintain the genome integrity by preventing the formation and proliferation of mutant cells. P53 activity is increased by DNA damage occurs caused by agents (such as radiation, UV light or drugs) or oncogenes. Mdm2 protein can inhibit the p53 activation, but oncogenes can inhibit Mdm2 or activate p53. If DNA damage occurs, then p53 prevents the cells from replicating their DNA by arresting the cell cycle, so that the cells can repair the damage. Alternatively, p53 instructs the cells to undergo apoptosis by inducing bax gene expression, so that irregular cell growth, and cancer can be avoided. Cancer, including oral cancer, oftenthuolved cells with altered p53. Exogenous factors, such as tobacco and alcohol, presumably plays a role in triggering p53 mutations. Several techniques, such as immunohistochemistry and PCR can be used to investigation ther etiology and development of oral cancer. This paper discusses the role on p53 in preventing the occurrance and proliferation of mutated cells that lead to cancer, including oral cancer."

Background: Treatment of multidrug-resistant tuberculosis (MDR-TB) using second-line drugs is known to have more side effects. Recent studies have shown concern about bedaquiline and delamanid that can cause a prolonged QT interval. This condition is a known risk factor for Torsades de Pointes, a lethal cardiac arrhythmia. This study sought to observe the condition among such patients treated in the study location.

Methods: This study was a prospective cohort study  of MDR-TB patients receiving bedaquilin in the outpatient clinic and inpatient ward of National Respiratory Referral Hospital Persahabatan, Jakarta, Indonesia between February 2020 to February 2021. Patients received 400 mg on week 0-2 (intensive phase) and followed by 200 mg 3 times per week (continuation phase) of bedaquiline. Sampling was carried out by consecutive sampling and data on subjects who met the inclusion criteria were taken from medical records.

Result: From a total of 71 subjects, all of them met the inclusion criteria. Prolonged QT interval was experienced in 18.3% patients. From eleven patients who experienced prolonged QT interval, two patients required hospitalization: one presented with nausea and gastric upset and one patient presented with dyspnea and palpitation. Prolonged QT interval occurred in initial phase and correlated with drug dosing. A mycobacterial culture conversion at month-6 was observed in those receiving multidrug regimens which include bedaquiline, quinolone, and clofazimine. There was a correlation between prolonged QT interval and hypocalemia. Treatment success rate was 46.5% without prolonged QT. Other outcomes included 4.2% died, 26.8% loss-to-follow up, and 4.1% treatment failed.

Conclusion: The use of bedaquiline MDR-TB appeared to be effective and safe across different settings, although the certainty of evidence was assessed as very low. Hypokalemia was correlated with the outcomes of patients receiving bedaquiline, particularly in those experienced prolonged QT interval."

"ABSTRAKBackground: diagnostic of pulmonary TB in HIV patients is a problem due to non specific clinical features, or radiological appearance. HIV patients with CD4≤200 cells/mL infected with M. tuberculosis have less capacity in containing M. tuberculosis, developing granulomas, casseous necrosis, or cavities. This condition is caused by weakend inflammatory which later reduced sputum production and may cause false negative result. This study aimed to assess differences in the positivity level of acid fast bacilli (AFB) and cultures of M. tuberculosis from non-bronchoscopic sputum (spontaneous and induced sputum) compared to bronchoscopic sputum (bronchoalveolar lavage) in HIV positive patients suspected pulmonary tuberculosis with CD4<200 cells/μL.Methods: this cross sectional study was conducted in adult HIV patients treated in Hasan Sadikin Hospital with CD4≤200 cells/μL suspected with pulmonary tuberculosis by using paired comparative analytic test. All patients expelled sputum spontaneously or with sputum induction on the first day. On the next day, bronchoalveolar lavage (BAL) was performed. The two samples obtained from two methods were examined by AFB examination with staining Ziehl Neelsen (ZN) and cultured of M. tuberculosis on solid media Ogawa on all patients. Positivity, sensitivity and increased sensitivity of AFB and culture of M. tuberculosis in the non bronchoscopic and bronchoscopic groups were compared.Results: there were differences in the positivity level of AFB with ZN staining between non-bronchoscopic and bronchoscopic groups which were 7/40 (17.5%) vs 20/40 (50.0%) (p<0.001). The differences between the cultures of non-bronchoscopic and bronchoscopic groups were 16/40 (40.0%) vs 23/40 (57.5%) (p=0.039). Bronchoscopic sputum increased the positivity level of the ZN AFB examination by 32.5% (from 17.5% to 50.0%) as well as on culture examination by 17.5% (from 40.0% to 57.5%).Conclusion: Bronchoalveolar lavage can improve the positivity level of smears and cultures in patients suspected of pulmonary TB in HIV patients with CD4<200 cells/μL."

"Pendahuluan: Bronkoskopi adalah tindakan semi operatif yang merupakan prosedur baku emas untuk penegakan jenis dari penyakit kanker paru. Kurangnya pengetahuan seputar persiapan dan tindakan bronkoskopi, kehilangan motivasi untuk melakukan tindakan bronkoskopi dan kecemasan akan prosedur tindakan bronkoskopi kerap kali membuat pasien menunda tindakan tersebut, dan hal ini tentunya dapat mempengaruhi prognosis dari penyakit kanker paru yang sudah buruk. Salah satu alasan pasien menunda tindakan tersebut adalah karena kurangnya pengetahuan akibat tidak tersedia nya media edukasi yang dapat memberikan informasi perihal persiapan dan prosedur tindakan bronkoskopi. Tujuan dari dilakukannya penelitian ini adalah untuk mengetahui pengaruh dari edukasi pre-bronkoskopi berbasis website terhadap pengetahuan, motivasi dan kecemasan pada pasien kanker paru yang akan melakukan tindakan bronkoskopi. Metode: penelitian ini menggunakan desain quasi experiment dengan metode pre test dan post test control group design. Penelitian ini menggunakan 21 responden pada kelompok kontrol dan 21 responden pada kelompok intervensi. Hasil: terdapat perbedaan tingkat pengetahuan, motivasi dan kecemasan yang signifikan pada pasien kanker paru yang akan melakukan tindakan bronkoskopi sebelum dan sesudah diberikan edukasi pre-bronkoskopi berbasis website pada kelompok intervensi dengan nilai signifikan pada α=5% (p<0,05). Rekomendasi: penyempurnaan dari model edukasi pre-bronkoskopi berbasis website agar dapat di aplikasikan sebagai metode edukasi utama dalam memberikan pengetahuan seputar persiapan dan tindakan bronkoskopi.

Introduction: Bronchoscopy is a semi-operative procedure that is the gold standard procedure for establishing the type of lung cancer. Lack of knowledge about the preparation and procedure of bronchoscopy, loss of motivation to perform bronchoscopy and anxiety about the bronchoscopy procedure often make patients postpone the procedure, and this can certainly affect the prognosis of lung cancer which is already poor. One of the reasons patients postpone the procedure is because of the lack of knowledge due to the unavailability of educational media that can provide information about the preparation and procedure of bronchoscopy. The purpose of this study was to determine the effect of website-based pre-bronchoscopy education on knowledge, motivation and anxiety in lung cancer patients who will undergo bronchoscopy. Method: This study used a quasi-experimental design with a pre-test and post-test control group design method. This study used 21 respondents in the control group and 21 respondents in the intervention group. Results: There was a significant difference in the level of knowledge, motivation and anxiety in lung cancer patients who will undergo bronchoscopy before and after being given website-based pre-bronchoscopy education in the intervention group with a significant value at α = 5% (p <0.05). Recommendation: refinement of the website-based pre-bronchoscopy education model so that it can be applied as the main education method in providing knowledge about bronchoscopy preparation and procedures."

Background: Pneumocystis jirovecii (P. jirovecii) is an opportunistic fungal pathogen that can be detected in the human lower respiratory tract without signs or symptoms of acute pneumonia or colonization. P. jirovecii colonization can develop into an infection known as pneumocystis pneumonia (PCP). PCP infection is commonly detected in HIV patients. However, patients without HIV can also experience PCP infection, especially in malignant patients. This study aims to detect P. Jirovecii colonization in bronchial lavage samples using polymerase chain reaction (PCR). Methods: This research is a cross-sectional study with descriptive analytics on patients suspected of lung cancer at Persahabatan Hospital. The research subjects were patients with suspected lung cancer who were selected according to the inclusion criteria. Data on clinical, radiological, laboratory and histopathological characteristics were taken from medical records. The patient will have a bronchial lavage sample taken during bronchoscopy for diagnostic purposes. The samples will be examined at the Parasitology Department Laboratory Universitas Indonesia for DNA extraction and the BRIN laboratory for PCR examination. Results: In this study there were 72 research subjects. The research subjects consisted of 51 men (70.8%). The mean age of the research subjects was 56.6 (9.95) years. Most of the research subjects had normal BMI (18.5-22.9 kg/m2). Most of the research subjects were smokers, either active smokers or former smokers, namely 50 people (69.4%). A total of 23 people (31.9%) had severe IB (IB >600 cigarettes per year). There were 23 research subjects who had a history of TB treatment, whether confirmed bacteriologically or clinically diagnosed, as many as 23 people (31.9%). A total of 26 people (36.1%) had 1 comorbid while 10 people (13.9%) had more than 1 comorbid. Based on histopathological or cytological examination of bronchial lavage, of the 72 research subjects, 50 people (69.4%) were diagnosed with lung cancer, 15 people (20.9%) had no lung cancer, and 7 people (9.7%) had no known diagnosis. Of the 72 samples examined, none showed positive PCR results (0%). Conclusion: The proportion of P. Jirovecii detected by conventional PCR examination in bronchial lavage samples from patients suspected of lung cancer was 0%. PCR examination to detect P. Jirovecii is not recommended for cancer patients who have just been diagnosed and have not received treatment."

In order to confirm the safety of a therapeutic vaccine for cervical cancer that is based on HPV E6 antigen, an interaction assay between the vaccine and the p53 protein is required. The aim of this study is to obtain a recombinant plasmid for expression of p53 recombinant protein that will be used in the interaction assay. The RevertAid enzyme and random hexamer primer was employed to obtain cDNA from HeLa cell that will be used as template in PCR using the Platinum Taq DNA Polymerase High Fidelity enzyme and p53 specific primer set, to generate a 1204 bp PCR product containing the p53 gene, with flanking SalI and PstI endonuclease restriction sites. Following restriction with SalI and PstI enzyme, the PCR product was ligated with the plasmid pQE 80L that has been linearized by restriction with the same enzymes. The ligation mixture was used for transformation of Escherichia coli TOP10. The presence of the inserted p53 DNA fragment in the recombinant plasmid harboured by the transformants was verified using PCR, digestion of recombinant plasmids, and sequencing. The results showed that the human p53 gene was successfully cloned into pQE 80L with a mutation at position 386 of the p53 nucleotide base sequence."
